Does anyone know if there are any risks/negatives involved in switching back and forth between mineral-based and synthetic oil in our engines?

 

i believe that once you go synthetic you should stay synthetic forever and never switch back. Maybe this is a wives tale, but I have been told this many times and tend to believe it.

I admit this provides NO explanation for how hybrid oils work.

 

I've heard that older versions of synthetic will turn to a gel when introduced to dino oils. That's why you were supposed to stick with just one or the other. But supposedly with todays formulations this does not hold true anymore.

I don't actually know this to be true it's just what I heard.
Check out yhe forums at http://theoildrop.server101.com/cgi/ultimatebb.cgi tons of good info there.

 

This used to be accepted as true, but almost all of today's synthetics state on their labels that they are compatible with conventionals.

i always use synthetic on my car... no need to get cheap with something as important as motor oil...

 

Actually there is quite a bit of evidence that seems to say that there is no need to get expensive with motor oil.

 

Thanks for the input everyone
