AMSOIL is a waste of money on a Yaris and you would be better served buying more expensive gasoline with detergents (Shell).

Spending $3 more for Mobil1, over Amsoil XL, and $2.50 more for Mobil1 XP, over Amsoil HP would be the silliest thing I could ever do, imo. No thanks. Shell in my area is cheap and 10% ethanol, I stay away from it.

btw, Yes Mobil1 is factory fill in cars like my GTO. At the time, seems like most owners I knew made the switch to Amsoil and RP.....oh well.
