For my Alfa Romeo 147 GTA 3.2 I always use your 10w60 oil full synth.
Would it be detrimental to use 15w60 full synth or 10w40 full synth as a top up between oil changes?

Hi Philip
We do not recommend mixing different oils as you will end up with a product of unknown performance and uncertain specification.
