What positives / negatives can you tell me about this engine oil additive? Liqui Moly MOS2 Anti-friction engine treatment.

have a 2012 Jeep Cherokee with the 5.7 hemi engine that has a light tick on startup. The can says it is 300 ml; how much would be needed on a 7 quart oil change?

Thanks

IIRC LM has a product for hydraulic valves. That being said it just might be your choice of oil that's causing the tick.


oh..and Go Dawgs! They have an early game tomorrow vs Mizzou.

I tried buying their Molygen Motor Protect but they don't sell it in the US. I would have had to pay inflated Ebay prices and on top of that I'd need 2 bottles for my application. You can buy their oil with the Molygen already in it though, and for a decent price, on Amazon.

Get that water for oil out of that Hemi and put a good 5-10W30 in it and your tick will disappear... especially living in GA, cold starts aren't really a concern.

LM MoS2 will settle out of suspension as it’s not in a true liquid soluble form. I looked into it but decided against it after hearing advice from people far smarter and more knowledgeable on the subject.

Mobil 1 high mileage 10W-30. It is SN+ spec’d but without the GF-5 spec (meaning it’s not subject to the “resource conserving” fuel economy requirements). Should also keep seals pliable and from leaking.

Amsoil Signature Series 5W-20 or 5W-30. But honestly, that's almost like asking "what's the best oil brand". Everyone has got their favorite. You didn't say how many miles you had on it. But IMHO and speaking from a mechanic's (OCD aviation) viewpoint, a lifter bleeding down just wouldn't cause me any concern. Since you said it goes away on start-up. Now if it didn't, yeah that would bother me greatly. I certainly wouldn't use any "additives". I've never seen any engine teardowns where they benefitted from additives.

BITOG tradition is to use a different weight than what is specified in the owner's manual. Especially if you have a newer car that specs "water oil" lol.

Exactly. HTHS of 3.5 (“thick 30”) is the sweet spot for most applications in my opinion. Plenty of room for shearing and dilution to stay in grade.

Don't worry, a certain member will be along shortly to tell you that the cure for all your ills for the Hemi is Redline oil, because of high moly.

Down in Georgia, you should have no issues running a 10W30 year round, so go with Mobil if that's what you prefer. I stocked up on the Delo XLE 10W30 when WM was clearancing it, so that's what I would use in your case.

If your engine has MDS (I don't know all the intricacies of what had it and what didn't), the problem is one of metallurgy and can only be truly fixed by changing the cam out for a billet core instead of the SADI that was used by the factory, and replacing any damaged lifters as well.
