For the past few weeks my car seems a bit slower and requires me to accelerate kind of harder. When I'm driving the "real time" MPG option shows that I'm doing about 9mpg when in second or third gear while accelerating very softly. Even while on cruise control it goes down to about 35mpg while doing 60mph on a flat level surface when normally I get about 49-55mpg (real time MPG)
Tyres have been checked and pumped up correctly.
Air filter has been changed about 4000 miles ago.
Fuel filter hasn't been changed since I've had the car (had the car for over 2 and a half years)
Oil is changed every 6-8 thousand miles (GM Dexos Oil) - Due for an oil change this weekend.
Coolant temperature is about 81-83 degrees after a 30 mile drive @ 65mph
haven't checked my crank case breather so not sure if its a loo-roll type that might be getting blocked?
Any ideas?
