I bought 20 gallons of this oil--enough to change the oil twice in my Peterbilt with a 3406 Cat engine. Super price and free shipping. Thanks for saving me substantial dollars!

Hello, I asked for 12 gallons of oil but they only brought me 11 and I would like all the gallons to appear in the photo they take because if they take it in the car they cannot be counted and there is no proof that they sent me the amount I asked for.

This motor oil is a synthetic blend. It tolerates heat longer than regular dinosaur motor oil and doesn't breakdown nearly as quickly as regular motor oil does. In other words, this oil protects my motor better than regular motor oil does and it does this for a longer period of time.

I have used Mobil and Chevron and Texaco brands my entire life and at the time of purchase Mobil was the cheapest Walmart had, even cheaper than the store brand, so I bought it. A few bucks less makes a bigger difference when you have to buy 4 gallons for every oil change.

I love this oil I’ve used it in my gasoline trucks for a while now it works great and I’ve never had a problem most people think that because it says Fidel you can’t use it but that’s very wrong IT’s never been a problem for me and I will continue to use it in any of my vehicles

We have a fleet of six offshore charter fishing boats, all with Caterpillar diesels. This oil is recommended by the Cat dealer as the oil to use if you want to keep up with the specs in your warranty Lots of years with NO trouble. The only motor oil We use

[This review was collected as part of a promotion.] I do believe Mobil has a very good product and good reputation as for as oils go. I used Mobil oil in an industrial setting at work and have had very good results with them. As far as price Walmart has the best price on oils in my area, so I buy all my oils there.

[This review was collected as part of a promotion.] You had all the different weights of oil I was looking for and also different types I'm going to try them out in my car that I have I haven't told Toyota sienna I bought from a customer $325,000 miles and it uses oil so I'm going to try the thicker oil and see if it slows down the oil it runs great but it burns a little oil and I'm putting thicker oil and I think it'll slow it down

I purchased a new truck a few years ago with a cummins X-15.It started using oil,the more miles i put on it the more oil it used,So I changed to delvac.The first oil change it used 1/2the oil it was using.The second oil change it almost quit using oil. Amazing oil.would recomend.
