I much rather have bought the two 5 gallon bundle for half the price but since your app has incorrect availability I was very disappointed to be forced to settle with this more expensive option

Great Investment !

I've used Mobil Delvac 1300 since 1999.. I have had 3 big trucks with 500+ HP Detroit Engines and put over 1 million miles on them, with absolutly No Oil Fatigue Problems.. I use Mobil Delvac in every car , pickup , garden tractors and lawnmowers that i own today ! !

Reliability!!

Used this oil on Detroit Series 60 and on my Cummins. Best conversational oil I have used so far.
