If you look at the printing under the Autozone name it lists Mobil 1 m/c oils

That is about what I pay for Amsoil 20-50, actually I think it a little less. No taxes.

 

Autozone has MC oil listed under small engine. With the coupon it comes to 8.99 qt. I posted this because I don't have Advanced Auto near me.

 

i have absolutely no complaints with using Castrol 20w-50 across the board.

 

Blaines Farm Fleet sells it for 8.99 all the time.

 

Mobil 1 Full Synthetic 15/50 at Wally's - 5 quarts for $25.

 

I am lucky. My local Wally World carries and this is the normal everyday low pricing!
