Type of fuel? Premium Unleaded or Normal - Benzworld.org

Whats the lowest octane I should use in my car?

Premium Unleaded is fkn expensive let alone Normal Unleaded. Normal unleaded is what I use, which is around 91-93 octane.

Too low or ok?

Obviously you have a different octane classification system in Australia than here in US. Here "premium" is in the 91-93 range, that is what you are supposed to use. No offense but if you can afford to drive a Mercedes you probably can afford the proper fuel.

I drive an average of 1200-1500km a week.

Premium Fuel is currently at $1.84AUD a litre (about $1.60US a litre)

+ 1. If you don't like and/or can't afford to pay for the proper fuel that is supposed to be used for the car, maybe it's time to buy a different car factoring in how many miles you drive in a year/month.

Consumerpi.... how much more performance are we talkin for the AMG cab vs. 430 cab ?

consumerpi · 07-13-2008, 10:23 AM

The difference is very noticeable.

On paper the HP difference is 342 vs 275 (67hp more).
1/4 miles times are more than a full second better at low to mid 5 seconds.

I don't notice a "lag" on the AMG car when I stomp on the pedal. The 430 has a bit of a lag when accelerating.

Let's just say that it's fun to drive again.

Wow. I know that lag ..it bothers me. There is a lag when u accelerate off the line and also when u punch it. I figured it was due to convertible top weight so maybe its not present in the coupe version ?

But your missing the point.

Ill use the Premium fuel if I have to.

But do I have to?

Normal fuel is 91 octane here.

Is 91 octane ok for the engine?

I see your point and quite frankly am not sure why you received such rude responses.

Yes, 91 Octane is just fine for your car.
I live in northern CA and our 'premium' fuel is only 91 octane. I have/ had zero problems.

Cheers.
