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.

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....:nyaanyaa:

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?

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

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
