Welcome to our little club and congrats on a fine choice of car!

Here's a quote from my earlier post on running unleaded:

"Volkswagen officially state all Mk1 Golfs can run on unleaded petrol with a octane rating of 95 RON or higher.

If your Mk1 Golf is a GTi, then using 95 RON unleaded will require the ignition timing to be adjusted as follows:

1.6 (EG) engine 6 deg +/- 1 deg ATDC
1.8 (DX) engine 0 deg +/- 1 deg BTDC

If you modify the ignition timing, you must mark the vehicle with a sticker PN 000 010 007F on the petrol cap/filler.

Using 98 RON unleaded will not require any timing adjustment.

If your Mk1 Golf is not a GTi, you can use 95 RON unleaded wihout any ignition timing adjustment. "
