are the octane readings on gas pumps accurate, or do i need to buy octane boost? my olds is set up to run on 87 octane and i was wondering if it is really 87 of i need to boost it some? thanks.

Your little car will run fine on 87. It has nothing to do with the energy stored in the fuel. It has to do with anti-knock agents added to the fuel.
Your little Olds is computer controlled, and has a knock sensor that the computer uses to control the ignition advance for knock control.

Don't bother with "octane boosters" they are crap! They say they raise octane by whatever points right? What they mean is the following...
regular 87 octane + octane boost = 87.5 octane.
Don't believe me? Look it up for yourself
You don't say what kind of Olds you have but unless it's been modified for performance or the manual calls for it you don't need anything more than 87.

It's really "supposed" to be 87 octane. Theoretically it should be tested by the state periodically to assure its octane rating. Some states do this, others do not. Ohio only checks pumps for dispensing the correct amount of liquid, not that it is the correct octane of liquid as advertised.

their supposed to be fairly accurate ,but there's times i doubt they are,i use a 89 octane with a booster in it,and it seems to make a lot of difference ,i have tried higher octane gas,but i do a lot better using 89 with a booster,id bet if you tested half of of what came from the pumps it wouldn't be accurate,you can try 87 with a boost to it and see what happens ,its not going to hurt anything by trying it,good luck on it.

the octane rating on the pump is actually an average of two different octane rating systems. this came about when one company would advertise the research octane number(RON), and another company would advertise the motor octane number(MON). the research octane number is the higher of the two numbers, and it would confuse people. so the government required that the gasoline blend in question be tested under both systems, and the numbers averaged. thus we get the formula ron+mon/2=the pump octane. this number is accurate as long as the companies gas blend remains consistent.

i have never heard of the low level octanes being below what they really are. i did however hear that the higher octanes are on occasion not what they say they are. unless u are experiencing a great deal of knocking, dont worry about it.

You don't need to boost it
