Did anybody catch the brand name of the old toothbrush he was using? Gotta’ be like Cole’s no?
Back in the day, the oil additive package that went into Havoline motor oil was head and shoulders above what went into just about anything else. This was understood in the industry, and a different company quietly bought just the additive package to use themselves. If you ever saw, or, purchased STP motor oil treatment, that is what you were buying, the straight up Havoline additive package from their motor oil, sans motor oil.
Repackaging has been a thing for a long time.
