Normal oil consumption CTT?

[lewisweller]

What is anyone's oil consumption? I put at least 2 litres of 5w/40 oil in 4,000km before just recently changing oil and filter for 10w/40. 

 

I did find some oil leaking from the block behind the alternator, I put some gasket sealer on there and the leak stopped. 

 

I don't know if my running issues are exacerbating the oil consumption or not as I have yet to really find the smoking gun. 

 

Start up there is no blue smoke, on hard acceleration I don't see any smog behind me, I do get a strong sulphur cat smell when I redline it through the gears up to 160kph.

Just my impression:

Depends on different circumstances. Driving style, temperature etc.

i need about 1 liter per 1000 km :-)

Yes same for me 1 litre per 1000 kms and that is also in the Porsche handbook as normal consumption.

That makes me feel a bit better as I was a little concerned, thought I might be looking at another problem to search for.  

The 2012 Golf R I had before like to burn a bit of oil as well, I think 1 litre in 4000km, my current 2013 Audi 3.0t I never topped up the oil between 15,000km oil service interval which is very good really. But this i guess shows that different engine have very different oil consumption behaviour.

Mine uses about 1 litre per 1500 miles; about a cup of that goes into the intercooler pipe.

Here is the section advising about normal oil consumption on turbo...



You could almost say this beast drinks as much oil as it does gasoline (petrol) to us British. I almost tow a fuel station behind in case I have to go over 15 mph [emoji23]

These are none turbo engines and still high consumption figures. Omg. 

Shifting this topic what are peoples fuel consumption figures like?

I ran the cruise at 138kph and then reset the trip, below is the figures.  

Converted Thats 19.5 mpg UK or 16.2 mpg US. 

Still never seen more than 400 km per tank!

I'm in the UK but also drive it a lot over in Europe on long runs of 800-900 miles. Around home I'm getting around 18.7 mpg (UK) gallons. On the run I might see around 23.8 mpg (UK) from my 2006 CTT. Doesn't CTT= Cayenne Twin Turbo?

Looking at your screen shot remind me of another question, does anyone know how to change the KM or MPH display on the PCM maps display? My car is originally from Germany so LHD and in KMs. I changed the dashboard display when in UK to MPH via the main dash computer but it didn't change the PCM navigation or trip computer figures.

CTT yes cayenne twin turbo, mines also a 06 with the E81 power kit giving 500bhp from factory. 

Your figures of 23.8 mpg UK is very good, most people get less than 20 mpg UK and 13mpg us. 

I bet having the AC off and the high or medium cruising speeds heavily affect what you can stretch out of a tank full on long runs in this thirsty Be-ach. 

Changing the pcm units I will check mine to see if any option to change, it's probably set in the maps CD drive settings maybe not able to change with UK map CD.

I think we have quite similar engines Lewis and we get similar mileage – combined city/highway is usually 14.5 l/100km range, best on the highway is around 11.0, drive it hard and it can be as bad as you want it to be! Also, I have the PCM 2.0, but it also has the option to change units.

[angusc]

Zakowsky,

Where do you have the option to change units on your PCM?
