  • Develops a tough lubricating film that protects engine parts, even in high-heat, high-rpm conditions that break down other oils.
  • Contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions, guarding against compression loss for maximum power and engine life.

EXCELLENT ANTI-RUST PERFORMANCE

  • Protects engines during use and during inactivity or long-term storage.

NMMA CERTIFIED

    I've been using Amsoil as far back as 1996 in car's boat and small engine's . two and four cycle and Hell I even use it in a modified dirt car oil's lube's tranny fluid gas treatment's . and for those of us the live in sub zero climate the product's stay pliable every thing starts easier . When rebuilding the engine they are clean and cylinders still hash marks from honing yet. I'm sold , I've been wrenching for year. Keep up the good work and keep America running strong.
    Bottom Line
    Yes, I would recommend this to a friend.
