This oil is excellent to have as back up. I use it for my two trucks. It is good and cheap. It is a great way to save. Specially when you buy it online and get it right on your door entrance !

Very good delivery and price form Walmart. Exceptional performance with this product for 73,000 miles on my 2015 Ford F250 6.7l diesel.

I am pleased with the purchase, however the shipping was horrible. I have three gallons out of twelve arrived busted.

Good oil and better buy then Delo. I normally like 10w30 but use this 15w40 and ad one bottle of Marvil Mystery oil.

This is a quality oil, but it is not a synthetic blend. It is a conventional oil despite what the description says.

Can’t go wrong with Mobil products. Use the engine oil on my diesel truck and also use the 0-20 on my Honda Sedan.

Works a little better than Rotella...a synthetic blend would be great. I change this out once it goes over 8000 miles.

2002 ford taurus, 6 cl, engine runs good,mobil 15 - 40 helps the car runs better,engine last longer, is old car and mobil oil os good for the engine.

Good price, easy delivery

seems to do what its intended to.
