Engine treatments and oil-system care for engines that work for a living.
Engine MAX™ Treatment & Oil Stabilizer
- Increases compression and fuel mileage
- Helps prevent oil breakdown
- Reduces friction wear and heat stress
PTFE friction-reducing technology that bonds to friction surfaces once heated, filling in microscopic scratches and pores. GF-7/API SQ compliant, compatible with all oils, and safe for GDI, PFI, and diesel engines.
- • Cold-start protection, extends engine life
- • Reduces wear by 50%–90% as shown by oil analysis
- • Part# T111 · 11 oz
High Mileage Treatment
- Excellent protection for high-mileage vehicles
- Reduces timing chain wear
- Helps revitalize seals and gaskets
A GF-7/API SQ compliant full-synthetic leave-in treatment engineered to restore performance, protect vital parts, and extend engine life on high-mileage vehicles. Fortifies detergents and anti-wear components without altering viscosity.
- • Compatible with all conventional and synthetic oils
- • Safe for GDI, PFI, hybrid, and diesel engines
- • Part# T1088 · 11 oz
Oil System Cleaner
- Helps lubricate while cleaning
- Frees sticky lifters and piston rings
- Removes loose dirt and wear metal
Concentrated detergent designed to remove oil-system deposits, gums, and varnish while helping free sticky lifters and piston rings. Easy 5-minute pre-oil-change service.
- • Reduces excess oil consumption
- • Part# T108 · 8 oz
Universal Stop Leak
- Stops and prevents leaks
- Conditions seals — non-corrosive, non-clogging
- Most leaks stop within 150 miles or 3 days
A multi-purpose stop leak that can be added to ANY oil — engine, transmission, power steering, rear end. A synthetic seal conditioner that restores elasticity to seals dried out from normal wear and age.
