E10 fuel in a vrs

[02VRS]

I’m sure this was well dealt with last year but just wondering peoples thoughts and experiences a year on. We’ve only just switched to e10 this week over here and I’m still running on my last tank of e5. It seems that they say my 02 vrs should be grand on e10, but I’m a bit sceptical and wonder would I be better sticking to e5 super. Cheers in advance 👍

Once you use a tank of E10 95 ron you will know yourself if you feel or notice any difference from what you are using now.

 

When you say stick with E5 super, is it just 95 Ron E5 unleaded you use now or is it E5 Super Unleaded 97 or 99 ron?

Not exactly scientific but when I switched to e10 I noticed a drop in mpg compared to the old e5 so I decided to try some super unleaded and compared fuel consumption over 2 tankfuls, the first e10 then the 2nd 97 Ron Sainsbury's super unleaded and the results were that I got better consumption with the SUL which more than offset the added cost so have put Sainsbury's SUL in ever since. I've got a 2018 mk3 vRS 230

Wasn’t wanting to use e10 in it if it wasn’t suited to it, had heard tales of it damaging fuel lines etc. Have still been using the 95ron as e10 has only been introduced here within this past week.

Mine seems fine on E10.

 

It's always been noticeably better on V-Power though (even well before E10 came in). Can't say I've noticed any difference in fuel economy with 95 RON E10 compared to the old 95 RON E5.

Cheers just went with some e5 super there as wasn’t sure whether to chance it or not 👀 the govt site said it should be grand on e10 but I’d rather hear from actual experiences. I was more worried about it damaging components than mpg as I don’t do big miles in it.

2 days on super unleaded and the EML has just come on. Maybe just a coincidence 🤷🏻‍♂️?

Time to check all 4 spark plugs for condition / gap unless recently checked.

Probably just a coincidence. Can you read the codes?

[02VRS]

Plugs have around 4K on them I think, hopefully get the chance to get it read tomorrow 🤞

Boost leak between throttle and turbo

Forgot to update the thread. O2 sensor was away and a wee breather coming off the rocker.

 

I’ve been using the E5 super unleaded but imagine that it’s harder in fuel 🤷🏻‍♂️ Is everyone else just using e10 since the switch over with no issues?

Hey guys-I have just acquired a 2016 Octavia VRS and on my way home filled with 91 Octane. Only then noticed that requires 95 (or higher?). Will this cause probs in the long term (using 91 v 95).

This is in the mk1 section and a 2016 car will be a mk3.

 

I'm not sure if it will cause any problems but I would fill it up with premium unleaded next time (97 RON+) then use 95 RON+ in future.

Thanks for that.😉
