Xam Jenny Custom Oil 📥

Air-cooled engines run much hotter than water-cooled ones. They require a very specific viscosity that doesn't evaporate (NOACK volatility) at 300°F. XAM Jenny excels here.

Diesel engines face soot loading and fuel dilution. The "Jenny" custom additive pack can be adjusted to suspend soot particles more effectively, preventing the "black sludge" that locks up turbo vanes.

Modern mass-market oil is neutered to meet emissions standards. Zinc dialkyldithiophosphate (ZDDP)—a crucial anti-wear additive for flat-tappet cams and high-lift valve trains—has been reduced by 60% in standard oils over the last two decades. XAM Jenny Custom Oil allows for high-zinc, high-phosphorus blends that protect aggressive camshafts and vintage engines without destroying catalytic converters (if you spec the correct variant). xam jenny custom oil

To understand the value of XAM Jenny, you first have to understand the flaw in standard oils.

Q: Can I mix XAM Jenny with my existing oil? A: No. Do not mix it. The custom additive package is precisely balanced. Mixing it with conventional or other synthetics will dilute the additive ratios and ruin the custom film strength. Air-cooled engines run much hotter than water-cooled ones

Q: How long does the custom batch last? A: Unlike standard oil leak-down, XAM Jenny Custom Oil is "shear stable." Recommended drain intervals are standard for your engine (3,000-5,000 miles for race, 7,500+ for street), but oil analysis often shows the oil is still protecting long after standard oil fails.

Q: Is it safe for catalytic converters? A: Only if you order the "Street" custom blend. The "Race" blend contains high ZDDP which will poison a catalytic converter over time. Be honest with XAM about your emission equipment. Diesel engines face soot loading and fuel dilution

Q: Does XAM make transmission or differential fluid? A: Yes. The "Jenny" process extends to manual transmission fluid (MTF) and gear oil for limited-slip differentials.

| Problem | Possible Cause | Fix | |-------------|-------------------|---------| | Greasy feel | Too heavy carrier oil | Add lighter oil (grapeseed, MCT) | | Rancid smell | Oxidation | Discard; add vitamin E next time | | Skin irritation | Too much essential oil | Dilute with base oil | | Separation | Oil + non-oil additive | Avoid water-based additives |
