91Ron, 95 Or 98Ron?

[ARTZ]

here mate straight form the owners manual of a 2010 infinity..its all i could find...

[The Max]

Yes, so keep the use of 91 to an absolute minimum on the basis of sheer desperation (i.e. roll into a regional area where 98RON is not available) and since we don't have 96RON in any station I've come across in NSW, skip it and go to 98RON instead to realise the full capabilities of the engine. Furthermore, avoid E-85 since the components weren't designed for it. E-10 is their recommended maximum percentage of ethanol permissible.

Again, not a hell of a lot of choice for what the vehicle was intended for. If you don't want to run the 98RON fuel, it's pointless buying the vehicle. We may have to agree to disagree on this.

[ARTZ]

hey i'm happy to be proven wrong if I am....

now go here and see a list of manufacturers who support the use of e10

http://www.fcai.com.au/environment/can-my-vehicle-operate-on-ethanol-blend-petrol-

and any Nissan post 2004 is e10 compatible...

now I imagine maybe that only covers Australian built cars..but isn't a v36 very similar to a 370z which is sold here...

[colin.ssc]

Would support E10 just means the car is able to run on E10 but doesn't mean you should run it. Just like how it say you can run RON91 but no WOT

[The Max]

Not sure what it is I'm trying to prove you wrong about. All I'm saying is that the vehicle is made for 96RON as a minimum and we shouldn't go to anything less than that. What I was disagreeing with you about was your comment about the rationale behind the availability of different fuels being driven by consumer choice.

We can both agree, in accordance with the manual, that 91RON is not ideal for the vehicle and should never be used unless in a moment of desperation because of nothing else being available.

Then as far as the difference between 95RON and 98RON is concerned, you say it's insignificant, I say 95RON is outside of Nissan's specifications as far as performance driving is concerned, and the V36 is a performance car. Being an engineer (albeit electronics), I'm all about specifications and working within those specifications, in order to realise the full potential of the product in question.

As for the information given by Nissan to FCAI about the suitability of E10, when you pit it against the owner's manual for the G37, there is no difference. They recommend a maximum ethanol percentage of 10%. This is also something we can agree to.

However, this is about the limit of my knowledge and I would hazard a guess that just because it has 10% ethanol, doesn't mean the fuel is limited to an octane rating of 95RON. With all the additives they can throw into the mix, why not make it 96RON? Is it perhaps that the performance and/or price difference then between 96 and 98 isn't as significant as between 95 and 98? Like I said, that's the limit of my knowledge. So I just look at the manufacturer recommended figures and work within them. If I'm told a minimum of 96, be it in a 10% ethanol blend or 0%, then I'll throw in the 98 and run with it until the car drops dead. Why? Because as much of a throwaway item as a car may be to you, to me, I'm a bit more of a sentimentalist and would not have upgraded from my old J30 Maxima to a V36 had it not been for the unfortunate collision all those years ago. I put the good stuff in to keep getting the good stuff out for as long as it can.

But I didn't chime in to argue the finer points between 95 and 98. I chimed in to argue that this isn't even a topic worthy of discussion for these vehicles given that if one can afford a premium car, which is what these are, then one should afford the premium fuel, otherwise they should have bought something else.

Problem is Artz, many of our servos have a "up to 10% ethanol" fuel for e10. So really, without the sensor (and I know you love the sensors ) you wouldn't know what your putting in. Could be anything from 91-95.

I know you and Scotty love to get together and have a fap on the e85 pump...

[ARTZ]

Yeah maybe I have my wires crossed...it seems the euro standard is 95ron...maybe Japo standard is higher.

But I totally agree, if the manual is recommending 98 then yeah you should be running that..

Again, back to the o2 sensors... It doesn't matter what the ethanol percentage is between 0 and 10%, the car will run fine so what does it matter? All fuel will have some percentage of ethanol in it, some more than others. How would you know otherwise? It won't matter soon, the minimum will be 10% then slowly get higher as the price of dino fuel goes up.

If a car has been designed for 10% ethanol use, then it is fine for more percentage imo, as long as it's tuned for it. Ethanol isn't corrosive in late model cars from my extensive testing, no more than petrol anyway.

If you saw how clean my engine internals were when I pulled it down, you would be fapping too.

[niZmO_Man]

95-98 ..is there really that much difference? if i can get 95 octane e10 for 1.30$ a litre when 98 is a 1.60 a litre...thats at least a 15$ saving on a full tank of fuel...if i am using a tank a week thats maybe an 800$ a year saving...thats my registration paid....add to that ethanol will help clean your fuel system as well as any additives they put in 98....I don't see the problem except maybe 2kws and a bit less range..and i dont use 15$ worth of fuel in 50kms...

if e10 was the only fuel at the pump, everyone would run it ..but people like choices, this is the MAIN reason we have different fuels...if water was the only drink in the fridge, you would happily drink it but no, go to a servo and there is 4572 different drinks to choose from...why? because peopel like choice...truth is it really makes no difference what pump fuel you run because your car was built for its tolerances in mind......true some fuel might make your car live a little longer, but alot of people couldn't care care less...cars are disposable...

people like choice

Some points I agree with, some I don't. As mentioned, you don't know that every E10 is 95RON (Mobil/7Eleven list them as 94), so treat them as 91RON ("up to 10% Ethanol"). I wouldn't risk running an engine that's designed to run on 96RON on anything less than 96RON, but hey, your money and car. I sure as hell won't be buying your vehicles off you if you consistently run E10 in a standard Skyline.

But like a lot of people, saving money is the key here. So choice is a good thing really. In NSW the government tried to get rid of 91RON and then later changed their minds. I don't run E10 on any cars I fill up. Either put up with putting 98RON or sell your car and buy a little commuter car designed to take E10 so you can save even more money! Or you can fill up on cheap days where the price of 98RON drops 10-20c (it's usually 15-20c more expensive than E10).

Wasn't the O2 sensors that was my issues, it's the RON.

O2 sensors change ignition timing now too?

Would you rely on a fuel that is advertised as 95oct, but with a caveat that it may be as low as 91oct?

[scotty nm35]

I only said e10, there is no way I would say to use 91, or 95 for that matter, can we forget the low grade fuels and admit e10 100 octane is a great fuel, and e85 or straight ethanol is even better please?

Of course your car was pinging, the fuel was just too low in det resistance to handle turbocharging an NA engine. Even ethanol pings in situations like that if you lean on the tune.

[V(35)Powarh!]

fyi the highway patrol cars (fpv wiith worked engine?) the cops used for pr and community work, fcked up cause an officer filled it up with e10 bhahahah cost them $5k to fix up the engine

Sorry man, I've never even seen E10 100oct up here, but, I NEVER use united servos.

I was referring to regular poo grade e10

We just don't have the access to e85 that you guys do.

I never said i run my skyline on e10 did I..

I said I run the wifes 2004 accord on e10 because

1 it is cheaper

2 it is her car I barely drive it and

3 it is perfectly safe to do so

now I may be at fault here for comparing a later model nissan v6 to an earlier model honda V6...or maybe honda just build better cars that aren't so temperamental to minor octane changes.....

as for my skyline it always got premium because I noticed the difference and it was running extra boost.....

It is a turbo car after all and as with any turbo, higher octane makes a noticable difference..

But i do believe they were designed in the 80s so Im sure they run fine on 91-95 octane fuel. and I would be perfectly comfortable to do so....I mena all it says inside the cap is "unleaded fuel only".. the only real benefit of 98 is a slight power increase...sititng on 3-4000rpm day to day driving isnt going to make a lick of difference to a standard boost skyline....

back in 86 when the VL came out , what motor was in that! a turbo RB30 that didnt even have an intercooler was 95 even available then?

fwiw my skyline runs on straight e85 now...like a dream too....

fyi the highway patrol cars (fpv wiith worked engine?) the cops used for pr and community work, fcked up cause an officer filled it up with e10 bhahahah cost them $5k to fix up the engine

That car was tuned to the limit on 98...it was not a "factory spec" car...and he must of been hammering the thing to blow it

Because no-one up there buys it, coz it's shit bro.

If United e85 is good enough for the V8 supercars...

They took over all the old servos up here, the mum and dad places, that have tanks from the 70s... Same with 711 and mobil.

So, while I'm not going to say that the stuff that gets trucked in is crap, I'd prefer not to get my fuel from 40 year old tanks.

There are a couple of newer ones floating around, but I can't even think of the nearest one to me.

[scotty nm35]

New ones are best, but e85 must be stored in special lined custom tanks, not sure about the 98 but I heard they must change them every 10 years anyway.

Scott was just reading a magazine on a modified R35 that runs on E85.

Didnt realise this topic has plenty to discuss about.

I normally use Vortex 98 as we go to woollies to do our groceries so hence i get 4cents off per litre. I do consume about 11.4-12litres per a hundred on 98.

This is very informative (but got lost when everyone starts talking bout compression rates etc... - too technical. i just drive the car coz it makes me look good LOL).

Thanks for the input. I will try BP98 next time as I do feel BP somehow has alittle more ummph!

You are a much better behaved driver than I am. I get 11.2L/100km on the open road and at worst about 18L in town.

As for the BP Ultimate 98, having been a long time fan of Shell V-Power since the Optimax days, I made the switch to BP after everyone I've spoken to in the performance and racing communities. They cited inconsistency in the Shell fuel from one fill-up to the next. I can't say I've witnessed any notable improvements myself but it's a damn good fuel all the same. I'm happy to stick with it.

[INSANITI]

Tony too scared to lose my licence! hahaha. I get enough buzz from commodores and wrx's trying to race me. or the look that i get from girls *i wish i was riding in that him in that car* is sufficient enough <-- wishful thinking.

the car definitely pulls whether on the road or from females. lolz
