oil grade
was in halfords today 10w40 is the standard oil, 5w40 is the upgraded.
5w40 full synth was on offer £27.50 well worth it, but try opie oils web site they do the full kit with filter for various prices.
ps the standard tyres are conti premium contact and they do not last longthey are a soft tread, i've switched to kuhmo, last a lot longer, my dci has the same 16" alloy .
