What petrol you use for your Euro?

[aaronng]

its all in ur head...
but with australias disgusting fuel i'd go one level up from what the manufacturer recommends, if they say 95 then use 98, all the leading petrol companies have basically same fuel, bp, shell, caltex etc, doesnt really matter which one u get, just dont fill up at those dirty independant petrol stations...

The 91 and 95's are the same or similar. The 98's are different.

some handy info~ http://www.fuelwatch.wa.gov.au/info/dsp_fuel_types.cfm
Apparently WA has the cleanest fuel

98 RON

98 RON is a high-octane unleaded fuel that maximizes engine power and performance, as well as producing less pollution.

BP is currently the only reseller of 98 RON petrol in WA and markets the product under the BP Ultimate brand name.

98 RON is promoted as providing excellent fuel economy, has a sulphur content which is 10 times lower than the national standard for unleaded fuels, and has low levels of benzene, sulphur and lower aromatics.

98 RON is used by some imported and high performance vehicles

Premium Unleaded Petrol (PULP)

PULP is a special blend of petrol designed to bring high octane, and hence high engine power, as well as knock- free performance to unleaded cars with a high-octane requirement.

A knocking noise can occur in an engine when there is a mismatch between the fuel characteristics and the engine's design, particularly its compression ratio, resulting in pre-ignition (also known as 'pinging').

Selecting fuel with the correct RON for your engine will prevent the knocking fuel effect caused when the fuel combusts in the compression chamber too early.

Many imported cars, and particularly those with turbochargers, are manufactured to run on premium unleaded petrol.

PULP has a Research Octane Number (RON) of 95.

RON is a measure of a fuel's compression performance and the RON rating translates into the amount of engine power. RON requirements vary according to engine type.

Just following up.

I've gone down from 98 to 95, and to tell you the truth, my butt dyno can't feel any difference, and my fuel consumption actually improves.

Can't notice diff between 95 and 98 makes sense but higher consumption on 98!!!

I use 100 sometimes

lol

anyone notice that with 95, the engine is rougher? not as smooth as with 98?

i've also said this before and i will say it now, i dont know why the fark they say 98 has gives u better fuel economy than 95 or 91, i refuse to believe it since i've seen on my civic when i ALWAYS got atleast 50kms more out of 91 than 95 or 98.
i also get the same thing on my accord which is a SOHC Vtec, driving conditions are always constant, and i get more kms with 91 than 95 or 98, so this is 2 cars i seen that has totally disapproved the idea that higher octane fuel works out cheaper in the end cause for me it means paying more for each litre and getting less kms...

I get 9.1L/100km consistently with BP ultimate and I have been running the car on BP ultimate from Day 1 (short of the rubbish from the dealer when it was delivered). That's better than most have achieved using 95 RON in an automatic. I do a mix of highway/peak hour driving too.

10000km in 6 months so my engine is relatively run in.

98 RON with some fur additive for lean combustion
