Best "Injection Cleaner" for CIS?
 

Just curious is there is a preferred "injection cleaner" for CIS cars. I've used Teckron in my EFI cars...is that best for CIS?

As an aside, what's the difference between a good "carb cleaner" and a good "injection cleaner"? (..besides the obvious..)

Thanks!

Techron is reputed to be very good. Berryman's B-12 Chemtool is still a favorite, and has been for decades.

Adding the word 'Injector' to the can or bottle ads about $5 to the price, IIRC!

I have used both Techron and B-12 ... and have seen improvements in gas mileage with both. My real problem with the Techron hype is that there are too many different 'versions' on the shelf!

B-12 Chemtool seems to work as well as the 'best' Techron if you use two 15 oz. cans in place of one bottle of Techron. Note that B-12 used to come in 16 oz cans ... and I don't believe they changed the formula, either! B-12 used to be available in one gallon cans and five gallon buckets ... both stores here that carried it have gone out of business, though!

I prefer BG, which you have to get from an authorized dealer. I get it from the parts guy at my Porsche dealer. You have to add it to a full can of gas, or it may dilute your engine oil.

That's what I was afraid of! :p How much difference can their be?

I'll stick with the Techron. (I don't think I've ever seen B-12?) I just didn't know if there was something better for CIS or not. I'm guessing not really.

How would a fuel injector cleaner added to your gas dilute your engine oil? :confused:

Carl,

It is sprayed into the cylinder, and builds up, or begins to wash down the oil on the cylinder walls. Same for Techron, which is why they say to add it to a full tank of gas, and not a half tank.

learn something new everyday. thanks.

Yeah...interesting.

Have your injectors tested........you might be surprised, I was:
