MTL has been great with fixing frozen gears in the morning. Previously had what I think was the original gear oil, which took about 5 minutes in the morning to warm up. I haven't tried anything else in the TDI yet.Powder Hound said:I vote for Redline MTL in a gear box. If an auto-slush box, I will pray for you.
Yes mobil 1 75w90 is GL-5. It also has some spec "MT-1" for manual transmissions but I really dont think its meant for a GL-4 replacement, and I would not suggest it. Works great in RWD rear ends though!Bob_Fout said:What was their reasoning, was it GL-5?
I heard the same from Growler on another forum. How is it in cold climates?dieseldorf said:Rumor has it that the new G70 from VAG is top notch stuff!
Some claim a mix should be used ot MTL and MT90 but I disagree, MTL has worked great for me in the cold and extreme hot. I will be changing it within a year and sending it to the lab for analysis.eats1963 said:I have to agree about the MT-90. I changed mine for the first time last fall, and during this extremely cold winter, it was VERY difficult to shift until everything warmed up. I will definitely be changing my fluid again before next winter.
+1 on the Redline MTL. Fixed my 2nd gear grinding and brought the trans to like new... Stock fluid made it worse after the change...eric_x said:MTL has been great with fixing frozen gears in the morning.

__. Last summer, I had my 5th gear set switched out for a .658 ratio gear. The installer drained the VW lube and refilled with Redline. Within 4 months, it started "popping out of 5th" but it's clear (looking at the damage) that the lube had nothing to do with the failure.Revolutionary_mind said:Some claim a mix should be used ot MTL and MT90 but I disagree, MTL has worked great for me in the cold and extreme hot.

G70.. is there only 1 version? Is it synthetic?
The only problem with this is GL5 works great with new transmissions. It's complete crap transmission fluid when the transmission has too many miles on it. I was about to junk my transmission until I switched over to the Redline stuff and have gotten another 50k+ out of my transmission. The thicker fluid compensates for the worn parts, not to mention that Redline has awesome products.TooSlick said:The Amaoil GL-4 rated, 75w-90 is formulated significantly thinner that their severe gear. The GL-4 product is also non-corrosive to "yellow metals" at elevated temps & is the product to use. The 75w-90 Amsoil Severe Gear is a HD synthetic gear lube for differential use. It's excellent for heavily loaded diesel pickup axles that see heavy towing loads. But I would not use it for a manual transmission unless a GL-5 is required - something like a Subaru for example...
I've been using Amsoil since 1978 and have a fair amount of experience with their various fluids....
