Where to buy 5-20w synthetic

For me, Amsoil XL 5w-20 costs about $4.75/qt shipped to my door, when purchased by the case. But M1 5w-20 is probably the best OTC synthetic IMHO, so I personally wouldn't bother looking for other ones. You may want to give M1 EP 10w-30 a try instead...it may actually offer better wear protection than 5w-20 due to its thicker oil film.
