Can i put a gallon of 87 octane?
 

Over here in New York were having a bit of gas crisis and i have a gallon of 87 octane in the garage, its maybe about two years old. I was wondering if i could use it for the FRS if i really have to or should i just pray that i never have to use it?

Thanks!

the short answer is yes. but you will encounter reduce performance.

now if you can get your hands on some octain booster, that could help.

if you do add 87, make sure to take it easy on the engine.

I'm with you man, I threw 87 in, im not beating on it so it should be alright... no signs of any issue yet.

You can but, but until that gallon is done drive EASY. If you can avoid uphill driving on severe inclines. It's only a gallon it's not like you're filling your tank with it so you'll be fine. Just know that preignition is no joke, I've seen holes punched through pistons because of it. Like wu_dot said, if you can get your hands on some octane booster use it

be wary of gas that is over 6 months old and contains ethenol. That breaks down and will foul your engine. Sta bil or other products will allow you to store it.

I would be more concerned with the fact that it is 2 years old than I would with the octane, make sure there is no dirt or water that could have gotten in from moisture build up over the years.

the higher octane fuels will be less resistant to combustion under compression. you won't find the knocking that used to be the case with old engines running lower octane than they were designed for, but you will lose a few horsepower. Also, I don't believe octane booster does much, if anything at all, at least from the articles/tests I've seen.

Say hello to probable gunk and a reduced lifespan for your fuel filter in addition to the knock issues you will likely have.

I would do everything in my power to avoid it.

Use it in your lawnmower.

if its just 1 gallon i think it should be okay. perhaps run some gunk cleaner like techron later would help with gunk buildup.

How much would you save? Is it worth it? If yes, use it on you. :bonk:

Alright, thanks guys.

I think i'm going to let it stay since its over two years old. Though a lot of gas stations are only selling 87 octane only as well, if i have the patience/balls to wait in line for hours to get some gas. Can't even get full tank, can only do 20 bucks...

Frankly, a gallon can get me to school and back and considering the fact i personally know people who wait on line for gas more then 4 hours and not even get a drop of gas...its pretty risky. Theres tons of cars around of empty gas stations just because they run out of gas waiting...its quite nuts.

If it were fresh 87 octane sure. 2 year old, without stabilizer, no way!

you'll be fine, just dont go beatin on it...

Don't let that gas anywhere near your car! As others have said, it's not the octane that's the issue, it's the age of the gas.

Definitely the face of good advice. :rolleyes:

I dunno dude, seems questionable. The octane isn't correct and the age is making it questionable.

It's like my car is meant to eat prime rib, and I gave it frozen hamburger patties....from two years ago. It'll take it, but you might not agree with the results. I'd hold off on it and procure some correct fuel for my lovely.

People already get issues with Californias 91, I wouldn't put 87 anywhere near the car.

If you have to use it, make sure to dilute the hell outta it with some fresh gas (preferably premium).

Your engine will explode.

Because of the age of the gas I think you made the right decision.

After two years it's not gasoline anymore.

I'm in the same boat. How bout those gas panic line dwellers huh?

If you drive to NJ or CT there's plenty of gas and no lines, so I hear.

As a Toyota technician I would say no do not use 2 year old gas EVER. If it is stored in a metal gas can rust will form and contaminate the gas and if its in a plastic can it will eat away the plastic and contaminate the gas. Now if you put new 87 grade gas you will be fine as long as you drive it safely with light acceleration due to timing changes which will take it out of tune. With the circumstances in NY it will be fine until a higher grade gas comes available.

No dont put 2 year old gas in your car.

I understand NY are going through hardship. But we are talking about 1 gallon of old 87 gas. What if something went wrong? The best advice is avoid it. Be safe than be sorry. Get a ride from somebody or take a bus/cab if you can't get any gas.

Here in NJ I had no choice but to put in 87. Was only 2.5 gal but still felt cheap (no one has 93) but I didn't notice a bit of difference. 13.2 gal tank in the FR-S. A SLIGHT mix of 87 isn't going to do a damn thing and anyone else here saying "Oh now you just brokedededed X,Y,Z!" is a buffoon IMO. Could be worse, you could've gone to Hess and had them fill your car up with diesel instead of unleaded like many other unfortunate souls.

On the topic of the AGE of the gas, I'd avoid it.

NJ has tight rules atm on gas. Odd/even gas rationing still going on and most, if not all, stations are out of 93 and only getting delivery of 87. Sucks but what can you do? Drive 3 states away? Makes sense to me. /sarcasm

Where are you really going to get comfortably on one gallon of gas? Sell it for a surcharge to some other sucker and use the money to buy booze for your long walk home from wherever you're going.

The 2 years is a problem not the octane.

Pour some of it out where you can look at it, then look at the color, and then report back if you would feel comfortable using it, lol.


In a gas crisis, use as much fresh 87 as you please, but I would NEVER touch gas that's more than a few months old.

does 2 year old gas even smell like gas anymore? i drained some gas outta a old harley and it was a darker yellow and smelled nasty but it was probably older than 2 years

For those looking for premium, check out this link:

It's limited to HESS but at least they tell you how much premium they have on hand. Make sure its above 2,000 to be safe.

If you use that 2 year old gas all of your plants will die… Do you want to be known as a plant killer? DO NOT USE THAT GAS IN YOU NEW CAR!!!

Gasoline crisis ? how bad is it in New York ? the gas price just dropped to $4.15 from 4.60+ here in San Francisco last week. I wouldn't put anything else below 91. I wish we had 93 here in California. And 2 years old gas to something you want to keep away from a new sport car.

When i posted it, it was bad, really bad.

Now its almost back to normal, its not that hard to get gas.

You guys can let this topic die now. :lol:
