Best for: High-revving engines, track days, competition builds — including rotary-adjacent platforms and inline-4 builds like the Miata.
Built specifically for racing use, the Dominator 10W-30 delivers exceptional film strength at sustained high RPMs. Its low-zinc formulation is ZDDP-enhanced for flat-tappet and high-performance applications, and it resists thermal breakdown far better than conventional motor oils under repeated heat cycles. We run this in our track Miata where consistent oil pressure and engine protection during long sessions matter most.
AMSOIL Racing Lubricants — Tested on Track by Team Sakura Racing
At Team Sakura Racing, we don't guess when it comes to oil. Our builds — a Mazda Miata, Nissan Silvia, and Lexus IS300 — spend real hours at elevated RPMs, in high heat, under race conditions. We run AMSOIL across all three cars because it holds up where other oils don't. If you're pushing your car on track or building a performance street car, this is what we trust.
Best for: Modern performance engines requiring a lighter viscosity — ideal for stock or mildly built engines under race conditions.
The Dominator 5W-20 offers the same race-proven protection as its 10W-30 sibling, tuned for engines that specify a lighter viscosity at startup. It provides rapid cold-start lubrication while maintaining a durable film at operating temperature, making it a strong choice for track day drivers who want maximum protection without straying from factory viscosity recommendations.
Best for: Short-throw transmissions or any manual gearbox that takes a beating under aggressive driving — including the IS300's W58 and the Silvia's weak factory transmission or any close-ratio boxes.
Gearbox longevity under race use is underrated. The AMSOIL Synchromesh MTF is engineered specifically for manual transmissions with brass synchros — the kind found in the IS300's W58 and many Nissan platforms. It provides smooth shifts even when the gearbox is fully heat-soaked, and resists the shear and breakdown that comes from rapid sequential shifts. A bad gear oil shows up as notchy shifts and premature synchro wear. This one doesn't.
