Well Joe, that's a bit high.

I never went over 4000rpm and rarely over 3750 even when shifting.
Always cruising at 55/60, never never even at 65.

Shifting at 3500 at the most in normal driving condition, many don't
believe my fuel consumption but i mostly cruise at 55/60mph.

I don't like the noise of this engine over 3500, it doesn't sound right.
