Stabilizers are marketing BS, they can’t rejuvenate old fuel and they generally work by introducing an additional component that reduces the ability of the fuel (mostly the methanol content) to absorb water … however they rarely have a positive effect over all because they cause other problems.

Long shelf-life fuel is made in the refining stage. European standard E10 petrol can last a year or more if it’s stored correctly … I know this because I sometimes do store it for that long by accident.

That’s not correct. I have ethanol-free petrol for my chainsaw that has a shelf life of 5 years guaranteed (probably lasts longer, since that’s from the time of purchase)

It’s realistic that the most vicious people would hold on to the status symbols of before, and to indoctrinate those born after into the same way of thinking

Star Trek Spoiler

See Picard series 2 for that
