Break-in is real - it is quite severe in the S2000, with performance gains noticeably and measurably increasing as the miles pour on. Mine only has 1800 and is still tight. I have found increased peformance in every car I have owned that was bought new. I have calibrated test equipment verifying those increases, and track times whichh reflect them.
As a tribologist and ME, I could explain what is going on physically at the nanotribologic level, but it would make some folks' "heads hurt", according to their own posts on this forum. The short version is that ring tension and asperities on the cylinder walls need to hone to reduce friction and the resulting parasitic power loss. This occurs to a lesser extent throughtout the powertrain, including the ring/pinion or transaxle gears.

RP has not been around very long, and its ad copy reads like a marketing man gone berserk, rather than a sober engineering oriented company. I do not know any of my friends who are tribs or SAE members who use it.
On their site last year, I found a huge "oversight" - they were hawking one of their non-synoils as a synoil - it was eventually "corrected", but no banner headline to clarify for those who had already bought into it - they probably still do not know.
I think any oil company that has to get a trade or service mark for its purple bottle has issues.

It may actually be deeper than just the mechanical effects - there may actually be CHEMICAL changes at the molecular lever, as the following paper postulates.

i'm still curious about the oil additives. from what i can gather, the shear psi of the oil must hold up to the ring pressure which in concert provide the seal and lubrication. if the oil cannot "cling" to the cylinder wall surface there may be metal-to-metal contact, which is bad.
i'm still curious to know the relevant power gains would achieves by having a cylinder wall that, on the molecular level, is flatter.

Not necessarily "flatter". Actually the atoms rearange themselves into a configuration that is more conducive to less friction. Thus, the breakin occurs and the result is performance improvement that Road Rage has clear documentation of.

Yes, Group II and group III oils are kick ass. This will be the oils of the future for sure and a lot will be made right around the corner.

that doc is a study of wear as examined as plastic deformation as matter migrates out of the friction zone. the amount of reduced friction lends to more power on a scale that is probably undetectable on todays dyno machines. the doc also clearly defines a wear rate, so my guess is, if a additive creates a layer then at some point that layer of composition must be worn away (the doc says the thinner layers have lower wear rates, so i'm hoping the oil additive creates a very special very thin layer).
270.125679 HP with additive
270.000001HP without additive
and before you jump, these #'s are bogus, i'm just making my viewpoint.

Took car in today for first oil change and requested Mobil 1 (6100 miles). Service advisor told me to wait until the second oil change or at least 10,000 miles to put in synthetic because it takes that long for the rings to completely seat. He'd had an integra with first oil change with synthetic and it began using a lot of oil. Any thoughts?

Today's boring and low ring tensions do not require that much break-in. Plus,. the best mineral oils are just as low in friction as the synoils, so there is effectively no significant spread there.

I suppose it really boils down to what you are willing to spend and how you feel about your engine.

Yes, i read it a few years ago. Of course, a test mock-up in a lab does not translate to real-world conditions.
Note that the article said "treadmill". That should tell you the technical expertise of the reporter - it really is an odd article anyway, as there is no comment from others (hell, i could have commented) to question or make salient comments about the applicability of the tests. The whole thing read like an info-mercial for "shark cartilage"; the kind you see early in the a.m. on cable TV.
Highway driving, even at speed, is the least stressful of all drivijng, since the loading on the engine and tranny are minimal.
I do not dispute Mobil1's test, and they make a fine product, no doubt. But I would be more interested if it would involve M1 and one of today's best minoils, lke MC or Havoline.

Seach these two terms:
"PCX-004"
"PLM-A01"
You will get several good and 1 or 2 VERY GOOD oil filter threads.

Okay i am gonna use Mobil 1 synthetic oil on my next oil change, the manual it recommends 5w-20 on regular oil. If im using Mobil 1 synthetic should i use the same weight????

5W20 or 5W30 should do you fine. Either one.

Earlier in this thread different weights of M1 were listed along with their "recommended usage". But, the stock 5W-20 wasn't included.

Oil is such a controversial topic, but there are some "truths" that should be considered. 20 weight oil seems to offer slightly (maybe one, if not less, miles per gallon) due to it being thinner which results in less resistance in the internals of your engine. The down side is that some will say it offers less protection in the long run compared to a 30 weight oil. If you read around, you'll see a lot of car manufacturers switched from recommending a 30 weight oil to a 20 weight even when the engine remained the same. As to why this was done, who knows but there is strong evidence supporting the EPA really pushing car manufacturers to be more "green". Personally, I choose to run the 30 weight (Mobile 1 or Amsoil 5W-30 Full Synthetic to be exact).

If you look back over the years, manufacturers used to have a wide range of acceptable oil weights in the owner's manual based on the climate the car was going to be run in. Some ranged as much as a 5-30 for very cold climates all the way to a 20-50 in very hot climates. They left it up to the consumer to make the right choice. As the average car owner has become dumbed down and the CAFE and EPA are really pushing mileage, they have gone to the one oil fits all thinking to avoid problems. I know GM had problems with owners using 20-50 in -30 degree climates and spinning bearings.
Oil choice should still be based on climate and operating conditions. If you live in a cold climate or do only short trips where the oil never gets to operating temp, go for the 5-20. Hot climates and hard driving, a 10-30 will work nicely. I guarantee the 10-30 is no thicker in a 100 degree summer than a 5-20 is in a cooler climate.
Out of curiosity, has anyone ever seen the recommended temp ranges for different oils? Even a 10-30 is plenty thin for sub freezing temps. That's why I run the straight 30wt in the hot summers around here. In the Vegas summer I would have no problems running a 15-40 in the TL if I planned on running it hard at an auto-x. Again, super hard long runs in 110 degree heat, the 15-40 is about as thick as a 10-30 in normal conditions.
In other words, just use your head.
Cold climates, short trips= thin stuff.
Hot summers, hard running, long trips= thicker stuff.

Just looked it up. A synthetic 10-30 is ok to use down to 0F. I'm not sure why these 0 weights are so popular.

I doubt there is any significant difference between 20 and 30 weight oils for a basically stock motor and normal street driving. Anyway, back to the original topic of the thread. I think Mobile 1 is a great choice and readily available. I've always been an Amsoil fan but they didn't have the weight I needed at Joes.
