ran a delivery this week in rain and darkness. pushed van hard 60 to 75mph. Used half a quart oil. Before this i had never used a drop. engine is 5.8 e250 92 year. I think this half quart over 400 miles of very hard driving is a little excessive. Do i expect too much. I use tewch 2000 syn blend. The truck didnt use any at all during the first 1000 miles after oil change ;noit a drop. engine has less than 180,000 on it.
