ROWE HIGHTEC RACING GEAR OIL 75W-90 is a fully synthetic, high-performance multi-grade gear oil built for the rigours of motorsport. Designed and successfully tested in racing cars, it delivers consistent wear protection under maximum strain and rapid, repeated load changes. The fully synthetic formulation keeps the lubricating film intact where ordinary oils fail.

Purpose and specifications

This oil is intended for manual racing-car gearboxes that demand precise, repeatable shifting under load. The SAE 75W-90 grade balances easy cold engagement with a strong high-temperature film, making it well suited to the high gear-tooth pressures and constant load reversals seen on track. It supports both synchromesh and dog-engagement competition transmissions.

• 1L container for a complete gearbox oil change
• Smooth shifting from cold thanks to the low-temperature 75W behaviour, with a stable film up to around 150 C
• Optimum protection of gears, shafts and bearings against wear, pitting and scuffing under maximum strain
• Consistent performance through frequent, aggressive load changes for repeatable shift quality

When to use / change?

Choose this oil for manual motorsport gearboxes calling for a fully synthetic 75W-90 fluid. Under competition use, replace it more often than on the road, typically every 10,000 km or once per racing season. The operating range spans roughly -35 C to +150 C. Stored sealed in a cool, dry place, shelf life is approximately 5 years.

Frequently asked questions

Is this a GL-4 or GL-5 oil?
It is a dedicated racing gear oil. As no road API class is listed for this product, match the required performance level to your gearbox specification before use.

Will it improve shift feel?
Yes. The synthetic 75W-90 film aids smooth engagement from cold and holds up through repeated hard load changes.

Can I mix it with my current gear oil?
For best results, drain the old oil and refill completely rather than topping up with a different product.

Suitable for: manual racing-car gearboxes. Always verify the exact approval against your vehicle's owner manual before use.
