Unleaded Or Super Unleaded?

I talked to my dad about this at lengh, well he has worked in the oil industry longer than some you have be alive...

He only put in his sports car, as it simply got a higher mpg than putting standard 95 RON which I stick in my bike. It didn't make the car go faster, or increase the BHP or anything like that. I really think many are getting a beliveed effect. Its like people I dived with said, oh Nixtrox taste better, eh?

I'm mean really what you do with a 1-2 bhp gain anyway? Like the vast majoirity of us would ever notice, me being one of them.

Well I guess you can be like the people I have dived before, it makes them feel better, but they will never understand why they are diving on nitrox fully, scary really.

Isn't unleaed fuel one of the big cons any way? Lets put a cancer casuing agent, into the most used fuel in the world, nice one.

MON (motor octane number) is normally typically 7 numbers lower than RON (research ON), doesn't often vary much from that. In the US it's normal for the average (RON+MON)/2 to be used, sometimes referred to as "pump" octane number because it's usually quoted at the filling pump.

91RON as cited in the handbook will be typically 84MON and around 87 (R+M)/2

In reality you only need to use one system for general purposes, once you get used to that particular rating.

There was a review recently in BIKE or RIDE magazine, comparing Shell VPower, Total Excellence and BP Super or what ever its called!

And it made no difference at all apparently. A Tiny bit but not enough to explain the extra cost.

Shell V-power in the winter, to help with smooth, fuss-free cold starting and intial running until the engine is up to operating tempurature.

Else 95 RON is more than enough...Suzuki claim 91 RON is the minimum grade of petrol to put in the tank

FWIW, I did feel a notice between V-power and normal unleaded on the transition from shut throttle to just a tiny whiff of throttle - shell V-power makes it a little smoother. I don't know how much of that is in my head though

oxygen is a diradical and is carcinogenic...as is the UV rays from the sun reaching us here on earth

far more carcinogenic dangers and feul additives

i thin its all in the mind because when you put in v power your tryin to get the best mpg out ya sv then ur watching ur speed i mean who cares what mpg ur geting when your bombing round the lanes and up and down motorways over 100 lol u dnt get any mpg at 11000rpm

I care, because I commute (and rarely get to 8000 rpm, let alone the limiter...) I'm gonna run a few tanks of 95 RON when the weatehr gots mroe agreeable, and then I'll do a test. 95 RON vs 99 RON shell fuels. For shiggles, I'll also do 95 RON + Silkolene pro FST (carb icing treatment additive).

Incidentaly, I dont run V-power for MPG...I run it for ease of cold starting, and also because I beleive it to make the engine smoother on the off-on throttle transition, and because I understand it to have some extra additives to keep the carbs and engine a bit cleaner

Again, could be wrong on all those accounts

its all good fun

I use super in the car and I get a little better mileage, but its here and there as to if I am saving any money. Does not seem to make any difference in the bike
