About fuel octane indice

[meine dicke]

@Bonne Did you mention 'Avgas' to him?

...

You are aware that AVGAS is a leaded fuel?
What´s about your exhaust catalyst, if you have a newer Dero?

In the end I used ROZ 95 (E5) and there was no need up to now to take ROZ 98. Never used E10 and this will be so in the future.

@ Jasper. 'Hobson's choice'.

@ Rainer Avgas for old Triumphs as a treat.

@Zebulon. High octane and sympatico, excellent!

A lot of theoretical bla-bla (not that I would question the technical knowledge of those who think different).

Fact: my Varadero (and XLV750R) feel better. runs smoother, has a much better fuel economy and starts better on high octane (>98+ RON) fuel.
Frankly, I don't care if it is- or isn't the number of RON what counts. What counts, is my personal experiences and feeling; and from out over 300.000 km on motorbikes I will keep recommend high octane fuels. And if there was still leaded fuel available, I would even use it and recommend that too.

Fact: the exhaust of my bike shows a brownish-grey deposit which is a clear indication of an efficient (for as much as you can call an internal combustion engine 'efficient'... ) use of fuel and a clean 'burning' process.

Fact: you WONT feel any difference if you are used to use low octane fuels and only fill the bike up every now and then with 98+. The difference will be noticeable if you use these fuels for a (much) longer period of time.

I believe in the power of high octane fuel and I don't need to be convinced that it is rubbish. I have my own experiences with over 300.000 km and 4 Transalps, 4 Varadero's, 1 Africa Twin and 2 XLV750R's which are the proof for that personal experiences.

If you think otherwise... Well... its so easy. Keep fuelling up with 95+ or less. Its so simple as that... Just as simple that I keep recommending the use of high octane fuel on big V-twin motorbikes.

Bernard,

pls feel free in wasting your money, BUT have a look at this short summary:

Abstract
For several months, there are at service stations
Germany new varieties petrol to buy,
Shell (V-Power) and Aral (Ultimate 100), each 100
Octane. According to the manufacturer, this fuel helps
more output with higher
Consumption and improved acceleration.
The aim of the project described here was to use
comparative measurements reliable statements
about performance, acceleration and consumption of
be able to make new fuels.
It was found that none of the two high-octane fuels
relevant More power, more torque,
Consumption savings or performance gain
brings. The observed differences
below 2%, that is, on the measurement accuracy limit.
Regarding the performance of the reference fuel was
(conventional Super Plus Esso, 98 octane)
the fuel V-Power with 100 octane even
slightly superior. In the lower part load range can
at the high-octane fuels, a minimum
Consumption savings notice.

Guys,

Something must be wrong with my English... 
Its my personal choice which fuel or oil I want to use on my bikes.

And please... Stop that 'waste of money' dogma.  If it was up to saving money, you wouldnt even ride an expensive bike like a Varadero or Crosstourer but a boring Toyota hybrid.

[jackyork]

@ TP nothing wrong with your English or your facts or your suggestions to try.

@ Meine Dickie That comparison reads to me, like he is comparing 98 ron to 100. and still there is 2% improvement. What I'm saying is 95 Ron minimum and from a good source; just I find 98 better.

PS As previously stated, don't put leaded petrol in an engine with catalysers, it destroys them.

I think I am in agreement with TP. I use the best fuel I can afford for the best results of my engines, taking into account damage and servicing costs.
In my diesel Jeep, difference can be felt when using the top grade fuel  but because of the tax situation here, it is not worth the extra for me. A few years ago, it was more economical to pay the extra; price per Km being better but now it's more expensive. Still, I use only 'good' quality fuel; even in the lawnmower.

The Toyota comment above reminded me that I just bought a new truck ...last of the gas guzzlers!  4 liter V6 ...whilst I can    The Corolla is the compromise ...needless to say all run well on "regular" gas ...the Vara is the best! ...the truck is fun off-road ..The corolla is, well, fine for around town
Here's the trio:   Who else likes red cars?

No surprise that I'm in agreement with above...  I even use more expensive fuel in my (HONDA!  ) lawnmower and chainsaw: Aspen alkylate petrol. Alkylate petrols are the cleanest forms of petrol that is available on the market today, but they do come with a high price (even I know my boundries). Using normal premium unleaded petrol in small capacity engines without catalytic converters is damaging for your health, the environment and for machinery. Aspen alkylate petrol contains virtually no sulphur, no benzene and no aromatics.

U just need a red bike 

There is a red Varadero. Even from the model which was available in Canada... Nice Toyota (the pickup). Not all Toyota's are boring. Only the hybrids are...  And a Skoda Fabia Greenline. Which I drive... Can't afford anything else due to the expensive fuel taste of my bikes and lawnmower...

Hybrid low emission lawnmower

[Jyrays]

It consumes about 2 liter per hour, exhaust is not equipped with catalysator and will also make some dirty water

[jackyork]

@ SB a sign of the times that that type of mower used to have a wooden roller across the back instead off those plastic wheels.

@Jyrys I assume you mean two litres of alcoholic fuel per hour?

@Jasper. Red used to be a favourite of the car dealers as was known as 'Dog's Knob Red'. Yours appear to be more claret.

[Jasper]

Never saw a "red"  Varadero in Canada ...only the Barley Gold, Silver and Black. I used to have a CX500 and a little C70 (for winter) that were both red!   ...as usual I'm well "off-topic"    ...oh yes, and my recent Kawasaki KLR650 was red ....Ooops! sorry
 

[theiggy]

Well I will stick with the v power for the bike and 6% alcohol fuel for me on hot days.
