I have 2 cars with GDI engines. I have been using the Seafoam upper engine cleaner to try and keep the deposits off the valves. This time on my truck I used Lucas GDI cleaner. I don't know if I like it and am leaning towards going back with the Seafoam. I didn't seem to get any smoke or anything out of the tailpipe with the Lucas but typically do with the Seafoam. Maybe that don't matter? For the truck the Lucas is definitely easier to use.
Any thoughts or experience?
