Pretty much all of the old timers, you and me, we just aren't there yet
, just kidding, I qualify for old timerhood, I just don't know or remember much, where am I, oh, right, the old timers say:
Only straight wt CF-2 in the 2-stroke diesels. Premature engine failure may result, or at the least ridicule for using the 'wrong oil'! The DD Manual states multi-grade oils should only be used as a last resort. Perhaps Oil technology has advanced, but the statement that multi-grades do not compare, and shortened engine life by fleet owner reports cause me to look for a good straight wt...There was a ferry line that did a semi-scientific study re low sulfur fuel and low ash oil. They found the low ash straight wts to be best, as I recall...
The issue with the right oil in severe duty 2-strokes is the deposits that occur with too high of an ash content and additives to the oil in some multi-grades.
The following site has some info that has an old timer's advice where he found Delo 400 to be out of Spec.

In our frozen parts of the world, you might like the part about carrying bleach: You can use the bleach to pour around the tires and make a short trail in the ice and snow to get traction if it gets too slippery to untrack the vehicle
So, would I get a st wt? yep. Just so my Widow can sell my stuff without some jerk telling her I used the wrong oil in my rigs. Otherwise, it might destroy her whole concept of me as a man where at least she thought I was handy.
Come on by! What do you run in the Shelby? What kind of Shelby? LIke a MK?
