About oil change, and the synthetic oil
 

Sorry if it is a Q.

Do you use synthetic oil for oil change in your car?

I have this link here about oil change: http://www.edmunds.com/car-care/top-...motor-oil.html

But the technical terms are a bit too technical for me.

we use synthetic in our trucks, changing at 10k.

10,000 on synthetic is good. I do this, but I change the filter every 5000.

I use synthetics in my vehicles from the start and change every 10K. BUT you should not switch to synthetic oil if u have regularly changed your oil in an older vehicle with 75k + miles. Your seals and gaskets can start leaking.

We do too. We only change our oil in our big trucks once in the winter when things slow down at work. They usually have 4000 to 6000 miles on each one by this point, though.

This is not true for anything past the earliest versions of synthetics.

LMAO. not true.

I switched my 09 ram to synthetic at 150k because apparently when a dealership says "oil changes for life" it's only their life. She's now at 205k leak free and running hard.

All of you have testified that after using the synthetic oil, your car last a long time. But how do you know if you use the regular oil that would not achieve the same result?

I think it was originally thought that Synthetics had detergents in them, and overtime, would remove buildup around seals that weren't leaking soley because they were blocked up by said buildup.

I have no idea if that is, or ever was true.

Wear protection aside, I use synthetic because I get twice the mileage out of it vs conventional.

I heard this, too.

WIth proper maintenance the car will last the same time, just with synthetic you require less oil changes.

If it starts leaking, it was already leaking. Synthetic will make an existing leak much more obvious.

Probably, yeah.

Though Synthetic has been proven to hold it's viscosity better than conventional.
