People with high mileage vehicles who run supertech full synthetic oil

2005 Honda Odyssey. Has seen one non-synthetic OCI in the entire 19 year period I have maintained it. Uses no oil at 220k miles. Mostly PP in the 2010s, but at different points it has seen M1, Redline, Amsoil, Rotella, you name it.
I'll forgive someone for thinking every oil is the same if they have no experience to the contrary. Heck, I work with engine engineers who mostly think it's a commodity.
But if you have the experience I've had with VRP cleaning an incredibly varnished minivan engine, you'd never think that way again.
it's an oil additive known for engine cleaning, it was all the rage here on BITOG a decade or so ago. I think it was subsequently shown to be mostly a printing press chemical of some sort, my memory is fuzzy.
Regardless, it worked.
Many old threads as @Hohn said if you search. It had directions of cleaning with it by adding to regular oil, rinse for X miles with conventional, repeat and whatever else. Some gave it the snake oil thing, some said it was better than indoor plumbing. Whatever it was, for me it worked as directed and reduced burning a lot BUT that was about 20 years ago. Many developments since then.
I think a big change since then is low tension rings, old members here finding burning issues on what is thought of as very good full synthetic oils. Someone might have posted in this thread or another VRP predicting fad with clearance sales happening by end of last year. Ignore the it ruined my engine from sludge videos.
I agree that VRP is extremely good at cleaning tarnish and carbon deposits, my vehicles and the ones i maintain have never seen excessive tarnish so I haven’t had any reason to use it. For me that premium price point of VRP is not necessary for my vehicles.
Here is my moms Subaru Outback 2016, 150,002 miles, mainly Supertech 0W-20 FS HM, 10K OCI. Lots of city driving, no matter how much I try to convince my dad to change it at 5K miles he insists on 10K but oh well, not my car.
The little darker spot is just because oil sits there and cooks because its a little dip and cannot flow out of it.
That's the best picture I could get but even past the oil filler tube it is surprisingly clean.
Looks great! My friend has a 2024 Crosstrek with under 20k miles that looks worse.
Definitely because of you guys' severe conditions, where I live is pretty sparse and you rarely even get stopped by lights if you take the right routes which we try to do as much as possible. Back roads around the city for the win.
5 or 6 years ago, I ran my 2009 Ford Focus 15K miles on SuperTech 5w-30 and got a stellar UOA back suggesting I could run it another 2500 miles! I ended up going to HDEO but that one UOA showed me that Supertech is right up there in oil performance and long life.
Holy crap a 15k mile OCI is very long, what made you want to run that many miles on the oil change?
Yeah this stuff looks professional, that's why I haven't seen it before probably. Good to know about it if I ever have an issue like that.
I think any engine ever will get a golden hue eventually except maybe if you exclusively run VRP. I saw a guy with an 07 camry with the 2AZ-FE that was burning extreme amounts of oil pour chemtool b12 directly in the combustion chamber, let it sit, then crank it over with the sparkplugs out, rinse and repeat a couple times and changed his oil afterwards and it freed up his stuck rings. Could be a good strategy if you own one of these.
Referred to as a piston soak. Discussed many times in the threads.
2010 Forte with 2.0L with about 185k on it. Not too golden colored.
What's the oil change history on it? Looks pretty good.
The 2nd owner I bought it from used mostly Pep Boys but said he did 3-5k changes with synthetic, lots of highway commute. I have no receipts. I bought it for my son with about 140k on it, mostly PP and M1 since then with about 5000-7500 mile OCI’s. Now has I think 193k.
Picture is from February when I did his VCG with spark plug tube seals. It’s in a thread somewhere here. VCG and tube seals were solid not flexible any longer. Maybe it was golden before the following? It did see one BG EPR flush probably a year before that and I think 2-3 OCI’s with 1qt HPL EC30. I have pictures in filter thread or EC30 thread of the carbon stuff EC30 helped clear. Last OCI it is now on VRP 5W-30 and I’ll probably stick with that and somewhere around 5k changes depending when he is back at my house if he brings it. It’s now 8 hours away from me in VA and his commute is .6 miles each way. He goes home for lunch so less than 3 miles/day. It does see weekend drives and like this weekend will see a 1500 mile round trip to upstate NY cabin.

Survivor bias is a thing though.
