Tony, I used the BLUE Startron but have used the RED Sta-Bil in the past (I hadn’t looked in marine stores for a marine version of Sta-Bil). I deliberately chose the marine product this time because of its touted superiority for long periods of vehicle disuse that is common to both marine engines and our vintage cars–except for you guys in Florida!

Let me add to my MMO content that our L-head and T-head engines are not particularly efficient and thus arguably have a greater tendency to acquire carbon deposits in the cylinder heads than OHV engines.
