Who changes their own oil here?

I use my Jeep and truck to do a lot of volunteer trash pickup in the Willamette National Forest and surrounding areas.

We're always finding jugs of used oil, coolant...even sealed up new bottles...but the best one was stumbling upon a 55 gallon barrel tucked behind a tree in a remote campground...sealed up...we rolled it up some ramps and drove it to the transfer station and haz mat place in Eugene.

One full barrel of methylated urine. Yes, boys and girls and its...meth heads collect their piss and extract the good stuff for a second run.

Really glad that barrel didn't leak. Excuse the pun.

So...used or new oil on those filter rings... (That should keep y'all busy for a few more pages.) Or dry!

This means there are people who do eat the yellow snow.

Speaking of filter filter ring/gasket. I have changed oil myself in every vehicle I have owned for decades. I've had two 4.0 L TJ's and I use the Mopar 090 filter on them. I have had at least 2-3 of these Mopar filters that leaked after I put them on and had to tighten with the filter wrench to get the leak to stop. Never had that with any other vehicle/brand of filter ever.
There seem to be a lot of vehicles that have to correct seal diameter and thread size to accept a Motorcraft FL1A. I've used it on every engine it would fit on for 20 years, including a Datsun, my Jeeps, and a number of older Fords and never had an issue once.

Yep, right there up front and down low, with it's own little oil catch so it doesn't puke all over your engine block. My wife had a Scion FR-S for a bit (Subaru engine) with the oil filter right on top of the engine facing down so you could just take it off after a drain without a mess. Pretty neat.

I've seen enough shady mechanics in my life to not trust anyone but myself to wrench on my things, unless it takes specialized tools or experience. The more you know about the state of your vehicle, the better you can address it when things go tits up.
My wife's first 4runner, a 4th gen with the 4.0 V6, was that way. Even had a little dam that directed the oil down a hole so you could catch what did leak out. Then the 5th gen came out and they "updated" the engine with a cartridge filter hidden behind a skid plate and dumps oil down your arm every single time. Not only does it make a mess but thanks to the skid plate and the cleanup it turned a 15 minute job into an hour. It's the only vehicle I've ever had that I'm happy to pay $100 for somebody else to deal with it.
 
37 years as long as I have been driving I have never paid for any oil change on any of my vehicles, the only time someone else has changed my oil was on my Wife’s 2020 toyota as it is free for the first 2 or 3 years and after that I will be changing it as well.
 
I heard the best way to check your oil is by a 3rd party dipstick.

Works for TJs also.

Not typically - most heavy metals won't readily dissociate in PG or EG mixtures and any concentration would be de minimis in nature. Most metals will readily flocc and will precipitate out of solution anyways.
I have no idea really, the EPA tells me this shit and I say, "okay."

It isn't by mistake as you know. If you want the same awesomeness of the FL1A in a Mopar sized package the FL300 works. If you get really rough I guess the filter could knock your A/C bits or something? I am a huge Motorcraft filter fan, holy shit, best filters ever.
 
My apologies, the contextual thought processes of your wife's boyfriend taking her car to Walmart for ya'll distracted me from anything you wrote after that.
I did not catch that. I meant bestest friend.
Thank God and the Admin for the edit feature.

I change my own oil all the time. It's cool as long as you follow this advice I found on the internet.

That’s were the shit came from to begin with, the ground.

As a kid, I remember going to my uncles ranch in eastern Colorado, they lived on a dirt road, he had a tank hooked up to a tractor with a spray boom attached.

When he got enough oil in the tank, he’d drive along the dirt road spraying they oil, he said it kept the dust down. Fifty years later, you can still drive that road with minimal dust.………!
 
I do it the stupid simple way. When you get the old filter off, set the new filter right on it ring to ring and give it a little twist. Done.
I think unless you clean the mount you don't need to do this. I used to do it because that's how I was taught. One day I realized the oil filter mount had oil on it too. I guess if you don't hot swap and clean it up or something you could have problems but it's never caused me any issues. I'd definitely call my way stupid simple and yours more traditional careful.
 
I went to the store and just got back and now there’s 135 posts on this thread about changing the oil… I’m glad the original topic wasn’t I need someone to help me name my jeep… 🤣

I have not done oil changes myself for many years but with the TJ I have started again! simple job plus you get to look for glittery bits and worry yourself stupid if you overfilled or not, also gives you a good excuse to lift the hood everyday to keep making sure that hand tight only filter isn't leaking. :)
