Fuel Injector Cleaner?
Just wondering if any of you guys run this once a year or at any specific interval?

99-Boxster-MK:
This was on the PCA Tech Site:
"Porsche originally came out with bulletin number 8510 "Cleaning of Fuel Injectors" on December 6, 1985. This bulletin recommended adding 20 ounces of "Techron" to a full gas tank and refilling the tank at half empty with fresh gas. This should then be done 2 additional times. Your are not to use more than 20 ounces of "Techron" within 3000 miles. Then add the "Techron" to every 5th filling of the car.
Porsche still recommends that fuel injectors be cleaned similar to this with a high quality fuel injector cleaner. At the time when this came out many of the gas companies only put cleaners in their top of the line fuels. These lower octane fuels such as the 87 and 89 would start to gum up the injectors and valves fairly quickly. Although most of all the fuel grades have cleaners in them now we are faced with other problems. These being the tightening of the emissions controls of the automobiles. Any deviations in the combustion of the fuel will cause a response buy the DME. These responses can be the retardation of the timing, leaning of the fuel systems and other basic mapping characteristics. All of which means the loss of power. So always use a high grade gas and use a high quality fuel cleaner when used. Preventative maintenance is always better for you and your Porsche. Scott Slauson - PCA WebSite - 12/1/2004"

I recently purchased a Fuel System Cleaner from Chevron (containing Techron). It was $9.99 for a 20 ounce container- SUV size- enought for 20 gallons. The instructions recommended using it every 3,000 miles. Probably does not need to be used that often.

I have always used a good fuel injector cleaner in my last BMW M cars with very good results... as a matter of fact, I used a bottle in my new 01 S this weekend!
Definately a twice a year thing. I usually fill up with super as usual and then add the injector cleaner.
Best of luck,
Joe

When I run Chevron gas consistently, there appears to be no need for the cleaner.
However, as I bring new Porsche's in stock, I almost always have to run the cleaner through them and then fill with the Chevron Premium fuel.
Nice when a product lives up to its hype!

Hi,
An equally effective cleaner, but much cheaper is Toluene. You can buy this at any Paint Store for under $5/gal.
Add about 6 oz. when you fill up and you'll never have clogged injectors. It has the added benefit of upping the Octane rating as much as .5 points.
BTW, Toluene is a normal additive in many gasolines and is used as an Octane Booster, so there's no incompatibility issue whatever. Techron is merely Chevron's Trade Name for Light Aromatic Solvent Naphtha. Hope this helps...
Happy Motoring!...Jim'99

Here is an article on toluene. Pros/Cons and what it does.
http://www.elektro.com/~audi/audi/toluene.html
If I just emptied a tank that had 91 Octane(highest availble in Sacramento region) with Chevron Fuel System Cleaner in it would I be ok to put in toluene when I fill up?

Blinkwatt, I think you should use Jim's advise and add about 6 ounces (1 cup is 8 ounces as a reference) of Toulene at fill up's as a fuel injector/system cleaner.
If you want to boost your octane, you'll need to add more. They gave good advice in the Q&A in the article that you referenced.

FYI.
Per Jim's advice, I purchased a gallon of Toluene today, to be used as my routine fuel cleaner. It was $16.26 (Ace Hardware) for a gallon- good for 21 fill-ups.
Not as cheap as Jim thought, but still a ton cheaper than the stuff in the "fuel cleaner" aisle at the auto parts store. That stuff is about $4 for a 12 gallon tank treatment.

Hi,
Yea, I have to admit, it's been a while since I bought any at a Paint Supply. I was just at Menard's the other day and noticed that Toluene had Spiked to about $12/gal., still, if you buy in those nice, little, pre-packaged 6 oz. cans, you're gonna be paying somewhere between $85 and $115 for that same gallon of Toluene...

Hey Jim, thanks again for the tip! I tried buying it from the paint store (a good one too!) and they did not have it. I was surprised.
