Thanks George. Very Informative. Minimum for K-jet would be 95, but recommended 98, but most I'm sure.

I wonder if they have, or ever will have a 95 based e10??

In theory, (or experience) does anyone know about any problems with e10 and K-jet, besides the low octane rating?

I think the Shell Vpower racing is 98 and 5% from memory, Not many places sell it though.

there are a couple of places here in sydney that sell v-power racing, and apparently the ocatane rating is 100... who would know...

Another exerpt from the Shell Aust website:-

Shell Australia would like to inform our customers that from July 21 we will be gradually phasing out Shell V-Power RACING fuel from 46 Coles Express sites in QLD, NSW, ACT and VIC. Availability of Shell V-Power will not be impacted by this change.

So I suppose then my only future option for a high octane fuel would be to include additives ?

NO grilling on the Ethanol fellas you are right the ethanol actually raises the octane level by 3. Just been at a BP fuel seminar through the IAME and was imformative. Still having said that i would be using 98 ++ without doubt.

Higher than 98? Shouldn't need it, 98 RON will be fine, a higher RON rating than the engine requires is a bit of a waste.

According to the owners manual for my '76, it needs fuel with a minimum octane rating of 91, which what standard unleaded apparently is so it's technically ok. However, if the actual octane is lower than it should be premium unleaded would be the go.

I occasionally used premium on my old beetle and noticed a difference (but that was back in the day of lower fuel costs, more disposable income). I'll try it on the Golf next time round (just put in half a tank of regular today ) and see how it goes.

Does higher octane give better economy? I don't get great economy as I do a lot of stop/start CBD driving.

If find that with my mk 1, you can feel a subtle difference between premium and reg. Not much, but you might find it runs a bit smoother. I generally, fill up one tank reg, then premium the week after. (not always full tanks either) Donno about econ though. I'm doing 11's (last tank) and that's also generally city/flogggin it.

Although, K-jet is something else all together, and is very specific about octane ratings, unlike our old wee carby's...

Dont run it on 91 octane. Are you crazy?
98 thats it. It costs a bit more, but you go further so it works out the same.
Australia runs on 3rd world petrol, thats why its so cheap. Its actually a couple of octane points lower than european equivilants. Thus aussie 98 is probably the same as German 95 and the 91 you are putting in is really 88.
Lots of euro cars are detuned for aussie petrol when they are shipped here.
Put in the good stuff and I reckon you will notice a difference and will never go back.

Who told you that one? RON is RON, in the US they have their different standard that would make 91RON their 88.

Run 95 or 98 in it and see what happens, the best 98 is BP Ultimate, but the Mobil stuff is a bit cheaper and doesn't have the extra cleaning chemical in it that the BP stuff does even though they are from the same refinery.

Yup the V-Racing was 100 octane. I put some in a VR6 and could feel the difference.

I would use E10 over standard unleaded any day.
Tried it in the Audi when the 98 pump was "out" and it seemed to like it.

The cabrio would have had a sticker on it somewhere saying minimum octane 95-98

I put a bottle of Wynns octane booster in yesterday as I already had a full tank and the pinking has stopped...You can hear a slight pink under hard load but it goes very quickly so it would seem it is set up right and just needs a higher octane fuel.

Thanks Guys, appreciated, happy as now

Thats good mate and by the way most engines or in fact all do ping but its the audible ones you should be concerned about. Thats why the introduction of knock sensors and the likes especially now with the new now leaner burning engines. Not so much your though but all i can say is with Kjet treat it with respect and change your fuel filter regularly etc as they absolutley hate dirt or water. Make sure your fuel filler neck is nice and clean so when washing inspect it. The older ones used to get like T bags and let in road crap and water ,thus killing the system. Spent MANY hours with Kjet cleaning adjusting , replacing and setting up due to this. Still sounds like you know whats going on though mate i just had to throw this in.

No Mate, appreciate all comments, suggestions. I will keep my eyes out for the above. I could do with a new fuel filter to be honest..

Thanks buddy !

Tried (accidently) the V-Racing and found the fuel economy and performance to be worse than when using V-Power.

Just a couple of observations from the thread (PS not a mechanic) :
- E10 can cause some nasty issues is older cars, particularly around seals and the like.
-The old metho trick does work to help disperse water, have done it many times in my old golf.
- Agree that a premium fuel is better for the later Mk1 cabrios as they run cleaner and more economically (best so far is 600km on 48 litres on M1), probably because the engines in most of these are GTI engines weighed down by lots of extra weight.
- A WORD OF WARNING: If you have an older car and you start to use Premium, make sure you change the fuel filter sooner rather than later as the Premium has a habit of lossening krud in the tank that has accumulated there for a few years.
