Maybe so….but I bet some newer bricks, other motos, and TB’s Hardley Ferguson riding neighbor does…..

Hah - that's funny, but you guys don't know my neighbor Jeff. He's been a REAL biker since the 60's, (not yer investment banker make-me-wanna-puke weekend warrior HOG member poseurs). Grease and oil come out of his pores, and the idea that he's have a cat on one of his vintage tractors is pretty hilarious. But like I said, you don't know the guy. Our neighborhood is full of colourful characters like him :giggles.

If you shot a 30 06 at a 45 degree angle, could you hit his house. :giggles

Mebbe could with my 7mag.

I am finding that pretty much all the Chevron in NM has 10% ethanol, regardless of grade :/
BUT - the Phillips station on the south end of town has 90 with ZERO ethanol! Put some in the R75/5 the other day, seems a bit more peppy. Will try in some in Chili Red soon...

Monsoons are here, driveway gettin' kinda soupy.

Question for all of you,

You guys keep talking about running premium fuel and yet the book that came with my bike states I should use 89 octane. What gives?

TimTyler · « **Reply #28 on:** July 17, 2012, 05:48:41 PM »

The BMW sticker under my seat suggests "91".

argent brick · « **Reply #29 on:** July 17, 2012, 06:31:25 PM »

So, it appears that I need to get off my fat ass, go down to the bike and take a look.
I have been hearing that the gas is the same, just the math is different.
When did they change the way octane is figured?

frankenduck · « **Reply #30 on:** July 17, 2012, 06:37:02 PM »

K1100s came with a sticker behind the gas cap that said 91.

johnny · « **Reply #31 on:** July 17, 2012, 06:46:04 PM »

yawl...

octane is figured in the usa by the ( r + m ) / 2 method...

my heaps ping on 87... sometimes ping on 89... go like a moe on 91+... especially when i score the no ethanol... then its pure yeeeeeehaaaaaa... 93 no ethanol is like riding a magic carpet...

I always put the cheapest stuff in I can find (87) and my K75 runs great on it.

racinrich · « **Reply #33 on:** July 17, 2012, 09:12:07 PM »

I agree with johnny 91 no ethanol got 46mpg,93 with 10 percent ethanol 40 mpg.so up to cheeseland for the good stuff I'll go.as for additives a product for pros is BG all others are snake oil purely sold for profit. Pure-gas.org shows no ethanol stations around usa.

orforester · « **Reply #34 on:** July 17, 2012, 09:50:31 PM »

I use only 91 or better, never tried anything else. Pure-gas.org is a great site, I check it everywhere I go to find the no corn gas!

me and jumpin jimmy b both got 46 mpg last wednesday on the 91 no ethanol... i got 30mpg on 6 month old 89 ethanol on the same moto just 3 weeks before... obviously that 6 month old gas lost lotts of it energy...

Corns good for eatin' but sucks and a gas additive. My mileage goes in the crapper when the K gets fed corn.

As far as knockin' and pingin' go, no worries up here at 7,000' no matter WHAT you put in th' beest, octane-wise. But in the manual for my '92 K75, it suggests 91. 90 no-corn makes all my whips run wicked strong. Been considering going out to the airport for some o that no-corn100LL. That should wake 'em all up REAL good :2thumbup:

argent brick · « **Reply #37 on:** July 20, 2012, 01:09:49 PM »

Like I wrote before, manual states 89 octane for my 1995 K75, BUT the tag under the seat says "91 octane".
Why the difference? Looks like "91" fuel for this brick.

TimTyler · « **Reply #38 on:** July 20, 2012, 01:41:43 PM »

Perhaps the decal is based on German ratings and the owner's manual is US?

In Germany, a 91 RON octane is considered "standard", probably the lowest grade available at the pump.

In the US, (as mentioned earlier in this thread) octane is MON + RON / 2.

If your basic US gas has a MON=87, then rated in association with standard 91 RON yields a 89 octane (M+R/2) at US pumps.

So German 91 = US 89. Super-fun chart at http://en.wikipedia.org/wiki/Octane_rating#Examples_of_octane_ratings

Thanks for the info Tim. I think you may be right with the German/US idea.
I try to burn Chevron or Shell in all of my gear (including backpacking stoves).

The summer is half over and I have only put about 200 miles on my brick since I bought it.
I need to ride more.

TimTyler · « **Reply #40 on:** July 24, 2012, 11:30:20 AM »

I didn't notice this before, but the label under my seat specifically says: RON 91.

flying brick · « **Reply #41 on:** August 01, 2012, 08:35:33 AM »

So consensus is, no performance/mileage or engine longevity benefit to using medium or high grade fuel? 87 octane (here in North America) is the best?
I have tried 89 with no apparent difference. Any feedback on 91? My brick runs and idles fine, but wouldn't it be nice to increase fuel mileage?

Modern day petrol is ch!t, enough said.

Spend the extra dollar per tank up is the mantra.

Thanks for the reply Gary....so, in a nutshell the Quality and QC has slipped over the years, and ya get whatcha pay for now? I have 38,000 miles on the odo, and would like to feed it what is best. Any first hand experience with going up from "regular" to "premium"? We both live in the northeast, so weather, fuel, and riding conditions would be similar.

In Australia we use the RON system and I always run my K1100 and especially the K75 on the highest grade I can get which near home is 98.
I dont want any detonation and considering the compression ratio of 11-1 the lower grades will give some. The best reason of all is the Nicasil bores and detonation do not coexist happily one little bit. In my opinion consistent use of low grade fuel is the main reason that the nicasil bores fail and I have been fixing and building engines for a long time.

Better mileage, less pinging under full wicK factor using premium.

My whip likes Shell brand 93 petrol. Sunoco for some unknown reason burns funky.

Course, where you actually buy the gas is another story. Newer stations/pumps tend to have a better filtering systems.

If all else fails,buy a bottle of Chevron tech cleaner concentrate for occasional dosing.

Part of the problem is the 10% alcohol,read less bang for the buck. :hmm:

Any of you brickers happen to know what Nitrogen does for for cleaning purposes ? Shell markets that fact BIG time, clueless about the actual chemistry.

Waiting impatiently for the damn fog to clear, planned on a ride but the mountain roads are totally "socked in" presently.

Well, you are a wrench, so I will start using "high test" and leave it at that. My original reason for asking, was that there seems to be a bit of confusion between Boxers and bricks in the real world. All my boxer friends tell me that they were built to travel the globe, and hence, needed to be designed to handle the worst and best fuels out there. It begs the question, it that a myth? or a "tweek" by BMW for dual sport or "adventure" models only? or is that also a myth. I have rebuilt a few bikes, but they were simple HD and vintage Triumph engines, so in IMHO I am a Luddite compared to real mechanics. The "simple" regular task of cleaning or replacing an air filter on my K is mysterious and puzzling to me...even with the factory manual, so rebuilding the engine is not high on my bucket list.

TimTyler · « **Reply #47 on:** August 01, 2012, 09:41:41 AM »

I won't buy high octane gas for the bike from a station that has one hose on a pump offering multiple fuel grades.

I figure there's probably at least two or three gallons of whatever fuel the last guy bought pre-loaded in the hose and pump plumbing, and I'd likely be wasting my money.

flying brick · « **Reply #48 on:** August 01, 2012, 09:45:09 AM »

Wow! One pump three grades? :yow I can't remember the last time I saw one of those! ....1960's ? Where do you live? LOL!

TimTyler · « **Reply #49 on:** August 01, 2012, 09:52:39 AM »

Many of the newest gas stations are setup like that.
