Yes. Have for years.

 

[Backrd.Junkyard]

Yes. All the help I can get with flat tappets.

Why not just use oil with the proper amount in it to begin with?

 

[plymouth67]

I have used it before. Never had any issues.

had to change the oil and they didnt have crap here.

I use Engine Oil Supplement (EOS) from GM parts department.

I use it. Can't tell if it works or not. I consider cheap insurance, peace of mind.

 

[Backrd.Junkyard]

That's it. A little extra peace of mind with the ever declining amount of zinc in oil. But also within reason, as too much of a good thing can lead to combustion and exhaust deposits. But I'm pretty archaic with oil selection, preferring Rotella T1 SAE 30 and liberal warm up time. But I'll be running SAE 30W VR-1 with minimal additives after going with a solid flat tappet.

Well to cover the deposits, I run Seafoam in the fuel. I'm a hook line and sinker nut when it comes to car maintenance lol.

 

[383man]

Yes I have used it for years also. Ron

Well......it looks like the Rislone does what it claims by adding zinc and phosphorus, but this guy says it's not good.

I was just about to post that video.

More Zinc more wear.

The guy's a dork but if you believe what he is saying you shouldn't use additives. I would need to watch it again but did he analyze the hot rod oil like Joe Gibbs and the like. That stuff is just base oil with additives.

 

[RemCharger]

Lots of stuff to start debate in the video but my question is; do you think he is biased.

 

[moparedtn]

Same old story - additives like zddp are best applied if they're part of the formulation of the oil to begin with.

 

[eldubb440]

tell everyone they have oil problems and get plenty of views

 

[Billccm]

I think he is showing that the Rislone is adding zinc and phosphorus as the product claims. Can't see all the parameters, but he didn't say the Rislone is impacting viscosity. I consider this good information.

Looking at this objectively, nothing is too big of a surprise. Marvel mystery oil is a great product, but it's not really intended to be a oil additive at every change. It's to clean a neglected motor or reviving a motor from an extended slumber.

Same for Seafoam. It's a great product in the crankcase maybe once in the motor's entire life to remove sludge. Seafoam is actually intended to be a fuel treatment as it's primary purpose.

I would have summarized the results differently. My results would have been viscosity impacted, chemical change, and good verses bad for modern and classic cars.

Finally, he said something about impacted wear after 2800 miles, but that was speculation which he claims not to do?

Maybe. He added the zddp to a plain base oil. The theory has been that it needs to be formulated, but just pouring the additive in and using a mixer showed the oil increase in zddp. Furthermore, the small additive amount ratio worked as expected with zddp levels.
