Hey Guys, Happy holidays. I hope everyone is safe out there.
I was over hearing a conversation of a few mechanics and some of them said that they wouldn't reconmend Sythetic Oil over Regular. Now I love my Mobile one in my car, but is running sythetic bad?? I can't believe that but the question is running through my mind because thats what one of the mechanic said. I know mixing sythetic and reg. is bad but I find it hard to believe Pure sytheic is bad for you car...and yes I over heard the entire conversation of the mechanics so I didn;t leave anything out.
Can anyone shed a little light?

WRONG! Synthetic oil is NOT the cause of oil leak. It's because of other problem like the gaskets are already getting brittle, and the more refined synthetic oil can seep through the cracks. The only bad thing about synthetic oil is cost.

Mobil 1 did have problems that caused gaskets and seals to shrink, especially if conventional oil had been in use for a long time. That problem was deminished when they upgraded to "try-synthetic" and became even less prone to the problem with the latest change.
The claim of the synthetic blends (not full synthetic) is that they give you most of the advantages of synthetic without the concern of increased oil consumption or leaks. These blends were made with high milage engines in mind, or so they claim.
My personal opinion is that synthetic truly is superior, but is also overkill. The performance of today's dino oil is very closely aproaching the performance level of synthetic oil.
I use Mobil 5W30 dino oil and I change it every 3,000 miles. As much as I drive, that turns out to be about every 5 weeks.

My brother-in-law (a mechanic) gave me sh!t for running synthetic in my cars, stating that it wasn't needed for street vehicles, only race engines. He said the cost wasn't worth it.
This just solidified my stance as to the benefits of synthetic fluids, because if it's good enough for a race engine, it certainly won't hurt my street motor, and extra cost bedamned! It's cheap peace of mind!
