Valvoline Premium Blue One Solution SAE 15W-40 Diesel Engine Oil 1 GA

Great Product! Diesel engine runs quieter.

Great purchase and value if you have a diesel especially a Cummins. First oil change was done with Shell Rotella T6, which gave me no issues. But I don't drive my truck a lot so occasionally after sitting it would be a lil noisy on startup. With this oil my trick can sit for a month and have zero noise on startup which is great if you know anything about the noise some of these Cummins make or diesels in general. Performs great as I have no oil loss when conducting visual and mechanical checks of my truck. Like all oil changes it's pretty straight forward and easy to utilize. Definitely will purchase again when needed.

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.

I own a 2004 ford f250 6.0l diesel powerstroke and this truck has always preferred Valvoline semi synthetic or full synthetic . I haven't noticed much difference between either but Valvolineakes a quality product and compared to other oils shell rotella or even Lucas the powerstroke seems to like this brand and I have noticed since using Valvoline it quiets down the engine keeps temps lower longer and I get cleaner oil longer and with Blackstone testing noticed oil last about 7,500 -8,000 miles when using archoil oil additive and still decent enough to use at that point . I just do a yearly oil change with how much I drive this I more than enough . Will be a Valvoline oil fan for life as I'm sure it has saves me alot of wear and hassle vs if I were to use the other big names . Also great value and easy to find in stores as well .

we got 5 boxes out of 6; trying to contact seller. no response. product is good .

Great oil

This is the brand used in my 96 12valve. Seems to work well. 309k and still trudging along.

Always a good product

Before my oil was changed it was dirty. Now I change my oil, oil very clean. Truck very happy. Thanks to this very clean oil.

What else can I say. This is this only oil recommended and endorsed by Cummins for use in their engines. This is the only oil I use for my 2013 6.7 with over 350k on it. The engine still runs like a champ. Each jug comes wrapped in plastic a bag. Highly recommend.
