Why fuel company say their e10 have minimum 93-94 octane level? Is it true and why not reflect in the fuel consumption? Does e10 bad for your car (non premium)? Just want to have some idea.

Welcome to the new look VWWatercooled
After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.
Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before.
We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

A1. Because it has 93-94 octane.
A2. Fuel consumption has nothing to do with octane.
A3. Google is your friend.Ethanol fuel - Wikipedia, the free encyclopedia

1. Regular unleaded: 91 RON.
2. E100 (i.e. 100% ethanol): varies from 109 to 129 RON depending on who you quote.
3. Regular unleaded E10: varies from 93, to less than 95, due to 10% ethanol content.
4. Market price of ethanol is simply less than petrol.
Conclusion: E10 costs less despite having a higher RON.

Basically, the more you can compress the fuel before igniting it, the more efficiently it burns, but only up to a certain limit before it starts to ignite by itself (potential engine damage!). The octane rating of a fuel is what determines this limit.
Whether that leads to more power or less fuel consumption depends on your engine being able to recognise and take advantage of higher octane fuels.

Don't get me started on US RON vs rest-of-world RON vs MON
RON values are like wang sizes - bigger isn't better, its all about the bang. Quote me on that one tooMY02 Bora V6 4Mo|Matte Black plastidip|VTDA|R32 Exhaust|R32 dampers and springs|TT pedals|R32 steering wheel|17" 8L S3 rims|R32 sways|Blue Haldex|EBC reds
