Well a machinist I know has torn engines down that they have used this product in the entire time and couldn't believe how clean the internals were. Sounds like a good additive to prolong the life of the engine.

A quality motor oil or even better, a good synthetic motor oil is all that’s needed along with regular maintenance.
With that being said, it’s your vehicle so go for it.

If you're using Amsoil there's really no need to use additional additives. It is one of the better synthetic oils and tests very well against wear and sludge build up.

I'm sure it's an entirely different product today, but the Rislone that I knew was something my stepdad used in the 70's if a motor was ticking or making other irregular noises. It seemed to work for that stuff way back then but I'm guessing it's not the same product.. And if it is, it's surely far obsolete for today's engines.

I'm still trying to put put together what a machinist is tearing down an engine, and it being 'clean' says about the protection this product may offer. That it was 'clean' is nice, but why was the engine being torn down? I'm not aware of a lot of cases where engines are disassembled unless there is something wrong with them, and if there is something wrong, then you would question what protection the oil actually offered right? You can put gasoline in the crankcase, and it will clean up all the sludge and buildup, but it really is not going to prevent wear very well.

I wasn't trying to be difficult with my question. If cleaning ability is what you're looking for, then all you really need is a good quality oil. I've torn down engines that are full of black crusty residue, and I've torn them down that are shockingly clean. I haven't seen a lot of rhyme or reason as to what promotes the residue, nor have I seen any direct evidence that it hurts anything. From what I've read, it seems that ester oil bases do a good job of keeping an engine clean. Assuming what I've read is true, the Amsoil you are using is a good choice. Others are Mobil1 and Redline (probably the highest ester content). I don't know what Rislone has in it. I doubt it can do much more, and I doubt it needs it.

He was modifying the engine to add power, that's why he tore it down. I think he said it had 60,000 miles and rislone was used from the start.

Exactly. I use the Signature Series way before they were called "Signature" oil in my diesels and gas engines except some of the German stuff and would not even consider an additive. There is as a point where adding a "good thing" becomes a bad thing because of how the products interact with each other. If the OP contacts Amsoil he will get a very specific recommendation.

This one had zinc and phosphors in it which are proven engine wear prevention additives but the zinc is bad for exhuast system components , one reason why ck4 oil is low zinc.
this one can not be found at large franchise auto parts auto supply stores. You need to check small mom and pop auto parts stores as this item is probally old stock.
