Injector Cleaner

jro909 · December 11, 2009

being bored at school i began looking into fuel system and injector cleaners, and theres quite a following of folks saying the stuff is very damaging to the motor, saying something about fuel backwash into the oil? i assume this is pure crap but what the hell do i know

If it was dammaging to the motor you wouldn't have just about every manufacturer having a injector cleaning proceedure for warranty vehicles. That would be setting themselves up for big dollar engine repairs.

will this clean the pump and everything too or just injectors and cyclinders?

Well...it goes through the pump...It should clean anything the fuel touches.

I was adding 3 cans of Seafoam into the fuel tank at every oil change (5K). Couldn't tell ya if it physically does any good. Mentally, it works just fine.

I've since changed over to ChemTool because of the cost.

Yup you know more than you think...or give your self credit for.

Those guys are full of BS.

They too will know as they're fuel economy slowly decreases...than the build-up on the injectors gets so bad that they either start stalling...or the fuel pools in the cylinder and they get detonation and burn a hole through the Piston. Or the deposits that form on the pistons....Carbon....soaks up the unburnt fuel to the point where that ignites, ending in holes in the piston too.

At least once a month man....I toss injector cleaner in every 3-4 tanks.

I do it once a month...but as long as you do it regularly you'll be fine.

I ususally run it in the trailblazer every oil change. It's hard to measure if it's doing any good or not but I have had it cure some minor intermittant missfires on vehicles at work so I stick with it.

2nd question, it says treats up to 20 gallons, does it mean i have to run it with 20 gallons? if i don't would it be too concrentrated?

I pour a bottle...into an empty tank...than fill it up. Too concentrated wouldn't be bad...but too diluted is useless.

I have a 26 gallon tank...and I use one small bottle of Lucas with a full tank.

i have a 36 gallon tank, i have never filled it up, i was just inquiring about the 20 gallon mark because id run it to the fuel light, drop the bottle in and then pump 20 gallons into it..is that kosher?

Haven't heard of that happening since there were carburetors on the engines.

Hey how do you like the Lucas fuel treatment..? I can always get it on sale, and I picked up my Suburban with 60k miles on it. So far I threw one bottle in the tank and was wondering myself if I put a bottle in once a month if that would be ok on the preventive side.?

I like it man...has always worked for me...I do it every 3-4 tanks...which is about once a month.

We worked on a 97 jimmy a while back that was stalling and sputtering...we put a full small bottle in the tank...maybe 5 gallons of fuel in there...and we ran it at 2000ish rpm for 5 min...there was no sign of stalling or sputtering after.

Only reason we did this is because the customer told us that he had never used injector cleaner in it since he bought it....that was 65k km ago...so as something cheap to try and save the guy some money...we tossed a bottle in....and what do ya know...it worked. Cost him 5 bucks for a bottle of Lucas...he was happy with us.
