Fuel - Suzuki Across

When I had my CBR250RR, I was warned against using Shell Optimax, so I tend to use BP 95 ron in my bikes

Hey Brad
Which fuel is best, I wouldn't know. As a practise I always use 95 in my bikes. One area that I have found beneficial is a fuel additive that I put in my CBR 1100 every fourth or fifth tank full. My mechanic recommended it and I have not been disappointed with the results. Sadly I can't remember the name of the product, will get back to you with the product name soon.

it should make no difference what fuel you stick in to across above 90-91 ron

the across has no knock sensor and not efi, just CDI, two totally different beasts all together.

run the cheapest 90-91 fuel you can lay your hands on and be done with it.

disassemble the carbs and give them a good clean or throw a cup full of kero in the tank if your feeling lazy and give the carbs a clean, rip the tops off the craps and set the jet one position leaner then stock and get about 5.5 litres of fuel or so to the 100 kays. still over 40Mpg and be done with it.the gsx250f is a heavy bike for a 250 so you wont get much better then that.

 

I've seen a fair bit of discussion on this on other boards (netrider I think) and the consensus there is not to use anything other than 91, for one thing 95/98 makes it hard to start oddly enough.

My experience matches this exactly, I use Vortex 98 in the M3 so I started using it in the Across until I read the other discussion and switched to 91 for a trial. Cold start was much better, I don't really care if I get 40 as opposed to 45 MPG so I'm sticking with 91.

Hi Guys,

Is the BP 95 is still the fuel of choice for the across?

Cheers, Darren

 

personally, as fuel in nsw is crap i run premium 98 in my bikes and LAWNMOWERS. less fuel issues and e10 if left in tank leaves jelly in the carbies.makes sense as alcohol absorbs moisture.recent trip to victoria their 91 had different smell and colour to here.

 

Know what you mean, I normally run the 91 in the 4wd and a 98 once a month. I tried the 95 but found it made no difference to fuel usage.
... And there is no place for e10 ever

 

Great points you make. I've never been a fan of Shell fuels. I always try to use BP or Mobil (now 7/11) in my cars.

One of the biggest things I took out of the articles, was the age of the fuel. So the busier the servo, the fresher the fuel.

"The actual effectiveness of current grade of fuels available can vary depending on how “fresh” they are. Standard unleaded can range from 91-93 octane, 95 premium can vary from 95-96 octane and the 98 premium can vary from 98-100 octane. " (http://roadrider.com.au/gear-reviews/the-fuel-truth)

"Interestingly, though, the fact that bikes run at high RPM and have small cylinders with short flame paths, reduces the octane requirement. This said, BP’s Dale Brown-Kenyon supplied information showing that premium unleaded fuels have a lower corresponding air/fuel ratio. This means you can put more fuel in for the same engine capacity, giving a cooler running engine and producing more power.!" (http://roadrider.com.au/gear-reviews/the-fuel-truth)

So guess I'll be staying on the BP 95 and gauge the km's for the next two tanks and then try a 98 and go from there.

Cheers.

 

why lawnmowers...easy e10 stuffs the carby with jelly due to periods of long lack of use. e10 absorbs water and on mowers use of premium reduces time of dropping carby bowl and cleaning bowl and jets.experience.

 

forgot to ad that e10 rots the inside of rubber fuel lines and corrodes aluminium.if used needs nitrile fuel lines.

 

Cheers for the feedback... Will post an update in a few weeks.

 

And GreyImport, obviously Corona or Tooheys new! lol

 

Corona FTW !!!

 

The averages between mobil 95 and BP 95 are pretty close. A few kms in it. BP average was 188kms to the tank, Mobil 95, 184 kms to the tank. I ran one tank on BP 98, 191 kms to the tank.

Will be on the 95, but much of a muchness to the brand!
