Car Burning Oil - Manufactuer Won't Fix

HI, I would welcome any suggestions on how to deal with this issue:

*My car is under warranty but it runs out in a few months *Car has progressively burned more oil over the past year (Started at around 1 litre every 4000 miles, now it's at 1 litre every 1700 miles) *I have provided a detailed log showing how much this is burning to local dealer and customer service where I have raised a formal complaint *Manufacturer has claimed according to their factory spec that on average their this cars can burn up to 1 litre every 800 miles (dealer then said for this car it's 1200 miles) and that's 'within permissible limits'

I have been raising this issue over the past year and feel that the most recent suggestion (do another oil consumption test) is a delaying tactic and that by the time this is done, warranty replacement of an engine if this is required won't be covered. They have offered to do an in depth check now, but if they find nothing wrong I will be stuck with the bill.

I appreciate any suggestions you have to help to resolve this issue including what is available to me as a consumer in order to get the manufacturer to cover what I think is fair on their part

Many thanks Fred

The make, model, engine type and mileage might be useful if you want feedback as to whether the consumption is excessive.

You're massively over-reacting over nothing.

Without knowing make etc it is hard to say. My puggy 206 hasn't drunk a drop of oil in 20000 miles.

None of the Zetec-engined Fords I've owned in the last 15 years have ever needed top-ups between changes, despite mileages of up to 100K. OTOH, the OP's oil usage may be normal for that model.

Same here for my Saab 9000 in 161000 miles.

Mazda 6's drink oil.

PCV The PCV (Positive Crankcase Ventilation) Valve is a check valve that allows excess exhaust fumes in the crank case to re-enter the intake manifold and be re-combusted for emissions sake.

Problem: If the valve breaks (its basically plastic), one of two things can happen,

1: The valve gets stuck close. Pressure builds up in the crankcase, eventually finding an outlet. This usually results in oil spraying back up into the intake tract, or blowing the dipstick out of its holder.

2: The valve gets stuck open. When vaccuum is applied (application of throttle), the intake air sucks the oil out of the crankcase using the pcv hose as a large straw.

My 118,000 04 plate Mondeo uses none. My 23 year old Capri with 80k on uses none. 1 litre between services would be reasonable.

Seems like that would be noticeable?

That sounds like a litre per mile, not 1700 miles.

Seriously though, a lot of modern engines (I've heard) get through oil like there's no tomorrow.

I had a Supra once that drank a litre every 300 miles or so, but I could see where that was going in the blue clouds behind me...

So you're saying you have never changed the oil (or had it changed) in your Saab in 161,000 miles?

Yes, my Astra 1.6 seems to consume a lot, and I have to top it up every 2K miles or so. I change the oil and filter every 6 months anyway.

No we are saying that the cars haven't DRUNK any oil which is a totally different thing.

How would you know that if it has been refilled every 10k(?) miles?

[...]

Presumably because the level has stayed the same on the dipstick during that time?

Derrrrrrrrrrr. The oil level hasn't gone down at all between changes.

How do you measure a drop of oil with a dipstick?
