It used to be they all came through marsden point and except for a few possibly useless additives were exactly same. I recall someone testing them and found no difference. Challange imported own at one stage and was tested as having higher real world octane but then they stopped getting their own. Has this changed? I hear gull does own but as you say we don't get this down south. Isn't all the 95 the same stuff?

I used to work for an oil company and in those days all petrol was the same when it arrived on the ship,each company took their quota. The only difference was the percentage dilution /or if they blended "slops"(got rid of-pipeline flushings-things from diesel, propylene glycol,M.E.K.,alcohols to Vinyl .Acetate.Monomer) into the bulk car fuel storage tanks.Smaller outfits that did not bring in solvents therefore had the purest fuels.

If you are tuning to a point where there is a difference between the brands, then you are probably getting a bit close to the edge.
Generally speaking, obtain your fuel (esp high octane) from a source which has the greatest throughput (i.e. the 'freshest' fuel which hasn't been sitting in the tank a long time)

It all comes from the same place, just different additives, BP 98 comes from Singapore as well as Gull 98.

Probably dreaming that the is a difference as even the local air pressure , altitude and temp will alter power ratings

Caltex has little men that clean your engine in their petrol, so I'd say theirs is best.

Put it on LPG, 105 octane

Caltex and BP are the same real petrol, Z is a bio-fuel so has ethanol added. In saying that we use a lot of BP 95 and find it changes in quality quite a lot unlike the 98 which is quite stable.

Is Gull 98 a bio-fuel with added Ethanol or does it pump as it is imported.

" Z is a bio-fuel" Not according to the Z website

In some US states the same "rated" fuel changes to suit outside weather, mainly in places were it can be -20 to +30 degrees. In the cold won't start or too hot goes off.

I used to unload oil tankers at Seaview near Wellington once the tanker started pumping and the correct valves were opened ,the petrol went to the storage tanks of the following oil companies mobil,shell ,caltex,,bp all recieved the same petrol you might wonder where and when the additives are added

ethanol is the stuff with e on the fuel and should be avoided its gull who sells ethanol fuels . Gull Force 10 its 10% ethanol a sure way to destroy any engine and fueling system unless its a flex-fuel vehicle and even they can suffer problems when you get a ton of water in your fuel tank . ethanol binds water its how you test for amounts of ethanol by adding water shacking the fuel and then mesuring how much more water you now have , as ethanol binds to water and seperates off the petrol.

Yes, but those little men can get stuck in the injectors.
BTW, the "little men" additive will not have anywhere near the energy density of raw petrol - therefore less power per litre.

Did a lot of testing with various fuels/octanes some years ago after 'playing' with different zorst systems. I found Shell 96 (now 95) was the best all rounder, and still is. BP feels flat, Caltex is uneconomical, Mobil is almost as good, but not quite. Gull up here doesn't have 95 anymore.
