ValvolinePremium Blue SAE 15W-40 Diesel Engine Oil 1 GA, Case of 3

I don't know how I managed to get a box of 3 for 24.99 but it is way worth it at that. So far no issues on my 2005 5.9 cummins.

Came on time

Mfg recommended, so I installed it and is running quite and smooth to Gulfport MS and back to Dallas TXAbout to complete an R/R and make another trip to Branson.I would highly recommend!

Great product and I will continue to purchase it

I use this in my truck and my backhoe, great oil. Never had any issue.

I gave 5 stars for value for money, but that's because I bought the 3 pack before the price went up. I wouldn't buy it now that the price increased. It's good oil, but the Chevron Delo I had in my VW 4 banger before this oil lasted longer. This may have been because I had some Mystery Oil mixed in ? At any rate I'm using this stuff up but won't buy again there's better out there for this price point. Got a deal on Shell Rotella full synthetic Diesel oil, I'll try that next and see how it stacks up.
