As far as I know. You order on line and pick up and pay in your local store. They will NOT ship.

What's the difference between 5w-40 and 5w-50? What's the benefit? Thanks

5w-50 is heavier when hot with better tolerance for the heat our turbos generate.

I see. I've been using 0-40 or when available 5w-40. The weather in San Diego is pretty much perfect most of the time. If I go with 5w-50 would that be better? Thank you.

Yes. Great product. Stays in spec longer over the drain interval. Does not shear down like M1 0W40. Porsche A40 approved.

That's a good price. Sometimes you can double-dip, and use the Mobil $12 (per case, limit 2) rebate.
