Until recently Vauxhall had a page on their website that told you what oil they recommended, and now they don't.
This should tell you something, but what, I dunno.
Either they don't know themselves, or have been having so many oil-related catastrophes they have given up.
Or maybe they just want your money, they won't tell you point blank, you have to take it to a garage, they take all your money.
The question is - fully synth 5/40 or fully synth 5/30, which will prove to have worked best after 200,000 or 300,000 miles.
Obviously you need to change it before whatever they recommend. Halving seems to be a good rule of thumb, but dividing by a quarter is probably better.
