[QUOTE=95331140;2655875]Maybe it could be better for keeping the injectors cleaner for the long-term..[/QUOTE
I don't believe it would make a lot of difference to the injectors. That being said all injectors will eventually need cleaning & new "O" rings fitted, usually after well over 100,000km. I believe a lot will depend on driving style as well - a car that has been babied will carbon up the injectors sooner than an engine that is given a good workout from time to time.
i really dont know y u guys are getting 95 when its like 5c more to get 98 octant fuel. (some how i seem to have always though vpower was 99 octant)
anyway the vpower and ultimate cleans your engine :D isnt that 5c(X 40L :D) well spent.
I totally agreeQuote:

sorry if it's a stupid question.. just a newbie..
I am afraid I can't see the point of running either 95 or 98 on a car designed to run on 91, unless of course you have money to burn which is in fact what you would be doing.
:eek:hmmm.. i'm really torn about what's a better thing to do now :) lolQuote:

Guys, I think were really need to use the KIS method - Keep it simple....I have run a company commodore on 91, and accidently 98 one day, and I couldn't not tell the difference in running/km on the engine...fact is 91 is a better quality than the Yanks get, as there regular fuel starts at 89.....and the fact that 95% of cars all round australia run on 91, with no probs everyday!
When I pick mine car up, she'll be running on normal unleaded, not less there is a proven cost benefit for me to upgrade to 95/98, and to date, there is absoutly no evidents which proves the latter....
Save the extra cents per litre for next fill up! :)
Cheers Steve
I put this in another thread about petrol ages back.
I'm not sure about the other brands, but my old man ran a major project for BP with Ultimate Petrol before it came into circulation in NZ around 2004 and was used to for test results based on fuel production, and was being used for BP HQ in London, and has what used to push for Ultimate 102 in England.
The tests did prove bp ultimate 98 to be considerably better for your car than 91 or 95.
to recap on the other post. they took 3 new cars from a range of dealers, corolla, maxima, ss commodore, base model wrx, 3 series bmw etc. they would fill up each car and label them, car 91, car 95, car 98 to do with octane. they even did some motor bikes as well.
each car had 2 designated drivers a day that would perform a 300km circa loop around a part of the north island in NZ. 2 loops a day.
this was done to each car for around 2 weeks or so.
each car had a gps system hooked up, odometers verified and only ran on a certain type of petrol for the 10000 or so km's
as well as this they went to the car market and found a bunch of used cars and they did some work to the engines to run i think half the cyclinders on 91, and half on 98.
that may not be right as i'm not a mechanic minded person, but they were able to split the same engine into 2 fuel fed compartments.
they measured the carbon build up in all car engines with a barometer before the engines were split up, and had some verified car specialist brought out from UK that was involved in respected car projects, expert in field that can verify findings.
after 2 weeks doing these loops, they checked all the engines. every 91 and 95 car had carbon build up, the 98 cars had very little. the used cars actually dropped carbon build up on the 98 section of the car, and the 91 section had gone up.
remember all these cars ran the same loop together so the weather conditions driving conditions, driver behaviour was all calculated similarly and all new cars, same production lines, even same colours.
after 2 weeks they also took the cars to a race track in the north island called manfield, and did a bunch of professional laps by a local track guru and 0-100 times.
in all cases the 98 cars were faster, some considerably, some by only a slight amount say i dunno, wrx 6.1seconds on 98, 6.2seconds on 91. but, one in particular was a v6 maxima at the time. on 91 gas it say ran 8.7 0-100, on 98 it ran 7.6.
since then i always ran my cars on 98. i even had an old h22a bb4 prelude that had over 220k on the clock, nearly all the vtecs out there in NZ had issues over 180k, i had my car from 120k, always ran ultimate, always ran it hard. the engine was awesome, no issues what so ever.
so i think if you put the cleaner gas in your car one off you probably won't see much difference, probably nothing. but if you run it all the time you will have benefits and for the small price difference, $4 a fill or whatever, your car is getting better treatment.
just got my 2010 vti last week and filled it full last wed to the top. its done 500kms now and still have 4 bars left. running V-power. i think i can manage to get 600kms out of it :D.
U have in excess of 100km left once your low fuel light comes on, & it won't be on with 4 bars left.Quote:

today i ran it down even more later in the day and was scared it was going to run out of fuel, so drove it to about 574km (should still be able to do abou 70km until end of the tank) and ended filling it 44L. so ruffly 7.6L/100km for my first full tank, this was for peak hour and highway driving for 1 week.
