I have trawelled using search thorugh all the posts about which grade petrol to use. I am picking up an MY98 AUTO sportwagon tomorrow and I know that it is going to have an empty tank. When I get to the petrol station what do I need to put in it?

NUL or SUL?

Which gives best MPG, and which will give the most power/smoothness?

Will optimax have any effect? You have mentioned that it contains cleaning aditives, whould that benifit the engine?

I am only intrested in the relavance to a sport, not a turbo, and it is a uk car not an import.

Let me know?

I ran my sport on 95ron for 2 1/2 years. went fine for me. I didnt notice any diference with SUL.

I only run mine with Optimax

Used to use regular 95 RON, but the car definately pulls much smoother on Optimax - performance all in the head

mpg much of a muchness - more down to your right foot that the grade of petrol...

Run my old my 98 on 95 ron had no probs now have my00 and have only used Optimax mainly for its cleaning, not noticed any diff' in performance or mpg

We used to have a Sport. Only used Optimax or SUL. Couldn't see any difference in mpg. Seemed to run smooth etc but only really noticed it when putting normal 95 unleaded in once; when pulling up a hill (not labouring) we had a load of pinking so the ECU must make alterations accordingly.

Ran mine on 95 most of the time, occasionally treating it to a tank or two of Optimax. Didn't notice any difference. 95 ron will be fine.

i ran my sport on 95 with no problem. There was a noticeable increase in smoothness with 97, which I treated it to once in a while (every 3rd or 4th tank) and I did get another 20 or so miles out before the low fuel light came on, so worth the extra.

Also, higher octane is always better for your engine in the long run.

I now have the above mentioned sport, and tried SUL and Optimax for a while. I have gone back to 95 Ron, and haven't noticed a difference

95 ron got me home, so I think I will stick with that, and it only seamed to take £35 to fill it up? Was expecting to be a lot more?

Avi

£35 is very empty

naturbo2000

It's only a 45 Ltr tank (10 Gallons)

so 35 quid of 95 RON == *very* empty

Nexuas

Think it was 81 pence a litre? (Warick services)

So 35 divided by 0.81 = 43 litres

so I had 2 litres to spare?

When I got in and started it the petrol needle did not move at all.

naturbo2000

the needle stays set even when the ignition turned off in scoobs.

you'll notice it's on full (or whatever) when you next get in the car.

If you've got the revised interior, you ought to also have a low petrol warning light, but I'm not sure they put this on sports.

Pre-98, we all have to guess - arrow pointing through the E == keep fingers crossed you can stop somewhere!

Avi

Mine has the Petrol Warning Light

Nexuas

Got the warning light, that came on during the test drive, when I hit the kick down button on the floor and the car accelerated.

Isn't it a 50ltr tank in the classic?
It certainly is in the '01/'02 models.

naturbo2000

no...
