Why super unleaded instead of unleaded
Discussion
Hey all!
I drive a Suzuki Ignis Sport and many similar Octane threads there's always people questioning WHY I use high octane. Well today indeed decided that super unleaded is the ONLY thing ever going in my car.
To lead up to why I must explain that I just completed my fourth year of Uni without a part time job. Therefore, having no money, am pritty much skint all the time. (Except for student loans)
Being so skint I decided on my last tank to save a couple of £ by using reg unleaded, and £40 tank for roughly 30L I enjoyed a good old 200miles... I kid you not, only 200 miles, when 30l of super I get roughly 280-300 Miles.
That is quite a lot of difference in milage, and unfortunatly I did not have as much fun due to the lower level of responsiveness of the car in general.
So to everyone who cannot see the point of putting super in my 1.5, there is a reason!
And for everyone who owns or are planning to own a Suzuki Ignis Sport, use super unleaded!

It does depend on your car being able to sense that it is using a higher octane fuel, or that it is tuned to be more efficient for a high octane fuel. Some cars have knock sensors that allow a car to advance the timing to increase the performance - some just don't have this. So it is down to specific cars if super really works or not.
Personally I don't think I could do a scientific enough experiment to work out if super gives me further miles or not as there are so many other factors involved, so I still think if I am not on a race track it is not worth it.
Just my 2 pence (saved from my standard fuel fill per litre)

Didn't see any discernible difference between super unleaded vs normal with the twin spark engine. Pretty much exactly the same mpg, pretty much exactly the same feel from the car in terms of performance.
Works for some engines, not for others. Mate who had an s2000 had to use super unleaded fuel.

A difference of 80-100 miles between super and regular?According to this: http://www.torquecars.com/tools/uk-mpg-calculator.... that's the difference between 45.46mpg and 30-33mpg.
Super can make the difference of a few mpg but >10mpg? Struggling to believe that tbh.

1. Why don't you have a part time job??? I drive a Suzuki Ignis Sport and many similar Octane threads there's always people questioning WHY I use high octane. Well today indeed decided that super unleaded is the ONLY thing ever going in my car.

2. Is your car turbocharged and/or tuned only for superunleaded? If not, I don't believe you'd see such a difference. Road conditions, weather and driving style or something wrong with your car are far more likely.

Doesn't really explain why though.
Why does it need super, when a litre bike will make 170+ bhp per litre on normal unleaded.
Seems an odd design decision as it reduces the potential market.
In simplest terms bikes use high revs to make power, cars use more torque at lower revs. Engines tend to become knock limited at high BMEP numbers (analogous to torque per litre) which I suspect bikes don't get to, even when they're putting out massive bhp/litre numbersWhy does it need super, when a litre bike will make 170+ bhp per litre on normal unleaded.
