Sedaj pa hodiva sicer tankat v avstrijo. Gor po nakupih, pa še povhen tank, ker je gor cena 1.46 evra za liter 95 oktanca.
Kako zaboga zmešaš vodo in bencin? Bencin ima manjšo gostoto kot voda, torej plava na vodi - tako bi tankal ali samo bencin ali pa samo vodo (pač odvisno od tega, kje v cisterni je sesalna pumpa).
Tole okrog bencina je en sam BS - razno nategovanje s tem, da 'motor dela boljše, če tankaš 100 oktanski bencin' ipd.

So, premium petrols are great and everyone should use them? Well, not quite. All engines benefit from the increased fuel density, and the cleaning additives. But the benefit from the higher octane rating is small on those engines intended to run on low octane fuel, and zero on those without knock sensors (for example Rover's 4-cylinder K-series). (Some engines are naturally not "knock limited" - the optimum ignition advance can be used at all times without knock occuring - and others are only slightly limited.) In keeping with the sceptical outlook of this website, I do feel that the marketing for such fuels, by the use of wording such as "up to", can give a misleading impression of the average improvements to be expected - and the Advertising Standards Authority agrees.
