I would welcome comments on this...how to save money on fuel costs.
I fill up my car at the local Woolworth servo in Noarlunga. The difference in price between the Regular Unleaded (91 octane unleaded petrol) and the Vortex 95 (95 octane premium unleaded petrol) is about 15 cents.
I was told by a mechanic to use the higher octane even though it costs 15 cents more...roughly 10%
For the past few months I have been paying the extra cost per litre and seeing what the difference is with the milage.
I have a log book and can work out how far I was travelling on the cheaper 91 octane compared to the 95 octane.
I used to get 400km per tank (Kia Carnival 3.6l) with the 91 octane fuel.
With the 95 octane I get 500km per tank!
I have tried not to alter the way I drive..have worked it out over longer and shorter trips...and I still get 20% more milage from the higher octane fuel.
10% increase in price for a 20% increase in milage! There's also the better perfomance as well (I am not a hoon!)
Any thoughts or comments from others who agree or disagree would be good? It certainly seems to be saving me money.
