Review on 🚘 Red Line MTL Manual Transmission Oil- 4 Quarts (4 Pack): Optimal Performance for Manual Transmissions by Louis Mechtak

I love this 75w80 GL-4 MTF from Redline. Works better in my Honda/Acura than the Torco MTF. The Torco Fluid is really good (I think better) but I picked up the vibrations in 2nd gear, maybe it was too smooth for the diff or other MT components. This Redline 75w80 GL-4 MTF oil is lower viscosity than Torco and appears to be quite comparable (viscosity only) to Honda's HG MTF oil which sounded terrible in my car and wasn't very smooth. My service manual originally recommended a 10w-30 MT motor oil, but then Honda came out with an MTF HG oil which I tried and immediately replaced. This Redline is really good and belongs to the high quality category of Torco, Motul, Mobile One, Amsoil. That's really good, but there are usually certain lubricants that are better for your car or motorcycle than others. You just have to try them and unfortunately it can get pretty pricey as this gallon option was basically $15.60 per quart. Do your research and narrow down your choices. Since the manual recommends changing the transmission oil every 30,000, such a long interval justifies the higher price per liter.
