2 Cycle Oil - Fuel Additive

First and foremost... 2 Cycle Oil theory was designed for the older diesel engines in mind. The older engines deisgned for HSD and LSD.


As far as 2 cycle oil usage and information I've got a awful lot to even think about posting as a sticky so the best I can do is post link to the information and allow you guys (and gals) to read up and post question about such...

General 2 Cycle Oil Information

Dose Information
Typical usage of 2 cycle is 128:1 ratio. But some 3rd Gen Cummins tend to like a light does at 200:1 Ratio. As for Fords and Chevy's the both can use the 128:1 without much problem

Orignal test results document

Bosch Fuel Tesing

Noise Testing

MSDS Sheets of common products
Failure Facts

Some of the common reason that 2 cycle oil might not perform as you expected.
  • Under/Over Dose of 2 cycle oil
  • Not measuring proper amount of oil to fuel.
  • Mixing With Other Additives
    • Cetane Boosters
    • Injection Cleaners
    • Anti-Gels (Pour Point Depressants)
  • Overhead Computer Vs. Hand Calculation
  • Weather Changes
    • Temperatures
    • Winds (Headwind or Tailwinds)
  • Road Conditions
    • Rain Flooded, Snow packed / Slushy
  • Speedometer/Odometer Errors
  • Changes In Fuel Quality
    • Winter Fuels (High Cetane >45)
    • Summer Fuels (Low Cetane <45)
  • Changes In Operation Of The Vehicle
    • Drivers
    • Speed
    • Load weight and towing weight changes
    • In town or highway operation
