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...
