I apologise in advance for such petty questions but I've never done this stuff before.
I have a Golf Mk4 2.0 GTI and the oil light came on about 5 miles ago on my way home. Tomorrow morning I'll check the dipstick but assuming I need to top up, does it matter about mixing new stuff with whatever is in there at the moment?
I've been told that I need to buy semi-synthetic but how much will I need?
How do I know how much I'm putting in? Do I put some in and check the dipstick every so often?
Thanks for any advice
