TSoA,
I know of several mechanics that are ASE master certified in all areas, have worked on cars all their lives (and in racing too!), and truely know just about nothing about engine oils.
They swear by certain oils, saying that one protects much better than the other, the only reason the engine is still running is because of this oil, that no other oil is better. Heck, I even know of one master tech. that knows EVERYTHING about cars and trucks, and he said that me running 15w-40 in a gas engine was just bad for it.
They offer no facts or proof, just sayin' what they think. And saying that an engine blows up on 15w-50 M1 when pushed hard is pure fallacy.
If this man is so knowledgeable, why does the 5w-50 protect so much better than the M1? Let me guess...because it says Castrol on the bottle?
If you respect your mechanic TSoA, then fine...it's great you have someone you can trust.
You knew when you posted this topic that you'd be met with fierce resistance and speculation to your claims...dare I say you wanted to start an argument.
I'm not trying to tick you off TSoA, but you've provided absolutely no fact, and your line of reasoning makes absolutely no sense as we know of many engine that are pushed very, very hard that do not just come apart with M1 15w-50.
Sorry TSoA, the burden of proof is on you, and no one should believe you when you just continue to speak second-person to us simply relying upon what someone said.
For instance, I was just reading Four Wheeler magazine, and they were saying they wanted to give their truck the best protection.
They used Royal Purple and a Fram Toughguard filter.
Does that mean they are the best bets?
Remeber the old sayin": "They said are the biggest liars in the world..."
