Premium Unleaded

I tried it in a 1FZ-FE 80 Series and whilst I didn't record any figures I didn't get a noticeable improvement in economy. Still about the same kms as I usually get!

Cheers
Scoey!

Heard on radio last night RACV/NRMA complaining about the latest servo scam, is saying they are out of Unleaded to force people to buy PULP!

Didnt think there would be much differecne in profit for them

the responsiveness of cars to PULP changes from vehicle to vehicle. At an extra 5 cents a litre filling the tank with 60 ltr's of PULP will only cost $3 more so why not try two or three tank fulls and carefully monitor the milage.

I have often used PULP in my little car engine and found it helped the economy. Not sure whose economy though. I thought I was getting further per tank but can get good distances with either now as I try a little harder.

Interesting to see the type of road makes quite a difference - more corners and hills mean higher consumption. With flatter roads and longer distances between stops and therefore exelleration points it's easier to get out over 1000 per 60 litre tank - which ever fuel is used. It depends a bit on my feeling at the time as to which I fill up with.

I've got an old VL Commodore and the PULP certainly makes a difference to its get up and go as well as the distance it travels on a tank. After a few tanks of normal ULP it starts to idle rough and be a little unco-operative of a morning.
That's the signal for a tank of PULP and it settles down again after that. So for me in that Commodore it does make a difference. Oh, I either use the BP up the road or the Shell a little farther away.

Had to laugh listening to the radio this morning.
The NRMA/RACQ/RACV/RACSA and all the other variants have a burr up their collective arses at the moment.
They've just realised the only capital city in Australia that hasn't had a petrol price hike this week is Perth!! And guess what else they realised?
It's the only state without a long weekend this weekend. Guess what they also just realised?
That the oil companies are probably trying to cash in on the extra travel of a long weekend!! Makes you glad to be a member!!

I have given up trying - too many variables - eg airconditioning, exact same roads, load in vehicle etc etc
I use 95 in Jack and 98 in Kluger - They have both shown that as their preference for performance

Depends on the car and it the computer... Works on Prados.
Standard unleaded 91 octane - fuel economy around 15l per 100km...
Premium unleaded 98 octane - fuel economy around 13.5l per 100km...
As usual more economy on freeway vs city driving.

On prados computer takes up to 3000km to fully adjust, so you need to use the same fuel for 2-3 fuel tanks before you notice any difference.

There have been several miricales lately. Drove past a servo last night ULP 147.5 c/l, Diesel 139.5 c/l.

From my experience around town driving makes no difference but last year on our outback jaunt I used premium and got much better economy. I had to check the numbers 3 times and I'm still not convinced that we managed to get the indicated economy. We're off again soon for a couple of weeks and I'm trying premium again to see if I can duplicate the results. Until then I don't think a one-off result meets your criteria of "good quantuty of data".

I'll let you all in on a little tip, Shell's new Unleaded is around 95-96 octane, pretty close to premium unleaded. If you can buy it for the same price as normal unleaded, 91 octane, then do it.! It's the closest thing you'll get to premium without having to pay for it.

Tried BP Ultimate for a while. (about 3 months)
There was a noticeable difference in power.
Could cruise up a hill in O/D that would normally force the autoshift to drop down.
The Hill I travel on a daily basis.

Couldn't get a conclusive result of any improvement in economy however and at 8 c/l more than standard ULP, I ceased using it.

I cant believe that fuel companies seriously expect us to believe that there is no such thing as price fixing going on. The industry needs to be re=-regulated as it was twenty odd years ago and have them present a case each time they seek a rise. Lets see Mr Howard says deregulation equals lower prices through more competition well so far I haven't seen one industry that has been de-regulated that hasn't resulted in skyrocketing prices due to company greed and higher profits. prime example is banks multi billion dollar six monthly profits where our top companies like BHP make 400 million a year. Yep de-regulation, cheaper fuel prices for the motorist. Politicians should be doused in it.

I had a 95 v8 DISCO a few years back that when using bp Ultimate i would get an extra 100km's out of 100 litres.. From memory it worked out about the same cost per km and I had a better range from one tank of fuel and seemed to have slightly more power.

Though my current 3 litre v6 Triton doesn't seem to make much difference. Maybe the lower technologically advanced engine benefits more from it???
