I've got my first car, and have had it now for about 4 months. It passed an MOT 2.5/3 weeks ago, so I was happy with that, and thought I could carry on happy as Larry using it with no worries.
However, recently (maybe for the last week) I have started hearing a difference in the engine sound. This only occurs when in 5th gear, and when driving 60-70mph.
Usually it's been a pretty quiet engine, but lately it's been sounding really loud and like it needs to be moved up a gear as it's working too hard, but there can't be anything wrong, since it only passed the MOT 3 weeks ago, right?
Is it just a simple of case of needing the oil changed? I've already checked it, and it was above the minimum line, but is it worth changing it anyway?
The car is a 2004 Nissan Almera Pulse (53 plate).
The noise kind of sounds like there are too many revs for the gear that the car is in (5th gear, rev count 2500-3000), but maybe a little less aggressive.
The noise certainly sounds like it's coming from the engine bay.
The noise is intermittent, and only ever occurs when travelling between 60-70mph.
The vehicle does not behave any differently since the noise first occurred
