I run my 5 pot coupe on high octane unleaded with no real problems. admittedly I only do limited mileage but is seems ok. If in doubt I would maybe use an additive plus high octane.

I'm sure one of our more knowledgable members may be able to help more.

It'll run just fine on 95RON, maybe a bit more spritely with 98RON...

And no knowledge on the bleed screw, unless there's something around the heater matrix to vent out airpockets?

I've used 95ron normal pump unleaded in my Sport since I've had it and no problems at all and that's done 8000 mile since I've had it.

All audis since 1974 have been capable of running on unleaded iirc.

Could be about right cos all VW's since 1972 have been able to run on unleaded.

Put V Power in it and get better performance, and fuel economy, which offsets the extra cost.

how much mpg do you get in your 100?

I run mine on 97, seems to go a bit better and seems happy. 95 seems fine as well, 99 from Tesco is a no no, my car tends to cough and splutter!

On the fuel filler cap it says 98, but then 97 is its replacement. Surely if it's set up for 98 originally then now its been retarded to run 95 unleaded at some point? Still a mystery as to whether mine's been adjusted to run 95...
