Ok Gang...
I'm sure a lot of your have heard about this concept and would like to get more information about it. I'm not the one that started it but a guy that's nickname is Dorkweed over on my forum started it back in 06. I'm the one that picked up the torch and continued on.
Why do we need to use it?
Because the VP44 was designed for fuel scoring <450 HFRR and today fuels range around ~520 HFRR which means there is less lubricant in the fuel. Now if the delivery truck for gets to add the lube package to the truck before delivery then the fuel can be up wards of 650 HFRR which can be quite damaging.
Bosch's fuel testing...
How much 2 cycle oil to use?
128:1 Ratio is fine for 12V and 24V Cummins trucks. On CR engines up to 07 you want to use 200:1 ratio. Beyond 07 don't use 2 cycle oil...
How about other fuel additives how did they score?
This was a independent lab that do the testing of fuel additives.
HFRR Values Of Diesel Additives
Will 2 cycle oil effect performance of the engine or MPG?
Yes... It will typically give a slight gain of 1-2 MPG and may even give about 10-20 HP gain if mixed properly. Reason why is because 2 cycle oil is a cetane reducer. So as the cetane is reduced the BTU's rise which means more work can be done in a single stoke.
ASTM testing labs grading scale for diesel fuels... Take notice as cetane rises the BTU's fall... Hence why winter fuels with high cetane give poor fuel mileage.
Will 2 cycle oil plug my injectors or fuel filters?
Simply No... I've been running 2 cycle oil for over 100K miles and absolutely no problems with filters or injectors.
Injector after 80K miles of 2 cycle oil.
Ask away gang...
