I use Engen for the past 2 years.
The main reason is because of the e-bucks. Service seems ok. Where I drive to, there is always a engen garage. :=):
Ps: When we did the VW advance driving course in Kyalami, The instructor (apparently worked for Top Gear UK) said that BP is the best fuel no doubt. It gives the best performance / consumption etc. Maybe it's because BP is VW's sponsor??? so they would obviously recommend using BP fuel....?? And many people were aggreeing to this?? I don't know...I'm happy with Engen. I throw it in all my vehicles.
Here is a e-mail I got: "TIPS ON SAVING FUEL"
Petrol is becoming more and more expensive!
My line of work is in petroleum for about 31 years now, so here are
some tricks to get more of your money's worth for every litre.
Here at the Marian Hill Pipeline where I work in Durban, we deliver
about 4 million litres in a 24-hour period thru the pipeline. One
day is diesel
the next day is jet fuel, and petrol, LRP and Unleaded. We have
34-storage
tanks here with a total capacity of 16,800,000 litres.
Only buy or fill up your car or bakkie in the early morning when the
ground temperature is still cold. Remember that all service stations
have their storage tanks buried below ground. The colder the ground the more
dense the fuel, when it gets warmer petrol expands, so buying in the afternoon
or in the evening....your litre is not exactly a litre. In the petroleum
business, the specific gravity and the temperature of the petrol,
diesel and jet
fuel, ethanol and other petroleum products plays an important role.
A
1-degree rise in temperature is a big deal for this business. But the
service
stations do not have temperature compensation at the pumps.
When you're filling up do not squeeze the trigger of the nozzle to a
fast
mode. If you look you will see that the trigger has three (3) stages:
low,
middle, and high. In slow mode you should be pumping on low speed,
thereby
minimizing the vapours that are created while you are pumping. All
hoses at
the pump have a vapour return. If you are pumping on the fast rate,
some of
the liquid that goes to your tank becomes vapour. Those vapours are
being
sucked up and back into the underground storage tank so you're
getting less
worth for your money.
One of the most important tips is to fill up when your tank is HALF
FULL.
The reason for this is, the more fuel you have in your tank the less
air
occupying its empty space. petrol evaporates faster than you can
imagine.
Petroleum storage tanks have an internal floating roof. This roof
serves as
zero clearance between the petrol and the atmosphere, so it minimizes
the
evaporation. Unlike service stations, here where I work, every truck
that we
load is temperature compensated so that every litre is actually the
exact
amount. Another reminder, if there is a fuel truck pumping into the
storage
tanks when you stop to buy, DO NOT fill up-most likely the
petrol/diesel is
being stirred up as the fuel is being delivered, and you might pick
up some of
the dirt that normally settles on the bottom.
Hope this will help you get the most value for your money.
