Any harm is using Maxlife blend 5w30 and Liqui Moly Oil life extender for one full OCI to help an oil pan/rear main seep on an LS1?
Do you know what type of oil pan gasket it is? If it's leaking from the rear main seal for example, Mobil 1 EP HM will do a much better job. It helped swell up shrinking seals on our 2017 Hyundai Santa Fe 3.3GDI engine, specifically the CVVT seals. Once I started using Mobil 1 EP HM 5W-30, the startup rattle stop. Before oil was seeping past the CVVT seals back ton the pan, causing the CVVTs to rattle every morning. So, if you have a seepage issue, with internal or external seals, Liqui Moly won't help. I never tried Valvoline Maxlife, but Mobil 1 EP HM worked well for my situation, so I kept using it.Have some small sweat marks I am trying to squash without pan removal (not easy task on 98-02 V8 Fbodys) - So I was going to do the HM oil + LMOS for this OCI and then see how things shake out.
ThisThe only time you use an oil additive is when you're 100% sure that something is missing from the oil you want to use in your engine.
Here's an example for you: You want to use an Euro Oil like Castrol EDGE Euro 5W-40, however, you want more seal conditioner in it. However, you don't want to compromise the additive package of the oil, especially the anti wear and detergents & dispersants. You add Lubegard Bio-Tech at 3oz. per quart of oil used. It might still produce unpredictable results that you'll never be able to measure. Bio-Tech has a small amount of safe to use seal sweller in it, along with MoDDP (instead of ZDDP), and Calcium Carbamate, so it's pretty basic. It will however, displace the additive package by a certain percentage found in the oil you're using.
Now, is there something in Liqui Moly Oil life extender that your engine needs absolutely to have? Otherwise, there is absolutely no reason to experiment with it.
You'd be better of to just use a higher quality motor oil like Mobil 1 EP High Mileage 5W-30. It's blended from high quality base stocks, and has a very good additive package. It works very well.
The LM product is similar to others in that it contains an ester to encourage some seal swell. They are not one-time use but part of a regimen (20k miles). You obtain similar results by buying a HM oil.Any harm is using Maxlife blend 5w30 and Liqui Moly Oil life extender for one full OCI to help an oil pan/rear main seep on an LS1?

LM products do no harm. So there's no worry about using it if you're looking to use up some MaxLife oil you have around.
Your results will be solely depend on the current condition of your seals and their material.
Non-HM oils are designed to be compatible with seals but that's not what we're discussing.
The LM product is every 20k miles with around 500 miles to notice results. As for your chosen grade I would go by your owners manual which I presume is 5w30.Thanks!
I change the oil once a year before storage, and do around 6000KM a year (4000Mi) - Would it be OK to do my yearly Max life blend 5w30 and filter change, and toss a bottle of the LM oil saver in every change assuming it gives me good results this time around?
Ya 5w30 - I was more wondering due to the long sit times over winter storage and not using the car, would there be any harm is using the LM product every oil change along with my HM oil?The LM product is every 20k miles with around 500 miles to notice results.

Done already.LS is a one-piece pan gasket. Why not try checking the torque of all the pan bolts first before possibly missing the root cause of the possible weep? Those gaskets have metal inserts to prevent over-torquing, so there is literally zero risk to climb under there and snug them to the proper torque.
So I shouldn't run this WITH maxlife?I've had good luck with Oil Saver, but as said previously run one at a time. Do the HM, then run the LMOS with whatever non-HM you have on hand. It might take two OCI's before you really know if seal conditioning will help...
Liqui Moly Oil Saver is up to 10% ethylene glycol monobutyl ether acetate, the rest is group III base oil. Don't mix it with any High Mileage Oil, unless you want to create a new problem. It's basically a seal sweller.So I shouldn't run this WITH maxlife?

I would not use it every oil change as it's going against the instructions from LM. I wasn't aware that MaxLife product is also a HM oil. Meh. You may want to contact LM to see if it's okay to use rather than rely on unqualified opinions here.Ya 5w30 - I was more wondering due to the long sit times over winter storage and not using the car, would there be any harm is using the LM product every oil change along with my HM oil?
