How many of you can run 87 Octane with good results in your bikes?

2kMarauder · 01-03-2006, 01:32 PM

I do. That is all i have ever run in my 2000 Marauder800, and no problems.

Uechi Kid · 01-03-2006, 02:07 PM

Suzuki recomend 92 for the M95 so that's what I use.

Marauder02 · 01-03-2006, 02:16 PM

Ride '02 Marauder and use the 87 octane. Stock carbs, debaffled exhaust. Never have any probs.

S83 · 01-03-2006, 02:22 PM

I get spark knock under load.

QuacktheDuck · 01-03-2006, 02:24 PM

Only 87 here too...no problems whatsoever. I did use 91 for the first tank, but after switching over I saw no difference. 87's the recommended anyways...

cjjtulsa · 01-03-2006, 03:28 PM

Ran 87 in the M50 the whole time I had it with no knock or problems; the Marauder recommends no less than 90, so I just run premium (92-93).

tlwisner · 01-03-2006, 03:34 PM

I run 87 with no problems. Some people who run premium in their C50s have contracted syphilis from doing so. Don't risk it, use 87.

Now that's enough to scare the hell out of ya!!! So if they run premium..they need to where protection and ride side-saddle???

V-Power = VD. Sorry, it's justy a proven medical fact. Penicillin does help - but get your shots before you go blind. Yes, it's the Premium fuel, it has nothing to do with that party last month when you woke up naked behind a dumpster with a Rosie O'Donnel look-a-like.

I added a poll. I forgot to chech the 'allow multiples' box, so just vote the most relevant.

Iceman99 · 01-03-2006, 09:00 PM

I've used both 87 and 92... dont see any difference in performance ...but since its only a 4 gal tank it only cost about .50 cents more to fill with premium so I use the better gas.

traysvega · 01-03-2006, 09:23 PM

When I first got my 1600 marauder,,even 92 or 93 pinged,,after the install of the cobra fi2000 ,,,pinging all gone,,,,but haven't tried the 87 yet.... prob just keep the ol 93 in it,,,After al what an extra 2 bucks per tank...

still beats the heck out of my crew cab dually which averages 10 miles a gallon...

I got this quote off of another forum. Either he is crazy or really knows his stuff...anybody have an opinion on the following?

"I buy 93 octane. If thats whats actually dispensing or not is another story.

You can run with lower octane, but you increase knock count. Once knock count reaches some limit the ECU retards timing. It takes 4 degrees of retard to quench the knock of 1 degree too much timing.

More timing gives more power and mileage. Some of you have posted in the past that you get better mileage from resetting the ECU. This is reseting the timing table back to zero. You should not have to do this if you have enough octane to keep the knock sensor happy.

I'm guessing that you can go farther per dollar on the higher octane because of the increased timing.

It would be very hard to prove this without running several tankfuls of each gas through to get the ecu set to each gas. Resetting the ECU gives the lower quality gas a temporary mileage advantage."

Half a cent? That's a deal!

Sure, the bike will retard timing, IF it senses knock. It probably won't if you follow the recommended grade. If it does knock due to poor quality or extreme conditions, it's a temporary thing. I'm sure the timing is not permanently retarded.

First tank in the S50 was 87 (from the dealer) and the bike was sluggish and had poor throttle response at low speeds. With 89 octane and above it cleared up all those problems and ran much smoother.

**inspiron** · 01-04-2006, 04:04 AM

I've tried all of the fuels available here: 92, 95, 98 and 100 RON. Suzuki recommends 92 RON for my bike, and I didn't notice any improvements by using the more expensive fuels. Since they don't sell 92 in Switzerland (it is available in the EU), I fill the tank with 95 RON ... "regular".

In Europe, the octane is measured using the RON method, whereas the USA uses the (RON+MON)/2 method, which usually gives lower results.

Quote:

There are two types of octane numbers for gasoline, the Motor Octane Number (MON) and the Research Octane Number (RON). The ASTM methods for MON and RON use the same test engine, but operate under different conditions. MON is a measure of performance of the fuel at high speeds or under heavy loads, while RON repersents the performance during low speed conditions. The octane number displayed at the pump is the average of these two values ([R+M]/2).

Doll ?

Here are a couple of articles I found on another forum about octane.

Matt C · 01-08-2006, 02:27 AM

03 Maruader, 03 Blaster ATV, 03 YZ85, and they all perform better with higher octane fuel.

Best way to know for sure is to ride your bike with a tank of each and see for yourself....that's what i did!
