I should have stated, I recently purchased a car and the manufacter calls for 89 octane and I have been using 87

It always cracks me up when I see how many people believe the press. There is a reason that vehicles have specifications. These things are tested and proven by engineers that actually study and learn this stuff. I say use whats called for and save yourself engine problems in the future.
I think I will ask the weatherman if I should putt with my driver so I can save money and not have to buy an extra club.

It doesn't matter what type of gas you use. I saw a special on the world news a few months ago on it, and it said that even cars that tell you to use the better gas, don't really need it and you can easily run them off of 87 without hurting anything. The only thing is you might not get as good of performance, but that's only while you are using that gas, it doesn't have any long term effect. If you go back to the higher grade, you'll get the performance back (if you even lost any). About the only car that NEEDS the high octanes are Ford GT's or any other exotic sports car like that....

It will not hurt anything. If you have a newer high compression motor equipped with a "knock sensor" you'll gain a tad more power, the motor will run cooler and possibly get better fuel economy.
The knock sensor is a tricky device that manufactures add to retard the spark advance the instant Pre-ignition or spark knock occur. Any time the advance mechanism in and an electronic advance - retard ignition is reduced the power output is sacrificed.
Most motors will not suffer as the compression ratio and combustion chamber shape will not be affected by switching to a higher octane fuel.
Today premium chainsaw manufactures (Husquvarna, Echo, Stihl) call for a minimum of 89 octane gas. Pre-ignition in a high rpm 2 -stroke motor must be avoided at all costs. Aluminum pistons melt quite easily especially when low octane gas is mixed with a 50-1 with top shelf 2 cycle oil.
You will gain a ton with high octane fuel in the engine deposit catagory. Both of the undersides of your vales will remain cleaner as well as the combustion chambers.

Most engine computers can adjust for small differences like 89 to 87. I've never seen a car that called for 89..most are 87 or 91. If the car runs OK, feed it 87.

people say it`s a waste of money. I have done it in numerous cars . I run 93 and did the math and my gas mileage went up almost 3 mpg on highway. so ,why do race cars use higher octane ? Longer combustion burn factor for increased power. Try it and do the math and see if there is a different outcome. If you read up on the production of gasoline it is cheaper to produce lower octane. Maybe a little media influence from the gas makers

using greater octane is a superb theory and can get rid of your ticking noise, develop engine existence and decrease gas intake. How? gas is so flammable it somewhat is can ignite while this is not any longer meant too. One condition noted as "pinging" or "detonation" that's while component to the gas in a cylinder explodes at as quickly as as a exchange of burning at a persevering with fee like this is going to. those explosions reason a damn noise and would desire to finally reason injury on your engine, to boot decrease your gas financial device. yet another comparable condition is noted as pre-ignition, which produces a noisy knocking noise and can break an engine somewhat immediately. Octane retards the flammability of gas so as that it takes greater warmth and tension to set it off. In different words in case you utilize too low of octane on your gas then the gas is burning up too quickly on the incorrect time yet a greater physically powerful volume of octane will permit the gas wait till this is going to burn to burn. it somewhat is particularly lots impossible to apply too severe of a octane point to your engine, yet although, in case you haven't any longer have been given a pinging or pre-ignition situation then using a greater physically powerful octane point heavily isn't of any income.

No but why???
Not only does it cost more but most people burn the wrong gas anyway. Is it a power issue or something. Are you trying to get better gas mileage?
No it will not hurt anything but be sure it is not masking something else

No not at all, 89 is more expensive but the gas burn allot better than 87. Also it wiil give your engine a little more power.

No if the vehicle runs fine (no pinging) on 87 whey pay the extra money?

read this link your wasting your money.
If you feel your going to clean you engine. Wrong again.
If you need to clean your injectors run a can of sea foam thru the tank every 10000 save your money
