My MPG went up

[kbwitt]

I read somewhere that the regular gas might be a lot fresher and give better mpg.
I use Cheron the station closest to my house is always busy they sell a lot of gas but maybe just not high test. I have tried the lowest price at otherCheverons same results better MPG.
I am not educated on gas qualities but maybe someone will chime in if there is a
difference on fresh and old fuel. Kenn

old vs. fresh

Octane will diminish over time.......but it takes about 30 days or more.....and the drop isn't dramatic........I find it hard to believe the gas at a Gas Station could be even close to that old.................I think if they sold that little gas they would go out of business.....JMHO....Mike :bbq:

Fuel over 90 days old will lose a little Octane, but the real culprit is eventual evaporation and varnishing begins to take place. After 6-9 months is where the real damage occurs and clogs Fuel injectors and muck's up Carburetors with varnish. For those of you who store over the winter I would recommend draining the fuel and when refilling use a good brand of Fuel Injector/Carburetor cleaner for the first tank or so. Follow the directions!

High octane prevents pre ignition in high reving engines, low grades of fuel while not good for certain engines has more BTU and will always give better fuel economy and power in the appropriate engine.

Anyone else runing 87 occtane?

 

[CanAmChris]

93 from Sunoco in the bikes. (unless it is a road trip emergency.)

 

[Deecheff]

I have always put 93 octain in my bike. BRP recomends running 93.

87 Octane

Anyone else runing 87 occtane?

I have for 18,000 miles and my 1330 loves it.......I do add a tiny amount of Startron to every fill-up, to cancel the Ethyl.................Mike :bbq:

 

[BLUEKNIGHT911]

REALLY - 93

I have always put 93 octain in my bike. BRP recomends running 93.

Interesting ....in my Owners Manual it says 91 Octane ( for 2014 RT ).........Mike :bbq:

 

[robtdonna]

:agree:

Propane

New,fresh gasoline has propain gas in it. It's not added but it evaporats first. It is highly useful in starting any ICE motor. Ever open a sealed, well closed gas can??? Hear that rush of pressure as you open it. Propane.

Fresh gas has it, stale, old gas does not. Good idea to buy fuel from a high volume station.

Stale fuel causes:::

Run it all the time with no problem. Talked with the lead mechanic at the dealership and he said us 87 and that anything else was just a waste. Ran some 91 fo a while to see if it helped the gas mileage but it didn't

 

[Rohaianan]

To be clear on 87 octane

So the manual indicates to use 91 octane and many of you are using 87 octane? Are those who are using the lower octane sense any hesitation, pinging, or any other negative indications? 18k using 87 octane gas is alot of miles. i have observed that if a vehicle call for 91octane and use lower octane; i get worse gas mileage.

87 OCTANE

:agree:.....and as I said in my post # 8, I have 18,000 + miles. Lots of people here have lots of anecdotal theories and of course some go by the BRP Kool-Aid thing............I may be the only one who has actually done some real world testing on whether you need 91 octane or not.......It came out .....NOT.....PS , I average 39 MPG on 87 ...I apologize to everyone I have now offended ..........................Mike :bbq:...................PPS, If you are Drag Racing run 91 Ethyl-free and at least 5 tanks prior so the system can adjust ......JMHO

The 1330s will actually run on almost anything that they can get to burn... The computers will do what is necessary to prevent the lousier fuels from hurting the engine. They'll retard the timing, and probably diddle around with the injectors as well. nojoke
But ANY 12:1 compression engine will run better, and more efficiently on the fuel type that it was designed to use.
I use 93 octane as well; there's nobody around me that sells 91...

That being the case:

 

[Jheck]

I run 93 octane in my :spyder2:, just because it does't have ethanol in it. And it never hurts to go by the manufacturers recommend info. On octane. The no ethanol is just my preferance.

What a dyno says about fuels

I have paid for countless dyno runs in setting up street and racing cycles.
On a motor putting out about 100 hp, FRESH 87 octane gas from a busy gas station ALWAYS nets 5hp more than 93 Octane pure FRESH gas.
The reason to go with pure gas at 93 octane is combustion temperatures drop about 15 degrees over 87 cotane.
Cooler temperatures equal longer engine life which is why Can-am wants higher octane. But in a water cooled engine with the latest high volume upper cylinder oil cooling, there is no wrong choice.
Always good to have an octane thread to give us something to take our minds off winter.

I'm stuck running 91 with 10% ethynal

Anyone else runing 87 occtane?

When I am on the road in rural Iowa, Kansas, Missouri and Nebraska, I fill up with whatever is available because walking along the side of the highway sucks. I stopped thinking about gas mileage when I got rid of my Harley. I now just look at the gas gauge and stop when I need gas.

 

[jerpinoy]

I don't mess ,BRP recommend 93.
