1st I would like to say that i love the web site and have caught the craze for running 2 cycle oil in diesel fuel. I have a 03 dodge cummins that I bought 11 months ago with 66,000 miles on it and and today i have 106,000 on it . I got into useing 2 cycle oil in the fuel roughly 6 tanks ago maby a little more and have had good results, The bigest thing i notice is that it runs quieter but allso too my MPG has gone up. When i fill up on empty it takes 30 gallons so I guess i have a 34 gallon tank, to that 34 gallons i have been puting 2 quarts of Amsoil HP Injector 2 cycle oil http://www.amsoil.com/storefront/hpi.aspx . Im not an expert on fiquing the ratios so i looked up a 2 cycle oil ratio calculator on line and it tells me that to 34 gallons of fuel adding 64 oz. of oil gives me a 68:1 ratio. Thats probly alot, haha... :confused: I know most of yall recomend one ounce to a gallon with dyno and even less with synthetic, but price set aside im not really worried about the cost effectiveness of it i just want to know if i am doing my truck any good by running a thicker mix. Ive read that cummins says up to 5% is okay witch if my math serves me correctly would be 1.7 gallons of oil to a tank. .. If anyone could give me info on this i would much apreciate it! What are the pros and cons to running a heaver or lighter mix? Many Thanks - Caleb :cheers

That why the limitiation was setup. Because once you go to far the burn characteristic change considerably. Hence a change in power and MPG. I've got some people using 2 cycle oil to add lubricity back to fuels like JET-A and others that need it and they are between 1/2 gallon to 1 gallon of 2 cycle oil per tank. But since in there case they are getting the fuel for cheap rate it offset the cost of 2 cycle oil. As for myself I spend $64 bucks a year on 2 cycle oil for 20K miles basically. (128:1 Ratio) ;)
