Red Line Transmission Lubricants are designed to provide excellent low temperature shiftability and improved gear protection at higher temperatures. Efficiency improvements between 1 to 5 Percent are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line transmission oils to carry higher loads compared to petroleum lubricants. The stability of these products allow them to be used for extended periods. MTL® can be used in most manual transmissions and transaxles for both street and racing use unless the manufacturer requires the additional protection of an SAE 90 or the extreme pressure protection of a GL5. In those situations the MT 90 (GL4) or 75W90NS (GL5) will provide good shiftability and synchro compatibility and extra gear protection. Limited slip transaxles may require the 75W90 Gear Oil to prevent limited slip chatter. 75W140NS is designed to help reduce the noise in noisy transmissions and transaxles, while still allowing good low temperature shiftability. D4 Automatic Transmission Fluid and High Temperature Automatic Transmission Fluid provides the gear protection of a GL4 gear oil in an automatic transmission fluid, which is far superior to a conventional Automatic Transmission Fluid. This gear protection makes it perfect for lubricating automatic transaxles and high performance automatic transmissions. The D4 Automatic Transmission Fluid provides the best low temperature shiftability. MTL® provides better wear protection in most manual transmissions which call for an Automatic Transmission Fluid which can be very important in racing applications. MTL® provides the low temperature properties equivalent to a petroleum Automatic Transmission Fluid. All Red Line transmission lubricants provide excellent synchronizer compatibility.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

No more painful cracked heels! These really do work!
Material Type: Black - 3 Pairs, Size: X-Large
These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.
