Doing my clutch and had a bunch of fluid come out when I removed my diffs, may as well change this since it's 90k.

https://www.redlineoil.com/mt-lv-70w75w

Or

https://www.redlineoil.com/mtl-75w80-gl-4-gear-oil

Their site also says it doesn't fit a 2011 VW GTIs cbfa or ccta with 02Q (nfc what code my 6 speed is)

Ecs is only selling mt90

The old fluid was brown, still fairly clear, probably good for another 30K miles, but Redline MTL has been so good in my previous vehicles, I wanted to get it in there now. I had a syncro go up at 105K miles on my '99 TDI Beetle with factory MT fluid, and after that $800 repair, I had the car for another 150,000 miles using MTL with no subsequent transmission repairs. I am hoping early, regular changes with MTL will avoid any and all transmission repair in this GTI.

Redline MTL is a 70W80 GL4 oil and the web site says it satisfies the gear oil viscosity requirements of 70W, 75W, 80W, and motor oil viscosities of SAE 30, 10W30, and 5W30.

In comparison to OEM MT Fluid, the viscosity index is as follows:

at 40*C, OEM is 31 cSt and MTL is 56.2
at 100*C, OEM is 6.2 cSt and MTL is 10.6

So it's a little more viscous than OEM, but not enough to be detrimental to shifting in Maryland temperatures. I can definitely tell the difference that it makes. Smooth as silk. Click in, click out.

at 40*C, OEM is 31 cSt and MTL-LV is 29.8
at 100*C, OEM is 6.2 cSt and MTL-LV is 6.5

Is MTL-LV better than oem and MTL, I know.lv is just lower viscosity

Unless you're tracking the car my recommendation is to use OEM fluid. Many people, including myself, have used redline, motul, and similar fluids with the result being a notchy, difficult to use gearbox. There are plenty of threads on this topic on this forum.


EDIT: Fill/drain plug part number is N10037105. There is not a crush washer.

I just put in the oem fluid from FCP Euro, called VW and asked which one by vin. It was the link someone gave of cheapest on here they found. Fcp local pickup, same price and can do it sooner than 50k if want for free since they warranty fluids too, crazy right.

Anyway, tomorrow I am done with the clutch, q month later on days off , with rain days, too hot days etc

Also... Fcpeuro suggest a crush washer for it, I'm returning them, there were no crush washers on it already. Just bought new drain/fill plugs, why not, cheap
