Huh.... I had that on my tercel back when it was going through a quart of oil each week. I figured it was a blown (or bad) headgasket and traded it in. Dealership told me to bring it back for trade before I did any engine work. At $3,500 for the car it wasn't worth putting another $1500 or more into engine work. :lol: So I never found out the real problem. I drove it at least 10 miles to work each day.
I have 26,000 miles on my truck, have done all but 1 oil change myself and never had that. :whatthe:
Then again I rarely make short trips. I have a half hour commute to and from work, and drive at least 5 miles to my inlaws. Once in a while I drive half a mile to a gas station or small grocery store, but most of the time it's at least 10-20 miles. Maybe that's why I never see it.
