Long term fuel storage question
Submitted by beeroclock on Tue, 2025-07-01 13:16
Hi guys i have a tank thats full of 91 unleaded in the boat that i havent been able to use due to shit weather/work etc and it is now 2 months old. Weather doesnt look like improving much so its probably gonna sit there for longer. How long till fuel loses its octane or starts to gum up in the motor fuel lines. Should i add fuel stabilizer now or dont need to just yet - any tips appreciated

I've had the same fuel
I've had the same fuel sitting in the tank for 6 months or so and never an issue... but I do give her a start in the driveway every few weeks (Honda BF135) just to keep her awake..

Had it sitting a long time
Had it sitting in tank for 12 months without having any issues . Mine is inbuilt tank with inboard motor . As mentioned above it's good to start and run it every month or so to stop things gumming up
