Best oil I've ever used in any tractor! Literally cleans the engine and you can go more miles in between changing oil than with other brands. All my tractors are diesel, would highly recommend!

Great product except the shipping

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

Best price around, use Mobil one in all my vehicles

I have used Delvac exclusively in my DD15 for its entire life. 888,000 miles and counting. With NO rebuild! Changed at 25k give or take with 1 gallon of Lucas also included. Never had a bad oil sample report.

Very good oil. Have been using for quite some time with good results.

Hard to find item at a reasonable price but Wal*Mart had it.

I own a mobile diesel repair shop and this is buy far the best oil for the money i cant touch oil of this quality for cheaper then this

The price was amazing

Very competitive price excellent oil
