- Fuel economy will immediately increase upon initial use and continue to increase until it levels off. This happens in large percentage of vehicles. XFT immediately improves the quality and burn rate of the fuel. Also, the improvements in engine function, cleanliness, and lubrication add to the overall increase in fuel efficiency.
- You will see no noticeable change during the first few treatments, and then fuel economy will slowly, steadily increase until it levels off. This lack of initial performance can be due to a number of factors including: The initial engine cleaning process, horsepower usage, driving pattern changes, weather conditions, loads, factory fuel blends, air-conditioning, etc.
- Fuel economy will decrease for the first tank or two, then steadily increase over time until it levels off. Occasionally this will happen and is due to the initial cleaning process in dirty engines. Also, some vehicle’s computers take time to adjust to the better flow of fuel and improved economy.
- Fuel economy will go up immediately, drop for a tank or two, and then steadily increase over time until it levels off. Your vehicle takes immediate advantage of the better burning fuel. Then, as XFT works to clean the sludge and carbon build-up out of the engine, your fuel economy can decrease during the initial cleaning process.
Xtreme Fuel Treatment (XFT) is based on a chemistry that happens when added to the fuel. This chemistry happens every time. It is working all the time. XFT is not selective about when it works. It always improves the burn rate of the fuel. It always helps clean and lubricate engines, etc. The differing initial results are determined from the differing conditions of the engine, and other outside factors as stated above. True calculating tests are done with the same vehicle, with the same driver, on the same routes, with the same load, with the same fuel. There are multiple tests like this available. The bottom line – XFT will always increase fuel economy, prolong the life of your engine, decrease emissions, and increase horse power.
Items to be aware of when comparing fuel economy:
Different drivers usually obtain different results
MPG may vary due to terrain, loads and weather conditions
MPG may vary between fuel brands
MPG may vary when using winter blend vs. summer blend fuels
City mileage and highway mileage will differ – compare similar trips
For the most accurate results, calculate MPG manually
