Stopped buy the local Autozone to pick up some car wash soap to try and get rid of hard water spotting problems. While there, I found that today through June 25th, Autozone has 5 quarts of full synthetic plus a Mobil1 filter for $25.99. Savings is about $17. I believe that you can get up to 2 per day, so stock up. And don't forget that you need 1 extra quart for the Tahoe.

 

I wish it was Pennzoil. But, then again, Mobil 1 full synthetic ain't half bad.

 

My local walmart sells them for $21.98 mobil 1 5w-30 for trucks and suvs
