I always suggest the non conductive clear premix. Until now the best I've tried is the EK CryoFuel.
Between the one I've tried has kept is "clear" color longer than the Alphacool one for example.
For the temps, every brand with a good premix coolant is ok. Some manufacturers like Alphacool though suggest to not use the Mayhems product.
Kind of a noob question but I've bought the LT240 and i'm going to buy the Tygon R6010 hose with EK cryofuel clear.
Problem is that i don't know the quantities. 1 meter hose enough or better to order 2 meters?
How many liters of the coolant?
