Hi all, I guess this is a follow up post to my other thread about oil temperatures. As I have a Subaru DIT engine in my WRX, I'd like to know what oil temp is needed to help reduce fuel , moisture, and contaminants in motor oil
I know engines with short driving cycles can have higher levels of fuel dilution, moisture and contaminants in the oil if oil temps don't get high enough. My last car was a Honda Civic 1.5 L motor driven in winter conditions and it had poor fuel dilution issues, I could never monitor oi temps on that car. My WRX has an oil temp guage so it can be easily monitored. I tend to get oil temps around 80-90 degrees C right now on most driving cycles, that would be on a distance of 10 miles or more. Is 80-90 degrees C enough to keep oil as clean as possible on a DIT engine ?
Thanks for any replies on this.
