Gasoline Grades & Prices  

I also responded to a couple of his topics. In my area, the lowest priced gas station that I usually go to only has regular unleaded (87) & premium (93). In this case I would have to get half & half.

The car I'm using right now used to belong to my mother. That's the car that cannot take the 93 octane gas. It does pretty well with the 87 octane, but from what I understand, the higher the octane a car can use, the better if i want to keep my engine clean.

Before that, I used to drive this 1984 "poor man's caddillac" (really an oldmobile that usually needed caddillac parts) & I was only able to get decent performance using 93 octane gas. Well, nowadays, as comfy & sturdy the car is, the only way to repair it is replace engine.

either replace engine or get a new car I beleive what the guy on television said the other day they are trying to make cars disposable to just like most everything else I guess it keeps up we will have to go back to the horse and buggy.

Well, sometimes, if the car has a nice, efficient engine, using a higher octane gas than what you need would be somewhat wasteful in that you're paying more for it, & it's not necessary. Octane is supposed to stop the gasoline from igniting at a piston too prematurely by raising the required temperature needed to ignite it. This can also cause an increase of engine temperature, & cause more premature ignition of the gasoline, & well, doesn't seem to sound like a healthy chain reaction.

It's not you. Just that this one may have been too much of a technical question in which someone would need to really know about gasoline to give a good answer. This one discussion, I had tried to use it to get new people to sign up as my referrals, but I had learned a lot more about this from someone who is an airplane pilot as well as an expert in this.

That's great then.You are a nice person,and i want to answer all time at your question,but how you said it is tehnicaly or in a hard english for me.Take that advice and use a easy english for you get more responses...

I've been led to believe the same thing.

I don't think they are purposely watering down gasoline, as that is against the law. If the wrong person comes by & gets gas & discovers it watered down, well, I'd hate to be the gas station owner. However - if for some reason, the gasoline sits around long enough, it does seem to lose its potency. I call it "losing its poof" ...

If it's a gas station that you pay for the gas & fill up yourself, they most likely won't care. However, if you're paying in cash, it means running back & forth twice to pay the attendant for the filling halfway & then again to fill the rest of the way with the other grade.
