Whats you opinions on this? Do you have it done in the shop or do you just pour in a bottle in the gas tank? If so, What type of stuff do you use?
Reason for asking cause my car seems to have lossed HP so I went ahead and did a “professional” fuel system cleaning at Jiffy Lube for about 50 bucks. They place a bottle hanging off your hood with a tube going to the injector hose while it takes about 15 minutes to clean with engine running. Drove off the lot and didn’t feel much of a difference in restored HP. Discuss.
Did you do a before and after dyno? Otherwise it would be extremely difficult to tell you have lossed HP unless it is very major (i.e headgasket…etc.).
well whenever i go on a long trip where im just going to be driving highway for a whole tank i’ll throw a bottle in. but i dont expect anything, at least nothing that you’re gonna feel. lucas fuel injector cleaner is what i use.
Save the money and just use higher octane fuel. It serve as the same purpose of using the store bottle rip offs and most time doesnt work.
For example; I always go walmart alot and when i do i care to stop at the auto section. Til this day guess what they have created V-power shell bottle. About 16 oz bottle maybe? and its like close to $6 bucks? WTF I rather pump full 91 v-power and probably get the same thing. Those bottles were made for dumbasses that dont pay attention nor never care to think pumping expensive shell gas so they do this to make dumbasses think that it would help and it may who knows. Like me every 3-5 fill ups i go with the highest octane just to keep my engine flushing clean otherwise i use the lowest grade shell or cheveron.

You want restored hp? Just change your oil, then take all the junk out of the trunk(everything), then also change your spark plugs to iridium x. It should save you the mileages as well. Then advance your timing to 18 degree correctly done then try using 89 octane. You will feel the restored hp becoz u will feel the lil pull or zip how ever u want to call it.

Since you are in sac come by and we can take a look at your ride. I have timing gun and everything. Perhaps i can explain a few things as well.
I have found that those semi-cheap (@$20) ultra-sonic cleaners, like the ones for jewelry do a great job of cleaning them. You could mix whatever you would normally put into the tank with some distilled water for a solution to use in the u.s. cleaner. Of course this requires removing them. I’ve seen this restore injectors that were throwing codes before.
The ultrasonic cleaners are what places like RC use to clean injectors. Except the machines they use are going to be MUCH MUCH better than a $20 one you can buy. The nice machines are quite expensive. This is one of those cases where you get what you pay for.
My father has a professional jewelry ultrasonic cleaner and I also used it to clean my injectors. It worked OK, but after really looking into it more and seeing how clean mine got I determined it was nearly pointless. It does clean the outside, but that’s just about it. It’s not going to improve flow all that much. When you get the injectors professionally cleaned they actually run current to the injectors so that they open and close, this way they get the cleaning solution inside and out.
Don’t bother with the crap you can buy in a bottle at Kragen. And the fuel system service at Jiffy Lube sounds a lot like the SeaFoam product to me from what you’ve said. I think that stuff is good for cleaning out some of your parts but still won’t clean your injectors as good as a sending them off to be cleaned by a place like RC Engineering.
Why do you think it’s your injectors which have caused a loss in power?
