I had a problem with a sticky injector, used Lucus injector lube and cleaner, it worked great.

 

Clean injectors on a 3 yr schedule.

Well, The filters are in place so I'm not sure what else to do. I can't change the fuel and it's properties.

Well, if the tests came back that there was something changing the spray pattern and volume, what is it you suggest I do? Leave it till it gets hopelessly out of whack and you can notice something? My diesel injectors are done every 100K at that seems to be the interval but the gas injectors seem to get dirty more often

 

I love Lucas fuel treatment. I put it in every tank in my driveway every three or four fill ups.

 

Hi found it! old post were Jon from fIC tells his views on fuel injection cleaners and harm they might cause. he said 89-93 multec injectors have a epoxy seal covering fuel orifice from coil housing, that much use of cleaners could cause coil in injector to fail. Also that small screen in injector can get plugged.Old post is at http://forums.corvetteforum.com/c4-t...cleaner-2.html

 

friend, someone placed the advantage of a certain spray pattern in your mind, because the multecs have run for millions of miles without the owners noticing a "problem." which pattern is more susceptable to clogging, the Bosch or the multec?

what's the goal of all advertising? "create the idea, then the need, and sell the message, or the product that satisfies the need." your logic is totally backwards. if the engine was "perfect," why would anyone need to send the injectors out to assure them it was perfect? and, what assurance would we have that it was stlil operating perfectly once back together -other than the obvious, the way it "feels?"

if you flew a small plane, you'd know that most of your attention is outside the aircraft -not watching instruments that might be incorrect.

as for this Biker thd, you label his product, "wrench in a can," or "snake oil," but the ones you use are intelligent, phragmatic choices. he's throwing pennies at the solution while you throw thousands of dollars.

 

I've used seafoam and techron. Once a year or as needed, more as needed than anything. Haven't had any issues. But too much of a good thing is always bad.

 

Tht's a ggod find! Thanks. I have often wondered about loosening the crap in the system and what harm it can do later down the line somewhere myself. I don't flush my cars all that often actually but I do see the need to get the crud out of the lines and such once in a while.

On the C5 it's almost a have to because of the sensors on the fuel take/gauge. If they aren't kept clean the fuel gauge will go south. Another engineering marvel of the C5. 2 tanks sending units and cheap parts to make it all work.

I know we're talking about the C4 but some C4 owners also have a C5.

 

OK. Fair enough. Now tell me how come my flow rates were different after 3 years. The only options I see is that Jon lied on the flow rates or it was getting clogged. On my diesel injectors, I did see the spray patterns in the chamber and it wasn't good. So, unless that was an optical illusion as the volume collected and the gauges, what is the explanation?

As with the above example, how would you feel that difference? I am not good with this feel thing so I use indicators. Injectors crud up over time or so the tests show me. The change is gradual so unless it fails today from an operating state yesterday, how would you know? Feeling is good only if it is Boolean. Today work, tomorrow quit 100%. But what if it creeps SLOWLY down? While we are on the function of advertisement, don't those "cleaner in a cans" fall under advertisement too? Create a need and fill it?

I don't but if I did, I suspect I would trust instrumentation way more than my feelings.

Actually, less than $200 every 3 years. But unless Jon or RC Engineering faked the tests and my buddy at the tech college rigged the flow bench, I can see what I sent in and what came back. I picked a 3 yr schedule because when tested, I seem to have flow differential and when it comes back, the differential is way less. I am not sure how you would explain that. OTOH, When you dump a "cleaner in a can" into the tank, how can you tell exactly what was done? Can you see if 50% of the crud was removed so you need another can or two? IF you clean a gym in the dark, how do you tell what you cleaned? Feel around and gauge it by the pile of dirt and assume it is clean?

 

whatever. if anyone wants to take injectors out and flow test them every 3 yrs, when their "sensations" tell them the car is performing great, go for it.

we don't need a weatherman to know which way the wind blows. stick a wet finger in the air.

also, we can't argue boths side of an issue with the same points. I know I'm still alive when I wake up with a warm body next to me. I believe my car is running great when the sensations -speed, sounds, reactions to throttle, etc- tell me.

when I suspect an injector issue, I'll use "wench in a car."
