Seafoam through the intake really cleans stuff best. But, to clean fuel injectors, Chevron Techron Concentrate is the best IMO. Although, you can also run Seafoam through the gas tank. Now, the Lucas Oil Fuel Treatment/Top Cylinder Lube (not the Deep Clean) is good stuff to run with every fill up. Not really a cleaner, but has some detergents and lubes the tops of your piston rings. Get a gallon of it.
