Confusion Over Correct Unleaded Petrol To Use in 2012 Hyundai Imax

Dougwe · Chief one feather

Hi Vic, I ran the Prado on 98% for the last 18 months of it's life with me, unless I couldn't get it. Ran much better than 91% and better economy but not sure if it worked out cheaper over all.

My daughter here in the tropics runs on 95% and reckons her Camry runs much better than 91 or 98.

I was told many moons back that the high octane also keeps your injectors clean.

Why not run a 10% ethanol blend, save money and get a little extra boost.
Shell is 94Ron and United is 95Ron.
Don't know about the other brands, but the servo operator should (Ha Ha) know.

Vic, the telltale sign with 91 and 95 is wether or not you can hear the engine pinging. If it pings on 91, you may need to use 95. Had a chat with a knowledgeable person regarding various fuel grades. The bottom line from his pint of view was, using 98 around town is a waste of money. You only get value from 98 on highway use.
I have used ethanol blend in the name of 'green'. Whilst cheaper at the pump, you end up paying for it via greater fuel consumption and no noticeable boost.

Thanks Doug, Ozjohn and Larry. Food for thought.

I was also told that 98 was overkill and a wast of money (the most expensive too) so have avoided that.

Not sure if I could hear any pinging as my hearing is not the best, flat out hearing the blinkers (wish they would make them with volume control so you could make them louder! LOL)

Very unlikely to hear pinging with fuel so close ie 95 and 91 especially with auto trans, which I assume it is.

Thanks Baz, yes it is auto... blankstare

Vic41 you could fit a beeper to your blinkers if you can't here them.

Thanks Lance, I'm just about beepered out, I have reversing sensor audible beeper (for objects) and outside audible reversing beeper (warning to others I am reversing), but worth a thought as I would be driving so a bit different to reversing.... smile

You will not hear 'pinging' in any modern engine - most are fitted with "knock sensors" which detect pinging and instantly retard the ignition etc to stop the pinging.
The imax is designed to run on 91ron - not premium. Using premium will have no advantage and cost about 15c per litre more.

Gday...

This is not Hyundai Imax specific, but is a very good description of the petrol 'types' available and their usage.

One would expect that your Owner's Manual should be helpful in providing advice on the 'type' of fuel to use in your particular vehicle.

Perhaps the sticker under the fuel filler cap will be even more helpful.

This is the link from my first post on the thread that says Premium Unleaded Rocky, but I am getting mixed messages on the subject, see the specifications here; http://www.carshowroom.com.au/newcars/2012/Hyundai/iMAX/O6B12H

As I mentioned earlier not many small country servo's have Premium Unleaded so I have been using Standard Unleaded on my trips, topping up with Premium when able to.

Thanks for the tip and the other link John, it is very interesting. smile

Update: As suggested I looked inside my fuel lid and is just says simply "Unleaded Petrol" it give no indication as to what Octane, but I presume 91. My car manual says 91 unleaded or higher (95 or 98) but not E10 with more than 10% Ethanol and none with Methanol mix.

As said earlier car dealer workshop told me it needed 95 Octane, but the RAC said 91 Octane.

I will still keep asking around but in the meantime will probably just use 91 with the occasional top up of 95 for good measure. smile

Late model EFI engines should tune themselves.. If its a hot day pulling some weight?
It may pay to change down..
I modern engines ping ?? There's a tune issue issue . Restricted fuel filter, thermo fans not working etc??

Thanks Denis, and apologies for not spotting it, I must have jumped a couple of posts.

RAC WA also use Red Book to give their opinion on fuel, they said 91 ULP also. Mine is a 2012 model but I assume it would be the same.

This extract was from your link (for others info);

Fuel Type

Petrol - Unleaded ULP

Series

TQ-W

Recommended RON Rating

91

Thanks Mate, that will save me some money!!! (very happy) biggrin

PS: Just checked the 2012 Model using the link you provided, is the same as the 2013, Thanks again, Vic

Note: Part of the confusion is this link which says the same model uses Premium Unleaded fuel, see;

Just a final note. Looking at the Hyundai Official Website, it just says the Imax auto 2.4 petrol uses petrol (fairly obvious I would have thought) but no mention of type of petrol or octane rating in their download specifications.

I rang Hyundai Head Office and they said just use what is in the vehicle manual, which is petrol 91 Octane or higher (ie; 95 or 98). They also said ask your Hyundai dealer (well mine said Premium Unleaded, ie; 95) I told them this and also that the link shown at the bottom of my previous post says to use 95.

They had no answer for this but to say just use what the vehicle manual says (91) and when asked if it would cause any damage to the engine said no.

Talk about mixed information from different sources! So as far as I am concerned I will use 91, more available and lighter in the pocket...

So will 95 still be available? And will E10 be safe to use in petrol engines designed for 91? confuse

(in my case a 2012 Hyundai Imax)

Still around in WA, haven't heard any rumbles about it being phased out here yet.

Thanks AK, do they need any change in tuning or are they self tuning for the E10????

Aus-Kiwi · Guru

Yes they may go through more fuel if pushed on E10 let's face it work vehicles generally are!! ..EFI has sensors covering everything from air intake density, coolant, intake temps, tps throttle position, O2 sensor etc etc

Thanks AK! smile
