Great Price, hard to find this weight anymore
250,000 miles on a Tahoe using this and still no engine problems. It's hard to find Delo 10\30 anymore

Proven brand
I really like this for lawn equipment and older trucks. Always make sure the service requirements on the bottle match your service manual though. I use this in engined where it matched my service requirements, and I may need a 10w-30 on the thicker side of the spectrum. I have a 93 Silverado with a 5.7 and several lawn mowers than have lasted a long time on this stuff. My father in law uses the straight 30 weight of this brand and 15w-40 and had farm equipment older than me. Good brand.

great
killer oil for the price. i hate spending $20 for oil at the local auto part stores when you can buy this. and no this is not just for diesels! oil weight is oil weight. if you have the proper weight, it can go in any corresponding engine.

Best Engine oil I have found.
I use this oil now exclusively in all my gas and diesel engines. Oil consumption went down. The ratings and reputation of this oil are great. This is a proven oil from a proven manufacture. Several of my friends and my mechanic are now using this oil as well.

Best price I have found on synthetic blend heavy duty ...
Best price I have found on synthetic blend heavy duty diesel oil. Did come in the older blue bottle, but it is the same oil. My powerstroke runs better on this oil than on the conventional 15-40 Dino oils.

Nothing but the best
This is what I run in my 6.0 powerstroke, I have been for about 60k miles it's been great always passes oil analysis even with a 250k mile motor

but it doesn't keep the car running smoothly like the semi-synthetics
It'll do in a pinch, but it doesn't keep the car running smoothly like the semi-synthetics, or full synthetics I usually buy.
