this is a bit of a weird question, but i want to know what you guys would do if you were in my situation.

i just picked up an 88 iroc. its got a little over 75k miles on it. the carfaxs last reported mileage was at 73K when it passed emissions back in 2001, the last time it had registration renewed was 11/06. with that said it really hasnt been driven much in the last 8 years (only about 2400 miles). do you think its worth it for me to drain the gas? from what i can tell (and i dont have it reg, so i havent driven it but a couple hundred feet) it run well, no hesitation or anything to suspect the gas is bad. should i just throw some dry gas in to get rid of the moisture that my be in there, or should i drain it? i will also be replacing the fuel filter this weekend. i want it to be in tip top before i drive it any long distances.
thanks!

 

If its running ok on the old gas, I'd probably just fill the tank with fresh gas and try to drive the entire tank off quickly. Maybe use a fuel treatment if your really worried.

 

Thanks. Do you have any recommendations for fuel treatment?

 

If I were you, I'd put some Seafoam in there. You can buy it at any parts store, should be about $8 for a can. If that doesn't help, put some Heet in there too. The seafoam should do it though.

 

i acutally have seafoam, bought it the day i got the car. talked to some people on this site and they basically told me it is a bad product and tends to clean the carbon/engine too well. that it would create more problems then it will fix.

have you used seafoam? what is your experience with it?

 

I've only ever had good luck with it. Just make sure you add it to a full tank of gas. It should help. If you're reluctant, then just use some Heet to get rid of moisture.

 

Reviews are somewhat mixed on seafoam, but I've had quite monster success with it. I love the stuff and add it to a vacuum line. The problem with it (if i remember correctly) is it can temporarily increase compression as its burning when used this way and potentially create damage.

However, the method being recommended is using it as a fuel treatment, which dilutes it considerably. I doubt it'd have any of the possible negative effects that using it through a vacuum line would have.

 

If you add it to a full tank of gas you should be fine. Seafoam will clean your engine and stabilize your fuel which is what you need. I would suggest trying it, but if you're really that worried about it then just use Heet. Heet will remove any moisture in your gas tank as well.

That should give you all the info you need.

 

Thanks for the help. i may use it in just the fuel tank. Should i expect my car to run rough for the time it takes to have it work through? Also im at about a 1/2 tank, should i top it off and then put in a full can of seafoam?

 

I wouldn't expect it to run too rough since its just being added to the gas. Usually tossing stuff in with the gas has a very minimal effect on how the car runs (assuming it was meant to be there).

I'm not sure it matters if you top the tank off first or put in the seafoam first, they are gonna mix anyways. I'd just do both then run that whole tank of gas off.

 

Just fill up the tank and and a bottle of seafoam. It will stabilize the fuel and make sure there's no moisture. It won't affect anything major, so you'll be fine, but it will help a little at least.

 

I keep seeing more and more guys running on old gas and be fine, so I think I may just throw some Seafoam in my tank and drive the hell out of it. (It has a full tank of 2006, 87 gas).

Seafoam it and take care

 

My GTA was in storage for 5 years before I took it out this past October. I just siphoned out the old gas, put fresh 93 and a bottle of STABIL in there and she runs a hell of a lot better than she used to before storage.

I did however change the injectors. I had the Multec style injectors that were already going bad so they were changed out.

 

Wow, 5 years. was it stored properly? was there rust in the gas tank. thats my fear is rust in the tank.

 

The car was stored in a garage with a full tank of 93 with STABIL in it. STABIL only keeps the fuel fresh for 2 years so I pumped out the old gas. As long as you keep the tank full, very little water should build up in there. I had no rust in the tank and she runs really well after ironing out bugs such as rotted out suspension bushings.
