My current setup has maybe 1/5th of it as antifreeze and theres about gallon & a 1/4th in it. could it be hurting the proformance? any suggestions on a solution to use would be great.
Antifreeze works fine as an additive. Never had a problem with it. I usually use 90 parts water and 10 parts antifreeze. If you're worried about your temps just drain it and refill with less antifreeze.
