a place called shafer lubricants will pull a sample of your old uil and your new kind and test it to see whats better for your application. we use ther oil in our fleet of trucks we pay 6.00 more per gallon but it was well worth the money

Schaffer has some great products but we tryed there oil in our trucks and oil consumtion increased all but one truck.Wasnt worth the cost and trouble.Out of 5 trucks with 3406e Cats and a c15 Cat we only had the one that dint puke it out.But on the other hand there grease is ABSOLUTLY second to none.And there gear oil is GREAT as well.
