I have a 94 GtSwith 53K and it seems to need a quart of oil almost every other take of gas. No leaks noted and engine compartment clean. Is this normal?
Thanks

 

Hi,
what oil ( brand, type, viscosity ) do you use and how many MILES per quart? How do you really operate/drive the car - where and how?

These are important "know" issues in order to provide a meaningful answer

Regards

 

There is a GTS up here in the Pac NW that had the same issue. Apparently the oil rings on one or more pistons were "siezed" allowing the oil to pass. Was thought to have occured when it overheated at one point in its life..

Hope that isn't it....

Good luck finding out what it is..

castro 20w-50 usually. car is driven in city but not too hard. maybe 700miles per quart

 

what other signs would I notice if the rings were siezed? Car seems to run fine otherwise. Where would the excess oil be going... wouldn't it be noticed dripping from the car

 

Burnt off and out the endpipe..

Do you have any blue smoke when accelerating?

 

Hi,
to get an accurate "fix" that data you supplied needs to be confirmed
Have you owned the car long and is this a sudden thing or not?
Porsche state that up to 1.5 litres/1000 kms is "acceptable"

Plaese confirm

Regards

 

I just bought the car recently

 

I don't notice any smoke when accelerating

 

Is there any difference in oil consumption if you keep the engine under 4500 rpm's?

What's your driving style like, my GT takes quite a bit of oil when I do high rpm runs. No problem as long as I'm aware of it I guess.

 

I don't run it real hard or anything. Is this oil consumption a problem if I just always remember to check it and keep it topped off

 

do I need someone to look at the rings?

 

Pretty well known problem of GTS engines using some oil. Keep track of the mileage / oil usage for a time.......then see if it exceeds or is under the factory recommendations for oil usage.

Other then that if the car runs fine with no other problems you probably should just leave it alone and add oil when needed.

 

Hi,
there are other more qualified persons than I on here to offer advice

For me I would take a positive approach to establish the real situation

1 - I would do an oil and filter change using a known oil filter and oil
( I suggest a MANN filter and say a 15w-50 oil ) in a -10C to 40C environment

2 - Closely monitor what oil you ACTUALLY use. Keep the oil between low and full on the dipstick - only adding oil when the cold level is at the low mark. Note the oil used on a litres/1000kms basis and a litres oil/litres fuel used basis

Some engine flushing agents may help to free stuck rings/valve deposits and reduce deposits generally once you have determined if you actually do have an "out of spec." oil consumption problem

Many owners expect zero oil consumption - this is simply not an option with some engines!

I can advise you later of the most suitable flush treatment to use if you wish

Regards

 

Btw, there is a section in the user manual saying something like that when the engine is being run oil can get sucked up into the intake.. So I guess that if it's in the book it's a known fact.
