Was looking at dino 5w-30's this weekend for a few cars that I take care of. Decided to go with the Mobil clean 5k. I can get a 5qt jug at wally for $11 (vs $13 for YB) The oil is SM/CF GF4 rated and meets the GM, chrysler and ford specs for conventional oil. No other Dino 5-30 is "C" rated also. I'm givin it a shot in my tacoma in about 3 weeks. See how it does on a 5k OCI which is all I can do. For filters I plan on running White Purolators on all the cars, but for my tacoma I plan on running the FL400S is which "oversized" but closest to the OEM toyota filter size. OR a L20195 Purolator.
