i use dual 1/2 (0.5) micro filters in series and have a 60 plate heat exchanger in my car. Heats the oil up too much and it weeps out of the injection pump connections to the hardlines :/

so i run without the heat eachaner turned on and i have no issues what so ever with staring or running and get about 500-1500km out of a filter. temperature about 20-25 degrees Celcius
