What's the difference between Shell 91, Chevron 91 and Mobile 91 gas?

Question:
Does anyone know what the difference is, if one is better than another? From my experience, Shell 91 gas seems to make my car run real smooth but Chevron 91 seems to be more explosive. I haven't used Mobile 91 gas just yet. Does anyone have any experience or any technical expertise on these 3? Thank you in advance.

Which is better, Chevy Aveo or Scion xA?

First of all, make sure your car uses 91 or high octane. And if it does, it really doesn't matter what "brand" of gasoline you use. They are all the same.
But if you're car does not use 91 or high octane, DON'T!
Higher octane is not more explosive, it's less explosive than 87. 91 or high octane is made for cars that have high compression/performance engines.

Tire Pressure for BF Goodrich?

Gasoline is gasoline. The difference lies in the additives and detergents put in to the fuel. Very little difference between them. The benefit lies in the octane rating of 91. If you have a high performance car, use the higher octane. Otherwise follow the owners manual recommended octane. For example I have a 91 ford escort that I use for a commuter car. No way am I going to run high octane fuel, probably would melt down the engine, lol. But in my 99 ford F-150 Lightning I only run high test fuel. I prefer ExxonMobil fuel, but it is a personal choice.

Around how much would a 4-cylinder 1.3L engine weigh?

All the gasoline is the same, and comes from the refinery from the same pipe. Shell, Chevron, etc., supposedly put in a teaspoonful of a magic something that makes their gas special.

How do I calculate how many miles per gallon I get on my car?

"Techron" is one of those additives that somehow makes their product better.

If you are locked inside a car with the doors closed and the engine turned off, how long can u survive?

Personally, if I were them I'd say that my additive was Leprechaun spit and horse sweat, which would do about as much for performance but would get more notice on my commercials.
