I have a 2004 Toyota Avensis HATCHBACK - 1.8 VVT-i T3-X 5dr and it has been in my family since showroom.
Generally can't fault the car one bit. Nice smooth comfortable cruiser on the motorway, has a ton of decent features for a 15 year old car. I found the build quality to be great and repairs minimal and inexpensive.
Over the last couple years things have started to change as the mileage has increased. Currently it is on about 90k, with about 35k done in the last 2 years. During this time I've noticed a gradual increase in oil consumption. Initially it started off using all the oil in about 2-3 months, then slowly moved to 6 weeks and this year has jumped to every four weeks and now every 2 weeks. The car only ever indicated low oil when it was pretty much empty, and since last year I've made sure to check the dipstick every week.
The car has been to my local mechanic, he's been my go to guy and has never let me down on repairs. I've always told him about the oil consumption, He's checked for oil leaks and did not find anything, I took it to him again today because I couldn't believe how much it was burning and again no signs of any leak. He recommended I replace the car 😥. It has been well looked after and passes MOTs first time. Decent fuel consumption, no lights on dash, all electrics work fine, and no exhaust smoke either. Headlights are dim but I've come to understand from this forum that it is normal for my model.
I'm constantly using it for long drives across the UK and it mostly seems fine other than the oil consumption. I've come across a thread that mentions one avensis engine using a lot of oil but not sure if that engine is the one in my car.
To summarise above and a couple other points, below are 3 problems I'm facing
Heavy oil consumption, every 2 weeks I'm having to fill it up again
Car goes in to 3rd-4th gear without using the clutch and carries on driving as normal
Chain rattle on left hand side of the car under heavy acceleration.
That's pretty much everything about the car. What do you think and what would you recommend I do? If I keep driving it, will there be bigger problems relating to the oil consumption?
