If you are flying up and down the motorway I would say supermarket fuel is fine as the car is up to operating temperature and the engine is running freely and the exhaust gasses are being forced out as to say at a very high rate. I know many taxi driver (who do up to 60k a year and have very strict emission tests from the council and they almost run on pure injector cleaner when they go in for testing at the council) and they say Morrisons and Asda diesel is particularly smokier than other brands. Its all a matter of how you feel but I never get this problem when I visit people who use Shell or BP etc.
Many on here use supermarket fuel and use Millers etc or Redex to keep their engine "clean" which is the same as using premium brands that already have the additive in. No problems when you use it fine why would you change? Its al down to individual experience.  |
This is basically it.
Also, just because one person's car has been fine and the driver does not notice any difference between different fuels when driving the car under their conditions does not mean that there will be no discenible difference when the car is driven under a different set of conditions.
Those who state with absolute certainty that different fuels do not make any difference and expres views such as "placebo effect" are actually highlighting a limitation in their understanding of the basics.
Or, maybe, some of us just have better tuned sences?
