Good price, Quality oil

My normal oil wasn't available so I bought this as a replacement. Meets all the specs for my vehicle and saved a lot by shopping at Walmart vs the auto parts stores. Nice bottle design made it easy to pour. I would use this product again.

Good Vakue

This is a good value for your money. I frequently have to purchase oil for both my mowers and several vehicles and this is one of my first choices.
