I changed the oil today and it fits. M12x1.75 is accurate.
I have purchased Fumoto in the past, but I must say the quality of the Deefill is clearly superior.
BTW- the stock plug is either not magnetic or extremely weak.
The black convertible with the premium wheels looks awesome! I don’t think you can go wrong with either color.
Black is just such an SOB to keep clean.
I am lucky enough to have driven both. I have a GT Premium and my brother a DH. His does not have the handling package. The motors feel identical in terms of acceleration, torque curve, 40-60, 60-80 pulls etc.
