Yeah, after doing some reading, I found out, that the oil should not be too cool either, because sulfur and other contaminants will not burn away, and water will have an easier time staying in the engine as well, so an oil temp of 100 C is recommended as minimum. Otherwise, the oil will build up acidity and that can cause excess wear on the engine. This is where the old wisdom comes in, that I would rather buy a car with 150k motorway miles, than one with 50k city miles. It just bothers me, that after the engine refurb, and next to no consumption on the road, I am still losing a bit of oil on the track. Yes, I know, that VTEC engines do like to burn away some oil at full beans, and maybe it should be like this, but I really do have PTSD about oil consumption And this was only a tiny track, I don't know what will happen, when I take her to the Hungaroring for a few 20 minute stints in the middle of the summer.Nice updates. Oil coolers should only be necessary on boosted cars, otherwise they can keep the oil too cool.
