"Gas Additives" Are They Needed In My 09 DFI ?
Hey Y'all, any benefit to adding "any" type of additive to a tank of gas ? Could it prolong an injector service, and do they really work .....
When I had my 4 yr service done at the dealer ( new plugs and all ) the P dealer added a "gas additive product" and I noticed the difference in response for a short while after the fact.
There's so many types out there and I was wondering if anybody uses these products.

I use BG 44K every 10-15k miles on all my cars & boat (Vortec 350/350). You can buy it on line and a few small shops carry it. Will all the discussion here on RL about the DFI engines and our 9A1, I'm not so sure it helps much since fuel is injected strait into the cylinder vs an intake chamber prior to the valves! Most certainly has to help on the exhaust side! My $.02

this is a debated issue, a lot as much as the topic of Oil, but there are a lot of opinions.
The industry is struggling w/ the issue of carbon build up in the DFI engines just ask any SA/Tech at Audi, BMW, VW, MB, Porsche.
I use Techron 2x a year, including once just prior to an oil change. I also do an Induction Service every 10-12k miles. YMMV.

sure, its simply a multi step induction / fuel system tune up. I just DIY it on my Cayenne. BG, 3m and others sell the kit for $30-50. Dealers can charge upwards of $150!
basically you spray in a solvent/ cleaner directly in the intake while the engine is running, clean the throttle plate, and pour fuel additive in the fuel tank.
takes about 20mins DIY.

All direct injection engines are going to get carbon build up and need to be cleaned out. All of them.
Car manufacturers love direct injection because it improves fuel economy numbers so they can meet CAFE standards, and since it usually takes a few years for the carbon to really start to screw things up, the car is usually out of warranty anyway.
Personally, I think DI engines are over rated. A cheap way for automakers to get high fuel numbers that results in the consumer paying $1500 or more every 40K miles to clean the crap out.
No such gunk with conventional fuel injection. But then again, you can't charge $1500 cleanouts with those. Or goose fuel numbers either.

I do know that Porsche recommends a fuel system cleaning every 3 years.

as i mentioned earlier this is something the industry is struggling with.
I do believe carbon build up can be reduced w/ better design.
Im hopeful that these additives and induction services has help reduce the the build up.

my tech(s) recommends it annually or every 12k.
