Will sputtering from running out of gas cause engine damage ?

Im getting quite aggravated lately because in the past week my car has done this on 4 different times, all because my boss never puts in enough gas in my car and leaves me with like the smallest amount just barely to make it to my house.

It will stay running and sputter if i hit the gas too hard but i know its from lack of fuel, i just want to make sure it cant cause any engine damage because its getting quite annoying.

It will damage the injectors by picking trash up from the bottom of the tank. Otherwise it's no different than using a fuel cut switch to start it.

that cant be good , i just had my injectors cleaned...but shouldnt the fuel filter , filter anything bad out before it can get to the injectors ?

this hasnt happened too many times just 4 in past week and maybe ran out of gas once before entire time after the engine was rebuilt, it just pisses me off because i put plenty of money into this car to keep it running good so least i should get is enough gas to drive without running out /sputtering


I really dont even want to drive my car to the gas station tommorow sputtering after hearing it can **** up my injectors, id rather walk there with a gas can...its just all for my piece of mind, he doesnt understand this car means alot to me and i dont like anything being a way it shouldnt be if i can help it ( like running out of gas). Id say ive invested $5000+ in parts/engine rebuild and done damn lot of work myself prolly $2000+ in my own work so like i really enjoy running out of gas.

so, run this by me again. YOUR BOSS fucked up his car hardcore. YOU invested $$ into your 7. He has been driving your car. YOU'VE ALLOWED HIM to abuse his power and your kindness and you're NOT gonna bitch him out?

If you're able to let him borrow your 7 then you should be buddy-buddy with him enough to say: "Look bitch, I can let you borrow my GF and i won't mind if she can't walk afterwards. BUT YOU'RE ******* UP MY SEVEN AND I WILL NOT STAND FOR THAT ABUSE!!!! Either start putting in gas or start taking the bus!!!" then Pull out your ***** and say "SEE THIS????? I didn't want it to come to this but YOU forced me to," *SMACK!!!* right across the face. I think this should cure your sputtering problem.

The fuel filter can olny do so much and if your injectors fail your engine fails. Tell your boss that he's breaking your car and if it breaks he'll have to pay for it.

Im the one driving the car , but again i still feel like a damn taxi driver having to run everywhere for him and the fuel injectors have been cleaned/tested which i had to pay $12 per injector for and i would hope the couple times its done this isnt going to be bad but I dont want it happening anymore.

Its quite obvious that anything that is bad for my car is going to **** me off, thats why I made damn sure that i do all preventive maintainence i can afford and keep up with all the scheduled maintainence as well (oil changes etc).

If my car were to **** up due to the injectors getting messed up because I ran out of gas i would be very pissed because like i said i have thousands of dollars and countless amount of time in labor on this car....so what little money it would have costed to not run out of gas is nowhere near what ive had to invest to make this car run as good as it does now and i dont want anything ******* it up, or hell will break loose.


update - also when sometimes the car seems weird when im on the gas partially ( as light throttle i can give) , the car will make this weird noise and it wont be accelerating it will almost sound like its not getting any gas just like a weird sound almost like im letting off the gas like a muffled kind of sound, surely if i press the gas more it stops doing it and when the car is more fully warmed up it goes away more it seems but it still seems really strange to me


Also , should i be worried or will i be fine ? I just want to know my car will be fine, and im gonna make damn sure my car has gas in it and doesnt do this again, i may even need to get a gas can to get gas for my car so i dont have to **** up my injectors more since theres no gas in the car really and it may start sputtering on the way there....just more aggravation.

Dude, did u not read the post ? How the f** would i replace the fuel filter everytime its been low if its done it 4 times in the past week.

The fuel filter was replaced with a brand new one before the rebuild was installed 5000 miles ago and all the fuel injectors were cleaned/flow tested.

I believe fuel injector cleaner or whatever it is , is not really good for rotary engines...but i could be wrong.

If my car is fucked up or anything is , im going to be pissed because its my bosses fault for giving me jackshit for gas money and not caring whether or not i run out.

Will my car be fine the way it is now ? It seems to be running alright aside from the one thing i mentioned that seems weird, it just really pisses me off because all this was not my fault...everytime i put gas in my rx7 i fill the ************ and top it off, i dont put no measley 5 to 10 dollars incuz that **** doesnt last at 2.75 a gallon and 20mpg (70-80 miles for 10 bucks roughly)

Upon thus being said, the injector cleaner could break up any buildup PAST, and actually before, the injectors that could be interfering with you fuel flow. The injector cleaner won't harm anything, though maybe degrade a seal a small bit faster, I use it every 3rd fill and have yet to have any problems. (I drive about 1-2k miles a week)

Also the sound when barely touching the pedal, does it sound like a hum? Same with mine but I have noticed that it's giving it just enough gas to keep a steady pace, not sped up or slow down (though it does slow a little)
Well dude i cant afford to buy a damn fuel filter and i dont really want to buy one, so will i be fine without getting one ? Im really really pissed off right now so dont mind my attitude.

Can anyone else give a 2nd opinion ? I cant afford a fuel filter i am broke, i dont see why i need to replace it just because of this...its ran out of gas once before along time ago and its been fine..

plus i only have 5000 miles on my new fuel filter sure ill replace it when the car hits like 15,000 more miles or who knows but im not gonna replace it now if its not completely necessary, im sure people have ran out of gas and all liek me more times and been ok , but i dont know for sure i am just hoping ill be fine because i have no other choice in the matter cuz i am broke.

Even if i could afford it , it wouldnt be here for a week anyways, im just pissed off right now, very pissed off...ive always known enough not to let the car go low on gas, but i cant help it when someone else is in control of the amount put in since im broke.

Im just really pissed off because the thought of my motor blowing up is enough to make me want to do some bad things to cure my anger if it did blow up...because most of all , it wasnt my fault any of this happened! And all because im trying to be nice to a friend and give him rides , but it doesnt mean i should have something like this happen, i dont deserve it.

You should be fine without getting one yet, however I would suggest the injector cleaner once or twice. Trust me, I dont mind attitude. I blew a ton of crap on my old Monte before I gave in and took it off the road.... now im waiting ona brand new 350 lol

My RX-7 sputtered when I first put it on the road because it was almost out of fuel and had sat for a while. After the 3rd fill with a bottle of injector cleaner per fill it's running like a champ (well with little, non-engine problems).

Well even if i put fuel injector cleaner in , its suppose to be run when u put in a full tank of gas...which isnt going to happen anytime soon since my boss never fills the damn thing...

I am also not sure if injector cleaner is good or bad for rx7s and if its necessary to do 2 or 3 times in a row (putting in one bottle every fill) , but if thats whats necessary ill do it ...im just very cautiious when it comes to my rx7

If it is ok for rotary, id want to make sure i use the one that would suit the rotary engine the best.

Anyone know which i should use , given its ok to use on rotary engine (dont want to make the problem worse if it shouldnt be used)

also my car is a 88 streetported na, if the matters

I use Prestone for my RX-7. Not sure how good it is for the car, though I have yet to have a problem and my compression is good.

If you do use it and am not going to fill up soon. Say you have a 1/5th of a tank right now, and the 88 tank size is 16.6. So about 3 gallons, toss like a couple quick pours in.

Personally I would milk it, tell you boss that he sorta screwed over you injecotrs and filter by the car getting so low on gas and he not giving anything for it. I meen what 12-15$ per injector cleaned and 20$ for a filter? I'd beat him for it lol

I think maybe the injectors might even be ok without being cleaned with cleaner and all, since they all been cleaned and the fuel filter is new (5000 miles on cleaned injectors and new fuel filter).

I just am flat broke and have no money for any of this, and i really dont want to have to spend money on it unless i reallly have to.

Cany anyone please give second opinion please ?

I am pissed off about it , but my boss will just say its my fault because i drive fast or say that its not gonna ruin my car like hes mr know it all. I just so pissed off now because i know enough not to let it go low on gas, anytime that gas light has come on i was filling it back up...but when he fills it , its like the bare minimum amount of gas to do what we have to, so i have to like ration the gas by driving like a pansy...and who drive an rx7 like a honda civic ? cmon its an rx7, driving it is no fun if you have to conserve gas and rev up to only 3k rpm every shift, and i doubt it really saves that much gas anyways.

Ah, no... Even if you forget about the two filters the fuel has to pass through (which you must've done), anything heavy enough to remain at the bottom of the tank is not going to magically jump up off the bottom just because the fuel level drops to the lowest pick-up level. If this stuff really was a problem, it would be a problem all the time, not just when you're low on fuel. The injectors will be fine.

He has no right to make you use your car if you don't want to. Tell him respectfully and politely that if he can't give you money to put gas in the car for his purposes, he can't use your car. At the very least he should agree to pay you extra in you regular pay packet. If he gives you grief about it, consider looking for a new job. Do you really want to work for someone who can't afford to fix his own car and has no respect for his employees?

That's completely unnecessary and a waste of money.

Yeah this is insane. First off, stop letting him use your car. Don't be a pushover. I'd say make him pay for gas and rent to use the car, but I have my doubts that you'd actually tell him off. I dare you to prove me wrong, I'd be pleased if you would. He destroyed his own vehicle most likely because he's a total idiot. 7's need special attention and with a retard behind the wheel it will fall apart fast.

I was so pissed I forgot the second part. Yeah, running empty on gas is never good for any car, but I'm sure you've figured that out.

One thing that everyone is forgeting to tell you is that running your car low on fuel is hard on the fuel pump, not only is it sucking air but it is running hotter. The fuel pump uses the fuel in the tank to cool itself. You should never run a fuel injector car with an in tank fuel pump below a 1/4 tank or the fuel pump wil burn out faster.

tell your boss you need to leave earlier in order to get gas and if he says no then get gas anyways and chrage him. Keep track of the mileage and the times you've been low and when you fill up. Then charge him for it. If it's a private company then give him the sob story about how you don't want your car to die because then the TWO of you would be car-less. If it's a large company tell them they NEED to compensate you with the gas/maintenance and all that crap.

like ive snothing will happen to the car. nothing will break, and nothing will explode. it wll just stop running. you serriously think that fuel injected lawn mowers that run out of gas and have dirt and **** in the tanks need to ha ve the fuel filter removed every time it gets empty?

What's your point? Once empty it can still ruin the fuel pump.

Well im the one that actually drives, but im making sure i bring a gas can to fill it and not drive it there with it on e sputtering and then put even more gas in after i fill it with the gas can.

Im really sick of running my car low on gas, its quite annoying....I cant even go anywhere or see no girls

I wasnt replying to the damaging the pump part. I meant, why would running the gas low cause it to suck junk in, the pick up is at the bottom anyways.

Yea because it takes a huge piece of debris to stick an injector right?

Just about anything solid will sink. That doesn't necessarily mean it has to be large enough to avoid getting sucked into the pump.
