I have been having problems with my oil level meter. I am unsure if I have too much oil or too little. Yesterday after I added 1 liter, the car started to overheat. I had never seen it go over 210 F. I stopped when it hit 250 F. I got it home by making frequent stops with the heater fan on. It was 25 C here in Finland, but the car has seen higher ambient temperature. It is a US/Cal model, so it has the front cooler. (Don't know if it was optional on the ROW Porsches)
I took it out of winter storage a few weeks ago. It backfired for the first time and it has been running lean ever since. After it warms up, if I release the gas pedal from over 3000 RPM, the engine stops. If I let it down slower, it idles as smoothly as usual and at exactly 900 RPM.
It had dropped some of its oil during storage. I am afraid of overfilling it. I've been adding 1-2 liters every week. When I drive it the station (engine over 170 F), the dip stick shows the min mark. After I add 1 liter and press the gas pedal for a few seconds, the dip stick shows no oil at all ??? After the second liter it shows the min mark again ??? When I leave the station or warm up the car, the level meter shows the red zone at first. When I accelerate it jumps to ½ and gradually exceeds 100% mark (which scares me). When I come to a traffic light, the meter stays at 100% until suddenly it drops to the upper red zone again.
My pressure meter is broken. I am assuming that the oil light is a too little oil pressure light. Therefore it would have warned it I have way too little oil. Right?
One last question. Is the official Porsche oil filter different than a generic filter of the same size? Does it have a different flow resistance or other properties? Or is it just a higher quality filter with small performance advantages?
