Shell V-Power vs BP 98 oct

[canman]

I might get chance to do some comparisons on the dyno soon with the Civic as I'm going to get it back on there to tune out some low end (below 2000rpm) drivability stuff so I'll run it on 95 for the first runs, then tune it up for Mobil Ethanol blend.

Had a chat with people today about the Gull 10% ethanol mix and they've got some proven results with that on the dyno. Basically it seems with Ethanol it's more resistant to detonation so you can get more power from running more timing without hassles......

I'll let you know if I get anything concrete, but the seat of the pants 'ometer in my GTR says the Mobil blend is smoother than the Ultimate fuel and much better than the Shell V-Power....

Like somone else said, if you're not running ITR, STI, EVO etc 98 is a waste of money. You're better off getting 95 and use octane booster/injector cleaner every now and then.

All of the 95 sold in Auckland comes down a pipeline from the refinery at Marsden Point. Apart from additives such as Caltex Techron, there is NO other difference between the brands.

But the petrol won't always be exactly the same - it may have the same RON rating, but the composition will vary. So you could fill up at Shell one week and Caltex the next, but any difference will be due to variations in refining the petrol, not the brand.

Until Shell brings out their 100 octane V-power here, think I'm gona stick with BP 98. May be pricey but guess if you wana drive a performance car you gotta pay the price that comes with it.

Semi related question. I was talking to a guy at Mobil in Paremata today who said that apparently mobil are shifting their Ethanol Blend to a BioEthanol blend, and are as such, removing all of their Eth Blend (97.5 Oct. Min.) until they get this new bio in, but I dont know annything about it, does anyone else?

I personally like the Ethanol Blend as the better high octane fuel - that is over V-Power and Ultimate.

Switched over for a "test" must say its pretty good on economy, pulled mad vtaks as well so must be a 1-up. 98 here is crap it doesnt turn over quite fast so you get the "stale, old stuff"

I used a bit more than half tank and refill it today. 290km and 23 litres. 7.9L/100km with the V-power is not bad for the B18C. It seems to have more pick up after refilling as well.

I can't tell the difference performance wise between the Shell or Mobil and haven't run the car long enough to get a good feel for efficiency. I stick with the mobil 98 cause it's avail at my local.

Is that much 100km driving? Seems v good efficiency. I do most of my driving in 50kms areas and I'm getting roughly 10.0L/100km out of my CTR. (Not sure if that's good or bad).

V Power petrol contains Shell’s advanced
additive technology, which is designed to protect the engine from the build up of
harmful deposits. This improves performance by keeping clean fuel injectors,
carburettors and inlet valves and leads to consistently good gasoline/air mixture
preparation, better combustion and better driveability.

V Power
Colour - Visual Yellow
Octane Number - ASTM D2699 95.2

those saying its not worth BP98 in a stock car havent done any real tests IMHO

those that know me know that I do a fuckload of KMs, and I get $50 a week free from work, but its on a caltex card, so its Techron 95 usually....

it goes down pretty quick when doing heavy driving, and is average at best when taking it easy..

if I put in BP98, it last faaarken ages compared, personally with the price going up soo much lately, you dont notice any price diff with 98 anyways.....so personally I prefer 98 Ultimate.

I did put in $30 of V power in on friday, and it hasnt gone down as fast as I thought it would...will have to try a tank at some stage, see what I get

just a side note, what is teh Brand of Mobil high octane?? is it synergy 5000??

got told by the dude at Mobil that "Synergy 5000 is the same as 98"

I think he was being a BS artist, but not sure

Synergy 8000

Synergy 5000 is 95.

Synergy - Mobil Fuel System - Product Selection

sucks for me.. i need to run 98.. car tuned on it.. and its high compression + boost.. so need as little chance of detonation as possible..

what i dont get is why bp 98 is 2.269 and 96/5 is 2.17... surely cant cost THAT much difference to make it..

Sweet, thought so...

My calling him a cocksucking fuckwit behind his back was warranted, lol

[sk-itr]

I didnt think that V power Shell petrol was that good in my ITR. Hate those BP bumps when used to fill 98 Ultimate from BP now I changed to Shell V power and really like it.

[SLOTEG]

i have a full tank of gull biofuel onboard at the moment, so far its around 380km from 40L and i still have a quarter tank left, gonna see if it compares with my normal 95 tankload.
my last full tank was pak'n'save 95, as the 10c off a litre helps me out a fair bit (1500km a week) with the cost and i did 542km/40L full to empty
dont really notice if there is more power or not on each blend, as im doin 100km for 75% of my daily drive and only drop a gear/wot to pass and climb the hills and do the twisty bits
also, the biofuel smells a little funny

[dazznz]

I can't believe that you guys can tell a difference between power and performance on any of these fuels. If you look at people that run race fuel, most of them are not doing it for power or anything, they do it because it does not burn as hot as normal gas. The way i understand it is the higher the octane rating the lower ther burn temp.

Untill i put the new highly stung motor in my teg, i always used to run it on Shell 95. Never had any issues doing this, and that was always when i was racing, so i don't really see the need for road cars to being running on 98......

[SK1TZ- EF]

I dont notice a huge power increase with teh 98, but as I said, it seems to get me better KMs from a tank

Hmm, I have a year's worth of mileage for filling my civic on 98, I wonder if I should chuck 91 or 95 in for a month and see if there is any difference.

Yeh do it, see how it goes.

[SK1TZ- EF]

I wouldnt put 91 in anything....not even a lawnmower, its that shitty a fuel, only good for firebombs....they must sell a fair bit of 91 in Invercargill, lol

Nothing wrong with the stuff if youve got a stock lowish compression engine.! You will gain no more power, by just changing petrol if your engine isnt tuned for it!

[lincooln]

i dont know aye. I had it in my standard suzuki vitara and it started causing knocking, smoke, lack of power etc. put 95 in it and its all gone away. tried 98 just to see what happens and well it did shit all. to be honest

U mighta noticed a difference if you reset the ECU via the Battery terminal for a couple min's i did it once i got hm after filling up the next day i drove it hard for a bit then parked it up at work till lunchtime. It seemed like my car had more life in her when i went out for lunch that day.

I managed to get 8.1/100km round town pretty close to someone else's economy further up the pg 7.9L/100km but then its 2.2 over 1.8 mayeb thats why, & i didnt drive like a nana all the time either.

So after using V-power for about a month now i'd give it the thumb's up bein that its fairly economical and not much lesser performance than 98 i dont think ill go back to 98 to tell the truth it's to expensive and all you rich bastard's with deep wallet's that wanna cry no 98 is the shit only get that, have you even try'd v-power you maybe plesently surprised, cus I find the problem with 98 your always tempted to put your foot down more just to feel that extra couple of horse power you may gain, V-power is defintly the best right now over mobil's 95, gull or gas as there know'n down here and catex's techron too, dunno about challenge i never go there.

I think Ferrari did well and from reading there little pamflet in there stations you can grab, I think they got it spot on with the additive's they put in it.

[SK1TZ- EF]

yea, well I have been putting in V power when I have had to use my own gas, and its better than caltex, which I think is shitty as hell,(but works got a starcard) and a good, cheaper replacement for my oh so loved 98.

my 2c, again

[Dionysus]

Ok, from next week I will try V power after two years of 98, for two months.

Note, I drive virtually identically each week, same amount of k's, same kind of driving, with the exception of two attempted economy tanks, which improved my efficiency my 200mls!

This won't be a power test (as mentioned by Dazz) the effect is imagined, but purely economy.

Ah crap, anyone know how I can put excel data up so it's all lined up properly?
