Great Product
I have been using Castrol GTX since 1976. I had been using another oil before then and after having to tear down an engine I could not believe the build up on the engine parts. The engine had less then 80,000 miles on it. Now I have had several vehicles that have gotten over 200,000 miles on them with no oil related problems. I will continue to use this oil.

Good oil but Castrol owned by BP now.
I like this oil in my Kaw KLR 650. Quieted the shifts down, seems to run fine. We'll see how the mileage changes, if any. Only downside is the BP ownership of the Castrol brand. After the crap they did to the Gulf Coast, don't know that I'll buy it again. Wanted Rotella but Walmart is discontinuing the 20w50 for some reason it appears.

    Disappointed
    I give PRODUCT 5 stars plus !!! I give Walmart 1 on handling transaction. I ordered oil. 5 quarts $12.94 a 5gallon jug. Order will take 12 days to deliver. Then I get message oil was delivered one week early, but I never received oil. They gave me a refund. I reordered oil and it arrived in two days but COST 11.00 MORE. I believe they" lost the first order " and replaced with same oil at higher price. I feel Walmart should honor Original price.

    Great oil.
    My father preferred Castrol Oil, so I have always used it when possible. I trust it.

    Bad packaging
    The product and size available is perfect and delivery time was accurate. The packaging was awful! The box was not sealed, and slightly damaged. Luckily none of the oil containers were damaged, which would have been a big mess. Also left very visible.

    The Best
    The best conventional motor oil on the market. I've been using it for 40 years with never a oil related problem.

    Dinosaurs, they died for our lubrications.
    I've used Castrol oil for decades. I have no reservations. In years past, I used Castrol 10-40w in Ford 15 passenger vans traveling 500 miles per day, 7 days per week. At 15,000 miles per month with paying passengers, I had to be sure I was doing the best I could. I would replace the vans at 2 year intervals with 360,000 miles on them. I never had a problem finding a buyer for these vans and many sold without any advertising.
