Do Delo and Mobil Delvac come in 10w-30 weights? I've found that alot of Wally Worlds don't carry Rotella 10w-30 and Advance Auto can't order it either.
I believe I recall someone just recommending Delo 10W-30 recently so I think they make it based on that. I've had trouble finding the Rotella 10W-30 and finally found some at a local Menards another forum member suggested I look at.
If it's not for a diesel engine, try Valvoline VR1, it has higher calcium for extra detergency and higher zddp, like 1300 ppm zinc and 1200 ppm phos, and comes in 10w30 at Murrays, which is part of CSK so you may be able to find or order in your area.
