Product Information

This listing covers the exact Royal Purple gear oils configuration identified as Royal Purple Synchromax Synthetic Manual Transmission Fluid - 1 Quart.

Catalog fitment covers the listed 1987-2026 vehicle applications. Exact year and submodel combinations appear in the fitment table below; compatibility must not be inferred for every trim across the full range.

Manufacturer-supplied details include If your manual transmission's factory fluid spec calls for an ATF or another light-viscosity oil rather than a heavier gear oil, Synchromax is formulated to fill that spot; Same applies to transfer cases that spec a light-viscosity lubricant; It's also suited to 2-cycle motorcycle gearboxes that call for a light-viscosity lubricant, if that's another machine you're maintaining.

Per Royal Purple, here's what Synchromax is built for:

This isn't a bolt-on part, it's a fluid choice, and the fit that matters is between the fluid and what your transmission's factory spec calls for. Royal Purple recommends it for units that spec an ATF or other light-viscosity oil, not for a transmission built around standard gear oil, so check your spec before you pour it in.

Listed specifications include Quantity: 1 quart; Recommended for: Manual transmissions, transfer cases, and 2-cycle motorcycle gearboxes that specify an automatic transmission fluid or other light-viscosity lubricant.

Use manufacturer part number 06512 to identify this exact Royal Purple configuration. Match the full part number, vehicle application, position, dimensions, material, finish, and included components before ordering.

No Robots. Just Car People.

Buying parts for your Mustang or F-150 should not feel like homework. Too many stores bury you in a giant catalog, slap the same distributor description on every product, and leave you guessing whether it even fits.


We do it the other way. We carry the brands you already trust, we tell you what a part actually does, and we give you the truth about the tradeoffs before you spend a dollar. Drone on that exhaust. Ride quality on those springs. Whether you need a tune. The stuff the big catalogs leave out.
