Delo 400 XLE Heavy Duty Synblend Diesel Engine Oil 15W-40, 1 Gallon, Pack of 1

I would like to thank the dinosaurs for their contribution, although at the depth that oil is located, the story does not jive. Used in 6.5 GM Diesel.

Worked well with my vintage 1980s tractor. Would recommend and use again!

Cheaper than rotella straight dinosaur oil and hasn't blown up yet.

I was Not a big fan on this oil brand. The price at the time was cheap. I will say it’s a good oil. I like motor craft but would use this oil.

Worked for several shops for 40 years. We all use Dello 400. Can't think of any issues we had with oil. I use it in my diesel pusher $$$ 🙂😴 Signed retired commercial truck mechanic.
