When is it time to change to synthetic oil?

[~The Jester~]

And now, a brief word from our sponsor Royal Purple. hehehehe


Anyways, we all know oil pressure is a good thing. I was running Castrol 20w-50 in my car, and it carried about 80 psi down the track at 13.45 I was happy, the engine was "protected" I thought, with the good "racing" oil.

Then, a friend explained to me that TOO MUCH oil pressure is a BAD thing. Think of all that oil pressure trying to keep your cam, crank, pistons from moving. All the engine internals actually have to work AGAINST the oil pressure.

Did NOTHING else to the car except switched to Castrol Syntec 10w-30 and presto! 13.20 all ******* day long at about 45 psi oil pressure. Eventually I switched to synthetic in the whole car, tranny, rear end, the whole bit. Synthetic oil. It just works better. Plain and simple.
