Conventional or Synthetic Oil?
#16
New Jeep Owner
Hello,
I just bought my first Jeep.
2000 Jeep Cherokee Sport.
I'm in the process of taking care of the tires and getting an inspection.
Now i hear everyone talking about oils.
I don't know what oil type or weight was used. Now the jeep has 187,000. runs great. Body is straight and minimal rust.
Any ideas?
Thanks

Switching to synthetic on a very well used engine has the potential to cause leaks. I've been using mobile1 since 5k and the engine still looks new at 60k.

I spent a lot of years working with a local engine builder years ago, and initially I swore by conventional, he swore by synthetic. As time went on, and engines came and went I saw more and more the benefits of running synthetic; I became a believer myself.

This is an outdated way of thinking. Engine seals have been able to tolerate synthetic without the risk of leaking for decades now. I have had numerous vehicles over the years that I bought with well over 100,000 miles and have switched to synthetic on every one them and have never once seen an increase in leaking.

this...
also the other myth stated in here about not being able to switch back that is very false i had a vehicle that depending on how much money i had at time of oil change depended on if it got conv. or syn. and it was a bit of an experiment as well never had any issues...and if your gonna use a good filter and rotella t6 you can run a good 5k-7k oil change interval a guy on here posted about it on here and the oil lab said he could go that high and be safe
i love rotella shop i work in uses it in all the diesels i use rotella t6 in my vw tdi and will be using it in my jeep (may sound weird but rotella smells good)
