RED LINE High Performance Synthetic MT-85 75W85 GL-4 Gear Oil

RED LINE MT-85 HIGH-PERFORMANCE GEAR OIL is a fully synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting. This fluid is less slippery for improved synchroniser coefficient of friction and offers stronger film strength for better wear protection.
  • Recommended for Nissan 350Z and 370Z (also most Maxima, Altima and Sentra), Mitsubishi Evolution, Hyundai, Kia and Quaife synchro manual trans applications
  • Many NV4500 truck transmission applications like Chevy Silverado and Dodge Ram, for Chrysler spec MS9070
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • Offers quicker shifts, perfect synchroniser coefficient of friction
  • Eliminates notchy shifting, even when cold
  • High performance gear protection and longer synchro life
  • Recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are
  • specified
  • Satisfies the gear oil viscosity requirements of 75W, 80W, 85W and motor oil viscosities of SAE 30 and 5W30

  • Appropriate coefficient of friction for most manual transmission synchronisers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • Red Line offers lubricants to pinpoint nearly every transmission application
  • MT-LV, MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
  • Excellent for high- and low-mile transmissions
  • Compatible with petroleum and other synthetics

                          SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
                          We've tried to keep all other shipping costs as low as we can.

                          Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

                          • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
                          • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
                          • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
