Premium unleaded only !!
With fuel prices for premium escalating everyday, you might be tempted to use a midgrade fuel or God forbid regular unleaded. But be warned... Even with the high fuel prices only use premium fuels. The vehicle was designed and built for performance so anything less is not recommended. The lower the octane the more detonation will occur in the combustion chamber causing quenches which is combustion before the piston reaches top dead center, this will retard ignition causing low power output and with time excessive carbon build up on the piston tops and cylinder head which can lead to rough idle, long cranking time during start up, knocking noise in engine on light throttle acceleration and sometimes knocking when engine is cold. Some cases can cause oil consumption due to sticking piston rings from carbon. Carbon build up is not covered under warranty.
Some people say gas is gas..... If that is true then why do Motorsports teams use special racing fuel? And why do gas station have different grades? Wouldn't it be in the manufactures best interest to tell customers they can use regular gas?
I watch people constantly use regular fuel in vehicles that require premium every time I'm at the pumps... Very sad.

+1 - I laugh when people say theres no difference in between regular and supreme.
At the end of the day, you drive a $70k car, don't cry about putting premium gas in it, and if you do, maybe you should think about downgrading.
The difference between getting 89 and 93 is probably only $3 on the fill-up anyhow.

Most modern cars will adjust their timing to mitigate most of the factors you posted, I know my wifes infiniti does so, sounds more aggressive with lower grade fuel, but has slightly less power, less efficient, and fewer mpg, so in the end, its a wash, since you end up filling up more. The vehicle can use any type of gas, the factory manual says so (but recommends premium).
Again, not sure about out cars, but as Pat said, the difference during fillup is minimal between low and high grades, 3 to $4 in the grand scheme of a $70 fill up is not really that noticeable, unless you keep track of your fill ups, and look at the larger number over all after time has passed.

There is nothing wrong with complaining about gas prices dude. I agree with the argument on fuel efficiency. But NOT on gas prices.
I don't care how much money you make, paying $70 to fill up your car is BS! I own a boat to, it used to cost me $600 to fill her up, now it costs me $800! Guess I cant afford that either right? $7, $200...$10,000... Its money in my pocket, not theirs. I dont think any of us are rich enough to just throw away money or I think we would be in another part of this forum.
Its funny how throwing out dictators across the world ends up costing us "Free" people a buttload of money.

You guys should be glad you don't live in the UK. Super Unleaded (97~99 RON) is currently up around £1.40 per litre (and rising...!).
Roughly translated, thats around $140~$150 USD for a tank full.....
Still, I absolutely refuse to give in, and will happily keep filling up my baby with the good stuff..............even if it does make me wince a little....!

anyone who *****es about paying $4 extra or so on each fill up, shouldn't be driving ANY AMG to start with. Hell theose are the guys who normally drive Prius - and other econoboxes.

Actually the cost savings on a prius sucks. You can get the same fuel economy out of a Corolla and pay about 10K less for the car. By the time you see the cost savings on fuel after the 10K you would have sold the car. Prius's are for the tree huggers so they can not pollute the earth. Thats why all the famous people drive them.

Considering what we pay! We actually have it good as compared to say Europe or Australia. Their paying about twice as much, but of course their jungle juice has a higher octane rating then our kool aid.

Im not here flaming guys C63 owners - as Im sure some people streched to get this car (as I did with my M3 wen I was 24), but I was prepared for the worst. $4 gas prices arent unheard of, we've had them as little as 2 years ago.
Back to the point of the post - the difference you pay in supreme gas versus regualar isnt worth the potential to damage the car - or even worse, underperformance.

Like I said, it all adds up. Wait till the summer when gas will cost $4.50- $5.00 a gallon. $80-$90 to fill up your car. With my boat one weekend of fun will cost me about $900 in gas when it used to cost me $640. Thats $1040 a month extra just on fuel costs. Never mind the heater on my pool and everything else that uses gas. I pay upwards of $2800 a month in gas last summer. Ill be spending probably $1500 more a month this summer due to gas prices.
If people don't think that's a lot of money on this forum then I guess I should sell my C63..
If all you got is your C63 then yes, $7-$10 more a fillup is nothing to complain about... I agree. Sadly, that's short sighted if you own anything more than that.

I lived in Hawaii for 4 1/2 yrs, and we always had high gas prices. As you know Hawaii has no oil refineries, and fuel had to be imported. I would watch the news, and hear about gas prices on the mainland, and I simply said to myself "And there complaining, they need to come here".

I grew up with trucks and muscle cars. Actually one of my first cars was a 76 GMC Jimmy with all wheel drive. I think that thing got 7-8 miles a gallon lol.
The gas mileage of the C63 sucks, but when you blow the doors off of one of those hat on sideways, wife beater wearing, steroid muscled douches in an SS Camaro.....it makes it all worth it

I don't get bothered too much about the gas prices as I just tell myself that's the gas mileage I used to get in my Explorer Eddie Bauer. If I ever doubt myself, I just use my right foot to convince myself that everything is A OK! lolz

I'm paying 1.25 per liter in Canada. That is 3.78L = 1 US Gallon = 4.725 per gallon. Seriously in the grand scheme of things its just a few bucks more per tank...hurts but gotta pay to play.

For the record, I used to have a hybrid (The Toyota Camry variant, not eh Prius)
Based on the fact that the hybridized versions of the various vehicles (the Prius being the exception as it is a hybrid only model), have around a $5000 to $10000 premium over their regular versions, and based on a standard 12000 miles per year, the various hybrids would take far longer to recoup any savings based on the cost of gas over the life of the car.
At one point, there was a Honda accord hybrid, it was V6 based, but it only got about 3 to 5 mpg more then its regular counterpart, and cost $10k more. The emissions were not exactly stellar either, which is why it was only sold and built for about 2 or so years.
In fact, go read this.. http://www.greencarreports.com/blog/...know-which-one
The only hybrid that actually has a positive ROI, is the freaking Mercedes S400 hybrid...

Don't know what manual you are reading from but "Only use"
does not mean "The vehicle can use any type of gas, the factory manual says so (but recommends premium)." to quote you.
unless you construe recommend to mean only
In which case I recommend you reread your owners manual.
Mercedes is not Infiniti last I checked
Fuels, coolants, lubricants etc.
396
Fuel requirements
Only use premium unleaded gasoline. The
octane number (posted at the pump) must be
91 min. It is an average of both the Research
Octane Number (RON) and the Motor Octane
Number (MON): (RON+MON)/2. This is also
known as the ANTI-KNOCK INDEX.
If premium unleaded gasoline is not
available and low octane gasoline is used,
follow these precautions:
Have the fuel tank only partially filled
with unleaded regular gasoline and fill up
with premium unleaded gasoline as soon
as possible.
Avoid full throttle driving and abrupt
acceleration.
Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded with a
light load such as two persons and no
luggage.
Do not exceed2/3
of maximum
accelerator pedal position if the vehicle
is fully loaded or operating in
mountainous terrain

I was actually talking specifically about my wifes car, not ours. What I did say was that it is possible to use non premium gas, without destroying the engine, as the engine will adjust. But I did not say that you should do it all the time, just that it is possible, more so in an emergency then anything else, which I probably should have stated.

Makes me made too that we have to pay higher prices when the cost of extraction and refining, transport have not changed as dramatically. Just political instability, that could lead to a disruption of supply. These spikes in price are just pure profit for the oil producers as higher costs are not really incurred during these periods as I mentioned.
Anyway I look at gas as an entertainment expense not transportation.
