It won't really hurt your engine to bad but it will rob your power. Your engine doesn't compress hard enough to ignite all that fuel so there will be leftover of gas which will cause your engine internals to sluge up.
87 octane is fine, but it will not hurt if you want to use a different octane...
no it do not hurt
When I was little it hurt me a lot : (
they should have booster seats because you might get hurt only for 8 and down kids
that is your prefference,it should run fine on 87 octane. but higher octane will not hurt engine.
I asked the Lincoln Mercury dealer about this and they said that for optimum performance I should use a minimum of 91 octane but that lower grades right down to 87 octane regular can be used. When octane grades lower than 91 are used, the ECC (engine control computer) will automatically detune the engine to prevent knock although you will have a slight power loss. Using an octane grade lower than 91 will not hurt the engine.
87 octane should do fine. If you find it knocks a little then go to 89 octane. You can always use 91 octane, won't hurt, just in the pocket book.
They can go in the arm but they hurt less in the buttock.
only for a second =)
87 octane is good for 3.1 but if ya want to use a different octane it wont hurt.
No, as long as the gas is fresh and not contaminated.
It would only hurt if the car required 89 octane or 92 octane and you went to a lesser octane. Those cars are engineered to run on a higher octane. A car engineered for the lower 87 octane might actually see some performance improvement by going to a higher octane once or twice, because the higher octane will help to clean the injectors a "little". Not much though. Over all there is no real significance to using the higher octane. The higher the octane level, the "richer" or "heavier" the fuel is. So if the car is not manufactured for the higher octane, you will eventually cause carbon build up at a faster rate than normal.
