Originally my 350Z service intervals were relatively easy to understand: P1, P2, P1, P3 then repeat.
Then the Ps disappeared and a Gs arrived but I've never been sure whether that made it: G1, G2, G1, G3 and repeat?
However we now seem to have "Minor" and "Major". I'm assuming that means the cycle is: Minor, Minor, Minor, Major then repeat? This would make sense because we quite quickly discovered that the only difference between a P1 and a P2 was price!
But does anybody know if my assumptions are true?
