Preferred petrol?

On my way to pick up my 2.2 brera (2009).

Seen people mention preferred fuel and wondered if others have preferred fuel?

Esso ultima? Shell vpower? Or just cheapo fuel?

I use regular 95 plus a shot of Millers additive.

Its only about 13 quid from Halfords. I tried using 97 fuels, but 95 + Millers seems the same.

Anything at all (in the UK) works just fine. Just stick in whatever is cheapest; you'll soon find things to spend the difference on.

Exciting day!

I use either Shell or Esso premium fuel but only because you get double or treble points which I use to build up my British Airways air miles....

From the factory it is mapped to run on 95RON, so that is all you need.
Using higher RON may even result in less power if the ECU can't advance the ignition enough to make use of it.

My Brera was remapped while I've been using it. Don't know if that takes care of any problems...

Possibly.
You can gain power by running more ignition advance, but to keep that reliable you'd need a higher Octane Petrol, which will be why some mappers will say to only use Super Unleaded after their remap.

To use Super Unleaded with the std map may just result in a lighter wallet...
saying that though, my little 899 Cinq runs on 99RON as it knocks on 95RON and I don't want to touch the tiny little old screws that need to be loosened to adjust it!!

Tesco Momentum runs 99-Ron produces less soot/carbon on the exhaust tips than standard pulp, so it must be keeping the injectors clean. Much better throttle response too. I actually preferred it to V-Power at 1.12p a liter

I put half a tank of shell vpower as it was on fumes when I picked it up. Nothing to compare it with, being my first drive, but car reported 32mpg on the 70mile journey back.

What a journey like ?

32 mpg over 70 miles is about right. It must be pretty healthy.

Have you got a list of things to fix and/ or improve or is all good?

I use Shell or BP, just the 95 although not BP in the Spider as when trying to fill the car, it will only fill to below 3/4 full? Tried a few BP stations, all the same. Don't have a problem with other peoples pumps.

I think it has a rear wheel bearing on way out, can hear it above 40? Doesn't change pitch, just quietens down when slowing?

Other than that, seems all good but considering having it all looked over anyway whilst it's new to me.
