Its not designed for older engines, its designed for more modern engines on the 2 year service scheme, mostly because you've done an oil change by then with topping it up all the time!
Yes non abs and as it's technically an STDI a crap suspension too, the Lupo Sport TDI is a much better set up. I've made the stupid mistake of upping the engine output without first doing suspension and brakes, I knew better 25 years ago
My airbag light was on and it turned out to be the clip on the clock spring that clips into the airbag. Basically the metal contacts inside it had been pushed in and weren't connecting. Manoeuvred them back into position, cleared the light and it's been fine ever since. Another thing to possibly consider/check.
This would bring me upto recently and the most recent photowhoring of the car, have a few more plans in mind so will be on here a bit more for some advice.
The research guys I know at the BP/Castrol science centre told me that oil only matters when it gets old. Really old. They explained that if you change it at under 5k miles and with regular driving (not really short trips), the additives have only just begun to start doing their thing. Something to do the 4 ball wear test (worth a google). HD oil is different. The lower number viscosity rating number only really matters when caning it with an ice cold engine. Like 0W40 or 5W40...
