KCK RE15 — Performance 25W-60 Engine Oil Maximum Protection for High-RPM, High-Horsepower Applications Part Number: RE15Category: Performance Engine OilsFormulation: Group II MineralViscosity: SAE 25W-60Application: Drag Racing, Speedway, Race Boats, Muscle Cars, LS Engines, Blown Street Rods Why Builders & Racers Trust KCK RE15 Unrivaled Zinc Protection – 2200 ppmMassive zinc load shields lifters, cams, and pushrods from flat-tappet destruction and high-ramp profile abuse. Pushrod Power & Valvetrain DefenseEngineered for high-lift camshafts, solid rollers, and aggressive spring pressure in old-school V8s and new-school LS builds alike. Horsepower You Can FeelReduces internal friction, improves ring seal, and supports power output — especially under WOT. Multi-Fuel CompatibleFormulated to perform across Unleaded, Diesel, LPG, LRP, CNG, Methanol, Ethanol and E85 — without fuel dilution compromise. Extreme Viscosity ControlHigh-shear 25W-60 profile stays stable at temp — ideal for long burnouts, sustained full-throttle, and hot-lap punishment. Built for Wet Sump WarriorsPerfect for supercharged, carb-fed or injected race engines with wet sumps — from drag to endurance formats. Engineered for Heat, Horsepower & Hard Launches KCK RE15 is built for the kind of engines that live wide open — drag strip icons, street monsters, high-rpm boats, and race-tuned V8s. Its Group II mineral base is fortified through KCK’s hot blend process, delivering thermally stable, long-lasting protection that doesn’t thin, shear, or sludge. With 2200 ppm of zinc, this oil is made to protect aggressive valvetrain geometry, older flat tappet setups, and modern pushrod LS platforms where valvetrain loads and RPMs are through the roof. It clings to internals during high heat cycles, keeps pressure stable, and resists oxidative breakdown when you’re pushing lap after lap or pass after pass. Ideal For: High-RPM pushrod V8s (Chevy, Ford, Mopar, LS, etc.) Supercharged wet-sump engines Speedway & dirt track machines Big-block powered muscle cars Race boats & marine drag builds Street rods and strip-only weapons Methanol, E85 & multi-fuel race setups Technical Highlights: Base Oil: Group II Mineral Zinc Content: ~2200 ppm Viscosity: SAE 25W-60 Viscosity Index: High — stable across heat cycles Oxidation Control: Excellent resistance to oil thickening Clean Burn: Prevents deposits, varnish & build-up Fuel Compatibility: Unleaded, Diesel, LPG, LRP, CNG, Ethanol, Methanol, E85 Meets or Exceeds: API SN ACEA A3/B4 SAE 25W-60 Surpasses typical race and performance oil standards globally The High-Load Champion for Pushrod Performance KCK RE15 Performance 25W-60 is a Group II mineral-based powerhouse, purpose-built for engines operating in extreme environments. Whether you’re revving to the limit on the drag strip, hammering down the straight at speedway, or cruising in a big block beast, this oil provides unmatched film strength and wear protection where others give up. With 2200 ppm of Zinc, it defends against metal-on-metal contact in high-lift camshaft applications, especially in older or heavily modified valvetrain designs. The ultra-high viscosity supports strong oil pressure and thermal control in long-duration WOT pulls and high-load acceleration. 🦘 Proudly Australian Made & OwnedTuned for Aussie power, trusted by workshops, and pushed by racers. Hot blended. High zinc. All guts. No compromise. 5L (Also available in 20L, 205L, 1000L) Part No. RE15
