oh please, hundreds of people run full synthetic in their cars without leaks or problems. If your car leaks with synthetic oil then it means there's a problem, and it's not with the oil.

I run Walmart Supertech 10w-30 full synthetic in mine and it's awesome oil for the price.

the only problem with that ryan, is when you run synthetic in our older 5.0s that generally have high milage it will tend to leak out more then if you run the standard oil. This has been shown time and time again. I have heard so many times that people are running regular oil, and then switch to synthetic and have problems. I would just use regular oil to begin with if you have high milage.

Yeah that's very true but that's because the gaskets or seals are worn and need replacement, if the engine is in good condition it will not leak with synthetic oil.

very true, but alot of people would rather just run a higher viscosity of oil to "seal" up those little leaks instead of going through the work. Expecially people that are injured =P.

So run high mileage synthetic

or we could run what our motors were designed to run on =P
