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.

I’m happy with it
Size: L50 Hybrid-renewed, Size: L50 Hybrid-renewed
Works great.
Edit:
After a week that I wrote works great, it had the issue that when it starts cleaning it looses power and shuts off after it leave the dock. When it disengages from charging it’s dead basically so unfortunately I returned it. But I will buy it again I was happy with it.

Charging base makes awful high pitch noise.
Size: L50 Hybrid-renewed
It cleans fine but the charging base emits a terrible high pitch noise. I have to unplug it when nearby. Cats no longer want to sleep in the same room as the vacuum base. Update: A little over a year later and it appears the vacuum's onboard wifi module has passed the rainbow bridge to electric heaven. Can no longer connect the L50 to the app or local wifi. Tried resetting, reverting to older version of app, changing my wifi to 2ghz only. Trying setup in airplane mode. Nothing works.

It worked!
Set name: 10 Jumbo, Set name: 10 Jumbo
I bought this to fit a full size 4" memory foam mattress topper. I gotta say it took 3 of us. 1 to lay on the memory foam and 2 of us to get it shoved in and keep pulling the bag up. But it actually fit! My arm was dying using the hand pump so we used a vacuum. It worked better than the hand pump. Due to what I was storing it did not shrink very flat, but compared to the size of the memory foam it shrunk a lot and will definitely save space!
The bags arrived today so I dont know how well it holds up long term but the bag was very sturdy yanking it up around the foam. Didn't tear or stretch. And it actually fit!

Air comes out and STAYS out!
Set name: 10 Medium
I’ve tried so many different versions of these vacuum storage bags over the years, and this company seems to have finally figured it out. They’re absolutely not exaggerating about the 80% space savings. What really impressed me is the pump design — it actually screws onto the bag, so it stays securely attached while removing the air instead of constantly slipping off. It also has a stop valve built in, which prevents air from escaping when you remove the pump to put the cap back on. Such a smart design improvement over other brands I’ve used.
I bought the medium 10-pack to store my winter clothes in two 66-quart storage bins, and they fit surprisingly well. That said, part of me wishes I had also picked up a few of the smaller sizes just because they’d probably make stacking and organizing even easier. Overall though, I’m really impressed with the quality and design.

Great bags!
Set name: 10 Jumbo
These space bags are awesome! The company gives you a hand pump but your vacuum works great. They also give you tabs to slide over the ziplock part which works great. I bought the jumbo bags and I can’t believe what I was able to fit in them. More than one summer king size comforter in a bag, and 1 oversized extra large and thick king size winter comforter with shams and sheets in one bag. Other bags had several queen size quilts or comforters and decorative pillows. I highly recommend these bags. The price is great too.
