Hi guys,
I know for the most part there must be a placebo effect, but recently I changed the oil in my 6G75 Mitsubishi Diamante and I genuinely believe it got smoother.
I went from Castrol Edge 5W40 with 6,500 miles on it to Valvoline SynPower 5W40.
The engine is in good condition with no sludge, not even varnish (internals are raw aluminum color).
I have driven the car a few times now and just think to myself it is running smoothly, then remember that I did an oil change.
Is this possible?
The only thing I am thinking is whether different oils stick on the rotating assembly in different amounts which changes the balance and hence NVH?
