That and a lot of people seem to think that running dino oil for a long time and then switching to syn will cause leaks. Some say that is an ole wives tale, some believe in it... Who the hell knows anymore????

 

Well in my Saturn, at first I burned a lot more oil. Then after a few changes, I was getting better 'oil mileage' than with dino. There is an explanation as to why this happens, but I don't remember. Look up 'Bob the oil guy', should be more than any one person needs to know...

 

gtx highmileage = the ***** and the *****
