Yeah they are the same stuff. Awhile back someone sent virgin samples to the lab. I think the Truck and SUV stuff has a Boron tracer in it thats the only difference. Well other then the bottle and price!
Thats why I use it Walmart has it cheap, I am not going to order oil then with shipping its like $6-$7 a quart. 15w-50 will work just fine, and that is what I would use if Delvac 1 wasn't sold at Walmart.
