SHELL optimax VS BP ultimate FUEL ! For DOHC VTEC

out of the two...

BP Ultimate... better..

but Mobil 8000 is very good aswell... i used to only use that...

now im on V-Power coz ive got so many vouchers... and its on the highway on the way home from work...

except for mileage...

i have amate who works at a petrol refinery and the best fuel on the market is the bp then the mobile, actually they are both exactly the samed fule and are the best fuels to use...( bp ultimate and mobile synergy 8000)
he told me that the bp truck turns up they fill it with ultimate and then the mobile truck rocks up and they use the saqme pump to fill it, so its actually the best and same fuel on the market......i find that my type r runs best on bp ulitmate so i never change......
better fuel ecconomy as well......

I to have the same opinion on BP ultimate. I get abt 50 km from Bp ultimate than V power. My next door neighbour has same view.

I'm not a petrol expert but I do know my car. The difference in the two you can tell. (Well i can neways).

Most of my friends said BP Ultimate has better power and even run the engine safter as it does not explode better than optimax.

A friend of mine told me that a honda dealer recommanded BP either.

Some said optimax is the best fuel in Australia.. and some said it is only good for turbo..

my gf's driving instructor said he used to read something was talking about shell and BP fuel. He said BP is always better, as it explode much better than shell.. :confused:

Now i found everyone has different story :D

for me I could feel that shell optimax has better power, but i am not sure.. they both has 98 octane. Or maybe Shell has a cleaner petrol station, coles express discount that makes me feel better.

Any idea ???? just tell me how you feel or did anyone even put it on a dyno to test? but it must be done straight away.. like run with bp, clear the fuel tank put optimax .. :D

A mate of mine had fuel tested with his families formular holden race car and found that BP ultimate gave the best results closely followed by mobil 8000.
the results he got also stated that shell fuel was the dirtiest.

This was done a little over a year ago so the fuel mixture of shell may have changed since then. but i still go by it and only get mobil or bp.

Fuel efficiency is again similar when comparing 98's but with the V-Power Racing if im driving conservitivly i can get around 520kms out of a tank. (Stock VTi-R) With occaisonal trips into the VTEC Range.

you shouldnt be using any ethanol mixed fuel in your mid-90s honda...thats just silly

Why?! An Automotive Engineer (mate) said it will be fine expessially if its only 5%, they say all the "check with your manufacturer" just to be on the safe side.

Is their any particular reason behind your opinion? or facts?

Late Addition: I just went back to BP Ultimate (98RON) Today and the fuel efficiency after clocking it was awful. My driving habits didn't change nor did the driving conditions. For eg. Half a tank of BP Ultimate will take me 230km's, where as half a tank of V-Power Racing will take me almost 275kms. I have to say though the power is similar, however I think I get a greater low end throttle response and torque from V-Power Racing.

ATTENTION:
A Comparasion on the TV Show 5th Gear showed V-Power(98RON) to give greater power and torque over BP Ultimate in both High Compression N/A and Turbo's (Examples used were a honda i think and a Subaru WRX) Not to mention better fuel economy. So after sticking to shell's fuels for a few weeks that just closed the deal for me. Expessially with my latest two BP Ultimate experiences, Although as stated above the power is very similar, the fuel efficiency is difficult to ignore.

Cheers

I am sorry but it sounds a bit far-fetched that there would bhe such a difference in efficiency:/ How can you be sure that it was exactly 50% of the tank with both fuels? I get around 550 - 600 k's a tank for my dc5r and that is with BP ultimate or Mobile 8000. I can get the same with vpower as well though. As for which is better i dont have the definitive answer but i still believe what my mate told me as he is in a more credible position than me. I filled with vpower racing (100) once to test it out. Only got 400 k's which i suppose is not too bad considering i was fanging around quite a bit.

Also which ep of 5th gear? i would love to see it :)

It was on foxtel a week ago (i think its Adventure 1) should be replayed soon. When i say half a tank i put 25 litres in and fill up at as close as i can get to the same time (the instant the fuel light stays on when the car is on a flat surface). Although when i drove to work this morning i managed to pull another 20 or so km's out of the tank of BP, i can only manage to get in the mid 500's per tank with shell's v-power line.

Unless i should run a bit of BP to "run it though" but i dont see it making that much differance.

I would rather use BP fuel trust me, its about 5 houses down the road, but it doesnt work well for me. So i travel to doncaster east to get V-Power/Racing.

if you use a different fuel in the exact next tank your ECU might not trim optimum...give it 2 or 3 "tanks" or amounts for your engine to maximize the fuel its using.

I think i'll stick it out with BP Ultimate for a while, and put some faith in the above posts. I'll update everyone in a week or two of my findings.

Thanks.

To anyone reading this thread looking for information, just remember that almost all of what is being posted is opinions only.
A car is not a calibrated device for measuring fuel consumption and there are many other variables in these 'tests' that can and will affect the outcome. All in all what you are buying when you fill up with petrol is a mass produced product that must fall within quality control parameters, i.e. not every batch is the same but it it is within spec.

Even just in the transport and storage process more variables are added- how old is the fuel? what temperature? (when it comes from the terminal it is 'hot' and cools and therefore shrinks when it sits in the ground).

Pumps at the servo are not totally accurate, it is very rare that you will be overcharged due to the nature of the calibration equipment used but I have seen many a pump giving away up to 200ml for every 10L sold, that would affect these 'tests'.
All in all you can find just as much variation between different servos dispensing the same company's fuel, as the different companies themselves.

Having said all that I do agree that Vortex98 and Ultimate are the best fuels for my car, but this is based on the manufacturing process used.
