Ten bucks off your 5 qt. purchase of 0W-20 or 0W-30 AFE syn oil.
Most US Wally World stores sell 5qt containers of M1 for $22.
AutoZone currently has an 'Oil Change Special' offering 5 qt oil and an M1 filter (much better than the standard Fram garbage) for 29.99.
Subtract the $10 and you've got a pretty decent deal.
Typical "save the Earth" propaganda.

I'm not convinced that 0W-30 will save much over the 10W-30 I usually run, but I might give it a try at my next change, due in a few months.
FWIW!
