Effective storage life of fuel in tank(s)

[GR1 Lurker Find all posts View Profile Close GR1]

I am looking at taking advantage of the cheaper end of the fuel cycle and filling both my tanks (to their 180L capacity)

As I use the Prado principally for occasional towing of my boat and van this might take me up to 3mths to use up before requiring another fill.

Will the unleaded 91 octane fuel start to go off over this period and cause problems or am I OK?

What is the effective storage life in the tank?

Was told that 98 octane was the way to go for long storage, found this.

My Prado is used for trips and towing the boat as well so I regularly have fuel in my tanks for a long periods of time.
I use 98 octane to keep the blower happy
I find 3 months is no issue, as a precaution you can add fuel preservatives to extend fuel life.
What also helps is minimal air in the tanks as well.

As for diesel being better for storage, yes as long as there is zero moisture otherwise you get algae growth in the tank and that can create major problems cleaning it out.
