is it normal for an engine to start running a little hotter with premix im only running about 1/250 beacause the omp is still hooked up, but i drive alot and its winter so i thought the extra protection wouldnt hurt, anyway its not alot hotter im just curious if this is whats causing it.

 

Nope, start checking the cooling system, now!
