To STP
How are you guys going to address the carbon build-up on Direct Injected Engines, especially in the new Mercedes 3.5L for 2012? Your products will have absolutely no effect on these engines. In fact they'll be a total waste of money.
An example of a Direct Injected engine's intake valves at only 28,000 miles.
Please note the severe carbon build-up. STP products, nor anyone else's will ever clean these valves...ever!
Unlike port fuel injected engines, direct injection never touches or bathes the intake valves, thus it's impossible for your cleaners and detergents to ever clean them. Direct Injected engines deliver their fuel inside the combustion chamber.
Here's an illustration of a DI engine. Please note that the fuel injector is inside the combustion chamber. The fuel never touches the valves to clean them.
And here's an illustration of a Port Fuel Injected car (Like our current 2010-2011 GLK's) Please note that the fuel injector sprays the fuel inside the port, before the valve, thus cleaning it.)
Because DI engines deliver better fuel economy, lower emissions and more power, you'll soon be seeing this technology on every internal combustion engine made, not only on VW's, Audi's, Mercedes Benz, BMW, Toyota/Lexus, Honda/Acura, Ford etc.
So the question is, what will you do? Lie that your fuel injection cleaner will still "clean your engine's intake system"?
Sure it will help clean the injectors themselves, but injectors today are made so well they rarely, if ever, need cleaning. Most high octane gasolines of today have enough cleaners to take of them.

It is interesting to see that STP replied to your email. Well maybe not.

Or maybe it had to do with timing.
So the bottle is smaller and more concentrated! Same cleaning power though.
Its ergonomic! And a tapered neck, wonder why they didn't think of that before now?
Smaller foot print, easier to store, less plastic.
But the question still is...........well maybe they will get around to answering that sometime

Our 2009.5 - 2011 GLK's have port fuel injection and will benifit some from their products. I prefer to allow the cleaners that are already provided in the high octane fuels we buy (at high cost) do their magic. These after-market cleaners are a waste of money.
But if I had to use one, it would be Chevron/Techron FI cleaner.

2013 benz c250
Could someone provide instructions on how to remove the carbon build up from the intake valves using CRC intake cleaner? My 2013 C250 W204 has a turbo on it and I want to be able to spray the cleaner onto the throttle body, turbo blades and intake valve to remove the carbon build up. My car already has 40K miles on it and I want to address this issue before the carbon build up gets out of hand. Would like to avoid needing to remove the manifold just to get to the intake valves to clean them .I can't figure out where to spray the cleaner in, from?
There's too many hoses routed around the engine.
Any help on this, with pictures or video would be appreciated.
Thanks.

Just follow the directions on the CRC can. I used it on my M276 3.5L engine with approximately 60,000 miles on it. When I started to change my plugs and removed the intake plenum, I checked the valves and noticed the were carboned up a bit. I was unable to do the change then (needed to get a precision torque wrench) and put the intake back on. In the mean time, I did both the CRC treatment and a couple of days later, I did a treatment with Seafoam. When I went back in to change the plugs, I noticed that the worse of the carbon was gone. I’ll now probably do a treatment ever other oil change (5000 mile intervals).
If you have the 1.8t, I would also install an oil catch can.

Old question, but yes. Injecting the cleaner through the intake, either before or after the throttle body, is just about the only way to chemically clean the valves on a GDI engine. (See my post above.)

Great advice. There are a few cleaners that actually do something when introduced into the air intake manifold, the one I have always used was Sea Foam. Shame the valves do not enjoy being cleaned by the fuel flow, as then Lucas Fuel Injector cleaner would be my choice.

Sure it will help clean the injectors themselves, but injectors today are made so well they rarely, if ever, need cleaning. Most high octane gasolines of today have enough cleaners to take of them. Some auto manufactures will make mention of any additives they will endorse use in their vehicle that will not void the warranty. I could be mistaken but I never have noticed STP as being an approved additive.
