Hi all.

I have the mentioned Octavia since May 2016 with 24 000km on the clock.

It's a perfect car, but I observed high lub oil consumption (abt 1.3L/10 000km) with a normal style of driving, without heavy acceleration and etc. I did oil and filter replacement, in dealer's garage, twice (on 11 000km and on 21 000km) and the consumption remains same. I claim this to the dealer, but he refused to do anything, because the oil consumption should be higher than 500ml/1000km (or the amazing 5L/10 000km) to accept the claim.

As an engineer, I know that good engine takes no more than 1gr of oil per 1kg of fuel (weight).

Could you, please, share your opinion and advice.

Best regards.

 

 

 

My experience is that the VAG diesels use oil. I have owned several types over the last 30 years and topping up was never a hardship. Your rate of oil consumption is much less than I got in my 2001 VW Passat 1.9l and less than in my 2009 Skoda Octavia 2l. Neither of the vehicles showed an increased or decreased oil consumption over many miles. My opinion is that your engine falls within the normal operating parameters. My advice is that there is nothing you can do about the consumption and you need to either live with it or get rid of the vehicle, if the oil consumption offends you. The cost of buying 5l of oil to top up over a projected 45000 k is surely not that significant?

My vRS TDI uses about 1L/20,000km. Its been the same for the last 3 years.

As Gregoir said, all engines will consume oïl, some more than others its just part of owning a car.

 

If the garage has checked that there are no signs of oïl leaking from the engine, the turbo or unburnt oïl reaching the exhaust then I guess there's nothing you can do.

I had a similar consumption of an old Peuegot (0.5L/2000km) and the garage also said it was "within normal limts".

 

There are a couple of guys on here who work at Skoda garages who can maybe tell you what VAG class as "normal useage" but I would imagine 1L/10000km would be "normal".

 Yeap for VW guys up to 5L/10000km is "normal" 

I've own two VAG diesels before 110ps AFN and 130ps AWX - with the oil consumption up to 300ml/10000km. And this is the normal one. Same driver, same style, only the oil was 5W40 instead of 5W30.

 

 

 

I'm on my 2nd O3 150PS and have never had to top up between services in over 70k miles, servicing every 10k. In fact, the oil level hardly moves.

I am not gentle with the throttle pedal and mine burns about 2 litres per 30000 km.

(It was the same with my previous Golf mk4 and 5 with 1.9 PD engine.)

During the first period (0-30000 km) with my new Octy I had to top up almost 3 litres but then the oil consumption settled at 2 litres/30000 km (170000 km on the clock now).

As I mentioned I am kind of an agressive driver and I do a lot of highway driving at 140-150 kph. I accelerate with full throttle almost every time.

Think we are talking about diesels rather than a petrol TSI Kodiak (just checked your profile ). My 1.4TSI Octavia does seem to be using some oil though. Luckily my unused  oil for my previous diesel is of the correct spec. 

As I see the Kodiak is on order.

I think andyvee reports oil consumption on his O3 L&K, powered by 2.0 TDI.

I would have done well to have done 70k miles in a Kodiak seeing as the launch date is 6th April 2017!

I know modern engines have come a long, long way - but I recall hearing once that if a new Rolls Royce engine did not use a certain amount of oil in a thousand miles (I think the figure was around 1 pint / 500 Ml) it was considered faulty and was reworked, as it was considered it would not give satisfactory long service. I also can recall 3 bearing crank engines needing a rebuild after only 30 - 50 thousand miles - much shorter if you red-lined at around 8K RPM.
