Delo 400, because it is easy to find, and most truckers would recommend it.

Like the others availability and cost. As far as the oil itself goes I would be as comfortable using one as either of the others, but availability makes the difference.

Good luck,

Dumb question on my part: why Delo over Shell Rotella 15W40?

Rotella T is the same thing. Rotella has a little higher parafin content than the other three, but if you're changing it often enough this won't cause a problem.

Rotella is probably almost as easy to find as Delo, but I started wtih Delo many years ago and have stuck with it. I don't like changing oil brands. I would rather keep the engine seeing the same stuff. Just my anal retentiveness I suppose.

Have a great day,

Thanks all, I went with the Delo 400. I use Caterpillar synthetic 5w40 in my VWJetta TDI and change it every 10k miles per VW. The 300SD I will change every 3k miles.

LarryBible, thanks. daBenz used Pennzoil and Rislone until the C-rated oil became expensive and hard to find. Changed to the Rotella when the last barrel ran out, and daBenz seems to like it, as well as the road trucks. I won't willingly change brands, but price and availability won that battle. And I still use the Rislone.

Delo, preferred by more trucks and buses running Detroit, Cummins, or CATs. I'm using it in an gas W126, and loving it, it's better than what my parent's former mechanic used, Pennzoil 20W-50

Todays oils have been developed to an incredible level. A very high percentage of this development has to do with the additive package. The universal grade oils that we are talking about in this thread have evolved to an incredible level for their specific purpose, diesel engines.

This additive package is a very carefully developed BALANCE. Using any additive beyond that in the oil can disrupt this delicate balance. I believe the Rislone is a waste of money and possibly even detrimental since it disrupts this BALANCE.

Good luck,
