E10 unleaded,does it work?

[Tigga1]

has anyone tried the E10 fuel in the Tig, does it work?
it's a big price difference, so may be worth it.

Although, maybe these german engines are very particular...:-]

Forget it Tigga if you get the remap - Ultra premium (98 octane) only sorry.

I read on a pump that it increases fuel comsumption.

Thats the alcohol content

This question is well timed. Last months RACV magazine has an article discussing the pros and cons of E10 fuel.
In summary they found that you will use more E10 fuel compared to RON91. However the consumption difference is far greater than the savings. I think the price difference is about 4 cents. So in short the article argues that you will spend more money filling up with E10.
I would also check whether the Tig can actually take E10.

VW recommend min of 95.

VW recommend min of 95.

that's why my question, coz it says 95Ron at the E10 pump, and is about 24c cheaper than 98Ron V-Power...

Does it? Which e10 is that?

If you look up the Tech data sheets of the big4 they actually quote their E10 as being in a range between 92-94ron. The only supplier that I'm aware of that claims 95ron is United for their e10 offering (Boost95?).

Why is it 24c/L cheaper? Generally the e10 save is 3c on ULP & 98ron is a 15c premium to ULP so the difference is 18c.

What is most important is how many c/km it costs you to run the engine. You will only find that out if you keep meticulous fuel records & try each fuel type for a minimum of 2000km.
In the case of my Skoda, the reduced fuel consumption using 98ron offsets the price difference between 95ron & 98ron, therefore it costs me an extra $50 in 25,000km to run 98ron with all the additional benefits of better power down low, more powerful detergent/additive pack, etc.

I guess if you were really keen on trying to "save" $5 a week you could alternate between e10 & 98 with fill-ups every half tank.

VW requires 98 Premium at all times. (Even though the filler cap says 95). I have an email from VW Australia where I asked about ethanol fuels and they replied that:

1. Anything with more than 10% ethanol will void your warranty.
2. Anything less than PULP (98 RON) will void your warranty.

They were quite specific about that .......

So, do not put anything but 98 in your TSI. In a pinch run 95 but fill up with 98 as soon as you can afterwards.

I posted this email up in the Polo section about a year ago, if you want it go look for it.

Don't bother looking found it .... http://www.vwwatercooled.org.au/newf...ell+100&page=5

Sharkie, thanks for your insights, really good.

Brad, touchee...

you' ve both answered my question, and I will fill up 98RON whenever I can, hang the expense...

When you buy the Tig, obviously it's not about 5c here or there, it was more curiosity when I found out that the E10 claims 95 Ron and filler cap recommends 95...coincidence...?

and, as Clip says, if you go with the remap, surely anything less than 98 is out of the question...!

thanks guys, having my car "ascertained" tomorrow... that is, whether it's in the "code"...

let you know

Ethanol has a lower calorific or burn value than petrol, so a mix of it will give you less oomph despite it matching the octane rating which basically is a measure of how much the fuel can be compressed before exploding.

I have a Honda Accord Euro, which takes E10. I could feel no difference in power (compared to 98 RON) or fuel consumption, although that is not scientific. I am sure it would be the same in a Tiguan.

NA compared to turbo? Is the Honda direct injection/Fuel Stratified Injection?

My FIL says he gets no difference in power or fuel consumption with any grade of petrol in his '98 V6 Camry - fair enough, he keeps fuel consumption records & according to him it doesn't have knock sensors.

In my 1.8TSI e10 affects fuel economy by almost 1L/100km (about 10%) which nearly offsets the smaller c/L

Hi All,

Just want to share my opinion on this topic, because I am in the same boat and try to find a logicalanswer.

I have also wrote to VW Australia to ask then whether my Tiguan TSI engine can handle the E10 fuel or not, I got the similar answer, which they told me 98RON recommended. But this is not a acceptable answer because,

1. Both the car manual and fuel tank label clearly indicate min 95RON is required. – How can VW Australia given a confused answer like this?

2. E10, VW Australia said no E10 is allowed in the TSI engine, but why Federal Chamber of Automotive Industries says YES for E10 on all VW fuel injected models post 1986. link Can my vehicle operate on Ethanol blend petrol? : FCAI


I have tried to ask VW Australian for explanation why they responded to this issue are so not match their own manual and government resource. I haven’t no heard a thing from them for more than 2 yrs.

Big VW: are you talking about e10 (94ron) or 95ron (no ethanol from the big names)?

This probably answers your question best:

Volkswagen All Volkswagen petrol engine vehicles will operate satisfactorily on E10 but Volkswagen does not recommend it.

(got it off the internet so it must be true).

I can see the value in running 92E10 compared to 98ron if it makes no difference to fuel consumption or power - the extra 18c a litre is significant if there's no advantage but 95ron is only 5c (4%) cheaper than 98ron. What's 4% of your total fuel bill? About $100/year if you do 25,000km. That's what it costs me. That's like 1 less beer/coffee per week. My missus would blow $100 every month on ill-considered clothing purchases so I'm guilt free on buying 98ron.

BigVW: If VW haven't got back to you after 2 years then your request is probably in the round file just under the desk.
