Put it in and went for a drive. The whining sound went away in 50 yds. I’m optimistic that everything is fine.

what a wild ride!
Does the trans take 5 qts.? I know mine takes close to 3 quarts.

I think mine took closer to 3 qts. Note that the filler plug is hard to find -- it's right in front of the left half shaft. There's what appears to be a filler plug about 5" from the rear of the tranny, at about 11 o'clock (rear viewpoint). Dunno what this is, nor did the Porsche tech know.

Good - I was worried there for a second

One tip for the future: gear oil smells a lot different than motor oil. It’s a lot more pungent and stinks quite a bit.

You know, having now accidentally changed your trans/diff fluid isn’t the worst thing in the world. Not everyone changes it often enough, so you are in better shape now.

Benefits of watching a DIY video first before doing some of these actions......

Right, arter, but I don't think there are any!

When mine sits at the dealer and drains for 30-45 minutes, they put back in 8 quarts and it is one or two bars down from the top every time. Car needs to be hot so the oil is thinner and will completely drain out. Just my 2 cents.

lovetoturn, that's sorta weird. The manual for my '18 718S says 6 qts. What model is yours?

981's are 8 quarts since the 6 cylinder is a larger engine with more oil capacity. They're technically 10+ quarts, supposedly, but only 8 drains out.

What made this error even worse is that changing oil at 500 miles is a complete waste of money. Porsche is conservative with their maintenance recommendations, and they specify 10K miles / 1 year for an oil change. I know that some believe that the first oil change should occur early to remove particles from the break-in process, but IMO if the particles were large enough to do damage to the engine, the oil filter would trap them.Moreover, since Porsche provides CPO warranties to 100K miles, I'm certain that they would recommend that the first oil change be done earlier, it it had any merit.

Eh, I'm in the change early camp too. Oil is cheap. Porsche engines are not. If done correctly (!), the only thing you're out is an oil filter and cheap oil. May not be absolutely necessary, but worth the small expense.

Pro tip:
The oil pan is at the bottom of the engine and the transmission pan is at the bottom of the transmission.

Interesting point. I changed the oil in my Honda pressure washer. The manual specified to change it after only 5 hours of first use. And lots of glittery grey oil came out. That engine has no filter either.

Yet, you’re right - if it’s not in the manual, then it cannot possibly be such a big deal. Does Porsche break-in these engines - wait, that’s not the right term...Does Porsche run these engines at the factory for a bit and change the oil before they are shipped out?

If the oil filter catches all of it, how does the oil you drain end up being so glittery and full of metal flakes? I changed the oil on my Subaru at 1k miles recently (also not called for in the manual), and there were lots of metal flakes and fragments in the oil pan when I drained. If the filter caught all of that, wouldn't it be in the filter rather than the oil pan? The oil is not stagnant, so you would think it would all eventually make its way through the pump and filter.

Indeed, but don't forget the warm, cozy bonding experience of changing your baby's first diaper...uh, oil.

Who knows what influences Porsche to specify change intervals? An effort to be green? A sales feature ("good for 10k mi.!")? The fact that they're not on the warranty hook beyond X years and Y miles (a cynic might argue that the best economics for Porsche is an engine that needs work not long after the warranty expires, PR aside)? A well reasoned thinking that, statistically, some high percentage of engines do okay at a longer change interval -- but not 100%? Etc.

I'm not mechanically inclined in the slightest but I've enjoyed working on a few maintenance items here and there on my 2001 Miata. Good vehicle on which to learn. Porsche is a completely different animal. I'm not touching it. There are no Porsche dealers in the state and only one Porsche specialty shop. Luckily it is local and has very long history and sterling reputation. They'll be the only ones to touch my car, and I'll follow whatever maintenance guidelines they set. Hopefully he doesn't need a new boat or lake house soon.
