Air/Oil seporator & remote filter

[kentgreer]

I had a airwolf air/oil seporater installed so I could keep the ninth and tenth quart from oiling the bottom of N21396.I also had the mech. install a remote oil filter on the firewall.Has anyone had this done so I can compare install time.My guy is sticking it to me for this.

I'm surprised you are doing this. I added a remote oil filter, but by filling just to the notch Todd files on the dipstick, I do not need to add but 1/2 quart every 30 hours of flying. Not too much is going on the belly.

If you fill above the notch, it will all get blown out though.

That's Dean Georgaris' former 260se! Very nice airplane, with an excellent panel (http://www.avionicswest.com/panels/cessna182/05252001.htm#2001) that was state of the art six years ago and still top-of-the-line today. In fact, I designed n812kt's panel (http://www.260sepilots.org/gallery/N812KT-Moore/aah) with this one in mind, except for the HSI's and a STEC30 instead of STEC55. I flew it for Dean to the Sedona Fly-In in 2002 and it was a great plane to fly. Hope you're enjoying and taking great care of her!

How much oil do you add at your oil change?

Todd puts the notch at 10 qts and advised to only add to that level.

If I could keep 10 qts on the stick{plus 1 for the filter and lines} I'd be a happy camper.It seems to hold steady at 8.

Here's your answer from an article at AVWeb by Mike Busch on this very issue:

You might wonder why TCM puts a 12-quart sump on an engine that requires only 6 quarts. The answer is that FAA certification requirements demand that the engine be designed to hold twice as much oil as it actually needs:

FAR §33.39 Lubrication system.

(a) The lubrication system of the engine must be designed and constructed so that it will function properly in all flight attitudes and atmospheric conditions in which the airplane is expected to operate. In wet sump engines, this requirement must be met when only one-half of the maximum lubricant supply is in the engine.

The TCDS for my TSIO-520-BB engines states that maximum acceptable oil consumption is about one quart per hour. If my engines actually used that much oil, then I'd need to fill the sumps nearly to their maximum capacity to ensure that I had enough oil to make a 5-hour flight without risking oil starvation. But since I know from long experience that my engines use about 0.1 quart per hour, there's no reason for me to carry anywhere near that much oil.

Every aircraft engine installation has an optimum oil level at which oil consumption is minimized and the engine is happiest. I would encourage you to experiment to determine what oil level works best for your airplane. Your engine will operate properly at 50% of its maximum oil capacity -- guaranteed. As long as you keep the oil level a quart or two above the 50% point, your engine will be happy.
