(My battery is fine and the fuel injection system has been cleaned out) so Can using synthetic oil make the pathfinder sound like its is struggling when it is starting up?

I heard that the "thinner" nature of synthetic can magnify any pre-existing leakage problems.

Maybe it is struggling because it all leaked out? lol
