Red Line MT-85 75W85 GL-4 Gear Oil - Superior Performance and Protection

Discover the exceptional performance and protection of Red Line MT-85 75W85 GL-4 Gear Oil, designed for manual transmissions and transaxles. Ideal for high-performance and everyday driving.

Red Line MT-85 75W85 GL-4 Gear Oil is a high-quality synthetic lubricant designed specifically for manual transmissions and transaxles. Formulated to provide superior wear protection, improved shifting performance, and outstanding thermal stability, this gear oil is perfect for high-performance vehicles and daily drivers alike. It meets the stringent requirements of GL-4 specifications, ensuring compatibility with a wide range of vehicles.

Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection

  • Appropriate coefficient of friction for most manual transmission synchronizers (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 petroleums and other synthetics

RED LINE MT-85 HIGH-PERFORMANCE GEAR OIL is a full-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 synchronizer coefficient of friction and offers stronger film strength for better wear protection.

Really good spf
Size: 2.5 Fl Oz (Pack of 1)
I’ve been using this for a little while now and I actually really like it. It feels nice on the skin, doesn’t feel heavy, and leaves my face looking fresh and smooth. I also noticed my skin feels softer after using it consistently. Definitely something I would buy again.

Pretty lightweight
Size: 2.5 Fl Oz (Pack of 1)
Although it still leaves a little bit of a shine ( more of a dewy look), there is definitely not that much of a greasy feel which really helps me to keep being consistent with using sunscreen because my big issue with using other sunscreens is that they're too greasy feeling and not lightweight and leave too much of a shine on my already oily face.

Not for sensitive skin
Size: 2.5 Fl Oz (Pack of 1)
I have combination skin, prone to acne, and sensitive skin. Even though this is labeled as non-comedogenic and best suited for oily skin, I still experienced acne because the consistency of the sunscreen is really thick. It makes it hard to blend (really hard) and upsets my skin. It also smells a lot like alcohol, more so than most sunscreens, even those from this brand. I bet it's good for some skins but it simply wasn't for me.

Finally!
Size: 2.5 Fl Oz (Pack of 1)
I have been looking for a sunscreen that does not breaks me out or irritate my eyes and this was perfect. I wash my face in the morning and I put this sunscreen on. I don't need to use moisturizer since this is enough. It does leave my skin glowy which I like but not greasy. I notice even my dark spots are fading but because I do use this everyday. My skin is tan and it does not leave a white cast. I love it. If you have acne prone skin, oily and sensitive give this a try.
