You seriously revived this thread to call another member a derogatory name?

No, to compliment their sense of humor.

OK, sorry, I took your post the wrong way. My apologies.

It is a funny comment. That's what I often tell people if they want to prevent their car from wearing out. Don't drive it.

No problem, I really did laugh out loud when I read that. Just to clarify, this was one of, probably 20 threads that I dug up via google in a search for threads on synthetic versus conventional oil during the winter.

 

[Garak]

With respect to that topic, I've used a lot of conventional with success in our winters. I only wish I had the weather from your state in the winter.

With what's normally specified in the manual of a modern vehicle will do well in winter.

and in a religious context brother mcrn.

I know this thread is a year old, but I just wanted to toss in that if it was my vehicle and salt was the only reason for me to follow the severe service interval, and I was concerned about start up wear. I'd use a quality synthetic oil and follow the normal service interval.

The normal service interval is usually 2x as long as the severe interval, and 1 synthetic change costs less than two conventional oil changes. So it costs you less for the same mileage, you also save time doing half as many oil changes, and you get the better oil protection and properties of synthetic oil. Sounds like a win/win/win to me.

At cold temp's it is the start that contributes to engine wear, particularly in the valve train. Even the lightest 0W-20 oil you can buy is still way heavier than optimum; heavier grades just exacerbate the problem.


so in theory would say a vehicle that lives in Miami technically have less wear and a longer potential life then say a vehicle in my or your neck of the woods?

That's why there are cold pumpability tests within grades, and pour point is almost irrelevant.

The only longer potential life in Miami will be from lack of rust.
