What oil "clings" best to an infrequently run engine?

[Revving2Redline]

Redline 5w30 maybe?
I would run a fuel additive like Royal Purple Max Clean which has pea and can be used as a fuel stabilizer also with some non ethanol fuel. Drive it around 20 minutes to get it thoroughly cycled.

STP oil treatment will do what you want. I use it when building motors as pre-lube on bearings, cam, etc.

Doesn’t matter. That’s not how oil works.

Your antiwear - ZDDP, Moly, etc - form a bonded plating layer on the inside of your engine, where the oil touches. The antiwear wear requires the oil to be at 160-180f to re-bond to the metal.

So on start up, you have the antiwear plating there. Run to operating temperature, and it refreshes.

The more oil “clings” means you’re going to have slower pumping on start up. But that’s an entirely different thread.

I think your truck would be much better off just starting the car every month or two than relying on some supposedly superior motor oil.

This ^^^
Let it warm fully to operating temps - better yet, drive it some …

Definitely give Triax lubricants a try they have the additives needed to cling in your engine.

What chemistry component in the additive package would accomplish this?

Rust inside of an engine, even with infrequent starts, is a non-issue.

Well, that might be your experience but it's not everybodys. Especially in humid rainy climates, moisture in the air gets in even into an engine. If I had to leave my car sitting long term (over 6 months or a year) I might pickle the engine. This means filling it with oil until it can literally hold no more, leaving everything soaked in oil.

Sounds like a legit use for slick 50. Find the formula from the commercial with the treated engine running without oil.

kind of a interesting concept that may work, though you may not attempt to start the engine ever when full like this, other thought is how does the military store engines when in standby/storage , fogging oil mist ?,,,if lesser time for safely storage times ,its best still to just run engine up to temp every thirty days or so with clean multi viscosity synthetic oil in them of your choice, driving the vehicle is best as to circulate the tranny and other fluids as well, and keep a eye on the fluid levels fresh gasoline with a stabilizer , tires etc. adding other engine additives may cause more harm than good ? or be ineffective unless designed for this situation.

Suggesting to run Triax is like the following….

OP, This is what Castrol Magnatec was designed for.

HPL PCMO and HDMO aces the more advanced rust prevention test of 24 hours in saltwater. (API test is just 4 hours in freshwater)

Amsoil Z-Rod and Driven GP-1 are also formulated with long-term rust prevention in mind.

No oil supplement is going to match their performance. If your oil needs a supplement, you're using the wrong oil.

Would it be smart to add a tube of assembly lube to the oil?

I think the whole point of assembly lube is that it clings...

Both the Black and Gold Edge offer better and longer protection than discontinued Magnatec once did.

 

[Triple_Se7en]

I was thinking the same thing. Might be the 2nd use for that (STP) stuff.

What do you consider the 1st use for STP Oil Treatment?

 

[Foxtrot08]

Filler for the used oil tank at the shop.

Uh no. Assembly lube is there to protect a freshly (re)built engine for initial start up, until oil actually gets to the engine. Since there is, no oil in the engine at all.

Dumping assembly lubricant into your engine after start up is a great way to clog up oil valleys and filters. Probably doing damage.

STP Oil Treatment has been on stores shelves since 1954. That's 70 years of success.
So if you want to brand the product a failure, then please move from my barking tree to another member's tree.

I support the product - about once every five years. Judging by continuing sales, so do millions of Americans.

Where did I say it’s a failure?

Pointless, yes. Not a failure. Lucas makes enough money off junk oil additives that they admit, are not for fully formulated products, that they can brand a football stadium.

That’s pretty much not a failure. Making money, means it’s not a failure.

But, a lot of pointless things make money. Two different things.

Right. Sort of like all those people paying money for Bruce Springsteen tickets.

I couldn't care less how long it's been on the store shelves. It just means they've been scamming people with clever marketing tactics for 70 years. Least we forget, STP got slapped by the FTC for false advertising and had to pay over $800k in fines, but what's $800k when you profited several million a year? They could sell that bottle for $1 and would still be almost all profit. There's nothing in STP Oil Treatment that will improve rust prevention. It contains barely a trace of any additive at all, much less anything that'll prevent rust/corrosion or oxidation. It's just going to dilute what beneficial additives are already in your oil.
