Hi, i have used amsoil signature 5w30 in my 2010 mk8 1.4 ivtec civic for the last 3 oil changes . I now realise that maybe i should have used the european Amsoil..Amsoil signature appears to have an HTHS of only 3.1 where as the european oil is 3.5 which may mean more wear protection.. my honda doesn't have a turbo (though of course it has a catalytic converter)
... so I'm hoping the higher saps in the Signature oil has not caused any problems . Should I switch to the european Amsoil
