  • Great product
Size: 5 Quart Style: Full Synthetic High Mileage Configuration: 10W-40
My husband has worked in the car industry for over 40 years. This is the only oil he will use for our cars. We keep them until they are very, very high mileage, and they have all continued to run great. The last car we sold had over 300,000 miles on it. It was still running great, but we felt like it was time to let it go to someone else. We are currently over 150,000 miles on each car and plan on keeping them for a number of years more. If you use a good product and take care of your car, it will take care of you for a long time. ... show more

Same as Walmart, but delivered to my house. It took two tries to get the 40 weight they kept sending me 20 weight. Finally got this one right and paid an extra $1 for the second bottle from Walmart instead of chancing another wrong delivery.
