What Happens If You Don't Change The Oil In Your Audi For 84,000 Miles....

[lewdog]

What happens if you don't change the oil on your Audi TT for 84,000 miles? Take a look.

This turned up on Reddit's ever-excellent r/JustRolledIntoTheShop. There's no explanation for why this car was allowed to atrophy like this, but it's possible the person who uploaded this picture immediately recoiled in horror and had to go puke before posting anything further.

Here's the picture in high res.



Part of the reason I am always scared to buy a used car. Many people have no idea about basic maintenance and drive their cars hard.

[Lonewolf Ed]

That engine is tres fuqued.

[Bugeater]

The fact that it made it to 84k before failing is actually pretty impressive.

[The Franchise]

The fact that it made it to 84k before failing is actually pretty impressive.

This.

[Bearcat]

Drove a cargo van for a job in college and mentioned to my manager a couple times that it sounded pretty rough... and when it finally seized up on the highway one day, they found out it had gone roughly 15,000 miles without an oil change. So yeah, 84,000 is quite impressive.

[Donger]

Presumably synthetic oil?

[ThaVirus]

An old boss of mine's wife drove some old ass Honda Civic. He said "once those cars hit 100k miles you don't even need to change the oil anymore"..

[SAUTO]

Looks like they used pennzoil

[Eleazar]

If it was still running then that's very impressive

[mlyonsd]

Wait, there's oil in cars?

[Rain Man]

My car uses synthetic oil and it's supposed to only be changed once every 10,000 miles. It makes me really nervous and I keep asking the dealer if it's time to replace it.

[ChiefRocka]

Needed some TLC.

[stumppy]

Thats what I was thinking.
Looks just like the motor I had to tear down that belonged to a 'By God my dad always used penzoil and he never had any problems so thats why I'll always use penzoil' customers.
They had changed the oil and filter every 3000 miles from the day it was new. Penzoil 10-30. That truck made it to about 130,000 miles then it started making noise.

I've used synthetic in older cars that don't require it and still only change it every 10,000.

I do, however, change the oil filter every 5000.

[Gonzo]

I'm sure Sauto can definitely tell us a story or two but when I was a tech at Saturn in Wichita, we'd get cars in all the time that needed complete overhauls due to customer stupidity.
I had a Pontiac Grand Prix come in once with 40k on it. Never had an oil change and it looked a lot like that. 3.8 L with a supercharger.... Owned by a 20 year old girl of course.
I actually brought her in to look at her engine and told her that after I rebuild the fucker, she needs to change the oil every 3k. She was just oblivious. 3 grand later I believe she got the point.

[TLO]

That's hard to look at.

[Baby Lee]

Or, as Inmen calls it, barbecue.

[Fairplay]

Simply Red drives an Audi maybe its his.

[Stewie]

I have a buddy that bought a Chevy S-10 pickup in the 90s and the engine crapped out before 10K miles. They dropped a new engine but he was pissed. He never changed the oil, only topped it off when needed. It made it to 100k when he decided to trade it in. God knows what the next owner experienced.

[Miles]

Looks like some good BBQ crust.

[KCrockaholic]

An old boss of mine's wife drove some old ass Honda Civic. He said "once those cars hit 100k miles you don't even need to change the oil anymore"..

Wtf.

[ThaVirus]

Wtf.


Idk. He said on his wife's last oil change, it was all basically sludge that came out.

That, somehow, led him to the conclusion that old Civics don't need oil changes anymore.

What could/should you do to ensure that deposits aren't slowly tightening a carbon noose around your engine's throat?

[Miles]

What could/should you do to ensure that deposits aren't slowly tightening a carbon noose around your engine's throat?

Change you oil more often than 84k.

[milkman]

Change you oil more often than 84k.

So, 80k is good?

[Bugeater]

So, 80k is good?
I would do it at 50k just to be safe.

[Miles]

I would do it at 50k just to be safe.

Completely. Just make sure its synthetic and you are good. May not get that brisket looking crust with synthetic though.

[displacedinMN]

Just heard about the same thing at the dealership about warranties.

A guy with a full size Ram had never changed the oil so at about 90K it went to hell.

It was the only time Dodge did not honor the extended warranty.

[Miles]

My car uses synthetic oil and it's supposed to only be changed once every 10,000 miles. It makes me really nervous and I keep asking the dealer if it's time to replace it.

BMW says 15k miles for an oil change when they are paying for it the first few years when new. With synthetic 10k is not unreasonable at all.

[TrebMaxx]

My BMW dealer would change my oil once a year regardless of mileage during the four year free maintenance period.

[KC native]

What could/should you do to ensure that deposits aren't slowly tightening a carbon noose around your engine's throat?

Use good oil. Doesn't have to be synthetic.

[Hoopsdoc]

I've got a 2000 Pontiac Grand Am with 280,000 miles on it. It had 20,000 on it when I got it. I rarely change the oil in it, maybe every 25,000 miles.

Did I mention the car is a steaming pile of monkey poo?

[FlaChief58]

Change it at 5k no matter what they say

[Bearcat]

http://www.edmunds.com/car-care/stop-changing-your-oil.html

Yeah, I didn't know any better and didn't bother to research until about 9 years ago when I noticed my car would say it was at 75% oil life at 3,000 miles... and the manual actually says "at least one per year" if it the oil life doesn't hit 0. Like Rain Man alluded to, that 3,000 mile thing is so ingrained, it's hard to shake, even when the manual says differently.

[Pablo]

I go with a 5k interval myself. Seems to be alright.

[beach tribe]

An old boss of mine's wife drove some old ass Honda Civic. He said "once those cars hit 100k miles you don't even need to change the oil anymore"..

not as often anyway.
losing a little viscosity might help compression in an WELL broken in motor.

I said might.

What synthetic do you guys use? I've been using Mobil 1 for a decade now.

[BigMeatballDave]

Conventional or Synthetic?

[penguinz]

Wasting $ if you do that

[KC native]

What synthetic do you guys use? I've been using Mobil 1 for a decade now.

Rotella T6.

Several of the guys on the Mazdaspeed forum have paid for oil analysis on their motors over the years and the T6 (despite being oil for diesel motors) holds up better and keeps the turbo bearing from wearing out.

YMMV.

[Bearcat]

Conventional or Synthetic?

Mine is conventional and the computer tells me to change it every 5-7k miles or so.... granted, I usually change it on the safe side of that, since 3k is etched into my brain.

[BigMeatballDave]

Wasting $ if you do that

Definitely. 5000 is for conventional.

[Pablo]

Conventional or Synthetic?

Conventional.

[BigMeatballDave]

Rotella T6.

Damn, it's cheaper than Mobil 1. I may consider switching.

[KC native]

Okay.

03 Malibu with a 3.1 v6. This is the 6th car I've had with that engine and I've used synthetic in all of them. Solid engine.

[KC native]

03 Malibu with a 3.1 v6. This is the 6th car I've had with that engine and I've used synthetic in all of them. Solid engine.

I don't know if I'd switch to the T6 then.

The Mazdaspeed guys like the T6 because it doesn't break down under heat. The turbo bearing gets cooked with synthetics that don't handle heat very well. A lot of them use the Pennzoil Platinum.

Edit: It's technically not the right viscosity for our motors but after a couple hundred miles, the heat breakdown brings the T6 to the right viscosity.

[Otter]

I try to know when to change my oil by looking at it every two weeks. If you can't see the dipstick thru the oil it's time to change. The pretty good research I've done is that Mobile 1 filters and synthetic are currently the best available unless you want to go Nascar driver.

[Eleazar]

5k

[FlaChief58]

Wasting $ if you do that

I'm ok with spending a few extra bucks on oil changes vs engine changes

[ThaVirus]

What if you have a hike mileage car, say 160,000+, that you've been using standard oil for at least the past 4 years. Would making a switch to synthetic be a smart move?

[Brock]

Without reading any posts and trying hard not to be sexist I would not at all be shocked to find that this car was being driven by a woman. :eek:

[BigMeatballDave]

Not at all, because you're still going further between changes with synthetic.

[penguinz]

Waste of $.

[Brock]

I would probably not go 10,000 miles between changes in a car with 160k, synthetic or not. That's just me.

[BigMeatballDave]

I've done it, but I don't blame you.

[Jimmya]

I use Mobil 1 synthetic, and change it around every 5-7000 miles. Still change the oil myself.

[88TG88]

I have a Maserati, those change their own oil.

[BigMeatballDave]

Still change the oil myself.

So do I. No way am I paying someone to do it.

[Bugeater]

So do I. No way am I paying someone to do it.
It's actually not all that much more to take it to a quick lube place, but every goddamn time I take it to one of those places I've had trouble getting the filter off the next time because those cocksmokers always put an oil filter wrench on it and tighten the holy fuck out of it. So I do it myself if at all possible.

[DC.chief]

I had a new customer come in the other day with a 2010 challenger rt with 33k on it for an odd noise from the engine and it had never had an oil change. It's wild how oblivious people are. We put a jasper reman in it that cost him 6819 bucks

I run t6 in my turbo car but change it every few months, maybe 1k miles tops.

[KC native]

I daily drive my Speed3. I drop it every 5k on the dot (rotate the tires too).

I'm reasonable on it. I drive it hard occasionally but don't beat it up.

[Perineum Ripper]

I use Castrol Edge in my truck with a Fram Tough Guard filter..change every 3000 miles even though everything says I can go 5000-10000..all together it's like $35 and I'm completely fine with paying that because I plan on keeping the truck for a long time..so I want to keep the engine in as good of shape as possible..it only has 70000 miles and I plan on keeping it until it has over 200000..I put on about 7000 a year

If people only keep their vehicles for 4-6 years..and drive less than 15000 miles a year regular oil is going to be good enough if they change every 3000..it won't make sense financially to put in synthetic oil..if people keep vehicles longer then I would suggest paying an extra $5-15 every few months

Fram filters are junk. If you value your vehicle i would suggest a different brand. Wix or Napa Gold is are decent. My preference for mine is K&N or Royal Purple

Wix filters and Castrol oils in all my cars and trucks for years.... Never had an issue...

Well except when the cam in my 1998 surburban went flat after 299K miles...

A got a bug up my ass a year ago and had the timing belt changed, just because of the age (and it has an interference motor). The mechanic handed me the old belt and said, "You just wasted $1,200" It was perfect.

LMAO

[BigMeatballDave]

Something I used to do before I started using synthetic was adding a quart of automatic transmission fluid and letting it idle for 30 mins before changing.

ATF is a high-detergent fluid. It can help remove sludge.

For the same cost, if not cheaper then the TG and definitely cheaper than the EG you can get a Wix that is much higher quality. Or the Napa Gold which is a re-branded Wix.

[GloryDayz]

Oil snobs crack me up...

I think changing your oil matters more than which you use. It's funny how people who tend to know which oil is better, and are willing to pay more for the better oils, are also the ones who actually change their oil.

Raise your hand if you've changed your oil and filter at least every 5,000 miles (usually 4,000 [but never 6,000!!!]), use Penzoil (and perhaps others!!!!), and have a vehicle that's got 200,000+ miles with no engine issues?

So the point isn't lost that oil snobs can spend a lot more money on better oil, but the magic is in actually changing it, and the filter (FRAM too!!), every 4,000'ish mikes (give-or-take 500 miles).

[Beef Supreme]

If I was Audi, I would use this as advertising, assuming the car was still running up until this point.

[BigMeatballDave]

Oil snobs crack me up...

I'm definitely a snob when it some to conventional and synthetic.

I haven't used conventional in more than a decade.

Synthetic is better. That is a fact.

[Fairplay]

I have a blended oil and take it to the dealership for them to change every 7500 so that's what I do.

That's what they recommend I'm good with that.

[Frosty]

Even though I use Mobil 1, I generally change the oil when the manual says to do it - every 5000 on my Forester and every 10,000 on my wife's CR-V. They boys' cars get less than 3000 miles a year on them, so I do those once a year. I use stock filters on the Sub and the Honda and NAPA Gold on the boys' cars. We don't drive a lot, with mostly shorter trips, and it can get very hot here in the summer and very cold in the winter, so I like to play it safe.

The next step is synthetic manual transmission fluid in my Forester so it doesn't feel like I am shifting through tar on cold mornings.

[Frosty]

I've had many a battle with my Dad over Pennzoil. However, in the early 90's, my wife was driving a '87 Toyota Tercel that she had bought new. She pretty much only drove it to work in town - about 6 miles a day round trip - and she drives like a granny. The Tercel started to run rough and the mileage went from the low 30's down to about 20 mpg. We had a mechanic look at it.

He told us the oil had sludged up (I saw it - looked like jello) because of the Pennzoil and the short trips. He claimed there was paraffin in the oil and we weren't getting the engine hot enough to keep it flowing. He suggested we changed to a different brand of oil or started getting the car up to highway speeds occasionally. We changed to Havoline without changing driving habits and never had another problem. :shrug:

I know it's a hotly contested theory but it seemed to be our experience. Pennzoil is probably perfectly fine for the average driver but it didn't work in our situation.

[GloryDayz]

I'm definitely a snob when it some to conventional and synthetic.

I haven't used conventional in more than a decade.

Yes, yes it is...

And I trust you change your oil too, right?

10,000 on Mobil 1 and I change the filter every 5000.

[Eleazar]

So, SAUTO and others, what would it take to get the above engine back in order? $3,000? $5,000?

[98 SR20]

I usually change my oil and filter once a year. Mobil 1 and a WIX filter. Going to start changing twice a year now, I drive my car less than 10,000 miles a year. I'm probably good with once a year oil and filter change though.

[BigMeatballDave]

So, SAUTO and others, what would it take to get the above engine back in order? $3,000? $5,000?

I'm no expert, but I do have some knowledge. I have no idea on price, Jason can answer that, but that head will have to come off, and a valve may be burnt. If a portion of a valve broke off, then there could be piston damage.

This cannot be repeated enough: the owner of that car is a fucking moron.

My Silverado crossed the 200K barrier last Thursday. I change the oil every time the idiot light comes on or every 6K miles whichever is first (normally the idiot light comes on around 5,500 it seems, but it has gone to 6K without coming on a handful of times).
I use a Fram TG and Valvoline MaxLife synthetic blend. Knock on wood, I've never had an issue other then general maintenance except for a water pump that went out a few years ago.

[GloryDayz]

Filter will get clogged long before the Synthetic oil needs to be changed.

I agree, but while I'm under the truck/car, I guess I've always just drained the oil and went with new.

LOL, maybe they need a 10,000 mile filter...

Gotcha.

I didn't think about the bottom end. I bet there is sludge in the oil pan. I'm wondering is the pick up was clogged or at least headed that way.

One of the first jobs I ever had was as a clean up man at a giant gm dealership in the service department, mopping bays between jobs, throwing away trash, stuff like that. One of the things I remember about that place was that every mechanic had at least one can of Marvel Mystery Oil on his tool box. Anybody know what that stuff would be good for? Anybody ever use it?

It can be used in the crankcase and in the gas tank.

Supposed to keep things clean. I've never used it.

Change your oil like you're supposed to, and don't run your fuel tank on empty and you'll be okay, for the most part. Mine rarely gets below 1/4.

My car uses synthetic oil and it's supposed to only be changed once every 10,000 miles. It makes me really nervous and I keep asking the dealer if it's time to replace it.

I know. Me too. I just can't bring myself to wait that long.

[SAUTO]

One of the first jobs I ever had was as a clean up man at a giant gm dealership in the service department, mopping bays between jobs, throwing away trash, stuff like that. One of the things I remember about that place was that every mechanic had at least one can of Marvel Mystery Oil on his tool box. Anybody know what that stuff would be good for? Anybody ever use it?

Lots of guys use it for air tool oil.

Oh yeah, that's probably it.

8k full castrol synthetic

I'm still trying to convince my Dad that he doesn't need to re-fill his tires on his Honda with nitrogen.

Me: Dad, you don't have to use nitrogen to re-fill your tires. It's a fucking rip-off. Compressed air is mostly nitrogen anyway. You're a fucking engineer, for God's sake!

Dad: Yes, BUT IT'S IN THE MANUAL!!

It can be used in the crankcase and in the gas tank.



Supposed to keep things clean. I've never used it.

What kinds of problems does running on low fuel lead to?

It can cause the fuel pump to overheat on some vehicles.

[SLAG]

I usually go to Firestone and have them do a Synthetic Kendall Blend on my 03' Suburban with 217k Miles - every 3k-5k miles - I try to keep it closer to 3k because of the high mileage - it leaks some oil out the rear main too but not too bad really

I also use the Firestone Synthetic Blend on the 07 Silverado with 84k miles - no complaints so far.

I did just buy a 03' SAAB with 104k miles and Plan to only use Mobil 1 Synthetic as that is what is suggested when I pop the hood.

Any complaints with my plan?

[BigMeatballDave]

What Frosty said. Plus, you risk pulling sediment from the bottom of the tank.

Most people don't know that gasoline serves as a coolant and lubricant for the pump.

Other than buying the Saab?

When I had my Silverado, I read quite a bit how it was easy to burn up the fuel pump by consistently running under a quarter tank so I always filled it when it got to a quarter. I haven't read that it's an issue with my Sube so I generally run it 'til the fuel light comes on and then fill it. :shrug:

Or on a Dodge Dakota, it makes the transmission not want to shift out of first gear. Weirdest thing ever.

Sounds like a slow trip to the gas station

You have no idea, it's annoying as fuck when it happens, especially if I have to go on to a busy street to get to a gas station. I know better than to let it get that low but sometimes I get busy and don't pay attention and it stings me.

[BigMeatballDave]

Yeah, that's really odd.

[Couch-Potato]

Damn! I owned an Audi 5 years back and cannot believe this pic! ...My audi was constantly in the shop and the transmission didn't make it to 80k+ miles. Hard to believe the driver went that long without any issues!?!?!?

Dude... I just fought a dodge 2500 diesel twelve rounds for fucked up issues like this.

I won by ko but GOD DAMN it put up a hell of a fight

[lewdog]

Had no idea you shouldn't run gas tank near empty for that reason on fuel pump. I never let mine get below 1/4 anyway but that's because of my OCD.

[Perineum Ripper]

My grandpa and dad always told me that it is easier to keep the top half of the tank full rather than both halves..they said so you don't have to pay as much each fill up and you won't burn up your fuel pump

[RedDread]

I do changes every 5K with full snyth and Oil Filter every 10K. Am I wasting cash?

Oil will last longer than filter will.

[BigMeatballDave]

Yeah, you should flip your method.

[Baby Lee]

My gramps retired from Mobil [repairman on the locomotive line in MO Bottoms], so every car since forever has been Mobil1 with Mobil1 filters. Filter change between 3-5K, full change @15-17K.

All Chevy [V8 EFI] and Pontiac [SC 3.8 V6].

'Merka, fuck yeah!!
