Yes they do, my dealership still offers the semi synthetic 10W40 or fully synthetic 5W30

I used Mobil 1 0W-40 on my 1.8 Astra - expensive but still running better than new at 98,000.

Don't get hung up on part-synthetic (it's not "semi" it's anywhere from 1% to 99%) versus fully-synthetic, that's for the oil chemists.

For a 2002, Vauxhall recommends 10W-40 or 5W-30, ACEA-A3/B3. The API rating should be SL or SM as SJ is now obselete.

5W-40, 0W-40 and 0W-30 can also be used - with the benefit of reduced start-up wear which is just when most wear occurs.

Search for oilman's threads if you want much more detail.

The 10w/40 recommendation is for the Vec-B
The 5w/30 recommendation is for the Vec-C

if you read it meant to say they do not supply mineral oil anymore.

Couldn't find an edit button but have corrected my post here.

That's how I interpreted it as.
