I don't know about he Wynn either, the Dodge dealer by me uses B&G. We do not use any kind of induction cleaning at my dealership. The only thing we ever use is a fuel system and injector cleaner. The induction cleaner is supposed to clean the TB, intake, valves and pistons of carbon build up. Does is clean - yes. Is it necessary - :dontknow: . In the 9 years I've been a tech we have never had a carbon problem on the valves or pistons. I've heard there can be issues but we've never seen any. It's not going to hurt anything if you do the induction cleaning. I probably wouldn't do it until 30-50k miles though.Stinker said:
this is just dealerships way of making money by selling "preventative maintenance". Just flush your coolant every 20k, get a brake flush every 2 years and you'd be alrightNot anymore with the long-life coolant. Car manufactures are trying make vehicles as maintenance free as possible. Even with oil changes, oil life monitors are letting people go 5-10k miles before their next oil change.FerrariTruck said:

The sooner the better, imo. I changed mine the day I drove it home. Mobil 1 10w-30. I use 6 1/2 quarts of Mobil 1 and 2 quarts of Lucas Synthetic oil stabilizer.dizzy blonde said:
When I was at the ford dealership we used B&G then switched to Wynn's.They use MOC now I think. You can do the throttle body yourself. It does get a buildup around the plates due to the pcv system being plumbed in right behind it. That injector cleaner you pour in the tanks is useless other than preventive maintenance.The kind the dealership uses is installed in a pressurized machine and the engine runs solely off of that mixture and it is Very concentrated. As far as the intake carbon removal we had problems in the late 80's with carbon on 2.3L intake valves. It would get so thick that as the fuel came in the port the carbon would absorb the fuel and and make the truck lose power just like a stopped up convertor or fuel filter. Once the carbon gets that bad none of the products will remove it. Emission systems have come a long way since then with self cleaning injectors and a lot more monitoring of convertor efficiency and evaporative emissions. I would go to the parts store,get some throttle body cleaner and do it yourself every 10,000 miles or so. Maybe do the wynn's thing every 30 or 40,000. Biggest way to tell if injectors are dirty is cold start stumble and hesitation, a dirty throttle body will cause it to idle low or stall at idle. All that info and a 1.00 will buy you a coke, or soda as you yankees call itLitemUp said:I was at the dealer today changing out my subwoofer since I had blown it a few weeks back, and saw that they offer a throttle/induction system cleaning and recomend this service after 1 year or 15,000 miles. They service rep told me that it elimenates the cabon build up in the engines throtle/induction system specifically the values which are very susceptible to carbon build up.
Has anyone tried this? Any opinion?
