    Use 98 if you don't wish to hear pinking, pinging, spark knock and many other terms which describe that metallic popping sound from under the bonnet.

    I use 98 in my short stroke engine. I put 95 in recently (I was in the country) and had to thrash the thing to get some go.

    After recent debate, I needed fuel in UFO (the car not me) this week and I put 98. I drove to work this morning (35km, mostly freeway) and I forgot how well the car goes on 98. No more 95 or whatever for UFO.

    98 always. Hard starting on 95 (as well as pinking), 98 no problems.

    Hobart, Tasmanian state capital, no 98 north of the city.
    Once you're over the Flannie Border it's 95 only.

    A trip to the airport to pick up visitors is always welcome for the Safari, they sell 98 on the way into the airport.
    The prices you can probably guess.

    June gets 98 unless I can't get it, such as on the trip to WA at Easter. Octane booster was much appreciated!

    At least you guys have 95, we are stuck with 93.... So our car's performance will never be optimal!! You guys are lucky!

    I only ever 98. If I think its not going to be available on a trip I make sure I fill when I can with 98.

    I reckon if I keep buying only 98, its not as likely to be removed from the forecourt bowsers.

    Hello, European 95 has up to 10% ethanol, which seems to be fatal to old rubber and plastic fuel lines etc. There is no ethanol in 98 and mine runs better

    Then why did you ask?

    The DS has an alloy head with hardened steel valve seat inserts. Lead replacement additives are absolutely essential for older iron heads, like say an MGB, to counter valve seat recession but I believe the Citroen engine is fine without.

    Next time you are talking to your "DS mechanic" please ask why, and tell us the reason.

    My own understanding is that the alloy head means no need for additive.

    Ditto.

    Only because Ive not used a lead replacement at all in my D's. The engines haven't died or shown signs of valve problems.
    Happy to learn.

    Interesting.... If your DS mechanic is still the same one, then I am sure he has seen many the insides of a DS engine.

    Fair enough. I take that on board Michael. I only mentioned it as this was a petrol thread. So many people I know with Dees don't use lead but my guy said you should run the lead replacement through the petrol every third fill or so. He did tell me the reason but I was thinking about ice-cream or something at the time (groan). You know who it is. Do ask him why he said a D owner should add lead. Said it was important. Dunno.

    Whilst the cylinder head is made of alloy, it is the direct relation between the material used for the valve and valve seat which is of import.

    The D cylinder head is fitted with hardened valve seats, which prevent valve recession.

    There is no need to use any additive. That's the simple answer.

    michaelr; you are correct.
    Older cast iron cylinder heads were often fitted with a softer valve seat.

    As I said, please ask him the reason next time you see him, and tell us.

    I think it is unreasonable for you to expect us to help you if you don't want to help us (or help yourself, for that matter). This is, after all, a community.

    Yeah I'll ask him next time I take the car in. Didn't realise I was letting down the entire citroen community by simply canvassing other d owners about their thoughts on petrol. Will give myself a stern dressing down Rodger.

    Have not put in my '2 cents' worth on this as this subject is almost as sensitive as which hydraulic fluid to use in the cars . That said I will just add that D engines with their anemic 8.5 to 1 compression ratio don't need high test gas. If one is getting pre-detonation the problem is going to be ignition advance, a slightly lean fuel mixture, to narrow an electrode gap or a combination of factors. Higher octane rated fuel blends do not provide any more 'power' than lower blends - the specific heat content of both is the same per given quantity - be it a liter/quart. In a typical station there are two supply tanks. One has the lower octane fuel, the other the higher. If a middle grade is desire (or offered) the delivery pump just mixes the two internally prior to it going into your tank.

    The engine in my 72 is running with a 9.2:1 compression. It runs quite happily on California's 87 octane. Now keep in mind that there are two distinctly different methods of rating gas octane - MON and RON (Motor Octane Number and Research Octane Number). The same sample of fuel will give readings about 8-10 units apart depending on the method used. IOW gas labeled in Canada as 82 octane will be the same as gas rated 90-92 octane in Oz. Most all stations in the US now use what is known as the 'AKI' (Anti Knock Index) number with is nothing more than RON+MON/2. So the 87 rated stuff I use is the equivalent to 92 down under. And 87 is the lowest grade available, at least in California. Your '87' would be about equivalent to an '82' grade if it were available here. And a grade that low could indeed cause problems in a typical D engine with a bunch of miles on it. The basic problem being a worn camshaft profile which makes getting any decent low engine performance + avoiding pre-detonation a real challenge. Modern engines with electronic controls, variable valve timing and 'knock' sensors can deal with this.
