Important Factors for Accurate Mileage Testing of MPG50 & Nichels Engine Friction Treatment 

MAKE SURE YOUR VEHICLE'S AIR FILTER IS NEW & CLEAN. Combustion requires oxygen and to get maximum mileage & performance your engine needs to breathe well. To accommodate complete combustion MPG50 will need more air. Mileage and performance suffer substantially without adequate airflow, because full combustion is not possible without adequate oxygen. If you disagree, then try running a 100-yard dash without breathing and see how well your human engine performs. 

To get best mileage & performance we strongly recommend K & N air filters. Without question, they are the World's Best Air Filters - and they have a Lifetime Guarantee. See:  

Some vehicles on the road today have electronic apparatus which provides a "miles per gallon" read out.

However, we believe that the most accurate way to test miles per gallon is to write down your odometer mileage, or set your trip odometer to zero, when you fill your fuel tank and then when you next fill your fuel tank, divide the number of miles traveled by the number of gallons used.

That is: total trip miles traveled divided by gallons of fuel used = MPG. This will give you the most accurate result.

How do I measure mileage accurately to see my true savings from using MPG50?

You must first know your average baseline gas mileage without MPG50. Here s how:

    • Step 1: Fill your fuel tank on the slow setting. Let the pump run until it shuts off automatically. Get a receipt that shows the number of gallons.
    • Step 2: Sit in the driver's seat and zero out the trip odometer or copy the current mileage reading
    • Step 3: Drive your vehicle until the tank is about half full or less. Fill the tank on the slow setting until it shuts off automatically. Get a receipt that shows the number of gallons.
    • Step 4: Check your trip odometer and record (or remember) the number.

You now have two numbers: The miles traveled & the gallons of fuel used. To calculate miles per gallon divide the first number by the second.

miles traveled / gallons used = MPG (miles per gallon).

Example 1:
It took 23.7 gallons to fill your Hummer. You've driven 263.5 miles since your last fill-up. Your gas mileage is calculated using the formula
       263.5 / 23.7 = MPG (miles per gallon).
       Your result is 11.12 MPG

Example 2:
It took 12.9 gallons to fill your Honda Civic Hybrid. You've driven 551.8 miles since your last fill-up. Your gas mileage is calculated using the formula
       521.6 / 12.9 = MPG (miles per gallon).
       Your result is 40.43 MPG

Please try to keep as many factors consistent as possible, because there are numerous factors which affect your mileage, including, but not limited to:

    • The number of persons & total baggage or freight weight in your vehicle
    • Tire pressure - please use factory recommended tire pressure or slightly higher
    • Stop and go traffic conditions are hard on mileage
    • Weather conditions: cold, snow, ice, rain, strong head winds - all affect mileage
    • Engine idling time gives you zero miles per gallon
    • Open windows cause a 10% drag on fuel efficiency
    • Use of the air conditioner is a fuel efficiency drain
    • The octane rating of fuel used
    • If your fuel contains ethanol or MTBE mileage drops off due to less energy (see info below)
    • The blend of fuel used (use of the same brand provides more accurate test results)


MAKE SURE YOUR VEHICLE'S AIR FILTER IS NEW & CLEAN. To get maximum mileage and performance your engine needs to breathe well. Mileage and performance suffer substantially without adequate airflow, because good combustion is not possible without an adequate oxygen supply. If you don't think so, then try running a 100-yard dash without breathing and see how well your body performs.

To get the best mileage and performance we strongly recommend K & N air filters. Without question, they are the World's Best Air Filter.

Is There A Difference In Winter-blend And Summer-blend Gas & Does It Effect Gas Mileage?

In winter-blend fuels you get about 10% Ethanol or MTBE (Methyl Tertiary Butyl Ether) ( These blends, If you get them, have less energy per gallon of fuel and, therefore, fewer miles per gallon. They should be listed on the gas pump if you get either of them.

Winter-blend gasoline is cheaper because it does not require the costly processing which makes summer gasoline cleaner. The Environmental Protection Agency requires the removal of the volatile chemicals which evaporate in hot temperatures & mix with pollutants to create ozone in summer months, the AP reported. The blends differ by about 1 cent per gallon in price, but pump prices between the two fuel blends can vary as much as 10 to 15 cents at the pump, according to Phil Flynn, analyst for Alaron Trading Corp.

IMPORTANT SAVINGS TIPS WHEN PUMPING GAS (Here are tips to get more of your money's worth from every gallon of fuel.)

1. Only buy fuel or fill up your vehicle in the early morning or late evening when the ground temperature is cold. Keep in mind that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so when buying in the afternoon or the evening your gallon is actually less than a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays a very important role. A one degree rise in temperature is a big deal for this business & service stations in America do not have temperature compensation at the pumps.

"So what?", you ask. Well, according to a study done by the Kansas City Star, U.S. consumers paid about $2.3 billion more for gasoline & diesel fuel in 2006 than they would have had to if the pumps had been temperature compensated or if they had bought gas in the early morning. Reference: Automatic Temperature Compensation -

2. When you fill up do not squeeze the trigger of the nozzle to a fast mode. You will find that most triggers have three (3) stages: low, middle, and high. In the slow mode you will be pumping at low speed, thereby minimizing the vapors generated as you pump. All hoses at the pump have vapor returns. When you pump at the fast rate, more of the liquid going into your fuel tank becomes vapor. That vapor will be sucked up & returned to the underground storage tank, so you will get less gasoline for your money spent.

3. One of the most important tips is to fill up when your gas tank is just half full (or half empty). The reason for this is, the more gas you have in your tank, the less air occupies the empty space. Gasoline evaporates at a very rapid rate and is a direct function of the ambient temperature. Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so evaporation will be minimized. Unlike service stations, here where I work, all trucks we load are temperature compensated, so every gallon purchased is the exact amount.

Another good tip: whenever you see a bulk gasoline delivery truck pumping into the storage tanks where you stop to buy gas, DO NOT buy your fuel there. The fuel here is being stirred up as it is delivered, and you can pick up dirt, rust, scum, etc. which typically settles to the bottom of bulk fuel tanks. This debris can clog fuel filters & cause related fuel system delivery problems to your vehicle.

This info will help you get more value with less problems for your gasoline & diesel fuel dollars.
