Quote from: ohgood on July 23, 2013, 08:43:00 PMI asked where you get the higher quality gas ?

In the past few years I've moved around a lot, and each new city I move to I usually have to try a couple gas stations before I find a reliable one. It's trial and error.

Although I will retract my previous statement when I said I don't care what goes into my GS. I found one gas station it surely did not like, I won't be filling up there again.

Quote from: ohgood on July 23, 2013, 08:43:00 PMalso, how am I wrong ?

"93 octane is 93 octane, unless it's different methods of determining the octane, or different levels of ethanol."

That comment right there. All 93 octane is not the same. High quality 93 octane is not the same as low quality 93 octane. That's the entire point of my argument.

ok, first point - how are you testing the fuel to prove it's high quality ? seat of the pants ?



second point - see first point, are you testing it ?

Come on guys this isn't a scientific thread this is about how much your in tune with your machine and the little differences you notice and if alot of ppls little differences are the same we may see some sort of trend.

soooo, let's make it scientific. if anyone here can tell the difference between 87 octane and 97 in their gs ( most of us have/had one), by all means post up the double blind studies results.

since it won't happen, ill go ahead and call bullshit right now.

Because I have seen all the armchair scientists in all the other fuel threads so no lets not make it scientific. Science has been flogged like a dead horse on this forum.

no, it's easy. do a double blind test, you and your mates. armchair warriors regurgitating links and spouting about -possible- results instead of real results are why it KEEPS getting 'beat to death'.

Quote from: slipperymongoose on July 24, 2013, 04:14:28 AM
Well then instead of pointing the finger turn that finger around and do the double blind yourself and document the results.

sounds great !

are the people claiming that they can 'tell a huge difference' in 85/87/93/104 octane fuels going to participate in this and carry the bourdon of proof too  ?

i'll -GLADLY- run 85, 87, 93, and 104 through my bike with friends helping and keep it properly double blind.

how many of the proponents of 'higher quality fuels' or 'higher octane fuels' want to give it a go  ?

does anyone want to offer facilities or testing of actual fuel samples for actual octane ratings vs advertised at the pump, since we haven't tested that yet ? i don't have the know how, or i'd be happy to.

the whole point of these questions is not a character judgement, but to FIND FACTS and DISPEL MYTHS.

it's annoying as hell to keep hearing people regurgitate internet myths like "loud pipes save lives', 'race fuel', 'lay er down', 'thorough chain cleaning', and other messes.

too often a new rider will believe this trash and put themselves in danger, or worse, continue to spread the garbage to even newer riders that look up to them.

lets find the FACTS. who's game ?

I run the cheapest regular gas I can find, usually Wal Mart. In my 2011 Fiesta I've averaged 45.58 MPG for the last 15,000 miles (6 spped at). In my 97 Ranger (5 speed manual 4 cylinder) I've averaged just under 32 MPG for the last 5000 miles since I bought the truck used with 124k. The GS500E has averaged just under 62 MPG (all US gals) for the last 650 miles since I bought it. It's still lean under light loads but I'll probably take it off the road long enough to go through the carbs when I get the 89 roadworthy.

I wish I could get close to that in my Ranger... Can't figure out why it is so low, stopped trying... in my '97 Ranger which is also 5 speed manual 4 cylinder, I get 17mpgs... have gotten that since I bought the truck with 34k miles 6 years ago, now has 100k.  I also had an automatic 5 speed 4 cylinder '98 ranger for 7 years that got 23mpgs average, but I had tanks that I could pull 29mpgs out of... never broke 30 though... 

I never expected 30mpgs out of either, but 17? come on!  you'd think the manual '97 would do better than the automatic at least?

I did find that the timing was retarded when I replaced the timing belt on the '97... which probably reduced fuel economy, but would it make that big of a difference? Truck was owned by an old couple who kept it in a garage and used it for putting around town, so I guess thats why they had the timing retarded maybe... I'm really lost on it though...

Never really mattered where I filled up, cept when I got bad gas at Caseys in both of 'em... both trucks had same symptoms, ran like crap all the sudden, and real hard to start... didn't go there again...

- Bboy

Great make a thread and knock yourself out.

Knock light.

Do you guys use regular unleaded fuel of premium? I have always used premium the regular unleaded octane level is 91. Im thinking about using regular unleaded as fuel prices are always on the rise and im wondering if i would notice any difference?

You'll be fine with regular. The GS500 isn't real high compression and doesn't run any significant amount of timing advance, there's really no reason to use anything higher than 87oct.

Well my bike and car run like shaZam! with the cheap ass fuel so I use the non ethanol in my car and bike with none of the issues.

Brand don't bother me much either... although some of the dodgy little servos I avoid coz who knows what's floating in their old tanks? As long as it's 95 or higher octane my bike likes it... pings like a bastard with 91 in it. And no ethanol, don't trust it.

you have a pinging gs500 ?

If you have "knock" the problem is not the gas.......GS500 does not knock on regular.....unless some other problem with the motor..

Agreed

Copied from a previous post of mine:

My tale of octanes, gas knocks, and oil grades.

I had four 400-750cc Hondas I used 10W-40 oil winters and 20W-50 summers after they had some milage on them for the 230k miles I put on them.  When I got the 97 GS new I ran 15W-50 Mobil I full synthetic for about 50k miles after break-in.  After all 5 (4 Hondas and 97 GS) got 10-20k miles or so on them getting carboned up they developed gas knock in hot weather under load so I used mid range gas in them summers to eliminate the knock.  When oil consumption increased I replaced the more expensive Mobil I with the 15W-40 heavy duty aka diesel oil and then one hot summer day I inadvertantly filled it with regular 87 octane gas and it never knocked.  And it never knocked again for the next 30k miles I put on it with the 15W-40 oil.  My 02 GS has gone all of it's 90k+ miles on 15W-40 oil and regular 87 octane gas without a single knock.

Conclusion:  A 89-02 GS500 runs cooler on 10/15W-40 oil than on 15/20W-50 oil, no doubt in my mind.  Never had a 04 or later model with an oil cooler so I can't vouch for them but I would run the same in them myself.

I should probably add at this time that tire size had no effect on gas knock nor did the 15T front sprocket I ran on the 97 GS.   

By the way, peteGS was reporting it was his '82 GS450E that pings on lower octane fuel not a GS500.

The first time I tried to store a bike that had "Freddy Fast No Name" fuel in the tank was a disaster, 3 months later it wouldn't even "pop". My riding lawn mower couldn't run on the drool I drained from the tank. Not all fuel is created equally 

I don't really stick to a brand but I put "premium" in my tank. It's higher octane (which doesn't really matter) but the important point is it's way cleaner. If you take the premium fuel in a jar and take the regular unleaded fuel in a jar the regular unleaded fuel is far more dirty. This is more of a local problem and not a problem with the GSes.

The result of not switching sooner was it gunked up my carbs and gas tank over time because I didn't have a fuel filter.

I'm almost sorry for laughing at this... almost. put any modern untreated fuel in a 1/2 filled tank for three months, then come back and look at it. yeeouch.

you're telling me you can see dirt in unleaded, but not higher octane unleaded, from the same station ?

they're leaching fuel into the ground then, and you should call the epa !
