Yeah, I would run the Amsoil 5W-20, but we don't have it around here where I get the ASL for my truck, and I don't like ordering it over the net. I have been running 10,000 mile OCI's on the Accord since it was bought new with Mobil 1 5W-20, but all the new concerns with it have caused me to try something new.
I think I might just go with the Pennz, but I was curious if the Havoline Syn was even better than the dyno Havoline.
