RS-R Ran-Up Engine Oil Treatment
 

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.

Among the claims that it produces more power (which isn't hard to believe if you understand how oil works), I read many reviews at how the engine became quieter after using it. Since RS-R is a reputable company (i still remember how bad *** my SR20 sounded with an RS-R Exmag exhaust) I decided for $50 it was certainly worth a shot.

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.

Snake oil







IMHO

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

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.

did you even bother to listen to the video I posted?

I have 600hp, if i care'd enough about the potential for an extra 10-15hp, I would have. I was more concerned with the engine noise.

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 it worked for me I see no reason it wont work for you, my engine is particularly loud though, so the difference may not be quite as drastic.

just to be clear, I have no affiliation with RS-R, and they didn't pay me to post this, I was just so ******* excited about the difference I thought others would be too

Thanks for the heads up! Will try this out with my next oil change

That before sounds like you have an F 350 idling next to the z. Sounds like a pretty dramatic change though.

Why are you running 10-40 when the mfg states 5-30 http://www.gixxer.com/forums/images/.../confused1.gif

A lot of people, especially TT people use 10W-40


My issue is, why does the OP think 0W-20 is ok to run now???
EDIT: I guess you only use 300mL of this in an oil change?

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 ASSHÒLES 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"

correct, the 10w40 was for summer temps with a twin turbo car. I originally ran 5w30 at my first oil change to sythentic. As for the weight of this additive, its a very small amount going in.

I will be giving the ester oil a try as well, I did consider it but my valvetrain chatter seems to be quite unique. Plenty of people (including myself before the build) ran other oil with no noise issues. I suspect that my VVEL did not like the engine break in oils used.

Try NISSAN's Ester oil, not just Ester based
