Unleaded Or Super Unleaded?

[johnnyrod]

Redex? Jeez thats out of the ark. Some people say they get better mileage on super instead of regular unleaded, but some of the fuels are slightly higher density so a FI engine that regulates itself can use a little less volume because it's the same weight of fuel. As YC so diplomatically puts it though, road engines are made for the lowest type of fuel they're going to see otherwise it'd be a recipe for disaster. Anything much over the minimum octane number requried won't make a real difference, just like a pallet of Big Macs won't fill you up any more than one or two cos you'd never be able to eat them all.

SV handbook says the engine will run on 91 octane minimum. Its only that the "super" unleaded fuels have some additives that make it easier for cold starting that makes them worth purchasing, but only in the colder months

Speak for yourself, I've just dragged my Versys out of the garage so I can go for a tootle around and then pop to the launderette to dry last night's washing.

Tried it three times over same roads I seem to save about 2/3 of a ltr after 200 miles

LMFAO, sorry that made me crack up..... carry on

Calculating my fuel mileage every time I fill up, I find both my car and bike seem to give an extra 10% mpg using Shell V-Power, doesn't seem to be any difference with the other super unleaded fuels. If the price difference at the pump is not too great I usually fill them both up with Shell V-Power.

Not true, to get a accurate comparison you would have to find a pump on level ground, fill up from a completely empty tank putting the exact same amount in and in the same temperature so the fuel is the samw density, then run the engine at consistant revs untill its empty in the exact same climate (I had the same argument with a friend when he said his 1l polo was getting 65mpg )

its just a placebo effect, super unleaded only works in performance cars and even then i'd say the gains are only marginal or just to keep the manufacturers warrenty
