Description

Maxima Racing Oil Premium 5W-16 Break-In Oil – High Zinc Formula for Maximum Protection


Maxima Racing Oil 5W-16 Break-In Oil is our top choice for breaking in new or rebuilt 4-stroke engines, especially in performance mini bikes, go-karts, race engines, and crate motors.


This mineral-based formula is engineered for high-load applications where flat tappet camshafts or roller valvetrains require maximum protection. The high-ZDDP (zinc and phosphorus) additive package delivers superior anti-wear performance during the critical first startup. It's 2X Zinc technology activates at low temperatures, providing immediate and lasting protection for cams, lifters, and piston rings.

Backed by dyno testing, Maxima’s proprietary formula promotes fast and effective ring sealing, improving break-in efficiency and reducing engine wear from the very first day.

Key Features:

  • Specifically formulated for engine break-in in all 4-stroke applications
  • Compatible with race engines, OEM rebuilds, mini bikes, go-karts, and crate motors
  • Fast ring seal for improved performance and reduced oil consumption
  • High ZDDP content protects flat tappet and roller camshafts
  • 2X Zinc system delivers rapid wear protection at startup
  • Dyno-tested for superior break-in results
  • Ideal viscosity (5W-16) for optimal flow during cold starts


Recommended For:

  • Predator 212, Tillotson, and GX200-based engines
  • Karting, mini bike, and small engine racing applications
  • All performance engines require high-zinc break-in oil


Pro Tip: Always break in your engine under load using a proper procedure. Avoid synthetic oil until after the rings are fully seated.

FAQ

What is Maxima 5W-16 Break-In Oil used for?

Maxima 5W-16 Break-In Oil is specially designed for breaking in new or rebuilt 4-stroke engines. It's ideal for performance mini bikes, go-karts, crate motors, and racing engines—especially those with flat tappet or roller camshafts.


Why does this oil contain high ZDDP?

High ZDDP (zinc and phosphorus) is crucial for protecting engine parts during initial break-in. It prevents premature wear of flat tappet cams, lifters, and other high-stress components before the engine is fully lubricated and parts are seated.


Can I use this oil for normal engine operation?

No. This oil is designed for break-in only. After 20–30 minutes of operation or one race session, it should be drained and replaced with a high-quality full synthetic or standard performance oil.


Is Maxima 5W-16 Break-In Oil compatible with Predator 212 or GX200 engines?

Yes! This oil is an excellent choice for breaking in small engines like the Predator 212, Tillotson, and GX200 clones commonly used in mini bikes and go-karts. It ensures proper ring seating and protects the valve train under load.


How long should I use break-in oil before changing it?

We recommend changing the break-in oil after 20–30 minutes of varied-load operation or after your first dyno session or race practice. This flushes out metal particles and debris from the seating process.


Is this oil safe for engines with roller cams?

Yes. Maxima’s formulation offers full protection for both flat tappet and roller cam engines. Its 2X Zinc system activates quickly, providing wear resistance at both low and high temps.


Does Maxima Break-In Oil increase performance?

While break-in oil isn’t about peak horsepower, Maxima’s dyno-tested formula helps achieve better ring seal and reduce wear, which contributes to stronger performance, better compression, and longer engine life over time.
