Big Ron

Going back a while, using Optimax came up and the general consensus was that while costing more than standard leaded the larger Ron value (or whatever the technical term is) does increase performance. Evo magazine last issue has a test and Honda Civic Type R seemed to like the stuff especially in the higher gears. Sainsburys, my local purveyor of choice for convenient re-fueling and collecting discount points 'does' I noticed this morning have another pump that I had barely noticed before - the super unleaded 97 Ron over the standard 95. Its only about 4p more per litre, so what with my 3p off a litre discount coupon, I should commence using this pump and my ECU (?) will adapt after a couple of tankfuls. Then I add some Millers Octane Plus and it goes even quicker right? [img]smilies/smile.gif[/img]

Optimax and Milers Octane plus is 99.3 Ron,and is also a decent Mon-similar to the old five star.(Ron isn't the only measure of fuel).

The Ecu will adapt after about 3 tankfuls but you may see a difference sooner.Its quite noticable unless you drive like your grandma.

Is that a yes to the pump labelled 'Super' then Dave?
What is the number for that Millers rep. you posted some time back - I can't find it.
Don't know about driving like a grandmother, but I drive my Alfa like a mutha - goodbye Mr Golf you bland if well constructed kitchen appliance.
Yeah. [img]smilies/krakrani.gif[/img] [img]smilies/biggrin.gif[/img] [img]smilies/krakrani.gif[/img]
