"premium" fuels seem unpopular on this site, and particularly I've taken the advise not to use them in my Swift VDI. It's a first diesel for me (pwnership at least, I've driven others) so advice is really useful.
But, if everybody is advising against premium fuel, what is the point of it? What are the oil companies selling there? Is it just a marketing thing?
I used to put higher-price, higher-octane petrol in my car in UK: the mileage was noticably better, and it worked out less per mile than the lower price. Either was acceptable according to the car manufacturer. |
