Sorry, but I'm not sure i trust that.sciencefocus.com/qa/do-petroleum-products-petrol-and-diesel-have-shelf-life
I did a fair bit of googling about this when I first heard it. Most sources (the one above being one of the more reliable) seem to agree that petrol goes stale within anything between 2 and 12 months. I feel more comfortable believing that than a single wikipedia edit with no cited source.

Well, I agree that Wikipedia is an unreliable source - but "the website of BBC Focus Magazine" publishing a non-scientific paragraph* with no attibution or evidential backup isn't much better. At least with Wiki there's a *chance* it was written by someone who knows or cares ;)
If you keep it in a decent container that's not exposed to the air (ie so it can't evaporate or perform any sort of hygroscopic action) then it'll be fine for some considerable time. Straight chain alkanes are pretty stable molecules (think of how long they've been hanging about in the ground for), so if there's any "gunk" forming in there then you might like to ask the refinery when they added that's causing the problem!
*"more oily" ffs, that's not an explanation.
