Default Re: Use of synthetic motor oil
Go ahead and run the 5W-20. When your piston skirts all collapse don't go crying to me. No engine EVER designed can run a 20w or 30w at operating temp. Pistons and Journal clearances are designed for one or the other weight. Toyota can send their bulletin, then they can repair all the junk engines that will follow. Watch and See. BTW, the bulletin doesn't allow 0w-20 usage in the earlier 1NZ motors. Read the Owners manual on motor oil weight selection, and high speed driving.
