In the MINI Cooper world, they use SeaFoam on the regular to try and "wash" the top of the intake valves as this direct injection engine does have the intake valves "washed" with fuel.
Folks take off one of the PCV valve hoses from the valve cover and with the car running then squirt the Seafoam into the intake manifold to try and "wash" off the intake valves. I've seen picture proof from an owner doing this every tank of gas (yeah I know seem excessive, but walnut blasting my intake valves is not fun) at keeping a cleaned intake valve relatively free.
Looking at pricing, Berryman 0116 B-12 Chemtool Carburetor/Fuel Treatment and Injector Cleaner is ~much~ cheaper than Seafoam in the spray applicator bottle.
Any thoughts of the B-12 would be too harsh with regular application? Maybe not so bad because it's getting burned up and out the exhaust immediately?
Thanks for any advice.
