Hi All, I'm a 2011 Superb TS118 owner in Australia.

 

Have noticed some petrol stations are now supplying E10 RON 94 fuel, as their new "middle" option.  Standard RON 91 and Super Premium RON 98 are the other options. 

My 2011 TS118 Superb states it needs RON 95.

 

I've run about 2 tanks of this E10 94 through it so far with no noticeable issues, but I'm concerned more about long term damage.

 

Can't find any info online (other than a similar question in the Fabia section here), and my manual was written before this fuel was available down in Oz.

 

Anyone know if this is a suitable long term fuel for my Superb?

 

Would not recommend it.

1) In the manual it states that 95 Octane is the minimum, same on petrol tank cover.

2) E10 is just 91 Octane with added 10% Ethanol added and 91 Octane is pretty rubbish stuff, relatively low on cleaning detergents and high on sulphur 91 octane is 140ppm and 95 octane is 40ppm. European fuels are just 10ppm.
