This stupid stuff killed my 7. I put it in my 7 just today, I took it out for a drive to get it running through the system, and I get a mile down the road, and my car starts acting weird, so I pull off, and it stalls, so I let it coast. Now I start it up, it starts fine but will not idle, and I can't get the thing to move far. I put it into gear, and the car stalls, no matter how many rpms, this stuff killed my engine, It also sounds a little funny and when the engine is at around 1000 rpms it shakes like crazy, I think it blew an apex!!! I haven't been able to take the plugs out and check compression, but I am hoping that is not it. Is there anyone who has tried this stuff, are you not suppose to use this on rotaries, I looked all over the bottle, and did not see anything about not for rotories, or only for piston engines. Thanks any help would be appreciated, I sure hope it's not the engine, as I just got done changing this out, a little over 120 miles ago.

Well, I just went out and took out the plugs, they were unusually black!! and I just put them in when I changed the engine 130 miles ago. I turned the engine over and heard three even whoshs, but they didn't seem quite as high, or loud, could this of blown both rotors, I don't have a compression tester, but will look into buying one tomarrow. Also one other thing, when I took the other engine out that was bad before, the back rotor was shot, I noticed this same dark black look on the bad rotor, plugs too.

did u try cleaning the plugs and starting the car agian?

What he said.

I saw a post recently about how Lucas is only good if pounding on your OMP is your goal, but I'll be damned if I can find it tonight.

Do keep in mind that it could be something totally unrelated to the Lucas snot. Things die when they die. It may just be a coincidence.

Following a huge nuclear fallout in southern South America, thousands of sheep went blind. Upon conclusion, scientists deemed the radiation to blind them. Several months later they revised that conclusion -upon learing that the sheep went blind NOT from radiation, but rather a nasty viral/bacterial infection

point being : coincedences can happen. I dont see how a fuel treatment could **** an engine over that much

KFelkner02

Ok, I'll try cleaning them. I know it may seem a coincedence, but I still think it has to do with the treatment, since it happend at the exact same time, as when I put it in, what I think I had concluded that maybe my engine was on the edge of dieing and the stuff made it run hotter, and blew the seals. I'll get back soon on the results.

I dont think i'd trust anything that has a counter display at pep boys

KFelkner02

yea..well I just had this stuff sitting here, and my car showed no signs of death until after I put it in. My 7 ran just great, but it started a little hard you had to put your foot on the gas to get it to start, so I thought well heck if I put this in it should fix that problem. Yea it seemed to fix that problem, but now made another big problem. I was wondering is that deep black color, ok or does that mean that something went wrong in the chambers, Like I said I just put them in about 130 miles ago. I also didn't get the plugs cleaned, yet, what should I use? Some carb cleaner?

i used that stuff like 2 weeks ago and it hasnt done anything to my car... if anything it pulls a little better to 7800 rpm.... honestly... i dont see how it could kill ur engine...

KFelkner02

Well bad news, I just cleaned the spark plugs, and made them all shiny again. I put them back in and started the car, and nothing changed did the exact same thing, it would start ok but... it wouldn't idle lower than 1000rpms, it just shook the engine, really bad, so bad the exhaust was making rattling noises. Anyway, I also forgot to say, it was also smoking, it wasn't coolant, it smelt like a fire almost. Anyway, if I would just leave it sit there with my foot on the gas, and let it run for maybe 5-10 minutes, and shut it off and it would smoke alottttt!!! I opened my hood, and smoke came pouuring out, it eventually stops. That is exactly what I thought, before I did put it in, my dad told me I shouldn't put it in, since he has never had results, from them. I figured well heck nothing could happen to the car from doing this, maybe even make it better, yes I don't admit that it was probably a coincede but, I still think that the fuel treatment, did something to my car, since the timing was perfect. I just really wanted to know if this stuff was for my car but you guys have all helped me a tremendous.

How much did you put in and how much gas was in the tank? And, which Lucas product did you use, the additive, stabilizer or treatment?

You went to the gas station, added the Lucas, and then filled it up so that the oil/gas would mix properly, right???? The Lucas has all the properties of an oil. It is no worse than adding motor oil to the gas(omp), or adding 2 stroke oil/MMO, or using a bottle of FI cleaner.

You need a compression check. But first, you need to check EVERY electrical connection, vacuum line, every sensor..... The magic word is COINCIDENCE which is mentioned already. Whatever blew your first engine is working on its second.

And, if you had a "hard to start condition", no snake oil in the gas tank will fix it.

And, of course, one of my favorite quotes "Don't blame the fluid, blame the owner."

ponykiller

IS there still Lucas in the gas tank? If so, try removing the gas/oil mixture that is currently in your tank and refilling it with just gas.

Try that, then check all your electrical connections.


good luck,
Kris

rx_7_driver

what was the color of the smoke? blue? black? white?

KFelkner02

Well, I have checked all of the, electrical connections, and vacuum. I didn't blow the first engine I just bought the car, and it was blown, so I had a good engine (this one) sitting in my other 7, which had a problem, with the tranny, so I decided to switch them, since the one that blew up the other day is a year newer, and it is the GXL. I was told that I could either switch the injectors, and wiring harness, or some various stuff behind the headlight, to get this engine to work in this car. Well I changed the harness, and injectors, since I have heard that high impedence injectors seem to work better, which is what the blown engine had. Well the car worked without a hitch, right after I got everything back together, and I had noticed that you had to push the gas pedal down to start the car, which I heard is not normal for these cars, so I thought that these injectors might be clogged and need cleaning, since I really have no money right now, I couldn't send them out to get proffesionaly cleaned right now, so I figured that the Lucas Injector and upper cylinder fluid would help fix them, at least for a temporary until I could get enough money to get them cleaned proffessionaly. I had only a half of a bottle left since, I used half of the stuff on my other injectors, I was told by a guy at Advance Auto Parts, that If I stuck my injectors, in this stuff over night, it would help, well it did, and now I wish I would have just used those injectors, because I wouldn't have put this stuff in. Anyway, I had a little less than half of a bottle left so I was going to go and fill my tank up, but decided not to for fear of it dilutting it to much and doing nothing so here I had a little over half a tank, and a little less than half a bottle. So knew this shouldn't have effected it any, after my car starting to act funny, went and got about 5 more gallons of gas and mixed it in with the others, and still no difference. I don't really remeber the color, of the smoke I think it was whitish blue, and the odor was kindof buring the nose to smell it. And to go back to the other bad engine I found out that the kid I bought it off of, had never taken care of it, I don't know if he didn't know you had to change the oil, or what but he said he never changed the oil in it through 2 years of his ownership, which seems kind of wierd because he took real good care of the inside, he mad leather covers for the console, the stereo surround, and leather seats for the car, and I got to tell you it looks awesome. I also had noticed that the smoke I was talking about was coming into the passenger compartment. I think I might call Lucas tommarow and see if there has been anyone else with this problem, and see how they fixed it, but like I said I fear the worst, a BLOWN Engine. When this happend to me it was wierd, I was just cruising down the street, not even going the speed limit, I was just like I said not trying to race or anything, I was just trying to get it worked in. Sorry for such a long post, but I am so frustrated with this car, now I wish I would have spent my Grad. money on something else, all though these cars sure do run sweeeet!!!

KFelkner02

No this is my first car, and I have never, done this before, and there was no instructions on the bottle, I just figgured you pour it in, and go.

rx_7_driver

well if the smoke is blue its oil and if its black then u r running rich or have leaking injectors (correct me if i am wrong)

krazie_insane

my first n/a did that exact same thing when i put that stp 4 clyinder treatment in it the fire smell damn made me wanna puke and smoke rolled out from under my hood too so i drove the **** out of it back to the lot and had them look at it

KFelkner02

Well, I can't drive mine, the car just stalls, with gas pedal all the way to the floor, it moves a few feet and then, stalls. I kept trying to floor it to keep rpms, up. But it wouldn't go any higher.

KFelkner02

Well..I was just sitting thinking some more, I knew I forgot something, after holding my foot on the gas for about 5-10 minutes, above 1k rpms, (due to it shaking real bad at any lower) There is a little buzzer that comes on almost like the over rev but, it has real short beeps, and is real quite tone. Now hopefully I didn't forget anything.

i8acobra

i hate to be a repeater if this has been said, but my car was doing the same thing, i didnt use lucas though, i make my own octane booster/fuel treatment stuff, anyway, it would start and run, but would not climb in rpm very easily and would not idle, guess what it was, fuel filter, might as well replace it, its what? 5 bucks? lol, give it a try, i bet thats the prob ;-)

KFelkner02

I had already, changed fuel filter, when I changed the engine, but tomarrow, I'm going to drain all the gas, and put in a fresh filter, and fresh fuel.

This sounds exatly what my 86 was doing. when you get it started have some one pull the hose on the intake tube. if it smooths out a little you are running too rich. change the water temp sensor in the filler neck. I also changed teh air intake temp sensor. this fixed the problem all together. my BAC valve was also skrewed so I unpluged it

Lucas products are very very good IMO. Some of the best. And as for being on display in Pep Boys, that is new, because at until now (at least around me), I had to drive about 45 Minutes to a small hole-in-the-wall parts store just to get the stuff. Thats how much I like it. I passed several Pep Boys and Auto Zones and Advanced on the way there, just to get Lucas Products. I use the FI cleaner regularly, with nothing but good results. I dont see how it could blow the engine. Granted it may make it run slighly hotter beacuse of the injector cleaner, chances that it alone blew your engine are very minimal.

KFelkner02

Well, I drained all 10 gallons of the gas out, and put new gas in. I didn't replace the filter because It didn't seem it need it changed, since, it was flowing pretty freely, anyway I let regular gas run through it before I put it back on. But, now it will not start, it acts like it wants to sometimes, but doesn't. Anyway, I think I know why it was smoking. I pushed the car up, and noticed a big old black spot on the grass that looked like it had been burned. I'm not sure how this happend or what made it burn the grass, but there is something horibbly wrong.
