Here is my UOA from ~5.5K on Liquimoly Leichtlauf High Tech 5W40. Did a shorter interval this go around b/c mainly in-town/hard driving/sending it/drag racing as the COVID-19 [censored] has reduced my normal long daily highway commute; my normal OCI is ~7.5K. This change also included their MoS2 additive which can clearly be seen as the molybdenum and boron spike. Change before had Ceratec so interesting that you get a lot more of both moly and boron in that additive vs. the MoS2 (and you pay for it...it's triple the cost!). Also interesting is that I used Liquimoly's Proline engine flush so I pulled the sample before running that then pulled another after. Also of note, I have been using a "OH MY GOD K&N WILL DESTROY YOUR ENGINE AND INCREASE SILICON IN YOUR UOAS OH MY GOD" for the whole 35K miles and haven't cleaned it yet - will do per their recommendation at 50K which should be sometime next year.

Hard to believe one can have good UOAs with a K&N and not using budg-o-oils!

Do you feel the additives are needed? Or why run them? Not questioning validity of their use, just reasoning.

No, I don't. I just like to try things/test things is really all. I think the basic Leichtlauf High Tech 5W40 is more than sufficient but since I'm running software/hardware, I think running anything that can reduce friction can't hurt so more of a "why not?". A can of MoS2 is $7 and is good for a single change. A can of Ceratec is $23 but lasts 30K miles per LM. The newer Molygen oil has additive in it and is the same price as LLHT.

Yep you will definitely see HP/wear improvements on modified cars with friction modified and/or high end ester/AN type oils. Nearly everything on this site has been made relative to standard cars. What's the best cheap oil? What's the best cheap filter? etc. And that is fine but once you start down the modification trail, the specialist and high end oils & some additives etc make a real difference. It's why they were made. So, who is putting Redline in their stock toyota, ford etc I know you are out there...

Amen. Happy with my Liquimoly and additives so far. But if Wallyworld/Amazon/Costco brand are you jam (buying in bulk/hoarding of course), whatever floats your boat. This site seems to have turned into "Bob is the budg-o oil guy!".

Wear metals are very good. One thing about the vast majority of 0w40 and 5w40 PCMO's is they all lose their viscosity quite easily and rarely stay in grade. However, it didn't matter in your case as wear remained low.

Interesting - I did not know that. If you look at my viscosity data, looks like 5K is as long as you can go without it dropping to 30w and could give some weight to the 5K OCI many use. But as you point out, I don't see that this is causing issues.

I agree. Your wear metals are good. Most of the larger spread oils (0w40/5w40's) are going to drop a grade unless they are using as little VII's as possible or very high quality VII's which are expensive.
