Hes giving very specific advice with precise instructions. What is so hard to understand about this?

Mac, I do amit this is one of the funniest things I have seen posted.

I changed the oil with DT40, so we'll see what if anything changes after another 4k miles.

One thing to note: halfway through the last interval, I had a leaking drain plug, so I drained the oil into a clean bucket and refilled from there. So it's certainly possible that there was a bit of contamination--we are talking about parts per million here.

FWIW, no track time, but this is my daily driver, so plenty of stop start.

i have 200,000 mi of experience using delvac1 5w40 in gas VW's and an equal amount with diesel vw's with long term UOA. it has been my goto oil, sadly getting Joe gibb oil up here in the wild north is a pipe dream i'm still trying to find a supplier who will bring it in and not charge $200 a case. the boxster currently has delvac1 5w40 in the sump but it got trapped by winter and so we pull a sample soon to see

"Blind faith" is the phrase we use to call buying/using a product off un-posted R&D. Last I checked, "sheep" was a much more accurate description of said group.

Quite frankly, I don't understand your un-checked enthusiasm for a product with exactly 1 professional recommendation (Raby). And going by the publicly available marketing descriptions, I find absolutely nothing that screams "better" to me than any other oil. Correction, considering the complete lack of technical data available, I don't even find a basis of comparison. Could be great stuff, but hell if I know.

So given that, again, I'm a little confused about your holier-than-all stance toward this oil.

Personally, I find the information vacuum surrounding the stuff a little odd; the quickest way to selling a product is openness in form and function with your target market. And when the people come knocking requesting information about it, I wouldn't tell them they wouldn't understand even if it was provided..

Note: I have the IMSB (on Raby's research), as well as the 160oF thermostat among other things (in agreement with many of Jake's positions), so this is certainly not calling into question his expertise. It's simply that for some of us, we'd rather not the "black box" model of car modifications and maintenance.

Don't bring logic into this infomercial...

Let's not let this go ugly personal everyone. Jake is good, in fact, very good, and if you don't like his prices or methods, well...welcome to America. He has done more towards helping us understand and addressing the M96 foibles than anyone in the US I know of. The fact that Hartech also came to the same/similar conclusions lends a lot.

My only point was not to let this become the scene from "The Jerk", when Steve Martin is getting shot at, while working at the gas station, and the bullets are hitting the oil cans. "What's wrong the cans? He HATES the cans! He's shooting the cans!" I laughed my butt off at that (one) scene. True classic.

Jake says he's got tons of oil tests on the DT40, and it is better than Mobil 1 & the other oils he's tested. The viscosity is good, and it has plenty of zinc. I'm sure it is a great oil. Do you think he would base his entire business and personal reputation on it if it wasn't? But to summarily assume that all other oils are no good is crazy. IMHO, it's just as crazy as letting an $80k car go 10k+ miles between oil changes, because $120 is too much to spend on the most important preventative maintenance on an engine known to have the possibility of lubrication issues. When I changed out the oil cooler o-rings, I tossed the whole crankcase of Syntec 5w-40 oil with well less than 2k miles on it, just on the possibility that some coolant might have splashed in to the oil ports. 99% sure it was fine, and I took great lengths to prevent it, but I wasn't taking a chance for a lousy $100. (I really don't understand the cross contamination comment though. Macster hit the nail on the head. You can, in no way, get all the oil out of these engines in an oil change. When I dropped my pan, there was a ton of oil still dripping out after a week. At least 8oz. Why would you use break in oil on all ready well broken in engines. Do a short term flush with DT40, and then another right after, if you want the cleanest purest DT40 in the engine. Other synthetics have no problem with other oils, so why would DT40? Dilution is the solution, as we used to say. )

Bashing helps no one or further our learning.

Jake, I bought a case of the DT40 from you back in Sept/Oct and again another case from Charles in November. I wish I was told about this "flushing" step. I never was.

Regardless, I am very interested to see my future Blackstone reports from your oil vs. my previous selections of M1 5W50 and Red Line 5W40.

Thanks.

perryinva

ME too! Please post them, or PM me to let me see a copy! Thanks!

LexVan

OK, I will. Car is in hibernation till spring. I'll post UOA's this coming summer.

The oil flush is recommended when swapping between any two oils that are based from radically different base oils and anti-wear/ detergency package ratios. This is really only important if you wish to ensure your first UOA after swapping "systems" won't come out with weird results from cross pollination.

We do this with any oil, not just DT40 or other Gibbs products.

That said, classic oil thread, so Raby is out. If you want to only used an approved oil, thats fine. If you aren't closed minded, then follow me. Its just that simple and it doesn't matter to me one bit.

Ubermensch

With all due respect, why would not following your recommendation indicate someone is close minded? To the contrary, people are asking for more information (indicating open minds).

Flat6 Innovations

This is the internet. People ask for more information as a basis for further argument. This has not changed since 1995 in my experience. Thats why I never participate in these threads, and why I should have never posted in this one.

As more people use the product the UOAs gathered from independent sources will be posted. As people are more pleased with the performance of their engine, MPG and start up noise/ etc the product will gain a reputation and respect. Until then no one can catalyze the process, certainly not someone thats biased like me. Porsche owners are a discerning group and products take years to gain a reputation. I started building mine in 1992 in this industry and I understand the process better than anyone.

All I care about are my engines and they use DT40, just like they use all the components that we have developed. When people come to me for a solution to their problem they WANT to use what we know works with our internal modifications and whats been developed alongside the rest of the engine. They don't have to be convinced. Until another engine developer in this game develops their own oil with a company like Gibbs and Lubrizol, we'll maintain our advantage. Lubrizol invented ZDDP.

I am already working on a DT40 variant for the 9a1 based engine and its used in my 4.2L beast in Cayman X. Either people appreciate what we create and want to share it with us, or they don't. Last time I checked this country was still free and at least for now we don't have to buy oil from the government.

Gonzo911

Seriously? I would guess a very few of us would even know about your new oil product if it weren't for the threads posted over the last few days.

I would guess that very few of us would know about the IMSG, IMSB, or the IMS Solution if it weren't for threads like these.

I don't mind you marketing your products in the manner you do. As a matter of fact, I think it's brilliant. Just lose the attitude.

KrazyK

You should be thanking the man not second guessing and insulting him. Since he was the brain behind the IMSB retrofit when Porsche said it couldnt be done, all the Porsche sheep need to remove the new retrofit IMSB and bring your 996 to Porsche for a new shaft with bearing install.

To those that keep re-hashing what he recommends: You have got to be out of your mind. He is posting FREE info that none of us have the ability or facility to research ourselves.

My favorite quote from JR:

Agree x1000

Sneaky Pete

Well.....like ALL oil threads this one was a waste.....now for something completely different.

Just substitute the O word for the S word.
