I looked on the walmart website and it showed that the oil i wanted was in stock. We made a 40 mile round to pick it up just to find out it wasn't. So I had to order online. That process was very satisfying. The oil showed up 1 day after ordering. So good job on that, not so good at showing something at the store that wasn't available

BIG TWINS NEED THIS

I was using a well known 20w-50 for break-in and just switched to Mobil 1 15w-50. The minute I started my big twin it turned over quicker, was quieter (engine) and seemed smoother (transmission). At this price no reason for Dino oil. Try it, You'll like it!

Great Product, Great Price

I have an air cooled sports car that requires Full Synthetic 15W-50 oil. Mobile One is specifically recomended by the Manufacturer. I find the price and availability at Walmart to be the best anywhere, it is not an easy product to find in this weight.
