Thanks Mike,
This makes me feel a lot happier. I'll use Shell Optimax, as that's full of lots of good cleaners etc. and is apparently good for engines.
There was no manual with the car or any other service history, mind you i only paid £300.00 for the car. having said that i can't believe what a fantastic bargain it was, i've cleaned it up and mechanically it all seems very sound, i can now turn my meagre talents to sorting out the chrome trim and the very few rust spots.
it's a hilarious car to drive, i mean it, it hates any driving input from me preferring to just roll along at it's own pace. i simply sit back and relax with a big grin on my face.
