So I've been using E10 or unleaded since I bought my car in October last year.  Not sure if switching fuels will damage anything.  I just go with whatever is cheapest.  Currently, both are hovering around the $1.40 mark.  Both have been as low as $114 in the past few weeks.

At the PD launch last year, their technical people were adamant that E10 was fine.

Hi,
Owners book should stipulate what types to use and the level or % ethanol blend,
Aus fuels are pretty good, most ethanol is 10 % blend  (85% is available  at specific servos).

( you're a quick typer    )

I've regularly used e10 in my last few vehicles including the new SR without any obvious ill effects. I've now done over 21,000 kilometres in 9 months!

Good to hear.  My i30 Active manual gives a categorical warning about Methanol in the fuel and infers that ethanol blend needs to be free of methanol.  Guess its a South Korean manual so it would be encouraging to hear that Hyundai are OK about Ethanol blend up to 10%.

10/10 hire cars agree e10 is fine.....

Saw this Can my vehicle operate on Ethanol blend petrol? | Federal Chamber of Automotive Industries

it stated

"Fuel Injected Engines

In addition to the issues mentioned above for carburettor equipped engines, the use of ethanol blended petrol in fuel injection systems will result in early deterioration of components such as injector seals, delivery pipes, and fuel pump and regulator.

Mechanical fuel injection systems and earlier electronic systems may not be able to fully compensate for the lean-out effect of ethanol blended petrol, resulting in hesitation or flat-spots during acceleration.

Difficulty in starting and engine hesitation after cold start can also result."

Hence I'm not sure i would want to use e10 now that i read that.  The part "early deterioration of components" sound scary.

The state motoring bodies seem happy to recommend it.

I may be imagining it, but I think my car might be a bit zippier on 91 than on E10. My last tank and this one I just got are 91.

I thought E10 being 95 octane might actually boost performance and sometimes in the past with my Calais for example I thought it did.

Because it is only 1 CPL cheaper in Tassie (not 4 CPL as in Victoria) I think I might use 91 from now on.

After reading that I30 SR manual, it actually said OK to use 91 RON or E10.  Yet all the other websites got other information as well.  When in doubt, go with the instruction manual

True, but for the sake of 1 CPL I'm starting to think 91 might be the better option. Not going to pay something like 17 CPL extra for 98 though.

My mechanic was adamant that I shouldn't use e10 (and no car should unless specifically mandated by the manufacturer). Apparently ethanol molecules bind with water molecules very easily and that's where the problems lie.

I reckon he's right.
But you should be aware that Hyundai has specifically said the PD is suitable.

Engineering Explained recently had a segment on .

In summary, ethanol does not cause engine wear. However, it has less energy content. It also absorbs moisture from the air which is an issue if sitting around for extended periods of time.

The other day while fueling up my i30 with 91, i noticed inside the fuel cap it got a label 91 or e10.  So that mean Hyundai OK with e10.

Yet, I'm going to stick to 91 for now .  Water and fuel don't mix and if that is what e10 "encourage" mixture of water with fuel, then I am staying away from it.

Yeah at the launch of the PD i30 they told my Proxies (I was invited but had other commitments) that E10 was fine. As you say the sticker even says so. I haven't kept a car outside warranty for ages so could quite safely use E10 but as only a cent per litre saved not a lot of point. It's 4 cpl in Victoria so would probably use it over there.

Good short video on the pro / con of e10.

Touched on engine wear and circumstances where E10 is not advisable.

doh was putting the same link as above.  I think i need to finish my whiskey and go to bed

Umm, I think it's the same video as tla shared recently!

Hi guys...

Here in Brazil all petrol only cars uses gasoline with 27% of ethanol. So, it's OK e10.
