Red Fox HD Oil Analysis: proof your protection is working.
Turn a small used-oil sample into a maintenance advantage. Our HD program trends wear and contamination across your trucks, RVs, and equipment so you can extend drains with confidence and catch problems before they become breakdowns.
How the Red Fox Oil Analysis program works
Built on Red Fox Racing's oil analysis methodology, tuned for heavy-duty engines, drivetrains, and hydraulics.
1
Pull a sample
Use our kit to draw a small used-oil sample from your sump, differential, or reservoir.
2
Send it in
Mail the pre-labeled sample to our partner lab in the prepaid mailer.
3
Lab analysis
Spectrometry, viscosity, TBN/TAN, fuel dilution, and contamination testing.
4
Get your report
A clear, trended report with a plain-English recommendation from our team.
What we measure
Every sample is analyzed across the properties that predict failure.
Contamination
Fuel dilution, coolant, water, soot, silica (dirt) — the causes of accelerated wear.
Fluid health
Viscosity, oxidation, and additive depletion (TBN/TAN) to right-size your drains.
