I have a lease on an 06 coupe...since i dont own this thing, was wondering if anyone in here has 'dared' to use regular 87 octane fuel on it?
What's the worst that could happen? knocking? pinging?

gas is so damn expensive on this car!!!

thoughts?

 

well the manual says in worst case scenarios use only a minute amount of 87 fuel and try not to accelerate hard etc...so i think it would be some knocking and pinging...imo i wouldnt try it.

 

its not that much more to use premium.

 

^+1... if u can't afford the gas then why are u driving this car?

 

Trade in your 06 for an 03 and use the extra money saved on premium gas, you cheap a$$.

 

I use nothing but 91 and even use 94 when I can get to a Sunoco but I still hear knocking at low revs. Any thoughts???

 

You will lag in performance and get worse gas mileage. You may save some change each gallon, but will need more in the end. Not worth it.

 

return your car and get a bus pass if you're worried about a few cents.........

 

Just read the manual the car comes with and that will tell you what gas to use.!! Besides premium gas is always the best for the g.!

 

buy a Sentra.

seriously, you bought a luxury sports car? why would you want to treat her badly? for shame.

 

My friend fills up regular in his Bmw e46. Nothing bad has ever happened.

 

you should have thought about this before you got the car..

 

my uncle does the same with his Benz E-class. Of course he an old timer who doesn't drive much. F that. I drive my G hard and want her to perform. Why go the cheap route?

 

This lady thinks it's okay to put Regular in her G35^

 

use 91+.
the cost difference isnt that large.
if you used sub-91 and got caught i would imagine you'd be on the hook for potential damage, despite the fact that it's a lease.
