Hi, I have a 2002 Avensis 1.8VVTi Auto which has been a great car and I would prefer to keep. Unfortunately, at 72000 miles, it has suddenly started using oil at an incredibly high rate. Pedestrians I have driven past tell me the car stinks of burnt oil and fireworks. The car drives reasonably OK on very light throttle but if I use more, it changes down and makes a lot more noise but doesn't actually accelerate much and then the emissions warning light comes on with a Catalyst reduced efficiency
