Quick question....does the S2000 need Super unleaded (both old and 2002 model)

What sort of MPG do you get ?

 

I believe Honda states that the "S" requires 91 octane gasoline. However, the timing/ignition system will advance/retard the spark to take advantage of higher octane fuels. I typically run Shell Premium 93 octane unleaded fuel.

Remember, in the States we quote average octane values (average of Motor Octane & Research Octane). Without getting into the differences, for conventional refined and blended gasolines the Research number

 

SUL is recomended for the car but it will run on normal 95 Ron premium. I find it runs smoother on SUL (97 Ron) and in particular Optimax (~99 Ron).

 

I normally fill up with 97ron or optimax, normally costs me about

 

If you look inside of your filler door it should tell you to use min 98RON fuel (mine does anyway)

Don't want to be too picky here, but firstly most UK cars have F20C-2 engines which Honda recommend 98 octane. Lower octane for short term emergancy use only.

Sorry for my dated information , the EU did indeed phase out leaded gasoline in 2000. Since my buddies with Caltex in Hammersmith were made redundant, I have lost track. We worked together to build a gasoline blending plant in 1995-6, and I was told it was still operating. They must have closed at least one valve.

It is still surprising that the EU took so long. I wonder what my father (lives near Oxford Circus) is doing to fuel his old V-12 Daimler.

I am lucky to get 20-22mpg from my JDM model with 100octane - must be the way I drive, but fortunately I'm managing to get the premium fuel for 50p a litre so it's not so bad I guess.
