synthetic oils
Hello everyone.
I am wondering about synthetic oils. I was reading on another forum and there was mixed thoughts of it.
A lot of what I want to know is, some people were saying it can cause seals to leak, other says it stops this. I know once you go to synthetic you should never change back.
I'm mostly thinking if it should be done for my moms pathfinder. High mileage (200+ miles on it) and the reason I'm thinking about it is because her oil is pretty dirty all the time, and they were saying the synthetic oil can help clean it up. On the down side (really good though), its a 92 and doesn't leak any oil. I don't want to tell her to switch to then find out it caused an oil leak.
I would also like to hear any ones thoughts on synthetic oils vs. traditional oils.
thank you
