Outer Limits 4x4 Board

Searching other sites it seems certain vehicle makes respond better to a single brand of fuel ie late model fords seem to like BP ultimate as a general rule and Minis prefer Shell V Power.

Anyone else recon the extra dollars at the bowser is justified by the return.

PULP is only good for high compresson cars and bikes maybe 4x4 motors as well seeing as they go for slightly larger pistons etc for more torque.

CBR600RR here,
on the bike I would only use optimax or v-power 1st then vortex after that I'd try to never use BP fuel as the bike chews up their fuel.

With Optimax I would get a 4-5 days of easy going riding, on BP easy going would only last 2-3 days plus run like crap after 2-3 tanks.

Vortex was good in the middle type fuel might get 3-4 days but the engine would be good all the time.

Compresson on the bike is 12:1

I could see the differance myself.

Shell say don't use their PULP on un-tuned carby (motor bikes mainly) because it's denser and can clog up the carby you need the carby to be tuned for their fuel.

With the BP and Vortex I found they are mixes as in they take stock ULP fuel and add octane booster doing this doesn't effect carbys.

The Shell PULP isn't a mix.

But now that I've gotten a Diesel I'm really prefering the Diesel to petrol in a major way, if your wanting to travel far get a Diesel.

Not true. Fuels such as Vortex are formulated to clean the fuel system, which in turn can restore power and economy.

Denser?
Taken from Shell and Caltex sites:

Desnisty at 15 degrees C -
Vortex 98 - 740-785 kg/m^3
Shell V-Power - 720-775kg/m^3 also same for V-Power Racing fuel.
Shell PULP - 720-775kg/m^3

So obviously, they spun you BS here to cover there quality control issues.

Are you referring to the new V-Power, or the shell 95?
The V-Power is definately a mix because I don't recall 'Friction Modifying Technology' coming from a barrell or crude oil. The V-Power racing is also a mix, due to its ethanol content.

Taken from Shell Australia website:
"Shell Premium Unleaded also contains additives designed to clean deposits within the engine."
If this isn't a 'mix', I'm not here.

If you have used it, you will know it works.

I have used it.
No difference in power or economy so I went back to 91.

Talk about premium fuel... Dads new car (Pajero Exceed 2007 model) brand new ONLY runs of premium manual says only to use unleaded peterol in exstreme emergencies....

When the V8 got tuned, I could have set it up for PULP and gained power (according to the guy who tuned it) however I chose to set it up for regular ULP cos if I find myself in the middle of nowhere and have to run a tank of shit fuel, I figure it should be OK. If I'm tuned for every last kW out of 98 Octane, I'm guessing I'll be pinging constantly on a low quality fuel.

Don't know if it was right thing to do... just my 2c worth

Not according to mitsubishi.
Their NZ website calls for regular unleaded.
