Just a thought
I would only run a genuine oil filter apart from recommended filters from traders/tuners who are in the know.
Could cheap filters also be a contributing factor.
Thinking about internal filteration breakup causing oil flow issues.
It was probably more mate but as they go for 10% + 2mph to make sure they win if you go to court think yourself lucky.
Most people have 3 points nowadays at least.
I`ve been clean for a few years but it just makes me think its a case of when not if.
