2024 Totals: "Post your latest oil change"

...Also in 2025, can we ask users to post whether if it is GF-7? This will determine how many early adopters there are and the number of die-hard users reaching into their stash.

I am pretty sure most BITOG users have an oil stash.
Running a GDI motor, I'm planning on using GF-7 as soon it becomes available at my Kia dealer or at the indie garage that I use for oil changes.

Regarding oil stashes: My last five cars did not use a drop of oil during their tenure, so every now and then a never-opened bottle of old oil turns up in my stash of automotive lubricants. Most recently, a 2011-vintage bottle of GF-5 M1 5W30 resurfaced...and, somewhere, there's a bottle of Total "Turbo Formula" 20W50, purchased around 1990, back when there were Total gas stations here in Michigan. It's probably next to the bottles of Type F tranny fluid that'll never get used.

Was surprised that the only OEM oils to make the list were AC Delco, Motorcraft, and Toyota. Honda lubricants do get mentioned on here from time to time, but didn't make the cut for whatever reason.

Throughout the year, I bet many Frankenbrews go unreported.
This is not to disparage the findings, just a guess.

Ha-ha,,,think of all the certs Frankenbrews might have!
More like think about how many oils have been ruined by mixing their chemistries with other oils 🤦‍♂️
I get it that sometimes you need to mix to use up old oils but we have a few members here who mix on purpose because they think they know better than the experts who built the oils 🙄 And in the end they are really not achieving anything at all.

I think it’s more about being a cheapo and thinking you have to use up everything. You cannot just recycle that quart of oil you picked up for 30 cents 10 years ago - that would be ridiculous.
 
Is that a certainty? I've read it here but can't recall the proof or even specific, known clashers.
I'd bet there are plenty of basic oils which would mix without bad results.
I’m not saying that the oils will ruin the engine but if you are expecting the oils to still pass the same approvals then that’s unlikely.

It’s just silly to think that the average person with no experience in the industry can play backyard chemist and actually make an even better oil. It’s not happening
 
We have no idea how mixing affects the resultant oils performance other than some tests showing very low temperature degradation with the particular oils tested. I can guess, give my opinion and assume. But no one truly knows.

.......and a whole bunch of other brands that had less than 5 users

These results are pretty accurate, although there might be a slight margin of error.
Have a Happy and Healthy 2025 BITOG Community.

Warren Oil makes a strong showing in 5th place: Super Tech + Kirkland = 119 total.
