Would running a dose of Seafoam through off analysis results? Specifics: The car is a '95 Accord with V-TEC, 123,700 miles. I think it's pretty clean, but I don't really know. It's currently running M1 T&S 5W-40, and has 1300 miles left on this OCI. I'm planning on draining the oil after that, and sending a sample to Blackstone. This will be the first analysis I've done, do you think the results will be skewed by putting Seafoam through it?
