OK, I was in the middle of my oil change today (just took the plug out) when I remembered, that I wanted to get a sample of the oil. Remember the thread about hot or cold oil changes? Ok, guess what? I did mine hot. Tried to put the oil plug back in and ouch! The oil was way to hot to put the plug back. I will do cold oil changes from now on. Anyway, all I could do is run in the kitchen grab a cup from the cabinet (one of the nice ones) and filled it up. The sample itself should have been alright. It was right in the middle of draining. Could minute amounts of detergent contaminate the sample? The sample should be Honda 5w30 with 2950 miles.
