Motorhome uses 4 1/2 gallons so this saves me a pile of money on okl changes.

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.

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

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!
