Re: Manual transmission hard to shift in cold weather
for really cold climates your best bet would be a 50/50 mix of Redline MT-90 and Redline MTL. This gives you a slightly thinner weight around 75w-85 or so. There are some people on bobistheoilguy forums that run this in their MS3 and say it is awesome. Or if you want you can also run straight MT-90 which is 75w-90 which is what the specs call for for our cars. I am running straight MT-90 in mine and it shifts much better in the cold than the stock fluid ever did but if you are in a really cold climate you might want to do the 50/50 mix as the thinner the fluid the better the synchros work especially in the cold.
