Valvoline Restore and Protect
I'm trying out this oil in 5w30. I put some in late last fall and haven't even broken 1k miles yet. Probably not a good test but intend to use it for a few more oil changes at once a year since I put so little miles. The idea is it needs several changes to truly "clean" an engine.
My engine has 157k miles as we speak and when the car was my daily driver, it didn't burn too much oil. Maybe 1/3rd of a quart in a 6k change interval. I do have a burned exhaust valve and last checkup revealed deposits on cylinder #4. I hope this can at least help clean it up a bit.

This oil is a good choice if you think that your piston oil control rings are frozen / stuck in deposits. It does happen and the S2000 motors can certainly consume oil. It is a good idea if you can get those stuck oil rings freed up. The problem is that most people can't tell if their rings are messed up or not. Still worth a try.
Never done this I'm guessing?
Test results can be reassuring -- or terrifying!
Oil analysis will highlight what metal parts are wearing at higher rates than usual -- for example Blackstone Labs has a data base of all the S2000s they've tested and has established a "normal" or average for our engines . Also if the oil is getting adulterated by dirt, antifreeze, blow-by (bad rings),etc. And if the oil is beyond it's "use before" date.

But how would it help specifically, in context of this thread? And what are the uses for what it provides?
Or are you just curious as to what an oil analysis shows?
TBH, I think its a used oil analysis useless data point for *most* cases.
I'll be changing the oil again this fall. Not sure if I'll feel a difference even after a full clean but judging by everything I've seen or read on this oil, it should really help a high mileage engine, although does not fix my valve problem. Looks like it can also help a poorly maintained engine with lots of deposits and "restore" it to a newer condition.
I intend to use this oil in my newer daily driver after I finish my current stock of oil jugs.
The additive in the oil supposedly dissolves carbon, turns it into a form of graphite smaller than 3 microns. There was a snake oil additive back in the day, I forgot its name, LD20 or LP50 or something like that, which supposedly did the same thing. Some people swore up and down that stuff worked, I guess they put that additive in this oil.
seen some decent oil burn reduction in Toyota 4 cyl motors in customer cars. early 2000's camrys burn oil like its gas with higher mileage. this is after 10k ish miles with constant topping off with the VRP. those Toyota motors are known for rings getting stuck so my guess is this is helping in that area.
