I've got a rebate in hand for up to $7.00 on a purchase of Valvoline MaxLife Fuel System Cleaner, SynPower Complete Fuel System Treatment or SynPower Super Concentrated Fuel Injector Cleaner.
I run Fuel Power in almost every tank in my car and when I can in the wife's Envoy (maybe once a month). The Envoy only has about 9,000 miles on it. Is the purchase/rebate process worth it for any of the above products? I am leaning towards the Complete Fue System Treatment for the Envoy, but wanted to make sure.
