Basically just wanted get other people opinions onit, much difference in relation to cost ?
-
I stick a tank full of shells V power in now and then in the belief it might help to keep the fuel system clean
-
In the Fazer it's hard to tell any difference, in the C90 the bike feels quicker and in the car I get around 3 MPG more and it seems a little smoother.
-
PERSONALLY I think the bike runs best on 97 fuel, I occasionally put in 99 which can make it feel nippier but is obviously the most expensive, but I really don't like using standard 95, it just doesn't feel great to me.
:lurk
-
I occasionally stick in some super and the only thing I reckon it does is make the exhaust bubble and gurgle more when I roll off the throttle.
If it's commuting, normal petrol, if I want to act all Billy Big Balls and sound good, super petrol :) [size=78%] [/size]

put a gallon in yesterday of some fuel i had lying around. riding in to work today the bike was noticeably more responsive, then i realised it was the trackbikes 98 ron in the can.
or it could have been the cold, denser air at 630am as well.

I use Shell's VPower in all my vehicles (99 RON)
All of them will run on standard 95 RON but I can live with paying a little more to help keep the fuel systems clean. The cars get a little better MPG, up to 10% maybe (but I rarely ever see 30 MPG anyway) but this doesn't cover the extra cost of the fuel.

huh, super+ is 7% dearer where i live..................so 10% better mpg would be a bonus, if i'm not mistaken!

This is true, but I'm not convinced that an economical engine will be able to take advantage as much. I have an MG ZS with a 2.5L V6 - this gets about 2-3 MPG better on its average of 28 - so it can just about justify the fuel cost on mileage but it's still expensive to run :P The RX-8 on the other hand I haven't tracked on normal fuel but it averages more like 17 MPG but I'm not sure if it will take advantage of the higher RON or not being a rotary engine. I guess it's possible but I still don't know as much about them as I do typical piston engines

I have an MG ZS with a 2.5L V6 oh dear!!!!have the butterflies started fluttering yet The RX-8 on the other hand I haven't tracked on normal fuel but it averages more like 17 MPG but I'm not sure if it will take advantage of the higher RON or not being a rotary engine. I guess it's possible but I still don't know as much about them as I do typical piston engines
the renesis motor has too many sensors to allow it to get near pre-ignition. my old 13b motor had 290 at the wheels and had to have super+. but once the boost got into double figures, the mpg went into singles :'(

Agreed, I reckon I save £36 a year by running the higher RON petrol and bike/cars defo runs better with it.
-
IMO "super" unleaded is just a con by the fuel companies to get you to pay more for something of questionable value. Any benefits would be minor if they exist at all.
-
I thought the bikes were set up to run on 95 octane fuel. :rolleyes.
-
Regular for me. My mad skills aren't good enough to notice any difference and if I want to clean the fuel system I go for a 10 quid can of carb cleaner.

The butterflies are still working as best I can tell :P Had the VIS motors out on Monday to check them over.
As for the Renesis, you are right, I've been reading some Turbo threads and that the pre-ignition has been mentioned... as the sell is going nowhere, I'm beginning to consider storing it and doing a long term turbo project with it :)

For a weekend / leisure rider this might be a good option if done regularly (part of general service and maintenance) but for larger miles I would have thought using a fuel with cleaning agents would be more consistent with maintaining the fuel system. Granted it's not overly complicated on the likes of the Fazer I suppose...

I'll also use a bottle of STP Complete Fuel System Cleaner over 2 tanks of petrol, probably once a year, to give the carbs a spruce up.
