I know the tag on the filler door says to use 91 octane gas. But, does anyone use just the regular grade of gas, 87 octane, and if so does it make any difference. It does not make any difference in my other vehicles so I was wondering if it would be ok to put it in my passion. Would rather pay the $1.48 a gallon for the 87 octane than the $1.84 for the 91 octane.
"Would rather pay the $1.48 a gallon for the 87 octane than the $1.84 for the 91 octane."
If you do the math,
8.7 gallons (if you are completely empty?) @ 1.48 = $12.88
8.7 gallons @ $1.84 = $16.01
a difference of $3.13/tank?
You will get worse mileage/performance from 87 octane, so you will actually go farther on less gas using 91 (which is hard to find, so I always use 93?)
PLUS, if you have an engine problem, (and you have not been using the recommended minimum 91 octane), the dealer can make a case that is is a "Non-warranty" issue?
I have always found it false economy using lower octane fuel, as you get less to the gallon than with superunleaded.
I have had my smart roadster for over 4 years and have tried every sort of fuel, ordinary unleaded and superunleaded, and by the way ordinary is 95 and the super is usually 98 octane in Britain, not sure about how it is rated over here as someone has already argued with me that it is calculated differently over there, and don't want to get into an arguement I don't know enough about.
Anyway the long and short of it is, I have found one fuel that is the best for my smart, and it has been developed with Ferrari and Micheal Schumacher.
Shell Optimax 98 superunleaded.
I get great mileage from it so actually it is no more expensive than cheap lower octane fuels, and it makes my car go like stink.
The smarts don't have huge amounts of power, so why would you not put in the best fuel available to eek out every available horsepower.
Hope this helps.

Shell V-Power 93 [(RON+MON)/2] is the NA equivalent.

Based on past experience with high performance cars "requiring" premium, I used only regular in my '08 passion for 11,000 miles--except for 1 full tank of premium. As I expected, not a jot of difference, not in mileage, performance, in anything. I'm back on regular forever.

I think that covered it all.
This and more elsewhere. You can bet any part of your anatomy that for marketing reasons, Daimler AG, M-B Cars Group, smart GmbH and smartUSA LLC doesn't sorely grieve that they cannot honestly recommend** any less than 95 RON/85 MON/90 PON fuel. They know something (I'm convinced that I know what it is too) that too many people blow off.
**I am also convinced that (smartUSA's) Schembri's oft-cited on-air comment that using regular gas would do no harm was an ill-considered retort under duress.

Can you translate that into english?
Edit: Wasn't being a smartass... honestly didn't understand your point.
The car says it wants 91, I give it 91 (or 93 if 91 isn't an option).
If your doctor says "Take this 3 times a day" do you second guess him and take only 2? If your gym trainer says do 3 sets of 8 reps, do you second guess him? Why then do you second guess the car manufacturer when they go out of their way to tell you the octane to use in a car?
It's a few bucks a tank, at most it's a couple hundred bucks a year. You probably spend more than that on coffee at FiveBucks in a week. It's part of owning a high performance car, grow up and use what the little flap says and stop whining about the extra dime a gallon!
