Advice before changing oil this weekend please
I used to change the oil on my alfa 145 cloverleaf a few years ago - so I still have a half full pack of copper sump plug washers... would 1 of these be fine to use when i change the oil on my 02' 147 2.0 TS ? I've read somewhere that alfa now supply a more modern type of washer with a black seal built in?
1) I will be extremely careful not to thread the plug, but are these washers from the 145 ok to use? (i take it they have the same engine).
Also I have about 4 litres of Mobil 10w 40 semi syynth oil, and an un-opened 2 litre Comma 10w 40 bottle...
2) Can i use up all of my mobil when I change it and use the comma (same grade) to top it up to the desired 4.4 litres? (is it safe to mix brands? i imagine it's fine if the grades are same?)
