I am new here, but read the posts from time to time. I have a 2,300 mile trip coming up in two days and I have an issue.
I accidentally used one quart of Redline 15w40 diesel with four quarts of Redline 10w40...
I grabbed five bottles from the shelf and did not notice there was a quart of diesel mixed in until I was done and cleaning up.
Now, I have driven about 160 miles since then and now have black soot on the body where the exhaust exits the tailpipe and it was never there before.
Am I just being paranoid or should I change it out before the trip? Can I get away with it till I get to my destination and what the cause of concern be by doing so?
