REDLINE LOOKS AFTER YOUR HIGH PERFORMANCE JAPANESE CARS

Red Line Products to Optimise the Performance of a Turbocharged Nissan Skyline

Engine Oil

Choosing the right engine oil ensures optimal lubrication, cooling, and cleanliness for your RB25DET/RB26DETT turbo motor. Full synthetic oils stand out for their thermal stability and anti-wear additives.

• Full synthetic base oils resist breakdown under high boost and temperature spikes.
• Robust detergent packages keep turbocharger bearings and pistons clean.
• Proper viscosity at operating temperature maintains oil pressure and wear protection.

Transmission Oil

Turbocharged Skylines use two main manual transmissions: the FS5R30A (5-speed) and the Getrag V160 (6-speed). Gear oils must protect synchronizers and gears under AWD loads.

• FS5R30A (5-speed) • Redline MT-90 GL-4 75W-90: safe for brass synchros, high performance protection, smooth shifts
• Getrag V160 (6-speed) • Nissan Part KLD40-00004 (or Toyota 08885-01306) ATF • Redline High Temp ATF: formulated for high-temperature stability.

Differential Oil

Skyline AWD models feature two differentials requiring GL-5 fluids, often with LSD additives:

• Front Differential (F160): Red Line GL-5 75-90
• Rear Differential (R200 LSD): Red Line for normal street use GL-5 75W-90(for heavy or track use Red Line 75W-140 or 80W-140

Popular choice: Redline 75W-90 Gear Oil with limited-slip additives for smooth lockup and long service life.

Why Use Redline Oil?

• Fully synthetic formulations for outstanding thermal and oxidative stability.
• Unique friction modifiers and PTFE-like particles reduce drag while maintaining high film strength.
• Proven in motorsports and OEM racing applications to slash transmission failure rates.
• GL-4 and ATF products engineered to protect brass synchronizers and hypoid gears.
• Broad viscosity range covers everything from cold starts to track-day heat cycles.

Beyond oil selection, remember to use high-quality filters (e.g., K&N HP-1002 or Redline filter elements), adhere to 5,000 km (3,000 mi) service intervals, and monitor oil pressure and temperature for the healthiest turbocharged Skyline drivetrain.

Protect Your Engine

Keep the fuel flowing at optimum levels by making sure the injectors remain unclogged.

Red Line SI-1 Fuel System Cleaner

Cleans injectors, carburetors, valve and combustion chamber deposits with a concentrated blend of the most powerful high-temp and low-temp detergents available

• Cleans all forms of fuel injectors, including GDI
• Enhances fuel stability; reduces gum and varnish formation
• Use one bottle per tank for most effective treatment, cleans to nearly 100% efficiency in one treatment
• On a GM 3.8 litre V6 engine the 0 to 70 KPH was increased by 21% after unequally plugged injectors were cleaned with SI-1 injector cleaner.

Keep Your Cool.

Use Red Line Water Wetter in the Radiator

One bottle of Red Line Water Wetter in the radiator will decrease the cylinder head temperature by 10 degrees C.

This reduction in temperature may allow more spark advance to increase torque.

All this while reducing rust and corrosion and cleaning and protecting water pump seals.

If your vehicle is air conditioned the cooling system requires anti-freeze use Red Line Supercool fortified with Water Wetter.
