Fuel Injector Cleaners

[adal20]

Did anyone used fuel injector cleaners ?
Can they damage O2 sensors ?

Some independant repair shops have a commerical injector cleaner system, where they inject a water solution thru the system and supposed to be the best.
I use Seafoam (1 can to 10gals of gas) additive and Marvel Mystery Oil (3oz. per 10 gals)in my fuel system, and have "never" experienced any problems, and always seems to help performance and slight fuel mileage increase, unfortunently not with my XL-7?
Check out with independent repair shops, dealers always seem to be much higher in repair/labor costs.

The best way to clean them is to remove them and get them cleaned (usually ultrasonically) and the spray pattern checked. I'm a bit dubious about the worth of those systems that supposedly flush them while they're fitted.....

To be perfectly honest in school I had been using Redline SI-1 and my car blew cleaner on a 5 gas machine than any other car including almost new Hondas. THe Hondas and Toys caught up after injector cleaning but mine cam in that way. I got permission to have a fellow student try the SI-1 as an experiment and then service his car the next time we were in lab 3 or 4 days later. It was dramatically cleaner in the 5 Gas and fuel injection cleaning was only a minor improvement after that. It had already been running much better. His car was 16 years old and had over 200K. He had about 80K without ever a injector cleaning.

Do some better cleaners work YUP. Do they cure all, NOPE. But what it can do is sometimes amazing.

If you want to try one, I can honestly recommend SI-1 from Redline Oil and is available at pepboys. I do not have stock or connected to either in anyway.

My O2 had never failed I had used it frequently. My current car (a dodge) had a primary failure but it was external shorting in water (ran fine in dry weather) that doomed it.

Yes, sorry, I was more talking about if you've got serious injector issues (like it's almost blocked) then I reckon the only option is to remove them to fix the problem.

It's usually not that expensive to get done providing you can remove the injectors yourself.
