So it's been quite hard for many people to find Mobil 1 5W-40 (sold as truck & SUV w/ the yellow cap), but I have found that several Checker stores are now stocking it around here. Hopefully this is true nationwide.
Anyway, this week they are selling 1 Qt. jugs for $4.99 each!
Just thought I'd pass it along because this oil is teh win - especially in the brutal AZ heat.
