My oil gauge is currently showing o o o o _ _ so I'm looking to top it up. Few questions:
1. Halfords stock is s**t and I really want it sorted this weekend, is Mobil 1 0W-40W ok for top up? The only 5W-40W is there own brand which I don't want to use.
2. I haven't got a clue what the factory put in, is it ok to mix semi and fully synthetic?
