Oil Nerds Info

Jordo!

Why would I want to talk anyone into doing anything? I'm not selling anyone any oil

I'm trying to make a decision on oil based on objective data rather than anecdotes or theories about what should and should not work. Whatever decision criteria anyone else chooses to use is his business.

Also, I haven't ruled out Redline, I'm just not sold on it based on the information I've seen thus far.

What I'd like to do is try to match each oil's adiditive spec sheet to the results and see if there's an obvious pattern.

In keeping with this idea, some of the oils with the lowest wear ratings in that data set also have the highest concentration of molybdenum, which is added specifically for that purpose.

Also, allegedly, some of the oils favored by racing teams provide superior protection only with more frequent change intervals -- I need to do more research on that, but the implication is that for a DD, these oils may not be ideal.

Regarding your post -- yes, apparently some of the tests oil manufactures report findings for are more appropriate for testing gear lubes and greases rather than engine oils (alledgedly Amsoil is especially guilty of this) -- that's why I take independently gathered wear data from a highly similar engine more seriously than theories about the meaning of various spec sheets or oil classifications by themselves.

man unless your racing your car often i dont really believe you need to get this deep into oil..just change it often...if your looking for Moly just throw some of this into your oil..its excellent.

Thanks -- I'll look more into that. The only thing is whether it stays in suspension or winds up pooling at the bottom of the oil pan...

Mixed reviews on BITOG after a quick search... tough to find good oil analysis data

As to why I care -- the same reason everyone else does. You want to put oil in your baby that you trust to keep it together and running smoothly. I just like to make these decisons based on the best available data, that's all.

In the absence of wear data, you're left with with untested hypotheses about what an oil's spec sheet means and faith.

This is the "oil nerds" thread after all

Here's my plan. I did my first change already (early, at 1500 miles) with Nissan Ester oil. I'm going to do a Blackstone analysis done to make sure everything has been good so far. Then I'll do another analysis on my Redline after an additional 5k miles (or whatever Blackstone suggests). If Redline doesn't look like it's meeting or exceeding the protection provided by the Ester Oil, I'll try out RP, or maybe M1.

Trying to figure out what oil is perfect for me by looking at other people's results will leave me dizzy. Those drivers will have different motors, different driving habits, different roads, different intervals, different everything.

I definitely am in the same boat as you as far as wanting what's best for the car though, and I applaud you for it.

I understand what your saying but as previously stated by many here there is no "perfect" oil to meet everyones needs..everybody has different driving habits and weather to contend with..UOA's really mean nothing to us as those are specific to YOUR vehicle only..

Jordo!

Awesome! Yes, please post results when you have them! I'm curious to see how the Ester oil does too.

I may do the same after my first oil change, once all the break-in particles are flushed. On my third oil change I need to make a decision...

Right, but the degree of wear really shouldn't vary drastically for the same motor in the same car (i.e., in this case a sports car) even from region to region on a DD. If these were doing 24 hr enduro runs, sure -- but if the degree of, say, bearing wear varied THAT much, you'd see a lot more engines failing prematurely and mysteriously.

The exception would be people who spend equal or greater time on the track than the road, because we know that will have a huge impact on oil temps, which influences its wear protection.

However, that said, even given the fluctuations in oil temps, where the oil might provide less protection from wear, the ECU goes into limp mode to prevent that from happening.

Thus, I just don't think you're going to see wildly different wear results from DD to DD within the same mileage. the biggest differences will probably be in particles that indicate poor oil or air filtration.
