United Plus Petrol In A Skyline

[Jetdat]

my car was tuned with v-racing 100, now i am using united 100 with no problems at all, the knock levels are identical to v-racing if not slightly better.

atleast 20,000 kms on 100 octane (the purple pump) from united on princess hwy near springvale,police rd making just under 300kws tuned on 100octane no probs what so ever....filled up last wenesday at $1.12 a litre

Was there any difference in power between the tunes? Have you filled up with 98 since when 100 wasn't available?

in my opinion....

i have used both united plus and v-power. whether its psychological or actual gains i believe in my opinion the v-power was a much better fuel for my car based on daily driving performance and kilometres per tank.

vehicle: r34 GTT sedan. completely stock no engine mods or exhaust.

fuel period used: 1 month on each.

route taken: same route 7days a week to work and back.

result:

the exact same route was taken each day. i did my best to drive it consistently for the 2 month test period. no flooring or burning people off at the lights mostly freeway driving with the occasional squirt.

the result i got was 455km out of a tank filled consistently each time at 51 litres using united plus fuel.

whereas

the v-power gave me 475km out of a tank filled consistently each time at 51 litres.

Not much difference in terms of km outcome however i did notice when using united plus petrol it did run a little more rough. cold starts were not as smooth as when i ran with v-power. when i did give it a little squirt it wasnt as smooth as v-power. v-power just seemed more suited to my car. the engine seemed more responsive and quieter and not as hesitent. Overall a much better fuel in my opinion.

In conclusion i would have to say, if you can afford to drive a turbo car or any type of sports car, the last thing you should be complaining about is fuel. Dont be a tightass over a couple of dollars because at the end of the day if all fuels were priced the same i gurantee everyone would be using "reputable" brand fuels.

cheers everyone

there was considrable difference between 98 and 100 fuels when i had mine tuned, at racepace, more power thru the whole rev range.

i have used 98 a couple of times when 100 was not available but i stayed away from boost and did not load the engine.

Ive recently been using the united 100 as my car has been tuned for 100. Its great, knock levels are actually better on the same tune. Dont care about ecconomy at all, just knock and power.

I'm now testnig a E85 blend and slowly adding in more timing to the tune..e85 is the shit, havnt done a dyno but knock is staying ok with a few more degreess accross the map everywhere. ethanol is great! just dont spill it on ur paint..

My mates were filling up at United today before our cruise, so I decided to try the 100...Car ran faultlessly all day, low knock levels for some fairly 'spirited' driving

[Jetdat]

went to fill up on 100 today on princes hwy, they were out..

they always seem to be out of 100 octane on princess hwy but i guess taht just means that there stock just rotates and they dont have old fuel

Then higher the octane - the bigger the bang - more heat is produced - more power is generated

[HoWiE_Au]

I suggest you should only use BP ulimate there would be less then a handfull that would reject this claim unless u have had contaminated fuel

[kimbod]

DuFFR32, that is not entirely correct. The higher the octane[ RON] the less chance of knocking and pinging. RON is the fuels ability to resist knocking not volitility . Higher RON lets the ecu feed in more timing for more power until the knock sensor hears the knock or approach and reduces the timing back to safe levels.

[BeEnAr]

he's right, the ethanol in the fuel helps to burn the fuel better in the combustion chamber, more burn = bigger bang = more power = greater fuel consumption

[scarface_au]

well thats just your opinion..

it could not be souly responsible for it, there are other factors that may have obviously contributed. All i am saying is i dont believe its wise to be running this fuel consistently in a NA. Why not just run it on normal unleaded and you will have no drama's

Well it's my opinion too. Most modern cars are quite capable of running ethanol, whereas older cars can be totally stuffed up. I don't know where the cut-off is, it probably varies by model, but I wouldn't even think of putting ethanol in, say, a pre-1990 car. Generally I'd say if your car was built before ethanol became widely used, don't do it.

I would never put ethanol in my car anyway unless it's specifically designed for it, but I'm prejudiced ;-)

I've said it before and I'll say it again in yet another thread about United Fuel.

My GF's Datsun 1200 has run exclusively on Plus ULP (95) octane for at least the last two years. All the fuel system, carburettor etc are fine, and this is in a motor dating from 1973!

I run the Boost 98 in my car when I have to, the only difference is that it seems to use more of it than normal 98 octane.

My old VN wouldn't start properly on United fuel (yes I did test this by running the tank down and filling up from a normal servo and United). I can't explain this phenomena.
