PPPffftttt, mechanics dont know crap, I have been doing this for... 30 some odd years... or so (not to bad for an 18 yearold eh). Really though some mechanics arent that smart. For example I had a kerback mitsu mechanic "specialest" said that I should drop a 4g63 block in to my car. Head wont fit, trans wont fit, IT WONT FIT. He said "ya it will". Then again I know a guy who works on my buddys lightning and he KNOWS his crap. So its iffy, depending on who you talk to. As far as I am concerend this topic is officially dead as.... of.... NOW.

 

you are tiring to tell me a guy that has been building motors for 35 years don’t know **** on what is good and what can be bad. LMAO oh **** that some funny stuff that is like saying AutoZone is more knowledgeable that the engineers that built the car LOL. hey you may think it is just me but i would much rather take advice from someone that rips the motor apart and has seen how different problems effect the internals of the motor rather than just some mechanics that takes a compression test than tells ya you may need a new motor. don’t get me wrong there are several mechanics out there that also deal with internals but not all day. what it comes down to is sure it COULD happen but it might not but why take a chance if it may be that one motor that has a head gasket that has not leaked with conventional oil but than dose when u put synthetic in. there are a lot of things that could happen but they don’t always happen it is just a risk that is taken when you go from conventional oil to a hypo racing or super syn oil.
