jwhjr Posted January 12, 2013 Share Posted January 12, 2013 If every 5k you might as well just put conventional in it. Quote Link to comment Share on other sites More sharing options...
1968 Posted January 12, 2013 Share Posted January 12, 2013 Keep in mind it has a 15 piece timing chain set that requires oil pressure for tensioning and plenty of lubrication for all the plastic guides. Quote Link to comment Share on other sites More sharing options...

Walleyehooker Posted January 16, 2013 Share Posted January 16, 2013 I run full synthetic in everything I own because it is the best oil out there. Why go half way? I run it about 6000 miles in the vehicles but I change it myself and not worried about saveing $20 a year. Quote Link to comment Share on other sites More sharing options...
fishnowworknever Posted January 16, 2013 Share Posted January 16, 2013 I run full synthetic in everything I own because it is the best oil out there. Why go half way?

Whoaru99 Posted January 17, 2013 Share Posted January 17, 2013 There isn't really any good reason I've heard why a synthetic oil would cause oil consumption or leaks. OTOH, if your engine is already burning oil and or leaking it, I would not expect it to burn or leak any less synthetic. Quote Link to comment Share on other sites More sharing options...
Macgyver55 Posted January 17, 2013 Share Posted January 17, 2013 There isn't really any good reason I've heard why a synthetic oil would cause oil consumption or leaksI've never heard it causes leaks, only that the smaller molecules of the synthetic are able to get past very small crevices, where the larger molecules of conventional oil cannot.If all your engine seals and gaskets are in good condition, synthetic oil shouldn't leak any more or less than any other oil.

SkunkedAgain Posted January 17, 2013 Share Posted January 17, 2013 Since this thread has slightly morphed, I'll ask if using one of the high mileage oils would help the OP's situation? Quote Link to comment Share on other sites More sharing options...
Walleyehooker Posted January 17, 2013 Share Posted January 17, 2013 I remember years ago they would say synthetic would cause leaks if you switched over but I think that was a myth. Never hear that anymore. Quote Link to comment Share on other sites More sharing options...
Scott K Posted January 17, 2013 Share Posted January 17, 2013 Mac nailed it. It wont make a seal leak, but you will notice more leaks while using it, because of the thinner compound of it, thinner/smaller will leak out of the small holes, that werent leaking with conventional oils, that are thicker/larger molecules.
