what is your easiest and most difficult oil change?
 

I have both sides of the spectrum now.

easiest is my 2006 Toyota Tacoma. 4.0L. oil filter is on top of motor. I turn it off like the lid of a pickle jar. slip under, and the drain plug is right there. pow!

biggest PIA?
my 2023 Toyota Tacoma. 3.5L. it has a canister type filter where I only change out the element inside. canister is plastic. I have to drain it first by removing some odd alloy cap and then jamming a draining device. I had to source a sllicon hose to keep the oil from dribbling down my arm. BUT to even get to that filter is to remove the skid plate. grit and sand will rain on me. haha. I have to change out o-rings on the canister. two of them. the oil fill tube is very angled. I have to get my wife to steady the funnel. good times!!

I changed both a couple of days ago. my 2006 took 7 minutes. I'm still side eyeing the new truck to make sure I didnt forget something. :D

wife has an EV. high five.

Chevrolet 3.6l V6. Hardest and easiest.

My wife's old 2016 Impala had the oil filter wedged in with the front exhaust manifold, about an inch from one of the catalytic converters. You could unscrew it from the top, but you couldn't lift it out between the engine and radiator. A couple times I dropped it after burning myself and splashed oil everywhere. The drain plug was almost horizontal. The first time I pulled it oil shot straight out onto the inside of the right front tire. After that I found I had to hold the pan up to catch the first spurt of oil.

Same engine, 2021 Blazer. The oil filter is now on the bottom of the engine, and the drain plug is also on the bottom. No muss, no fuss, easy.

I always hated the later model Volkswagens and Audis that I used to own. I always had to pull a big plastic under tray to get to anything.

Your 2023 sounds like my 2016 Tundra. Not a bad job on a lift. Toyota filter comes with a spout to drain the oil out of the filter before removing it.

Worst oil change? 2010 Ford Ranger. Oil filter is in the wheel well just out of reach and crooked in everyway. Dropped a full oil change on the driveway because I didn't have it on properly. Oh, and it was a new driveway. I moved so I didn't have to look at it.

You need one of these....

Both Honda's
My 98 Prelude is super easy. Can reach both the drain plug and filter without even lifting the car.

My 23 Civic could be the same...except it has that belly pan that needs to be removed first. Seven fasteners, two diff kinds, need to be removed first. I have to use the lift for that car.

I swear by these. Makes oil draining a snap....

Generator. Have to remove the housing and elevate. I should definitely invest in a pump.

I have 1 of those on my 84 Carrera..... Makes an oil change very easy.... Because you can regulate the outflow.

Lotus elise / exige.

Its not hard but it takes a lot of care, jacking up car is a bit of a process and there are like 25 tiny stainless fasters to be carefull with for the undertrays.

It always took me 2-3 hrs.


Ive never had a car where I didnt have to remove some sort of under belly.

Same, wife has 2018 Subaru Outback with 3.6L flat 6. I don't have to jack the car up, slide under, unscrew filter bare handed through access hole in plastic panel. Then use a wrench to remove/reinstall drain plug. Fill with 7 qts of oil.

2008 Boxster S w/3.4L flat 6. Jack up car, because there's no way in hell that I can fit under it any other way. It also has a canister oil filter where you just replace the cartridge. LN Eng does make an adapter for a screw on oil filter, but I'm sticking with the canister for now. The screw on filter would be a lot easier/cleaner. Fill with 8.2qt of oil.

The worst oil change is the FIRST time you charge oil on a 911 and realize your drain pan is too small!

All of my cars have been as good as can be reasonably expected.

Most difficult: 2013 Porsche Panamera GTS. Disable air suspension. Jack up. Remove belly-pan (~18 screws). Remove structural cross brace ( ~6 bolts ). Drain oil. Change filter. Re-assemble. Fill oil. Plug in computer to reset. Check and confirm oil level several days later once all conditions have been met. (currently owned)

Least difficult: Kia EV6 ... no oil since its an EV ... now at 40k-miles ... this is an awesome car that is now super cheap on the used market ... It drives well. All of you should go buy one ... best daily appliance ever. (also currently owned)

Worst used to be my Land Rover Discovery 4 (AKA LR4), until my mechanic told me about the extractor tube that sits just under the fill cap. I had no idea what that tube was nor that it went to the oil pan. I had been taking off the heavy belly pan to access drain plug prior to that knowledge. Now it is just suck out the oil from the top.

Easiest is my older Discovery 2. No belly pan and very easy access. The filter is a bit of a faff though since you have to wiggle it between steering links and spill all of the oil out, but it is very accessible.

An under belly on a 84 930??

My Yamaha outboard.

My 2020 Ram is a pretty big PITA. Drain plug is easy but right above the sway bar so it pisses oil everywhere. Filter is high up on the block above the suspension and power steering rack, so it drips all over everything. I now drape a trash back over the components to get most of it into my pan.

I've got a drain pain that holds, I think, 12.5 qts. It even has a little vent. But if you don't tilt the thing a tiny bit so that the corner with the vent is higher, the hole can't keep up with the volume of oil that's coming out of either of our cars and the big "funnel" overflows. That's damn frustrating.

Nope, previous vehicle mentioned in his post.

I'm pretty sure that I've seen a pic of that oil draining on the 'Net as a meme for mechanics wanting to kick the aß of engineers.

^^^ his sig says he owns a 84 930
My 84 does not have one.

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...
