BP Fuel

Hi guys,

Just came from the Fuel servo, BP, and they had 3 different types of unleaded
:confused:

Anyway, I know the "ultimate" is the new fuel at 98 Octane, and the old Premium is at 95. The price difference is 6cents!!! Now in melb, Ultimate goes from about 105 - 115.. which is a lot!

Anyway, is there much diff between 95 and 98? Don't want to sound cheap, but I can travel >1000kms in a week, so this will make a huge diff in cost.

I'm not comparing shell vs mobile vs bp. Just want to know what you guys think of the octane ratings.

Thanks.

Our cars are detuned anyway, it requires 95 octane only, so don't worry about it

yah 95 shld be fine.. but i've heard givin your car 98 octane gives it more mileage. someone plz confirm it.

So its not worth paying th eextra 6cents for the 98octane?

More octane and more oxygen in 98 RON Ultimate
Whch means more horsepower
Which means do don't have to use as much throttle when driving. Doesn;t help if you just floor it all the time like me...
Personally, in Sydney, the 98ron fuels are cleaner, and are used at as high a frequency as regular unleaded. MOST service stations in Sydney that are shell or BP actually have the 98RON fuel in there,they just haven't changed the labelling on the servo...

Anyhoo, Ulimate is the same as Optimax - both are made in the same refinery, no matter where in Australia you live - only difference is who makes it on either end of the country

Also - it is important to only use BIG servos as they turn over more fuel, therefore they need to get more fuel in - for quality, you want the freshest fuel you can get. Small servos turn over less of the High Performance fuel, and therefore, it gets old and crusty - bad news sometimes.

In all honesty, my car runs better on the 98ron than it does on the 95 - no miss at all on the engine. However, on newer low perofmance engines, 98 ron is not really worth it - it is debatable though.

IMO - only use 98ron. Why?? Better fuel and th more people sue it, the lower the price gets

the only time i ever used regular unleaded was on my first car which was a '90 mitsubishi magna.
but when the hondas started coming, nothing but Premium Unleaded for my car.

I just paid 118cents for a litre petrol for BP ultimate last week... grrrrrr.. I hate filling up at the city

Chook you bring up an interesting point. I too am very picky with going to servos who are constantly busy to get the "freshest" fuel.

However in saying this...... if we look at the control fuel for the V8 Supercars, "Optimax", since it is a control fuel a batch is taken at the start of the season and stored to last throughout the entire season, so there is no variation/advantage........ everyone uses the same fuel with possibly the same level of denaturing as the season progresses.

On the optimax FAQ's optimax is rated at 98.4 RON, and is supposed to quite stable to the point that it will maintain a min of 98 RON for a year providing that it is stored accordingly.

BP Ultimate is always the cheapest when I compare it with Optimax and Synergy 8000 (all those servos are around my area), BP wins hands down in that case.

I thought it would get more potent the longer it sits around.... like alcohol:)

not really..
i reckon optimax is cheaper...
you drive into Shell down at cabra...
optimax averages around $1.07c per litre depending on the day.
drive into BP in cabra, ultimate averages around $1.20c....
now thats a whopping 13c difference.

your topping your tank till about 43-45litres.... 45 x 13c
thats about 6 bucks your saving per tank!. this is in a 4cyl car as well

My Pref is BP - Mobil - Optimax.

Optimax feels sluggish (for me anyway).

LOL. Considering BP and Shell are the same, and Mobil Synergy 8000 is only 97RON and low oxygen....

I hate optimax. Ultimate owns it all over the shop. Somehow the statement that they are the same seems like bullshit to me.

i see no diff in both ultimate and optimax.
except in price =P
my car still goes good...
i havent tried synergy though...

http://forums.skylinesdownunder.co.n...5&pagenumber=4

Read ghostriders comments, he did tests on the fuels...

Eh? Synergy is only 87RON? typo?

Someone explain this.

BP ultimate + All changes under 4K NO VTEC, tried to get max mileage, and i get 450km.

Normal Crap Unleaded + Mass VTEC and Racing Around, and i got 480kms

PLEASE EXPLAIN!

i agree with MCchook...they r both the same...i bet its all psychological...if one were to swap the brands around but use same fuels, i think it would be interesting :o

Shell Optimax + Coles Express Dockets :D

I've heard that Optimax and Ultimate are the same a few times now, but they honestly feel different, Unless its got more to do with the locations at which I buy them, ultimate having been used by BP for a shorter time, therefor cleaner tanks maybe?

I've always been a user of BP Ultimate, but a week ago, I was dangerously low on fuel so I had to pull into the nearest petrol station and it happened to be Shell.

Anyway, I topped up the car with Optimax and I've got more km's from this tank of fuel than using Ultimate.

What surprised me the most is that during the past week, I've been gunning the car more than usual yet still used less petrol!

To rule out this being a freak result, I've topped up again with Optimax this week and will be driving normally to compare the results once again.

i was in the exact situation this week , ( BP user going to optimax as last resource ) and its hard to beleive that there is no difference between the two.
I agree that optimax is more fuel efficient ..doin my usual routine, it has lasted me signifcantly longer than the use of ultimate.
However, optimax does feel a lot more sluggish than ultimate as Ronin said before.
could be a matter of the type of car u have and how well it responds to different fuels.

Suga....
its all in your head...
inside your thinking.... bp is great, shell is shit, bp is great, shell is shit..
and while your driving... you'll always have that thought in your head... =P
its only sluggish when you fill in regular unleaded! =P

Optimax gets more mileage than Ultimate, at least 50km on a full tank
adds up in a year!

Excuse me! I always thought Shell was the best! been using it for years until i tried BP cause of this forum, and others.

Anyway, maybe Shell puts in more stabilizers.. like the fuel is supposed to be denser.

But last few comments are right. Shell = 50ks more, but slower off the mark.

I have noticed recently that optimax pings more than mobil, mobil has better cleaner response up high in the rev range, but I get better mileage out of BP.

i think your assuming too much
i've never been biased against any premium unleaded fuels

i've tried them all just to see the difference between them .. used to use optimax all the time .. and through my experience i have found that bp gives me the best performance
so hence, its not all in my head

You can't base your mileage on a tank of fuel. Each petrol station use different pumps or nozzles, so they cut off at different levels.

What you have to do is use 2 tanks of fuel to find out the mileage:
You use a brand, fill it until it cuts off, drive around and note the mileage. Go back to that same station, use the same pump and fill up till it cuts off, note the amount of petrol filled and then do the calculations.

Repeat for another brand of fuel. Always use the same pump and fill it the same part of the day (mornings are colder, so you get more fuel in because it is more dense).

when i change fuels I use the same fuel for no less than 1 week so I know the tank has used up all the excess older fuel.

For my ED carby motor, BP definitly gets more mileage than other premium fuels.

Always used optimax, until my car started getting massive lags of acceleration... thought it was an engine problem until.. Hanny told me to use BP instead. Problem solved.. too much addictive in optimax = bad for engine in the long run..
Never use optimax unless i have to now :)
the price are just about the same on Cumberland Hwy at cabra west
