No, but you'd just have the fuel tank opening large enough that you can put in any particular handle. And in the end you didn't need Gulf saying this brand or that brand could buy gas, but not that brand. So while there were a lot of different handles before U842, they usually all actually worked with all the different brands and the gas stations didn't have to pre-approve the different cars to get gas there.

I've had a few gas tools and gas tanks which didn't have a gas port that was shaped for a U842 handle and yet I've still managed to fuel them just fine. I didn't need to get Shell's authorization every time I wanted to fuel a Toro.

I'm kind of amazed people think its a good thing for Shell to have the ability to say "no, that brand of car isn't allowed to buy gas here anymore". Imagine if Ford operated most of the pumps in the US and could just decide Toyotas could no longer get gas at the majority of pumps. Sound like a good idea?

Imagine if Tesla operated most of the DCFC dispensers and could just decide Toyotas could no longer get gas at the majority of dispensers? Oh wait, they already made that decision. Despite the majority of Tesla dispensers technically supporting CCS communications a Toyota couldn't possibly charge on most of those dispensers even if they had an adapter, because Toyota and Tesla don't have an agreement.
