Quality of Petrol

[vectra.lee]

Just wanted to start a discussion based on what I noticed.Partly because I love my Veccy, and also because my Veccy asks for PULP, I've avoided using petrol from those individual service stations with names like Ezyway, Enhance etc...Since I bought my Veccy in March this year I've always used PULP 98 from Caltex Woolies, thought I'd save $2/fill.The question I wanna ask really comes down to a debate that I've read about before: Is PULP 98 really better than ULP 91 or PULP 95?However, my question is slightly different.I'm not really looking for statistics, because I think as driving enthusiasts, we have a feel for our cars and so we're capable of making our own judgements.Yesterday I tried Shell's V-Power and felt a difference compared to Vortex 98 from Caltex.If you're a Shell user, have you noticed this yourself?Basically, what petrol do you prefer and have you experienced any differences between Shell, Caltex, Mobil and BP?

i'm sure this topic has been covered a few times in the past.

either way though. I only ever run on BP 98 unless its unavalible in which case i'll use mobil 98.

I've been running Shell 98 but have been recently advised to run the BP Ultimate. The only reason being that it will burn cleaner. Only downside compared to the Shell 98 though is that at very hot temps with the BP Ultimate, the engine may retard slightly before what it would if running the Shell.

The only time your likely to see these temps though are when your on the track.

I'll get it wherever I can, as long as it's 98.

I'm sure I've read somewhere (but now can't find a reference) that retailers in each specific area all get their petrol from the same source anyway to cut down on shipping costs - so there is essentially no difference in the petrol available between different brands in a specific area.

There is more variability with Ethanol based fuels. The ethanol content can vary - suppliers reduce the percentage at certain times of the year (and also recently due to cyclone inspired lack of supply). Only one chain (AFAIK) insists on mixing their own blend (obtaining the petrol from the area supplier, but using their own ethanol supply), and can thus guarantee the percentage is correct. This is why stations are often reluctant to quote an Octane number for Ethanol petrol - or quote a lower one than a true 10% Ethanol blend would give.

Another issue with ethanol is that it can hold water in suspension. So contamination of ethanol petrol with water isn't anywhere near as obvious as with non-ethanol blends.

Pretty sure BP and Shell get their base petrol from the same place, however it's the additional cleaning agents etc that get added to it that make it slightly different.

I think there's a few fairly major chains who are missing from the poll. I use one on a regular basis, and I've had to tick "Random Individual Business" despite them being a national chain...

If it's not on the poll, just click the last one and say who it is

Okay, the one vote for 'random individual businesses' so far is actually for United Petroleum.

Seat of the pants performance testing for differences in fuel is notoriously unreliable, no matter how much of an enthusiast you are ;-)
