Parker Racor gasoline spin-on filters with clear plastic collection bowls have helped protect engines for over 30 years. During that time, gasoline formulations changed, and Racor has changed bowl material formulations as well to stay compatible.
Gasoline with Ethanol compatibility
The most notable recent change to gasoline was the addition of 10% ethanol, or E10. Racor has performed extensive testing using the new E10 fuel and found the current bowls retained clarity and stability, after prolonged exposure. However, it was found that ethanol concentration exceeding 10% caused adverse material changes; including loss of clarity, crazing, and shrinkage, eventually causing the bowl to separate from the filter.
In addition to high ethanol concentrations, other factors such as age, temperature, ultraviolet light, and various fuel additives may negatively impact clear filter bowls.
