Injector cleaner bad?

[Jesda]

Found this on ConsumerGuide when reading about the 300ZX:

"Fuel pump: Adding fuel-injector cleaner to the gas tank can cause corrosion on the fuel injector coils, which will eventually damage them. (1990-94)"

Could this also be true for early Qs too? Or any car?

This would probably be a good question to throw at DeatschWerks.

I don't think adding injector cleaner to the fuel every now and then would warrant enough concern for me to care too much.

Remember that BG44k is the only injector cleaner approved by the factory, i have the TSB somewhere.....

The el cheapo cleaners and some expensive ones contain methanol which is the culprit...[in injector/pump/aluminum corrosion]..........many expensive ones: BG 44k, Techron contain a strong concentration of a detergent approved by EPA for gasoline which doubles or quadruples the concentration of the same thing in the fuel.........in a xylene/tolune solution......1-2-3 ounces of active detergent in up to 8-10m ounces of gasoline like material to pour in and dilute.

Fuels could be made detergent rich for a few more pennies per gallon at the refinery instead of forcing us to pay a 75 cents-DOLLAR per gallon for the same concentrate.

I can assure you BG44k won't affect 1990 injectors having used over 80 cans in the last 15 years and 303,000 miles still as built oem injectors and o rings [they were removed once and cleaned externally].

Bad fuel purchased causes injector problems, along with avaiable to public methanol based cleaners.

Easy to look up chemical contents [code numbers-CAS [not college alcohol society]: Chemical Abstracts Service] on web.

http://www.bgfindashop.com - you can find local shops that perform BG services and will most likely carry their products.

http://www.ebay.com - careful of shipping prices...

or,

http://www.froogle.com - at least one place that will sell it by the 1/2 case for about $160.
