I used Techron in a lawnmower that kept stalling. Pretty basic. 5 to 1 compression flathead, meaning valves in block. Worked like a charm. Does Chevron in your neck of the woods add booze? In California, when gasoline is rated "Top Tier" the refineries do not have to add booze. In states where your legislature is bought and paid for by Archer Daniels Midland, then who the hell knows.

Combustion deposits cause running problems that have a list a lot longer than simple ping or knock. After wasting my money "-ON WHAT I-" consider to be, Snake Oil, Seafoam, I won't try it again even if it was given to me. LUCAS fuel additive seemed to work somewhat (murky results) but Techron made such a difference it was laughable. I look at it this way, you don't need to mortgage your house or risk anything but the price of a Double Burger with Fries to try it.

Seafoam dissolves carbon on pistons, intake valves and intake parts like injectors. It will not dissolve that hard green looking crud that accumulates inside carb jets. For that you usually have to physically poke, clean, scrub it off.
Seafoam works for what it's made for.....dissolving carbon deposits on pistons, valves, heads, etc.
Techron works too, used to use it at the dealer as part of a 60 k service.
BG 44K works too.

Of course you may think they are all "snake oil" unless you use the product for what it can actually do. It can't magically unclog a jet that won't let any "snake oil" into in the first place.

If you have hard green crud in the jets of your carburetor, those jets are done. They've oxidized, and will never be the proper diameter to meter fuel correctly, ever again. Buy new jets, replace them, and be done with it.
