He's doing 8000 mile assessment intervals, not change intervals.

uh huh...

when did i ever say they were changing it @ 8000?

From the literature it sounds like there is 8000 test miles to this point.

So after 8000 miles you have determined it is the best **** ever? Again, I'm sold. 8,000 miles is a lot.

edit: oh, my bad 17,000. That's almost as much as an oil company or auto mfgr would do, probably. BEST OIL EVAR!

Ah. Just call Ray and tell him how much you want.
BHR isn't the world's most savvy Internet-based biz. That's not really the focus.

Oh, I see what you mean.
No, I don't think that's his point.
There was just some concern that this stuff was bad for "yellow metals" in the transmission.
The assessment is just to judge whether or not that was the case, which it has turned out that it wasn't.

As far as what's the "BEST OIL EVAR!", I think you would just have to either decide that for yourself or go with consensus.
I'd probably suggest the former, since there really isn't much of a consensus on the other choices, just a lot of adamant users.

I've used Redline 75/90, MT-90, MTL, mixes of the two, Ultralight, light and heavy versions of the shockproof as well as Penzoil, Mobil 1 and Royal Purple.
The Eneos gives the best shift quality and eliminates high RPM misshifts (other than the dumb-foot induced incidences).

It seems like literacy is in short supplies these days.

The purpose of the testing was to see whether or not the Eneos was hazardous to yellow metals in the RX8 transmission. If after 17,000 miles of daily driving including during the summer there's no issues then I see no point in further testing. Since I have no baseline for my own transmission regarding wear and I started the testing with approx 75,000 miles on the car it's pointless to continue.

Blackstone's report suggested another 8,000 miles on this oil. I trust their judgement so I see no reason why someone couldn't get 30,000 miles on a single interval.

In terms of my opinion regarding the shift feel I used RP, Mobile1, and every single transmission fluid product in Redline's lineup. I like the Eneos the best.

oh, my bad 17,000. That's almost as much as an oil company or auto mfgr would do, probably. BEST OIL EVAR!


You're free to offer up your own testing at any time. However, since you've not provided a single item of any relevance on this forum aside from drive by shooting threads you'll excuse me if I don't hold my breath.

Assuming that was the only intended purchase then you might have a point but yeah, I can go elsewhere for satisfaction, no problemo ...

It's just funny the amount of effort that has been put into hyping this one brand of oil.

I'm not real sure who you think you are impressing by analyzing oil for 17,000 miles that has probably had a few hundred thousand, if not a million dollars of chemistry, research and development thrown at it before being put out on the market. The point is who gives a **** about 17,000 miles? It's so trivial and insignifigant that it's a complete waste of everyone's time.

There are several very good reasons why you and your crew know nothing of what I am up to. There are a few around here that know and a couple who have helped in various forms. You have nothing to contribute so you haven't been aprized of the situation. If there becomes a point when it becomes public then I will provide all the testing results necessary. But I can assure you I'm not throwing money at "researching" someone else product.

I think you are trying to mix an appraisal of the product with an appraisal of its use in this particular application and the desire to have a sense of security about it.
There had been a worry that this oil was not a good choice and the analysis was just intended to illuminate the concerns since, from a utilization standpoint, the stuff is really good.

I don't think anyone was trying to "chemically" prove the "superiority" of the Eneos gear oil. Just its compatibility.

You are amazing, Kyle. With radiators, you demanded temp delta data that NOBODY in the thermal industry provides (and for good reason) and with tranny fluid you don't appreciate the fact that BHR hired a third, and objective, party (one who specializes in these things) to evaluate a specific fluid for use with a specific transmission. At our own expense.

In one case you are asking, nay DEMANDING, we provide data and in another you are discarding the fact that we do.
two completely different scenarios.

you put out a radiator that was completely new to the market. you put out a radiator that doesn't work. and claimed it was the best thing ever. it doesn't do the job it is intended to do any better than any other radiator out there on the market. and it's not cheap either. i wanted to know what you saw that made you think it would be a good idea to add more capacity to the trans cooler that I had already looked at temperature data for and knew for a fact did not need the capacity. That extra capacity should have been used for the water cooling because that is where people are having the problems. The car I put that radiator in I cant get the trans up to temperature below 40*F for half an hour of driving. Fact. Wonder if that had anything to do with the rebuild?

Now in comparison why would I care about 17,000 miles of data on a product that probably has a million or more miles on it from the mfgr? They already stated GL4 spec safe.

There is an enormous difference in these 2 things.

When I see mistakes, I try to correct them.
It's quite a different thing than trying to address outwardly manipulative behavior.

I am, by nature, an excessively accommodating individual.
I just don't extend the same level of accommodation to willful ignorance, which is not what you seemed to be conveying in your misunderstanding of the direction the oil analysis.

A good look

All cars made today have brass syncros that look the same as RX8 syncros. To think that the oil companies would make a product that would destroy every gearbox it went into is rediculous. When I first heard this GL-4/GL-5 corrosion thing, I did some research on the oil co web sites. I couldn't find anywhere that said it was harmful, so I sent a tech message to the Amsoil tech guy. His response stated the history of how that myth got started by the ignorant VW people. When GL-5 first came out it was indeed corrosive to brass syncros. But only at temps above 250ºF. Now since it is impossible to get any street driven gear oil to that temp (It is hard to get engine oil that hot!), there will be no problems using regular GL-5. However, just to satisfy the ignorant masses, the API came up with another added rating, called MT-1 which is tacked onto the end of all GL-5 oils you can buy today. With this MT-1, GL-5 oil is not corrosive at any temp.
The difference between GL-4 and GL-5 is the extreme pressure capability. On surfaces that have high pressure where metal to metal contact will happen, the GL-5 is way better at protecting. Spider gear teeth and side gear teeth are one place where GL-5's better EP rating is desperatly needed. I've got 5-6 Bus 091 ZFs in my garage right now that have suffered significant wear on the gear teeth from probably using GL-4.

If anyone has questions regarding the Eneos GL5 feel free to use my email address. I've grown tired of addressing concerns of individuals who are interested in nothing more than being critical of products for the sake of doing so without providing anything of substance and have no plans on becoming a BHR customer.

You need to get your facts straight then. On a personal level maybe, but you overlooked what I do for a living. The satisfaction level of my own transactions and capabilities speaks for itself as well.

That said, I have no doubt about your costs/profits. I already knew about the suitability of certain GL5 oils, so that was nothing new to me either.

I drive by the local Summit Racing store daily so picking up some $8/qt Redline oil is no biggie. Thanks just the same.

i hope you won't quit posting in general because I benefit from seeing what you have to share.

Each forum has its character and this one is the bitchiest I have seen. Really good, smart people fighting each other. it really detracts. I stay here because of the good stuff people share; we should all quit lashing out.

I hope at some point I can contribute too. Right now I am still pretty new to the RX-8 and still learning.

No I certainly won't stop contributing information. The whole focus is to provide the information to the community and then let everyone else decide what they do with it.

In this specific instance, I won't argue with individuals that are doing it for the limited purpose of doing just that...arguing. When the focus is on arriving at a solution to a problem or brain storming on methods to solve problems I'll always be interested in that dialog.

The nonsense here is just static and should be treated as such.

Theres almost no advice on this. Cant get anything locally that isnt gl5 or 4/5 but i found pennzoil saying it was good for yellow metals. I found 1 or 2 references to people who used it and that was it. Its full synth for 8 a quart but im not sure im ok with it.
