5w30 is too thin mate, it will tap like fook!
I used Castrol 15/40 in my last one and was alot smoother and quieter. Depends how your engine is I guess, was alot smoother on 15/40 than it was 10/40 anyways

I concurr... fully synthetics aint what the engine was designed for. The gm 10w-40 stuff will do it best. I say stock up from autovaux at pv for about a 10er a can

Just have to wait 11 months haha.
Try "vauxpartsworld" that's where I get my gm oil. I collect so it's about £11 for 5 litres. However I'm pretty sure they have free delivery too
