My thoughts as well!


The value of a scientific theory is its ability to prompt further study, not that it has any relation to the established facts of scientific reality.

It is a shame others categorically dismiss ALL additives as "snake oils". Thats simply not true. Restore is one of the good ones.


Well, it might be good in some cases, to get another year out a beater that's on the path to the junkyard anyway, but's pretty clear adding Restore to a good condition engine is either useless or harmful.

How is that "pretty clear"? Source of that statement?

Restore does not harm anything. Even in older engins that still run pretty well it improves compression.

That's kind of my feelings too. I haven't seen any evidence that it does any harm other than in something with vvt.

I ended up putting a bottle in my Caprice with the 305. We'll see whether I notice any difference. Unfortunately due to weather I wasn't able to do a compression test before. If I end up trying it in my summer car which I know has slightly low compression due to age, I will do a before and after compression test. The Caprice idles smooth as glass so compression is probably fairly even on all 8 cylinders, but it has pretty significant cold start piston slap, and very slight oil usage so it has some wear for sure after 233k miles.

I've tested this stuff on shop engines. We had one dog that was 131-145 psi. It's 194-206 psi now.

Its hard to argue with that. That difference is significant enough that it may well be worth trying on a bone yard refugee. Nothing seems to be harmful in it like chlorinated paraffin's so no harm no foul trying it and its not some $100 a bottle snot.

I have also used this stuff in the past and it does restore lost compression to old/worn engines.
If I was unable to rebuild or replace a worn engine and needed to continue its service, I would definitely use Restore.

used it on a 72 ford courier. Ruffle every 5 to 7 thousand miles, it starts smoking. Throw in a v8 size can in a very sloppy 1.8 liter, works great.

Can help with compression for a while, but the bearings will get black of friction by grinding out the "soft" metals embbeded to the babbit and the jornals will get all fine polished/scratched... Ask how I know that...

That's quite a trade off but if the engine is on its last legs anyway I guess it doesn't really matter, something to think about though before putting in an engine that really doesn't need it to gain just a few psi.

OK, I will bite. How do you know that??

I have used it long ago. It works on worn out engines. Brings up compression, runs smoother.
