I grew up farming, ranching and Rodeoing
. Then joined the Army after two years of college as an 11B Infantryman. After several years I got banged up and had to get out. I now work for the Department of Defense as an Antiterrorism program manager.
Anyhow, I have always driven larger vehicles due to necessity so I have always been looking for was to save on fuel. I have tried a lot of different potions gizmo and gimmicks. Most of which didn’t work or had little effect. On my current vehicle, a GMC Denali XL I have installed a K&N air flow system and put a tornado in the air intake tube. I also run AMSOIL and a pure power oil filter. All this got me about a 2 MPG increase.
Tired of paying out the kazoo for gas my father, who is a chemist and I started looking for ways to get better MPG. Dad figured out that adding about 10% Diesel will get us better MPG. I say about 10% because you will need to play with it a bit to get the best MPG for your vehicle. For what ever reason this process varies from vehicle to vehicle. This increases the MPG because diesel typically releases about 38.6 MJ/l (138,700 BTU/US gal), whereas gasoline releases 34.9 MJ/l (125,000 BTU/US gal), 10% less (
Diesel fuel - Wikipedia, the free encyclopedia) in other words diesel burns hotter than gas. Adding the 10% will not effect or damage your motor either like some potions and elixirs being sold will. I went from an average of 14 MPG to 18 MPG just by adding the diesel for the past 30K with no problem. Also, at present, Dad and I are working on patenting a Fuel additive using used oil, both motor and cooking, combined with cosmoline and a few other secret ingredients. This additive will add about 5-10% to your MPG. I will post it when the patent goes through. In the interim try adding the diesel.
