Bosch Standards
Mopar1973Man Notes: Remember the above test for 2 cycle oil was done at 200:1 Ratio. But at 128:1 ranks much lower in HFRR so it will pass both Engine Manufacture & Gov't standards at 128:1 ratio.

Diesel fuel Additive Blind Testing PDF File
This proves that all my research is on score. 2 cycle oil is a prefect fuel lubricant and WILL reduce the HFRR of fuel below that of all common additives on the market.
Update - January 3, 2009
Here is Bosch testing of fuel...
Bosch Testing of Fuels on VE, VP44, and CR Fuel Systems
Now US ULSD is at a 520 HFRR score. Untreated diesel fuel could score above 600 HFRR
Bosch VP44 injection pump with a passing grade at 400 HFRR. I'm fairly sure that 128:1 ratio of 2 cycle oil exceeds the 400 HFRR score.
Now US ULSD is at a 520 HFRR score. Untreated diesel fuel could score above 600 HFRR
Now Common Rail Engines passing grade at 460 HFRR now a 200:1 ratio of 2 cycle oil is very close to this score.
