98 in fxr?

**TraD_MaN** · 25th January 2006, 14:05

anyone run there fxr on 98? will it be ok to run it on that? just been told that its wayy better to run bikes on that....

also does AV gas do much in the fxr?

thanks!

oh and also that lil black cap near the motor is that where you poor the oil in?

my oil guage just reads under half so is that to low to go ridding on?

your 150 might run better on 91 actually. 95/98 might be too clean and could burn too hot. AvGas won't do jack for your bike. Nor most bikes. The only machines that benefit are engines that have had a good amount of work done, and need higher rated fuel to get the best out of it. In regular engines, doesn't make much diff at all.

Stick to the cheap stuff, should be the best for ya

High octane is less flammable and therefore needs higher compression to make full and efficient use of it.
Low octane is more flammable and ignites easier.
More octane in a low compression engine will produce less power and run dirtier than a lower octane fuel as the spark will struggle to ignite the mixture.
91 octane is fine in most bikes especially FXR's etc. Run 95 in sportsbikes and don't bother running or paying the difference for 98 its not worth it.
Don't give in to the BP bullshit hype about 98 being cleaner and more powerful, your just adding to their already bloated wallets.
95 is good enough for most, unless its turboed and running 13:1+ comp.

I find my fxr runs better on lower octane fuels (91), especially when its colder. Was running her on 96 for a while and she was taking a long time to warm up ( a bit like my gf). On 91 she runs alot smoother.

Yes the little black cap on the right side of the engine is where the oil goes.

Your bike will run on that much oil but you should think about topping up or better still, doing a change

oh sweet thanks,

ive got 95 in it now and it seems to go ok, but i dunno if its just me but it sounds more "grunty" with 95 other than 91...

how do u do an oil change?

How to do an oil change

1. Undo the black cap

2. Place a container to catch the oil under the engine

3. Undo the sump bung. This is under the engine at the lowest point. Big nut. You cant miss it. Mine was as tight as a virgin so you might struggle with it for a while. I found it made it easier if I removed the bottom fairing around the engine (screws off easily). It makes it easier to get at the nut.

4. Let the oil run out. Make sure you lift the bike up so that it is standing up straight. (this gets all the old oil out)

5. Screw the bung back in

6. Fill her up with new oil. She takes 1litre but just check the little indicator window when you've put it in

7. srew the black cap back on

I think I ended up puting about 1.2l in mine to get the right level (manual says 1l)

P.s. make sure you've got the bike standing up straight and not sitting on the side stand when you check the oil level

oh cool thanks for that phoenixgtr, ill get to it in the weekend

Unless 98's called for ya don't need it. Apparently WRX's need it, are prone to blowing/seizing the rear cylinder otherwise, on 95 etc, 'cause they get too hot and by the time the water gets back there to cool it it's well too hot from the other 3 cylinders, and it dies an early death. I think some Euro beasts call for it too, just do what the petrol flap says.

Runs on 91 petrol.

The oil window markings read: High, low, and oh dear. If you're below the halfway mark, you're below low.
My last oil change needed nearly 1.3l of oil. Drain oil then pour in 1l. Run engine for 30 seconds and have a cuppa. Now proceed to slowly pour in more oil till you've nearly hit the high mark.

Change your oil filter at the same time. Its on the same side as the black oil filler cap but towards the front and is hidden behind that engine casing with three screws. Don't forget to catch any oil the leaks out as you remove the casing.

An ice cream container is suitable to catch all of the oil if you don't have a fancy one.

I've found using one of those solid yellow plastic petrol container funnel the ideal oil filler tube.

Cars and modern bikes computers can allow for different fuels and adjust the timing to stop detonation. My Gixxer's manual states the petrol grades required, which is 91+ using NZ's method of grading petrol. Americans grade it slightly different and list it as 87+.
Avgas will be pointless in your FXR.

Ideally the manual will give two oil capacities, one with a filter change (more), one without (less). Filters are cheap, do one at the same time (it's dead easy).

I'm not disputing what you've said here as I do not claim to be an expert in fuel qualities etc, but we (our company) uses shell cards, hence we know the guys at the local Shell servo very well. One of their guys showed me a Shell release that claimed that BP 98 was worth it, even said Shell were trying to develop their own version. They rated BP's 98 above their own 95. Obviously this is not intended for general release.

Oooops!

The manual says 1litre without an oil filter change or 1.1litre with
