Oil Consumption 997.1

[slahti]

Is it usual to have to top off oil in my 997.1 S Manual '06 with 40k miles?

I seem to have to add a quart every month or so there are NO OIL leaks while sitting. I park in the same spot at work,

and nothing in my garage. Just wondering if this is usual for a Porsche of that year.

:thumbup:

Thanks in Advance

Not sure if this helps, but the owner's manual seems to indicate some normal consumption is expected and varies based on conditions (including your driving style and oil used).

I realize your car isn't brand new, but here is some verbiage from the manual that would appear that you are OK.

Engine oil and fuel consumption During the break-in period oil and fuel consumption may be higher than normal.

As always, the rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate and road conditions, as well as the amount of dilution and

oxidation of the lubricant. Make a habit of checking engine oil with every refueling, add if necessary.

Engine oil consumption up to 1.5 liters/1000 km

(1.6 quarts/622 miles)

Engine oil consumption

It is normal for your engine to consume oil. The

rate of oil consumption depends on the quality

and viscosity of oil, the speed at which the engine

is operated, the climate, road conditions as well

as the amount of dilution and oxidation of the

lubricant.

If the vehicle is used for repeated short trips, and

consumes a normal amount of oil, the engine oil

measurement may not show any drop in the oil

level at all, even after 600 miles (1,000 km) or

more. This is because the oil is gradually becoming

diluted with fuel or moisture, making it appear

that the oil level has not changed. The diluting

ingredients evaporate out when the vehicle is

driven at high speeds, as on an expressway,

making it then appear that oil is excessively

consumed after driving at high speeds.

If the conditions you drive your vehicle in are dusty,

humid, or hot, the frequency of the oil change

intervals should be greater.

If the vehicle is driven at a high rate of speed,

climatic conditions are warm, and the load is

high, the oil should be checked more frequently,

as driving conditions will determine the rate of oil

consumption.

It would seem that you are fine. Depending on conditions of inner parts, it is possible that some wear could be causing increased consumption, but you seem to be in normal range here based on the

limited information.

Hope that helps.

Great info and :thankyou:
