Like the title implies does anybody have any knowledge if it’s common practice to use Engine Restorer to bump compression when selling a used engine? For those not aware of the product (like I wasn’t) it “fills worn areas of the cylinder walls to reduce blow-by and restore compression to near original levels.” Bottle looks like so.
A bit of backstory, I bought an NA Miata a few months ago that had a used engine with 103k swapped into it, and I have had no issues so far. However I had Blackstone Labs analyze my first oil sample after 3400 miles and they came back with this
“Copper and lead are off the charts in the first sample from your Miata. These metals suggest excessive bearing wear, unless you added some Restore at a previous oil change. The additive contains a lot of copper and lead. If you haven’t used Restore, we’d be concerned about a bearing problem. Lucas explains the thick viscosity, and that’s fine. Silicon looks more like a harmless sealer than dirt, but it wouldn’t hurt to check air filtration. Averages for the engine type are based on ~3,700 miles of oil use. Any knocking sounds? Check back in 2k miles if all is well.”
I’ve spoken to the previous owner who did the swap and he said that he never used the product which doesn’t leave me with a lot of hope. So the only line of thinking I really have left is that whoever sold him the engine added some Restore so that if it was compression tested it would appear to have healthy compression. If anybody has any insight I would appreciate it.

At this point, I wouldn’t put much stock in products like Restore. I'd at least do a physical check.

Do two or three 800 or so mile changes with full synthetic and a GOOD filter. Run the Blackstone test each time. If it doesn’t get better, well... sad panda.

Hopefully not. Products like that are a full blown scam, just look at all the proble ms radiator stop leak causes

“Restore” is one of the few products that actually seems to work as advertised. I’m surprised. There’s a lot of snake oi l out there, and I thought this was going to be just another one of them.

I’ve used “R estore” on some of my own vehicles, but I can’t say I’ve ever heard of someone using it just to help sell a car. The stuff has a very noticeable blue color; even when mixed through the rest of the engine oil, you can tell that it’s there.
I’ve never actually confirmed its effectiveness for myself, so all I’ve got to go on is the ol ’ butt-dyno and these Project Farm videos . Which makes me think- if it really does work so well, why use it just to sell a car? Why not enjoy those benefits yourself for a while before putting it up for sale? If nothing else, it would give you a chance to change the oil again to get rid of that blue tint before somebody notices.
