So after I built my engine my car was VERY quiet, people commented on how quiet my engine was and all was right with the world. After the break in period around 3,000 miles I switched to synthetic oil and my engine sounded like a direct injected diesel, loud and obnoxious, everything was ruined. I've been pretty bummed about this for awhile so I tried switching oil, first I tried mobile 1 10w-40, then redline 10w-40, no noticeable reduction in noise (though redline actually ran a few degrees cooler in summer heat).
10k miles later and the car is running great but the engine is still loud, and I ran across this article on RS-R's Ran-Up oil treatment. Quote:
![]() I decided to take a before and after video, and boy am I glad I did. This stuff works amazingly well, listen for yourself. This was taken the same day, the oil was recently changed (10w-40), the engine was fully warmed up in the before/after videos. All I did was drive the recommended 30 miles after adding the oil treatment, thats it. I haven't driven it much beyond the initial mileage so I will update this thread with further impressions but as of right now I plan on adding this with every oil change (only about 2-3 a year as this is not my daily driver). Note: I have no affiliation with RS-R and they didn't pay me to post this, I was just so fcuking excited about the drastic reduction in noise and i wanted to share my results with the community.

It's hard to argue with success. If esfourteen were not a long-time member (Join Date: Mar 2010, Posts: 1,156), I'd be inclined to agree with you. A quick glance at some of his previous posts leads me to accept his claim (reduces engine noise) even if I still have my doubts about reduced friction. I'm sub'd to see long-term results.

That's Crazy and a Solid Gain in reducing the noise, Props OP Great Review! Would this work on N/A just incase you start getting this question soon?

If you like it you should put a dyno on it.

OP, did you ever use Nissan's Ester oil?
I ask because Nissan's ester oil has a very high amount of molybdenum in it, which is a metal lubricant. And it's recommended to lower valve chatter in our cars. Combine Mo with 0W-20, presto chango, extra HP, and a quieter motor... All at the expense of, well... $50... It could also be boric acid added to the oil, and whenever these ASSH̉LES write "nano" anything, they write that JUST to sound cool, never believe the claims for what's in the bottle when you see them advertising "nano"

This thread has got me overly intrigued...
I'll call them up and see if they want to dyno my car, I'm local-ish... Let them do 10 runs pre and post? There's a post that someone with an NSX tried it out, and it worked well... I really want to see what an oil analysis would reveal. Looking at the bottle again, it doesn't say that it is safe for catalytic converters, so maybe it's ZDDP, making it essentially fancy break in oil.

And we have a winner. NASA has used MoS2 and PFPE in space (damn you NASA for being down, that was a tad harder to find)
MoS2 - Molybdenum disulfide PFPE - too long to write, it's a sister to PTFE (designed as a liquid form of PTFE) PTFE - Teflon, novel idea, but it's old school Slick50, works, but Teflon builds up and can cause blockage of oil passages in small areas. All that being said, you'd still need an oil analysis to see if it's MoS2, PFPE, or ZDDP, or a mix of them
