The only diesal engine I own is in our Kubota l3560.I have put in Mobil delvac 10w30 extreme synthetic.I will run that till spring then back to a synthetic 15w40 of some kind in May.

I’m back to using Mobil Delvac Super 1300 in my semi truck with a Detroit Series 60 motor. Presently I have 15W40 in the sump, but I’ll be switching over to 10W30 in a week or two. I use the 10W30 during the winter months for easier cold startups. I’ll switch back over to 15W40 in late March or early April.

On a current OCI of Delo HD30WT in my 05 6.0 and love it. Truck seems to really like it as well. Prior flavors were T5 10W30 and Motorcraft 10W30. Since using 10W30 in my 6.0 a few years ago I've learned to love it over any other weight.

I use Schaeffer Synshield syn blend 10w30 in winter and 15w40 in summer in my Detroit 60 12.7L pre-emissions. 1,046,230 miles and still going strong. Uses approximately 1 qt per 11-12,000 miles. Oil changes at around 22,000 miles... almost 50% longer than the OEM recommended drain of 15,000 miles. Standard Donaldson oil filters.

I like Rotella T6 5W-40. I've used it in most my diesel vehicles over the last 10 years or so. 04 Jetta TDI, 09 Dodge Cummins and my 04 6.0 Powerstroke. I've even used it in my Can-Am side-by-side, which isn't a diesel though. My 6.0 has some sticky injectors so I also use Archoil.

I’m using Delo 400MGX 15w40 year round, because Karachi hits 40C in the summers and doesn’t drop below 15C in the winters.

Shell Rimula R4X 15W-40 in my 1988 Escort XR3i

It's an API SL/CI-4 , ACEA E7 oil

Factory spec'd viscosity is 10W-40

I use it because the Ford CVH engine is notorious for valvetrain wear, it's a flat tappet engine where the lifters ride on top of the cam just like on a pushrod engine, but the lifters push directly on the rocker arms.

Around 1200ppm of ZDDP should keep it happy and it so far has for the past 9000 miles since i bought it.
