Stale Fuel

[luvpsi]

hey guys i have been away in thailand for the last 6-7 weeks and have not started my car since about 8 weeks (rb25det with microtech and stock turbo. the fuel has been in the car for about a month or 2 before i went away as car is unreg and i only just start her and let it idle for a while until i can get her all sorted for the road. it runs rich so it normaly has that strong fuel smell however today when i started it it didnt have that strong fuel smell instead it smelt a little sweeter if you know what i mean. it also seemed to warm up a hell of alot quicker than i can remember. i maybe just being paronoid but could this be stale fuel.

You are paranoid.

3 months is fine. Not ideal, but fine provided the tank is sealed.

[luvpsi]

thought so just thought id check tho as i dont want to kill the motor cause it leaned out etc

just to be on safe side i might drain it anyway as it only got 1/8 of a tank

cheers for the reply

Just go and fill it up @ the servo.

Shell etc say upto 6 months IIRC, correctly stored (sealed), is acceptable.

yeah i dont know how well sealed the tank is as it is a tank from the 80's haha but ill do that just run down and fill up a jerry as i cant drive the car atm

my 86 skyline frequently sits around for months at a time without any fuel problems, knock never increases at all even after sitting for 3 months. but then again your tank was made by holden....

I let some fuel sit in my tank for over 12 months, no issues.

Dude I drained 2 year old fuel out of the BMW and it still tested for 95 I put a bottle of octane booster threw it and ran it in my daily

Same story here. Had a tankful of E10 100 in my S14 when I pulled it off the road 12+ months ago. Drained it all out to replace it with e85 and ran it in my daily with no trouble.

Years ago I bought an early Mini, it had been sitting in a driveway for 16 years. We started it on the fuel in the tank to get it onto the trailer (after spraying WD40 down the plug holes).

Then again, My mate wrote off his R1 due to stale optimax. Three months off the road it bogged down as he took off out of the mechanics driveway. He gave it some more gas and the bike highsided him. He 100% blames the fuel.

Like has been said, if the fuel system is sealed there should be no issue, but how do you really know how sealed your tank is?

lol @ blaming fuel...

So the moral of the story is, your fuel should be fine but if it does bog down a little , put the clutch in before you hard throttle it...

Take your fuel cap off, if it goes PSSSH it should be sealed. No psssh you've probably got an unsealed tank.

if you're paranoid, just drain it and use the fuel for your lawn mower and pop new fuel in

or a bottle of octane booster.... once off is not gonna hurt.

[luvpsi]

ill just drain it as its easier enough and i need it for my 2 stroke rc cars anyway so its not a big loss

[ARTZ]

Im not sick, but Im not well, da da da daaaaaa

better off with old fuel. octane booster just fouls your plugs real quick, even 1 bottle is enough to screw them sometimes
