I am very please with the performance of my new Leon, but just wondered if anyone was using Super Unleaded in their 1.4 TSI rather than normal unleaded and if there were any tangible benefits?
I did hear some time ago that Super benefits engines with a power output ratio of 100bhp per litre or more, though I don't know of the truth in that as it potentially goes for most turbo engines these days yet most have 95 inside the fuel flap.
I use super unleaded every 4th/5th tank - just for the cleaning side of things. main difference is in my wallet, nothing noticeable on the road
Just use the standard 95 octane, can’t say I’ve been tempted into a higher fuel grade since the comparison is normally nill to minimum.
