Or do they use the regular 0W-40 formulation? I've read conflicting information and instead of just taking the dealer's word for it, I prefer to "trust but verify." Does anybody know for sure?

Dealers mainly use A40 Porsche approved Mobil 0W40 and Pennzoil 5W40.

I'm using Mobil, Motul 8100 X-cess is an excellent product too, I just noticed Wallmart online sells it now with free shipping.

The "European Car Formula" is A40 Porsche approved, I believe. I just changed mine Saturday with two 5 quart jugs from Walmart (7 quarts used of the 10).

What's the difference between Euro car formula and regular? (I have used both.) (Just bought a 5 quart jug labeled "european car" for $27 shipped from amazon.)

'Euro Formula' is no more. Mobil changed the formulation a while back, adding a minuscule 'FS', but the aholes kept the misleading name. If you want details, go to BITOG, but it was reportedly more like a 30 weight than 40 now. And yes, it used to be great before the change. I had 2 jugs I bought a while back, so just used them, but next time will buy smething better, that helps eliminate the common 'rapid ticking'; we'll see. By the way, I used 9 qts after draining oil for 3 hrs (got out approx 9.25, with oil level with all 4 segments lit).

Did you do that on a lift? I used ramps on the rear wheels, which tilts the car a bit of course, and could only get 7 quarts out after well over 2 hours of draining (it was barely dripping at that point). I measured the removed oil to be right at 7 quarts.

Edit: I did not account for the oil filter. Perhaps it had 1/2 quart or more.

The oil filter housing with oil filter in it holds more than 1/2 quart. I don't think it holds an entire quart, but definitely more than 1/2 quart.

EDIT: Did an oil change today and measured the capacity of the housing. It will hold a little over 8 ounces with the filter inserted in the housing. Sorry for the mis-info.

Mystery solved thank you

I was wondering that. I use the same method, but lift the front with my floor jack with a Porsche 'puck' on one side, and with my jack kit (behind the passenger seat, where it causes no seat restriction. It was from a previous gen Cayman that was never used) at the other. You absolutely need the car at least level, to get most of the old oil out, but I actually tilt the car a bit more at the front (as high as the car's jack allows me with a 2x4 underneath), to do it a bit quicker. Yeah, 1.5 to 2-qts difference is A LOT. You left like 1/3 of the old oil in there; not great. By the way, you could lift the car with the floor jack alone, but since I leave it raised for hours, prefer the chassis is not twisted that long, hence using the car's jack to level it off. Hope this helps.

Is it better to keep the car level when draining or tilted? If tilted, which way?

PorscheAddict

Mostly fair and a helpful discussion, but I have not seen a single report of someone getting more than 8-8.5 quarts out regardless of tilt/temp/technique. That's still ~25% of the old oil in there, assuming it really is 10.7 quarts as they claim. More importantly, I did not account for oil filter, so I really got at least 7.5 if not closer to 8 quarts out, which is basically the expected amount. I haven't ran the car since, except to move it off the ramps, due to temperatures here, but I expect I'll be adding another quart (added 7 of fresh).

Correction to my previous post: The oil filter housing with filter inserted will hold a little over 8 ounces of oil before spilling over the top of the housing. I made an edit to my earlier post. I did an oil change today and measured the capacity of the housing with filter. Sorry for the mis-info.

I always drain my oil with the car sitting on Liftbars with 4 floor jacks set to the same height, rear of the car towards the outdoors in the garage. The car is therefore sitting slightly lower in the backend due to the typical slope of garage floors down away from the interior of the home. So the car is maybe 1/2" to 3/4" lower at back than front, I'd guess. I let my oil drain for at least 2 hours, sometimes 3 or 4 depending on what I'm doing. I always get 8 quarts plus another 30 ounces of a 9th quart in to bring the oil level up to just where the 4th green segment switches on. Always change the filter too. IOW, I get 8.9 quarts in with oil and filter change, with a long drain and the car sitting slightly lower in back than front.

Now you did. I've gotten over 9 both times... BUT it depends on 2 things: How full your sump was (I always have 4 bars myself), AND how long you drain. Again, the oil doesn't stop streaming until past 2 hours, at least on my car with hot oil (the way it should be drained). It takes over 3 hours for oil to start dripping slowly. Finally, even at the 4th bar, depends how full that segment is; each segment holds 0.45-qt, FYI. This time around I just put 9 qts (probably barely triggering the 4th segment), so I should get a little less than that out next time, due to the oil filter and housing holding some.

Drain plug is at the rear, so if car is going to be tilted, it better be at the front. I only tilted it at the front a little bit, maybe 2 inches; just enough to make sure it's not tilted backwards, and oil flows to the rear. You don't want it tilted too much to the rear either, since drain plug is not at the very rear, but more like 1/5 of the way rear to front.
