anyone? my car has been sitting dormant for 4 months. so after a fresh tank of gas, and oil change, i just want to be sure there's nothing else that could have possibly built up.

 

yeah it says in the manual to not use it with these engines.

 

Injector cleaner is not needed with direct injection.

 

i would assume this is because the injectors are in the cylinder and the combustion keeps them clean.

 

Yes, you are not supposed to use any fuel treatment like that with the ms6. I assume it's because it's hard for an injector to get dirty when 1600+psi of fuel is flowing through it.

 

Just to play the devil's advocate, I have noticed that numerous car owner's manuals attempt to deter any use of fuel additives/cleaners. I would imagine that having a 1600psi blast moving through the orfice would keep it pretty clean but there is always the possiblity of films and gunks that could exist elsewhere in the fuel system. I haven't used any personally but I think what the manual is concerned with is using additives that might contain corrosive chemicals. I wouldn't think that a reputable "safe for modern fuel systems & O2 sensors" additive would hurt anything. If you use good fuel and the car is running well, I don't see a need though.

 

thank you so much for the help guys. youve saved me a hassle.

 

go fill up on some shell v-power if you are worried.

 

I run injector cleaner every 3,000 miles in mine, I'm at 25,000 miles right now and the car runs great.

 

I know the manual said not to use cleaner, but I've been using fuel power for several years for both of my cars.

Most likely due to that injector cleanor you're using

 

I use Fuel Power with more or less every tank. It keeps the whole fuel system conditioned and isn't designed just for the injectors.

 

My dealer tried to sell me a feul injector cleaning service @ 24k. He said that the car had a hesistation- one that i've never felt- and that we should clean it. I declined the service and called a personal friend who happens to have a perfomance repair shop. what i was told exactly is that todays gas has an ethanol detergent mixture and that mixture IS a feul injector cleaner. He said that he doesnt even offer the feul injector cleaning service anymore.

BINGO!! Due to EPA regulations and performance advantages, gasoline sold in the USA already has detergents in it. Maybe if you use cheap gas you should consider it (kind of destroys the purpose of being a tight wad if you have to buy this stuff though) but, like someone mentioned above, a good tank or two of v-power should do the same thing.

i dont think you have to run it that often, i highly doubt they get dirty that quickly.
