So I'm in NYC... and we have no gas, and the ones the govt sent are regular. IF I use regular, assuming I can find it, what are the engine knock/damage consequences or was infiniti jerking our chains with the premium requirement?

 

Nothing.. Just use it.

 

This ^
It's not going to kill your car for temporary usage.

 

It can be used in times when premium isn't available, but it isn't recommended. Your ECU will retard timing in compensation..

 

Word... if I can fight the hordes of angry dbags and get to it, I will. Thx!

 

Just dont floor it and get into high RPMS youll be fine

 

As mentioned, your car WILL compensate for the reduced octane (to an extent anyway). However, that doesn't mean you should shouldn't also modify your driving while using the lower octane gas. Your ecu will make due when presented with light to moderate loads, but may not be able to compensate for high demands. If I were you, I'd just go easy until you get some premium back in her. No jackrabbit starts or hard pulls up a grade, and generally avoid carrying heavy passenger/cargo loads. At any point, if you hear audible knocking or pinging, get off the throttle and reduce engine load immediately.

 

I've used regular for a good portion of the year I've owned my car makes no difference at all

 

Perhaps, since this statement defies all conventions and considerations for engine management with a high compression/high horsepower engine, not to mention the manufacturer's own recommendations, you should substantiate that claim a bit more. As presented, your assertion here implies there is absolutely no reason for using the recommended octane and that there is absolutely no consequence for doing so on an indefinite basis. Manufacturers have to contend with the negative impact on their sales from any additional expected annualized fuel costs (as required on the window sticker: http://www.nadafrontpage.com/upload/wysiwyg/FE_FAQs.pdf ) to operate the vehicle as recommended. Do you honestly think they would recommend premium fuel unnecessarily if it could negatively impact their sales?

 

My friend is bringing me gas from Connecticut this weekend... can't even get regular here anyway.

 

I have a good friend of mine that lives in NE PA. She can't find premium gas anywhere either. I also told her that 87 won't hurt for a bit.

 

Wow...it makes no difference at all. Are you talking about impacted fuel exonomy from using a lower octane? Ethanol is what kills fuel economy the octane doesn't make any notable difference.

 

I just use water, it works pretty good.

 

I think you missed my point. If the manufacturer recommends a higher priced fuel (ie. premium), then their annualized expected fuel cost will be higher than it would have been with regular.

As far as making no difference, I suggest you consider running two dyno tests on your vehicle; once while drinking from a tankful of premium, then again with.a tankful of regular and report back with any evidence that it makes no difference.

 

i only use reg now...use it..you will be fine
