I typically spend about $25 DIY for full synthetic. It takes me less time to DIY then to drive to the shop and wait.

Well if your vehicle takes ~ 5 qts then with this deal you're paying about $13 for the oil, then probably $7 or 8 for the filter (I buy Purolator from Amazon and for my vehicles they are $8 plus they are eligible for S&S), so all in for consumables it's like $20ish. If you value your time (will basically always be quicker to DIY when you consider driving to a place then waiting), and you have the tools and space, yeah it still makes sense.

Local auto parts stores take used oil. Drop mine off at my local auto zone.
This is correct. O Reilly down the street will dispose of it for free.

Seems like you answered your own question. My daughter just paid $70 for an oil change that probably would've cost me $35 and 5 minutes of time! She has a Jeep so it's a piece of cake.
calling b.s. on "5 minutes". At least 20-30 minutes real time start to finish.

20-30 minutes?? Ok, "real time", maybe 10 minutes, which includes carrying my tool box outside. Like I said, she has a Jeep so no jack needed. If you'd like I'll videotape it next time for ya. I also have drive-on ramps for my other vehicles. If you're taking 30 minutes I suggest you just take it somewhere! 🤣

Quote from CrimsonHarrier157 :
Same here. I remember seeing a youtube video of a guy cutting oil filter brands open and surprisely enough Walmart Supertech was actually decent build and material, and Fram being dead last with cardboard/paper filter. So I've been using Walmart Supertech oil and oil filter for more than several years and so far my truck has over 220,000 miles and still drive it from time to time.
I would also like to say that I preferred DIY maintenance knowing I've done honest work. Cost me about $25 oil + $5 filter + $5 motor flush = $40 w/ tax and about 40 mins. I do all my family oil change. Oh and to dispose it I have leftover empty 35lbs frying oil plastic containers, just pour in the used oil, and bring it to any auto parts store. Not really hard honestly
I hope you have clearly labeled the container so there's no accident.

An oil change takes 45 minutes for most vehicles.
30 minutes tops for most I have worked on and that was leaving a lot of passive time for draining. I walk away and do something else.

You can wait an hour at a oil change place before they even get your vehicle on the rack. I've noticed some of these places are only vaccuming the oil now as opposed to draining it. Takes longer.

Watch these places too. Last time I took a vehicle in they didn't even fill it fully. Must be shrinkflation.

I have a question for the car pros here.

If my car has been on traditional oil for ever (100k miles), is it bad to switch to full synthetic now? I heard switching to full synthetic after your car has been on conventional oil will cause leak because synthetic is smaller molecules than conventional and will "slip" through all the tiny cracks.

If there is a spot where oil could leak out in your engine, then synthetic oil is more likely to leak than conventional. However, synthetic oil would not cause the leak.

Used Kirkland oil in a 2016 Toyota Highlander last oil change. Started noticing a little engine tap at idle after putting some miles on it. I know there's data out there that says all the synthetic oils are similar but I'm going back to pennzoil ultra on my next change.

For my corvette (10 qts synthetic + good brand filter) it's even more. Doing it myself works out to about $45 + the satisfaction of doing it myself and knowing drain plugs aren't over tightened, etc.

I do go pick up the oil in my Tesla…
And I was a GM tech and you probably have more knowledge and pride in your work!

Unless things has changed I know few years back most places don't fill it fully usual 3/4 to the full mark and call it good.

How long does the oil keep? This is about 2 year worth of oil for 2 cars.

Is it still worth to do your own oil change nowadays? I called a dealer near me and it's $100 for an oil change!
Yes, it cost me $105.00 to change the oil in my C8 where the dealership wanted $250.00. It only takes 30 minutes at the most to change the oil.

Depends on the filter. The ones that replace the just the filter element takes longer because you have to drain the oil from the filter, then open it, replace the o-rings and filter. That adds about 10 min to the job.
