During the production of our products we use only the best quality raw chemical materials with highest levels of purity. We do not use second class products or cheap alternative ingredients. The unwavering usage of raw chemical materials of the highest quality as well as precise blending and proper storage methods result in the consistent high quality of the Runner Time products which our customers demand. Our products conform to the European laws (92/32 C.E.E.) regarding chemical products and their necessary identification (EWG 88/379-67-548 ecc). Each canister is clearly marked with a productions number, an expiry date as well as chemical analysis of the constituent parts.All Runner Time fuels have been developed and tested at national and international level championships thanks to the input of many different champions in RC car, aeroplane, helicopter and boat classes.Runner Time fuels significantly simplify the process of tuning the idle and on-load fuel mixture settings of your engine. We use only the finest and purest Nitro methanol. The stated percentage of Nitro methanol on the canister is an honest and accurate as this is measured by the volume method. Other manufacturers choose to base their measurements on the relative weights of the various components within the fuel, thus saving on some of the more expensive ingredients. In fact some of the so called 10% fuels available on the market have been shown to contain less than 7.5% Nitro methanol which measured via the volume method. It is important to consider these different measuring methods when buying fuel to be certain that you get the fuel you paid for.
