Those responsible for managing + correcting the unnecessary problems use of E10 and ethanol blends of gasoline may cause.
We're proud that so many large corporations, (concerned or negatively impacted by rapid transition to E10 gas type over past decade), rely on our test kits and products to prevent and/or fix problems caused by E10 gas type.
Many thousands of large corporations and organizations have been using our products over the years, who like us, are committed to sale and use of only high quality gasoline that meets all ASTM standards and engine requirements. Assurance that gas types such as E10 fuel contains 10% maximum volume of ethanol alcohol has become challenging due to misguided policies by both our government and the booming ethanol industry.
