Using the recommended 91 octane gasoline is your best choice. Using lower octane can cause fouling, miss-fire and detonation(pinging). While not too detrimental in the short term, this can cause premature engine wear over time. If you really need to save money at the pump, Try mixing regular or mid grade with premium in various ratios until you find a blend that runs well. Or Don\'t buy a car that requires premium.

Which octane is recommended for my infinti g35

yes....87 is perfectly fine and should be used all of the time with confidence. The higher octane fuels can sometimes help with a knocking engine but are mostly used for higher end vehicles.

Can an 2005 acura run safely on regular gas

The only reason to run higher octane fuels to to reduce the chance of (engine ping) or (engine knock).Try the regular gas(dont completely fill car) and take notice under hard acceleration if engine makes a pinging noise.If pinging happens then add some high octane gas to compensate for regular.Unless this is a modified engine the regular gas will not do any damage it will result in pinging and loss of fuel milelage.

Nockingnoise while the car is runing or stop

Are you putting regular gas in it? Sometimes a knock can happen when you don't use the correct gas. G35 are high performance and need 87-91 octane gas

I have a infiniti g35x and on the dashbroad it shows a message that the service engine soon? what does that mean and i just took it to the shop not too long ago

It means the computer has detected a malfunction in one or more of the numerous systems it monitors. There's no way to tell which code it has set without scanning it. Did you happen to get gas right before the light went on? The light will go on for something as simple as a loose gas cap. Check to make sure the gas cap is there and is tightened properly. If that is the problem the light should go off in a few drives.

I went and put unleaded regular gas into my 2005 Volkswagen Jetta drove home and when I went to start car again, it will turn on for about 5-10 seconds and turns itself right back off!! PLEASE HELP!!

Are you sure you did not put diesel in by accident or E-85? The VW will run on regular gas(not recomended) but diesel or E-85 gas is Bad for it. The E-85 can clog up stuff. You will need to drain and flush the fuel system, a new pump might help and all filters as well. Sounds like you got E-85 or Diesel by mistake. If this is helpful, please leave feedback. Thanks, SP
