I wish it were that simple! Just now I completed a five day 1200 mostly highway trip. I checked the oil level every morning with a cold engine. The first 600 miles, no oil consumption at all. The last 500-600 miles the oil dropped 1.5 quarts. These last miles were all highway miles but so were the first 500 miles. I have seen this sporadic oil drop occurring even in city driving, although in our city we really don’t have heavy stop and go traffic, mostly 40mph most of the time with very little stopping.
Thanks for your thoughts,
Vic
