Ok, so I let my mum drive mi car today as mine was at the front and she could'nt be bothered to get hers out. She comes back and tells me the oil was low and she had bought some and put it in
I thought, oh no.
Now she has gone and got some:
Total Quartz 7000 semi synthetic 10w40. Super Multigrade engine oil.
It says Superior car for your performance engine.
Question is: Is it ok for my Astra GTE 16v (20XE engine) or do I have to change it pronto as it's no good for the engine. And if so what oil do I replace it with.
