If you find an oil you like that is available on the subscription service, shipping is free (maybe it's because I also have the amazon prime, but I don't think so ), and the product is further discounted when using the subscription service.
For my jeeps (we have a few in the family), I get a Valvoline shipment every 2 months.. beats running around looking for it.
Stores around here seem to be stocking less buffer, and seemed to be fine with leaving the shelf empty for a little while.
For my TDRam, I'm down to only changing the oil twice a year, use a synthetic 5w-40 for the winter and a dino 15w-40 for the summer.
So I tend to buy it when I find it and put it on the shelf, Wallyworld seems to have the best prices.
Till recently, seemed we were at wallyworld every other week anyway.
JR, for the
http://www.amazonsupply.com/ , if you can find the same product on there, yes any order over 50 bux is shipped free and usually 2 days.
Not all items on the regular amazon.com are eligible for the basic free shipping.
I always double check amazonsupply first, one needs to create a new account there.
