Now it’s 11 Cents More for Premium

It wasn’t that long ago that I posted up an article pointing out that the differential between the cost of 91/92 RON regular unleaded and 95 RON premium unleaded had gone from 8 cents to 10 cents. In fact now that I check back through the postings on my site I see that it was on 2nd of April that I put that note up on the site.

So tonight when I pulled into my regular Shell service station and filled up ready to take off tomorrow for site I noticed that regular unleaded was $1.369 and premium was $1.479, a difference of 11 cents!

So now let’s see. It took them about three years to go from a 6 cent differential up to 8 cents. Then, as far as I can work out, it took them about 18 months (1.5 years) to bump the differential up to 10 cents. But then it has only taken three months to push the difference up again, albeit this time by just 1 cent and not 2.

So now premium unleaded, which I have to use in my 2005 turbo Subaru Forester, is 50 cents per imperial gallon more expensive than regular unleaded.

Anyone got any bets on how long before they add on that extra 1 cent to make the difference a nice even 12 cents?
