As an engineer it makes me want to punch an engineer.

good point how could I forget that one.

I'll nominate that as my easiest one for sure. Just gotta buy an imperial crap ton of oil.

993 - has two oil filters.

The larger one screwed into the oil tank isn't difficult, just need to remove a couple plastic panels. The smaller oil filter is a bit a pain because you need to remove some heater ductwork that's in the way. You're supposed to disconnect a hard oil line as well but I always leave it in place and then you have to maneuver the little filter out and down out of the way, usually with oil dripping out of it in the process.

911s from 1989 and earlier are a breeze by comparison.

my duramax and its 10 quarts. even barely warm it comes out in a torrent like a garden hose on full blast of black, nasty, staining all it contacts devil spawn. If you don't "cushion" the bottom of the catch pan it exits the thing as quickly as it enters splashing everywhere. I save my old swamp cooler pads to line bottom of my drain pan dampen the velocity.


Also save large pieces of cardboard to lay on and down to save myself cleanup.

Easiest? Any rig other than the duramax...

Ive had mostly small block Chevy motors. All pretty easy. The 3.4 in my Cayman, not bad if you drive it up on a couple 2x10s. I did have the pleasure of cleaning up the mess the first time the hole in the pan didnt keep up with the flow. You only let that happen one time.

My first gen MR2. Its mid engine, some smart guy at Toyota decide to put the oil filter under the exhaust manifold. Talking about contortionist. Tiny bit or couple degrees at a time with a ratchet, with my arm twisted in there in the middle of the car. No access from the bottom unless I remove the entire engine. Spill is the norm, there's no easy way around it.

Porsche 993 is definitely not an easy oil change. Two filters (the little one is tricky to get to and always drips down my arm) and the big filter is easy but you really need to remove plastic trim bits, along with the right rear wheel and forward fender liner. Also, the engine only takes the new oil in slowly and can burp it back onto the right side of the engine if you pour too fast. I can see why the dealers or indys charge so much to do an oil change.
The Porsche 997.1 is so easy to change it is a breeze! One filter, oil goes in easily. No dip stick is a feature you have to get used to (reading oil level on a gauge on the dash). Something I have learned is that the 997, like the 993, doesn't like the oil level to be filled to the maximum level, it will smoke on startup as the high oil will migrate to the cylinders at rest.

Add a Fumoto valve . I did on my 2001 Duramax . It is a piece of cake to drain oil . A little slower but 100 % under control . I am adding one to my S10 with 5.3 Vortec as that is a side gusher .

Yeah, my 6.0 Ford is 15 qts and impossible without a Fumoto. My drain pan only holds 10, and anything more becomes unmanageable.
Easiest? 911 by far. Hardest? Any boat, but particularly a sailboat. Need a vac pump down the dipstick.

I have twin Mercruiser 6.2s in my boat and it’s super easy. The dipstick tube has male garden hose threads on top for an extractor, I rigged up an adapter to the one I have for cars. It’s a little over 5 minutes cold, not much pumping. Oil filter is on top, super easy. Pretty much all of my boats haven’t been bad but the extractor is key.

Yeah, I/O powerboats have motors designed to take an extractor. Most sailboats have small diesels that aren't. Combine that with dual fuel filters and the need on some to bleed injectors...yuck.

Sort of what the op asked...
I changed the oil in my car in the garage. The old oil filter rubber gasket didn't come off with the filter.
I screwed the new filter in. As I am backing the car out of the driveway, I see this long line of oil following me.
Very young and learned real quick.

Not mine, but I've helped my brother do oil changes on his Mini Coupe and it's horrendous. Every vehicle I own is pretty easy to complete an oil change but my 2012 F250 is probably the easiest since I don't have to remove any under body plastic parts to get at the filter and drain plug. Plus, before I had a two post lift, it was the only vehicle I didn't need to jack up or use ramps for. I could slide under it on a creeper, drain the oil and change the filter.

Oil change onthe 356 is trivial, as is on the RAV4 and all the other vehicles I've owned (not that I regularly do my own oil change, and now I have my son to do it)

Biggest issue I had wiht the 356 was finding a filter with a proper gasket to seal the top, took a couple of tries.

The RAV4 needs a crush-washer-like thing on the drain plug apparently, my son says the filters/kits at the FLAPS often don't have it, so I have him get me one from his work when he does my oil change

Easiest is the El Camino. I have done over 100 oil changed on it. I do put it on the lift to grease the multitude of grease zerks on the suspension.

Most time consuming is my wife's Macan. Lots of torx screws to remove and a few large plastic fasteners to remove the underbody pannel.The oil drain is easy, but the large cover is just a pain to get on and off.

I hear of people shoving a hose down the engine and sucking the oil out in a short order. The oil filter is a cinch. Right on top, with a large nut to help remove the lid, and replace the cartridge. Overall pretty easy to do.

My business partner has a Miata. The oil drains ring onto a crossmember and just makes a mess. I have let him use my lift and watched as he changed the oil. I put a large metal oil drip pan under his drain pan. It is just bad design to have the oil drain out right onto the suspension member. They did not think of the mechanic at all for that.

My Jeep Wrangler is definitely the easiest. Can lay right under it,to get at the plug, reach right in, filter is right there in the front. Piece of cake. Wife's mereceds is a little bit of a pain, o ly because you have to pull the belly pan underneath it.

Worst I remember was a Chevy Citation. The filter was on the back of the engine hidden on top of the transaxle, Total pita to get at. When you unscrewed it, oil poured all over everything.

.

My 911 is pretty easy.

My son's 2023 tacoma is a pain because of the metal skid plate. I never drain the filter with the tool.

I have questions

You don’t drain the canister at all? Or you use the special drain spigot thing?

And you change your kids truck oil? :)

Another good thing to have is a "low profile" lab carboy as a drain pan for oil. If you know anyone who works in a lab they might be able to score one for you.

Drain into the top hole and empty from the spout...

Yes, I have failed as a father.
