I think that I will stick with MB Fuel System Cleaner (Techron). I have half a tank of techron gas right now. When I go back out, can I pick up a bottle of Techron Cleaner and fill up the vehicle, add a bottle of Cleaner and change the plugs when I get home? Will the gunk from the fuel system cleaner make it onto the plugs? I'm not sure which one to do, but I don't want to drive the car too much (needs an oil change/spark plug) to burn the tank down then burn off the gas. Does that make sense? Basically can I change spark plugs then run techron cleaner?

"Gunk" takes awhile to build up, so you should be fine provided that your trip home isn't from Key West, FL to Fairbanks, AK.

The bigger question is why your engine is getting so dirty. What are you seeing on your plugs?

Well, I mean the drive would be about 15 miles round trip. I havent pulled the plugs yet lol, the trip would be on the way to pick up the products (spark plugs, oil change, etc)

I am considering just using seafoam as the gas add on. I'll get the car up to about 1/2 a tank of gas. I can get a bottle of seafoam, then I'll clean the throttle body, then I will drive about 20 miles on the HWY, and burn the gas to see what is going on after the seafoam. Does that sound like a plan?

As mentioned in another thread, if you're using a good quality fuel with detergents, adding Seafoam to the gas tank isn't bad, just overkill.
