Where do you fill up?

I ask because our family's auto mechanic, I guy we've been with for 20+
years, is telling us Woolworths/Safeway petrol is a little lacking in the
quality department. He says the Coles/Shell fuel is better, but BP is the
best in terms of quality. Is there any consensus about this? Have there been
independent comparisons done?

 

Sounds like crap to me. How is 'quality' defined and what super scientific
methods is a grease monkey using to determine this?

 

Yes, they all contain carcinogens. Aromatic hydrocarbons and high exposure
to them are are bad.

All I was told was avoid discount places and small petrol stations where
the fuel might sit around and the tanks might not be as clean.

 

Not as clean as in contaminated, or adulterated?

Kev comments ?

 

ok how about when the shotbox transit did a fuel pump due to low quality
diesel

the diesel mechanic which had all the whizbang gear told me that they had
done fuel testing
on all fuels available and said to use BP 1st and Shell 2nd as when tested
they found these
to be more consistent in quality than the others

Quality being levels of ingredients that are supposed to be in fuel , octane
levels etc

either way i have changed vehicle and still stick with BP where possible and
find better fuel
consumption in the rodeo than other brands

YMMV

 

Not as well maintained and therefore not clean of the kind of rubbish
that might accumulate, entering during refills over time.

Not sure of the difference between contaminated and adulterated.

 

Contaminated is accidental, adulterated is not.

So how much did you pay for your BP shares?
Oh and feel free to post the results of said tests anytime you like. No
point arguing over heresay and conjecture

 

water , dirt versus added ethanol and other shit

 

local pub

 

i dont have any shares whatsoever , can fuel at any servo and costs me
nothing
since i have a work car with a supplied fuel card

I have the rodeo which does around 400k per tank and this for me is 2 days
driving

As you might expect i hate fueling every 2 days and hate to fuel any more
often than i have to
so i keep a close eye on how many kays per tank that i get

My experience with the rodeo is when i dont fuel at BP i lose 40K or so to
the tank

I have tried all the brands , all the octane levels to find what will give
me the furthest kays per tank

feel free to run your own controlled experiments

next time Bullly neglect to snip 'YMMV'

 

Go and watch your local Terminal plant, the Mobil one I pass each day to and
from work has Mobil, Liberty, independents, Toll and Caltex trucks rolling
out each day.
Caltex is Safeway so it must be the what they use in Melbourne there is only
one refinery in the west or Shell in Geelong to supply the petrol needs.

 

Really? What sort of whizz bang gear? They have a shop mass spectrometer
and 300 NMR?

So qualitative and quantitative?

I wasn't sure if you were suggesting not clean = water, silt, i.e.
Non-chemical additives, or, adulterated, diluted by the addition of other
aromatic or aliphatic chemicals?

It's been a source of discussion here in England for a while. Tesco
is a large supermarket here and owns a chain of petrol stations. Tesco
petrol is normally the cheapest of all of the suppliers by a couple of
pence a litre. Tesco petrol is also considered one of the lowest
quality even though the legal minimum octane rating of petrol in the
UK is 95 RON (Super Unleaded and things like Shell Optimax are
normally 98 RON)

It's all swings and roundabouts. To most people petrol is petrol. As
long as the car goes when they put some in they're happy. I think the
problem is that people with high performance cars will sometimes
notice that the vehicle runs a bit more sloppily on lower quality
petrol. I notice that my new Nissan Almira Tino 1.8 (certainly not a
sporty car) displays 'pinking' on some cheaper brands.

My Kawasaki says it runs on anything from 92 RON upwards (probably the
gloop that they sell in America?) so I just stick whatever's cheapest
in it and never notice any difference.

 

The first.

 

There was some small scale testing done a couple of years ago of a small
number of discount and name brand servo's.

The 2 discount chains ended up showing the lowest octane ratings for
each class of fuel (the differences were minimal however).

My main problem with the Supermarket ones is that they seem to use very
small litres!
I often get 50 litres into the 48l car tank or 23l into the 22l bike tank
and I even got 12l into the 10l mower-fuel can the other day.
I'm back to using Shell.
