Gear Oil

Max-Gear is an extremely tough, high-performance GL-5 gear oil designed to provide maximum protection under heavy-duty gearboxes while increasing power through the transmission. Max-Gear outperforms other GL-5 oils as it combines the highest quality synthetic oils with Synslide ™, Royal Purple's proprietary synthetic oil film that is so strong and tough it won't be squeezed out of the pressure zone. Max-Gear virtually eliminates gearbox and bearing wear even in extremely difficult "film crushing" conditions caused by very heavy loads, sudden shock loads and low revs. The slippery synthetic molecules not only reduce wear and friction, but significantly increase the fluidity and lubricity of Max-Gear at low temperatures, making it the ideal product for vehicles operating in cold climates. Max-Gear ensures better operation of the gearbox, with less noise, lower temperatures and longer times, without revisions and without corrosion, both for ferrous and non-ferrous metals.

Max ATF is a long-lasting, high-performance, multipurpose synthetic fluid for automatic transmissions. Max ATF is recommended for all automatic transmissions that require Ford Mercon or GM Dextron Type III transmission fluids. Max ATF is more stable to oxidation than many other fluids and guarantees greater resistance against failures caused by heat and loss of lubricity. Max ATF is fully compatible with other automatic transmission fluids, but for best results it is recommended that the old fluid be completely drained and refilled with Max ATF.
Performance benefits
- Reduces operating temperatures.
- Greater uniformity and precision of the change.
- Ensures clean and efficient changes.
- Increases the life of the fluid in operation.

Red Line Oil MT-90 is a 75W90 GL-4 gear oil, blended with the highest quality group 5 ester base stocks. MT-90 offers superior gear and synchro protection, balanced friction for easier shifting and reduced drag on moving parts. Ideally suited to synchromesh transmissions, Red Line’s MT-90 offers one of the highest performances of any gear oil on the market making it extremely popular.

Red Line MT-90 Gear Oil features:

- 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
- Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
- Offers quicker shifts, perfect synchronizer coefficient of friction
- Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
- High performance gear protection and longer synchro life
- Eliminates notchy shifting, even when cold
- Satisifies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 40, 10W40, and 15W40
- Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified

Red Line Oil 75W90 is a GL-5 gear oil suited to many transmissions including dog engagement and sequential transmissions, it also works very well in differentials including limited slip. 75W90 is blended with the finest ester base stocks which provide a natural multi-grade, avoiding the need for unstable thickeners and increasing the film strength and temperature stability of the oil. The use of the finest materials available allows Red Line to provide superior protection and unrivalled performance.

Red Line 75W90 Gear Oil features:

- Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks, and racing vehicles
- Contains additional friction modifiers for suitablity with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
- This product is not designed for use in most manual transmissions or tranaxles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
- Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360
