Can someone please clarify the position regarding which unleaded to use in this engine? I've searched the forums and find differing answers....
I was told prior to purchase that my '03 Avant SE would run on normal unleaded, which it does. But they filled it up (yes, I got a full tank of fuel out of a dealer) with V-Power. I've found that performance and economy are better with this more expensive fuel, so OK, I'll live with that. The owners manual (yes, I did flick through it) states that you should use 98RON unleaded, but can use 95RON if necessary (i.e. when you can't get 98RON) - but is it OK to use Tesco's Super Unleaded - I noticed it's 99RON.....?
One more newbie question - is it worth 'chipping' this engine? I don't want to set the tarmac alight or anything, it would just be nice to have a little more throttle response between 1500-2500RPM. Having test driven both petrol and diesel variants, I opted for the 2.0FSI over the TDI for many reasons (including cost), but it would be nice to plant it in 4th when leaving a 30mph limit and feel like I'm getting something from the petrol engine - there are times that I get nothing!! Also, there are times when it feels like the car really takes off - sometimes almost 'out of control', like it's making it's own decisions about how much acceleration I want - then kind of dies when changing gear. Maybe somethings not right? I did have a 'nox' sensor replaced under warranty to remedy an idle problem...........
