After calling back the military testing facility in Manching, bavaria I got some interesting news.
-It doesn't matter what kind of Diesel engine 2-stroke oil is added. It is designed as an lubrication and cleaning aid. It burns itself cleaner than Diesel.
-recommended mixture is 1:200 down to 1:250. A higher mixture will devlop blue smoke again.
- Use of 2-stroke oil is demanded, when not knowing the source of Diesel or assuming impurities or dilluted Diesel.
This is what every 2 stroke oil manufacturer claims:
Think about it!
- Outstanding wear protection
Extended life for critical engine parts
- Enhanced frictional properties
Improved fuel economy
- Excellent thermal and oxidation stability
Exceptional engine cleaning power resulting in extended valve life, reduced ring sticking, piston tightening and elimination of pre-ignition problems
- Excellent corrosion protection properties
Longest engine life
- Eliminates pre-ignition
Maximises fuel efficiency and extends piston life
- Smoke-free exhaust
Cleaner environment
Why should a mixture of 1:50 in a gasoline engine be worse than a mixture of 1:200 in a Diesel just beeing needed as a lubing aid?
Being at the official demanded saftey inspection caused the safety officer to shook his head and to run the test twice. Emissions are 57% better than the last time. The ten year old engine is now as good as a modern engine equipped with a DPF.
This shows again that 2-stroke oil is so bad for the engine...

I own an outdoor power equipment store and we service all 2-cycle equipment with Opti-2 mixed @ 100:1 w/BP octane. This mixture is ok in a new Stihl chain saw right out of the box so a 150:1 ratio should be fine for diesel engines. I use that ratio in my '05 6.0.

I'm not smart enough to know good or bad on this stuff but in the interest of equal air time here is a thread talking about the bad points of 2 Cycle. https://www.dieselbombers.com/schaef...th-legend.html

Just read that thread.
Would you trust your own high tech lab, your own emission read out test sheet or a company, trying to sell their own stuff and not showing any test results of a destroyed injection pump or injector, damaged or worn by the use of 1:200 2-stroke oil?
The "non public" test results, due to being a military installation, showing under tribologic aspects a huge decreased wear on internal moving and non moving pump parts.
Thats what it was tested for- nothing else( e.g. aspects of fuel saving, decreased engine noise)!

I've been researching this right along for a year now! Everytime someone proves something to me I WILL go research it and be sure they are right. But lot of times I'm still on the ball...
Thanks for the comment!
Sulfur is added to keep a lubricant from breaking down under extreme pressures... What do you call the IP pumps then? Your pumping the diesel fuel to pressures well above 4,000 PSI. I call that extreme pressure don't you???

Sulphur is the lubricant. Sulphur was added to be a lubricant but mostly to DISPERSE THE WATER in FUEL. It collects the water on a molecular level and splits it into burnable deposits. Look it up. Learned this with microscopic slides at a powerservice seminar.

2 stroke oil = waste of money in a vehicle. I sure love everyones opinions though...
