Why choose Red Line?
- Ester-based formulation adheres to metal surfaces, maintaining a robust, protective film even under high-heat, high-RPM conditions.
- Outstanding shear stability preserves viscosity and film-strength over extended drain intervals.
- High Total Base Number (TBN) resists oil acidification, cutting engine wear and corrosion.
- Cleaner-running; ester chemistry helps dissolve varnish and sludge.

Why choose Red Line MT-Series?
- Ester base stocks ensure superior film strength and thermoxidative stability.
- Precisely tuned coefficient of friction for smooth, positive synchro engagement.
- Free of “sticky” high-reactivity sulfur found in many GL-5 oils that can pit brass synchronizers.
- Cold-weather fluidity delivers crisp shifts from the first mile.

Why Red Line Over OEM and Other Synthetics?
- Ester Chemistry – Polar esters bond strongly to metal, creating a tenacious film even under momentary boundary-lubrication regimes seen in synchro and spur-gear teeth.
- Thermal & Oxidative Stability – Red Line’s Group V-based oils resist viscosity breakdown, permitting longer service intervals and more consistent protection.
- Friction & Wear Control – Proprietary additive package (detergents, anti-wear agents, friction modifiers) balances shift feel, reduces gear and bearing wear, and keeps internal parts cleaner.
- Race-Proven Performance – Nearly every grassroots and pro-level Mitsubishi Evo team relies on Red Line’s gearbox and motor oils to extract maximum horsepower while safeguarding components.
- Seals and Gasket Compatibility – Formulated to be seal-friendly, minimizing leaks and eliminating harsh chemical interactions common with some aftermarket synthetics.
Switching your Evo to the table above not only meets or exceeds Mitsubishi’s factory specs but leverages Red Line’s advanced ester-based lubricants for maximum performance, longevity, and driving enjoyment.
Other Considerations & Next Steps
- Always confirm fluid levels and torque the fill/drain plugs per factory service manual.
- If your Evo has an active‐yaw (AYC) or dual‐clutch system (SST on Evo X), retain OEM ATF SP-III for the clutch bath—Red Line does not cover Mopar ATF specs.
- Consider Red Line’s high-temperature brake and clutch fluid (Dot 5.1) if you track your Evo; it pairs seamlessly with esters for a fully integrated high-performance service plan.
- Keep a maintenance log of dates, mileages, and fluid change brands to track wear trends and optimize service intervals.
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.
