HOW MUCH CAN I SPRAY ON A STOCK 2.2 ECOTEC SAFELY? (OH IT'S WET SPRAY)
I have a 75 shot with colder plugs any higher then that go with direct port
yep 75shot up here in denver colorado seems to work fine
i sprayed a 75 shot on stock plugs (not recomended) and 100 octane for 1 bottle now i have copper plugs and 93 octane
the gm performance book references 75 shot for the stock engine as well
