Oil Questions?

[PorscheGAL]

Couple oil Question:

How long does it take for your engine to get to operating temperature? I appears it is taking my Turbo longer than the Targa to get operating temp. Is this normal of Turbos?

How much oil do you typically burn through during hwy driving?


Thanks In Advance Guys.

Depending on many factors and most on the outside temps, but I'd say 5 ~ 10' to reach op temps.

Between drips, passed through and burnt, may be a quart/1000 miles.

Good point on drips....I think I loose about 1 quart every 800-900 miles too. I feel it is thru leaks more than burning as my engine runs like a beast an no smoke even on start up.
Hard to fix all the leaks on a 30 year old engine.

It does drip but I am using maybe a quart for every 300-400 miles. It seems to be drinking oil. My Targa is 1 quart every 1000-1200 miles.

I only asked about the operating temp because the oil gauge only seems to move after about 45 min-1 hour of driving.

Forgive any stupid questions. Had the Targa for 4 years but the Turbo is completely different. I have only had that since December. Still learning all it's quirks.

Well that doesn't sound right. Mine tends to warm up after about 10 minutes of easy driving. Perhaps your oil temp. sender has seen better days, or the thermostat is stuck wide open. Any and all internal combustion engines are designed around specific materials and optimum oil temperature criteria...too hot or too cold are not where you want to be.

I wonder if a person could validate the oil temperature simply by taking the top off the oil tank and sticking in a meat thermometer. At least that would give you starting point for where to look.

But never mind all this if you live up somewhere around the Arctic Circle.

30-45 minutes to warm it up to the point where it should show an engine temp is way too long. In reality, you should be able to warm it up fairly well in five minutes of idle, follwed by a couple miles of easy driving in traffic...I find that if I let it sit there and idle, it seems to keep the oild pretty cool...perhaps a testament to the efficiency of the oil cooler. Warm it up for a few minutes then drive it judiciously for a couple more minutes. That should do it.

[Miguel Antonett]

The oil temp goes up rapidly until the thermostats open, which is about 175* and should show on the gage around the first bar (8 o'clock); if all is OK/normal, the temp should stabilize at that level unless... another can of worms...
If you don't see that needle by that mark, after I'd say 10~15 minutes of driving, you need to check the gage or sending unit because the oil is - at least - that hot, or so.

30 min. is all I thought it should. The targa is that way but the Turbo not so much. Oil Temp sensor gives me a place to start to diagnose the problem. thanks guys

Your turbo will be harder on oil than the Targa in regards to heat so it should be faster to heat up. In all respects the turbo is one car that has marginal oil temp controls as supplied to the US and I would replace the oil temp sender and look into getting an oil temp gage that has numbers on the scale so you know where your at. Look into replacing the front trombone cooler with something like the Carrera cooler if you don't already have it installed because seeing that you live in South Carolina you are gonna need it.
Oil losses like that indicate serious trouble. Are you sure the turbo seals are not blown and you are burning it all in the engine? Pull off the intercooler and plumbing to see if it is full of oil.....pretty easy thing to do as it is a few nuts and bolts that hold it on. If it aint leaking then it is burning oil, no where else for it to go.
