Hey Charles, My mechanic tell's me that 30,000 mile's between oil change's is way too much because the viscosity of the oil break's down too much, making the oil useless, 5000 mile's for conventional motor oil and 7000 mile's for full synthetic, but I also believe people are wrong all the time and have a hard time admitting it, including my mechanic, I use full synthetic all the time in both my vehicle's, what are your thought's on full synthetic motor oil?

My guess is the switch to higher viscosity is not providing better protection but reduces the amount of oil lost in the combustion process.Because it is thicker less of it blows by into the exhaust.This indirectly lessens the time the engine is running with less than optimal oil volume.The potential down side is at lower ambient temps.the oil will take longer to circulate through the motor on a cold start.Also a slight decrease in mpg as stated as the engine works harder to move the thicker oil.Mixing viscosity won't cause any harm.My theory has always been that 5w30 with 1000 miles on it is no thicker than 5w20 with 0miles on it.

Also, using motor oil that has a different viscosity rating from...

Viscosity in motor oil is expressed in a range.
