No Fuel can guarantee to pass testing.

Ive heard of some major commercial brands coming in at 17 and 18 % Now wether thats the tester not doing the test properly or the fuel going over thats another story. probably 5 out of 10 float tests
are done incorrectly, half the time testers dont carry a thermometer, this means the fuel cannot be tested properly. just using a float is not accurate enough. The fuel needs to be at 68 Deg F or 20 Deg C in order for the float to be accurate, if it is differing in temps the tester then has to calculate using a
Baume formula to which the marking level is compensated to float.
In all fairness the fuel should be tested before quals, its been known to happen people run one fuel for quals and another for racing.

Our specific gravities are balanced to equate to 0 , meaning the extra specific gravity in Nitro is compensated by the lower specific gravity of the oils we use, these are calculated to work in volume measurements and cross refrenced .

the recommendation is exactly that, a recommendation. 20% is generally a good content to run, there is no refrence to run 20% nitro in a sanctioned event where 16% is the max allowable. But i am thankful for your concern, rest assured we do everything possible to make fuel accurately.


Hope this clears up any confusion for you...
