Oil usage?

[RayVonn]

Just wondered how much oil people are using in their S6's?

Since I've been doing a hefty mileage in the Tuscan, I've noticed it's doing about 1/1.5 litres to every 1000 miles - which I believe is about average. Just wondered what others were getting?

well i was expecting that kind of consumption in my cerb when i bought it.
only put about one litre in during 6000 miles,when the oil change was due.
i take it i've got a pretty good one

To date I have never had to add oil between services on my T350. However many people expect to add a litre per 1000 miles. My Cerbera was the same, did not use oil between services. The Chim however used about a litre every 6000 miles. I use Castrol RS 15W 60, (I think that is the spec) in the T350.

A big factor in the use of engine oil is the nature of the engine use.

With my original Speed 6 (2002) engine I had to top the oil up every journey, and I use it regularly doing about 60-100 miles per journey.
Since my engine upgrade to 4.0L RR in May I have never had to top the oil up and I'm using it the same as before the upgrade. I also notice that prior to the upgrade the oil got darker quiet quickly, but since the upgrade the oil is still quiet clear. I think this is the sign of a good engine rebuild.

Agree with this. I use 15w/50 mobil 1 and engine uses no more than 500mls every 6k miles

The other big factor is the viscosity of the oil that is being used.

ChrissyG confirms that the oil in his/her car is 15w50 and that car uses little oil.

Originally people were using thin oil 0-40 5w50 and the like and found that the engines were using a lot because it is so thin.

Unless you are using this very thin oil and unless your car is leaking, then it must be using all that oil by burning it.

If it burning that amount of oil then it is burning oil like an old banger and there is something seriously wrong with it.

If you are using very thin oil then try something like 15w50 and see if the burning stops.

Right again,noticed a large increase in oil consumption when on holiday driving around europe at mostly 3figure speeds with temp's in the 30s

Well I suppose I should've mentioned that the 1,000 miles that I did last week was actually the only 1,000 miles that I've done in the car as I've only just taken over ownership. Prior to me getting the car, it had only done about 1,300 miles - so even now its still only done 2,300 miles approx. Maybe this affects consumption?

Plus, most of the mileage was on motorways at highish speeds. And the oil in the car is 5W40, so maybe that makes a difference too.

The engine is a 4.0 Red Rose too.

Ian who did the machining work on your engine upgrade?

I supsect thats a function of the old engine being shagged as much as the new one being frugal. Dark oil is usually caused by crankcase pressurisation (old worn motor)

Paul, no idea who did the machining. Have a chat with Richard at Dulfords as he did the engine upgrade. He definately sent the engine away somewhere to be balanced, but where I don't know.

Is it all the latest engines (less than 3 year old) that use less oil... Seems to be theme in the threads I've read through.

I've only done about 2k miles in mine and it hasn't used any. Dec 2005 engine.

cheers

Biggest cause of high oil consumption on the S6 is worn valve guides. This is more prevelant on the early engines as they used bronze alloy guides. The later engines use a harder material.

.. apparently same material but phosphor coated to extend life, a common improvement.

My Mk1 used about a litre per 1000 miles. My Mk2 uses 1 litre per 6000 miles. All using Mobil 1 0W40 btw.
