So, I have read that you need to get our oil temps up to 212F to burn off contaminants. My question is, how long do you need to see these temps?
The reason I ask is that during the winter, for me to get to these temps I have to drive in a lower gear and keep RPMs up. For instance, I can be on the highway for 20 miles and the temps may not go above 178 - 180 unless I'm putting some stress on the engine by going up a hill. My Subarus have a manual mode where I can go highway speeds and drop to 3rd, 4th, 5th, etc... I usually will go down to 4th at around 70MPH and I can get the temps up to 212 and sometimes closer to 217 but if I say go up to 5th gear the temps will slowly drop and if I go back to full auto, they may drop to 194 for example. Obviously, driving in a lower gear blows through gas so I was wondering how long do I need to see 212F or higher.
If this has been covered, I apologize. I didn't see it when I did a quick search.
