Exactly what is sounds like. A gas can full of alcohol. A normal mix is considered Regular unleaded but an extra strong mixer would be considered Premium.

A way of telling someone something tenderly, so as not to shock them or hurt their feelings. Best used when you are absolutely sure of something and you want to "drop a bomb" on someone. Can be used jokingly or sarcastically.
I can't be sure but....I think that was my grenade that killed you bro.
I can't be sure but....I don't think I used a condom last night.
If someone has done you a favour and you tell them that you don't know how to thank them, they could say: "You can thank me later" in the sense of that you can do them a favour later and help them with something.
If someone does you a favour and you don't thank them for it and don't seem grateful, they may say in a joking or sarcastic way: "You can thank me later" as a gentle or subtle (even unsubtle) reminder that you should be grateful to them.
If someone gives you a word of warning or tips to avoid you getting into a crisis and you think the advice is unnecessary, they might say: "You can thank me later" or "you'll thank me later" in the sense that although you don't take their words/actions seriously now you'll eventually realise that they were right and will be grateful to them - even if you're not grateful now.
