Regarding octane, I had a feeling that it took 89-91 US-style, but I
figured better to go too high than too low. 'Sides, with those d*mnned
one-hose pumps, if you fill premium and the guy before went low-test, in
the end you are getting 89-91!
Every newsgroup/mail list has its subjects that incite strong feelings
and ignite flame wars. I'm curious what engine oil people use,
synthetic (specifically red cap Mobile 1) vs. alternatives, but on other
groups oil has been an incendiary issue. How's it work here? Can this
be brought up?
Actually, is there an archive for this list? I can't find one with
And are there other detonators I should avoid triggering?

That worked on my R1100R, but so far, does not appear to work on my

I never add until it reached the bottom and I never fill it above the
1/2 mark. That will avoid over-filling

- - In the US, the reading on the pump is (RON+MON)/2. With the numbers
Steve has provided, that comes to 90.

compression ratio increases and thus requires higher octane.
89 will work fine. A simple test is to fill up with 2 or 3
consecutive tanks. Listen closely for pinging. If it pings, you need
To add further confusion:
Using higher octane uses more of your $$$ and doesn't give anything in
return. On the other hand, at 4 gallons/fill, and assuming
$0.10/gallon increased cost for Premuim, the $0.40 increased cost to
fill the tank isn't likely to break anyone's wallet. If Premium make
you feel better, use it.
I use both Premium and 89. It depends on how pissed I am at gas
prices when I fill.
As has been pointed out elsewhere, there is no knock sensor.
