06 1.4 Which grade oil? - GregSwain
I finally replaced the old Almera with something a bit more modern (albeit more basic), but I'm not sure which grade oil to use in it - the owner's manual states 10w30, the Castrol website says 5w30, which seems very thin to me. (I'd want to use fully synth at this viscosity).

Would I be OK putting 10w40 semi-synthetic into this engine? It's the 16v F14D3 engine, closely related to the Vauxhall Ecotec engine which generally takes 10w40 oil.

I know, it's my fault for buying a non-mainstream brand, but any advice would be much appreciated.

Greg.

Vauxhall recommend 5w/30 fully synth (long life) in most of their engines from 2004 onwards (some from 2001/2002 onwards)

Might be worth your while phoning a Chevrolet dealer and ask what they generally use.

Just phoned the local main dealer, and they use Fully Synth 5w40! So it doesn't seem to matter a huge amount, but I'll make sure it's fully synth.

Thanks.
