Can "fuel injector cleaner" treat any effects on the engine from unstabilized gas over a 5 month during winter storage? I took the dealer's advice and didn't add fuel stabilizer for my first winter storage. I know better now that I should add Stabil. I am worried about any gum deposits on the fuel injector system and carbon deposits on the engine. The car idles well, smooth, but perhaps acceleration is a tick slower than I remember when I first got the car a year ago... Maybe, I am being paranoid or getting used to all the power.
QUESTION: Should I add fuel injector cleaner to treat the fuel injectors and engine?...

I'd appreciate any advice/help on this issue. Thanks.

 

Hi..

As you stated definitely a good idea to put in some Stabil (though it will smoke when you use it again) if you are going to leave it sitting for a while....But you are already past that.

You will get as many opinions as there are subscribers here, so take this in the context delivered I have had good luck with SeaFoam additive to fuel and actually add it to oil a few hundred miles before changing it. I actually got this recommendation from a Porsche Master Mechanic at my dealership....He has been there for 25 years....Seems to know what he is talking about and knows everything about Porsches...Awesome at repairs.

So I would suggest adding a bottle of Seafoam. They have a good and informative website as well. It does not have any harsh additives that may damage internals, hoses, etc.

Good luck!

Startron. Look it up. I use it on all my motor toys.

 

I use Fuel-Medics Fuel Treatments in all my piston engines. Look them up very highly concentrated additives that increase power as well.

 

Great guys, thanks! I have 1,400 miles on the car. I just had oil changed.
1. How often should one treat the injectors/engine?
2. Should one add it to a full or partial tank of gas?

 

If you run ethanol fuel(E10) it's a good practice to run it every tank. Adding the additive prior to fueling up will insure it will mix well with the fuel. It's also a Octane Booster & Fuel Stabilizer. Best on the market. FuelMedics.com

 

There dealer here in Plano, Texas uses BG 44K.

 

I've searched this forum up and down but can't seem to find anything regarding the Seafoam process of sucking it through a vacuum line and intentionally causing the engine to die. Then letting the Seafoam stand for about 5-10 minutes and then starting the engine back up and watching all the carbon billow out through the exhaust. There are tons of articles on other forums laying out the steps and even more videos on YouTube (search Seafoam exhaust).

Anyone try this method?

I've done it on an older Camaro Z28, Pontiac Grand Prix GT and Silverado with amazing results!

 

At my mechanics recommendation, I've used Red Line fuel system cleaner for the last few years. Good stuff. Not cheap, but only an once or two added to each tankful.

 

Seafoam works quite well. As a word of caution, for this tank of gas don't push the engine, no full throttle runs and my advice would be once you have half tank of gas left go and fill it up with premium and add some more additive and drive around till the gas is gone.

 

I've used RedLine in the past without any problems.

 

Think that mainly for DFI engines since otherwise you wont reach intake valves.
