frequently asked questions
Q: Why should I try FIENDOIL® ?
A: FIENDOIL® is the ideal oil because it remains liquid at -65° F and will not congeal or gum. It acts deep into metal pores for long-lasting lubrication and rust prevention. The petroleum-based formula also works well as a cleaner to remove carbon fouling, rust, dirt, or other contamination. See how FIENDOIL® compares to popular brands by clicking the button below.
