Navigating the road to reliable fuels.
Precision in Every Drop
We go beyond the standard with full-slate testing for formal ASTM D4814 certification, ensuring your fuel meets the highest standards for performance and longevity. Elevate your fuel confidence with our comprehensive gasoline testing, ensuring precision across the spectrum of liquid automotive fuels, from volatility to octane rating. Our extensive gasoline testing services cater to a diverse range of clients, including refineries, pipelines, trucking companies, gas stations, car dealerships, insurance companies, and individual vehicle owners.
About our gasoline testing services:
The ASTM specification that covers the requirements of liquid automotive fuels for ground vehicles equipped with spark-ignition engines is ASTM D4814.
We are equipped to run all tests related to this method, including measuring gasoline octane using CRF engines. This specification describes various characteristics of automotive fuels for use over a wide range of operating conditions. It provides for a variation of the volatility of automotive fuel in accordance with seasonal climatic changes in the area where the fuel is used.
While we can perform the full slate of testing for formal ASTM D4814 certification, we work with all of our customers to choose the appropriate scope of testing that best meet their needs.
Gasoline is a blend of volatile liquids, so it will break down over time. Oxidation, or the reaction of the liquid with oxygen, can lead to the formation of solid contaminants. Evaporation can leave a sticky residue, known as “gum” or non-volatile residue. These can cause clogged fuel filters and fuel injectors and can damage fuel pumps and carburetors. Ethanol (alcohol) is commonly blended with gasoline. Gasoline-ethanol blends are particularly likely to absorb moisture and can separate into two phases (a hydrocarbon phase floating on top of a water-alcohol phase, similar to the separation of oil and water). Phase separated gasoline is unusable because the water/alcohol layer will plug filters, cause corrosion and damage engine components and the gasoline layer doesn’t meet octane specifications.
The following is a list of the common gasoline tests we run. If you don’t see a test that you’re interested in, please contact us. We are always adding capabilities, willing to set up new methods, and have a large network of labs to collaborate with.
