Very good. But, I’m curious about your theory of adding STP oil treatment (2 cans). I’m the same age as you and grew up using STP oil treatment in my first car - a very used ‘63 VW Beetle to keep it running. Loved watching Andy Granatelli marketing the stuff. But I’ve been wondering about whether it’s still useful for a modern engine. And I’m wondering if they’ve kept the same formula or updated it. I’ve got a 2005 Crossfire Limited Roadster with 70,000 miles. I’m still using just the European blend of Mobil1 0W-40.
