We Don't Ask You to Trust Us. We Ask You to Verify.
SFR Corporation was founded in 1985 in Great Falls, Montana, where temperatures swing 100 degrees and equipment doesn't get second chances. Robert Sanborn built SFR to answer a question the industry wouldn't: does this actually work? A ranch was purchased specifically to test products on working equipment in real conditions — not a laboratory, but the kind of brutal daily use that separates genuine protection from marketing claims.
Every claim we make is backed by independent laboratory data from WearCheck, North America's leading oil analysis laboratory. When we say 20% wear reduction, we mean measured wear metals in your oil — not a marketing number. Our products are tested to ASTM standards — the same protocols used to certify API motor oil compatibility. These aren't internal tests. They're the industry standard.
We've served General Motors, IBM, Pillsbury, Frigidaire, and Ford. We've helped a Chevy reach 614,000 miles without a major overhaul. But we don't ask you to take our word for it. We give you a kit, a lab, and a report. Then you decide.
40 years. Independent lab verification. Montana-made. Satisfaction guaranteed.
