    Does anyone have fuel economy data that they have gotten when running their bike on opal fuel compared to Premium ULP and did you use any additives or booster in the Opal?

    Every time i’ve had to use it I’m down at least 15 % dropping from around 20kpl to mid 16s

    I have found that in "slowish" dirt track riding that there is minimal difference. (4 - 5 litres per 100km) Running 2500 -3500 rpm rather than fully revving out helps a lot. On the F800GS this equates to 70 - 85 km/hr in 3rd or 4th gear.
    This could of course be radically different on bikes that use 98 or need to rev high,

    I have no personal experience but I am aware that Orbital engineering did a report for BP I think in 2006 comparing ULP with Opal.

    Have used Opal often both in DR650 and also R1200 GS (LC and oil head) without boosters or additives. Never kept track of the stats but didn't notice much (if any) change in performance. Ive had my R1200 LC 'detuned' to run on 92 Octane and never used Premium. Seems to pull OK IMO.

    Gday.
    Ran a tenere 660 and a ktm 690 from Warburton to Wiluna. Only noticed the exhaust notes were softer not such a bang.
    Milage we are getting about 5.5ltr to 100km and there wasn't much difference with opal.

    I did a lot of miles on opal last year with the WRR, no difference in fuel consumption, very little difference in performance... but, I got some out of drums at Ilkurlka this year that seemed a little dodgy, the bike was noticeably low on power...

    I'll be my usual contrarian self again and go against the grain - my experience with Opal is that I get 5-10% BETTER fuel economy than with normal fuel. Getting 30-35km/l on a G650 Sertao on the GCR.

    Mind you, overall it works out more expensive because OPAL ain't cheap to buy.

    Jim, some bikes also have a lo-octane setting for poorer fuels. Some KTM's with Kokusan ignitions have the setting, switchable, and BMW GS 1100/1150 twins have a coding plug for lo-octane. I dunno what you will be riding but it might be worth investigating.

    I definitely felt the difference on the 950Adv with the Opal and once I disconnected the low octane ignition curve connector it improved.

    I sincerely doubt that you will find much difference than using the usual Unleaded 91, considering that the only difference is in the aroma... It is exactly the same as Unleaded 91 not the Premium 98, just designed not to be easily sniffed...

    Biggest difference is that you usually have to ride all the way out to a desert to get it . Using much more unleaded than just going around to the Coffee shop .
