Synthetic oil or not?

[waddie]

I ran Schaeffer's 10-30 18,000 miles on a 1996 tacoma 4 cylinder, with oil analysis, and it performed beautifully. Synthetics are great because they keep viscosity longer and handle heat better but also look for a friction modifier that won't build up in the engine. Schaeffer's is by far the best I've found.

Oh I've heard of plenty of folk running Schaffer's long drain. But Supertech Synth???? Only if Schaffer's or AMSOIL become a supplier.

Could be. I've heard that WalMart sources their Supertech by the cheapest bidder for each batch, so it's possible (though unlikely)...
