No it says to use every 3,000 miles. I add 2 bottles about twice a year.So gumout is really,an additive, you add every tankful? Maintenance dose in a bottle.?
You could if you wanted to. They don't give a ratio, but 6 oz treats up to 19 gallons. So maybe use 1.5 or 2 oz per tank for maintenance level.Well,could you use it,as maintenance doses,like you could with redline?r techron?
