Hi all. Just wondering if anyone could tell me what size is the allan key to get the sump bolt out and can you buy them seprate? Thanxs:

Just found out its 12mm

Sorry this may sound thick but what type of oil make or grade this is my first Fiat and I want to get it right please:worship:

a cinquecento/seicento takes 10w40 semi synthetic.

any brand/make will be fine.
