I use it....

....and the sale price wasn't any better than the price on Amazon.

I've done three oil changes with the DT40 since I got the car back from Jake and Flat 6 Innovations where they fitted the "IMS Solution".

As part of the deal, I agree to only use DT40.

Fine with me, not really any more expensive than Motul 8100.

Oil is cheap, engines are expensive.

After a 5,000 mile trip to Colorado and back from my Louisiana home in my 2004 SE, she only dropped one quart. And that was crossing multiple 10,000 foot passes and lots of hard throttle under load at altitude.

One nice thing about the DT40, which you should change every 3,000, by the way, is that you can hear when you need to change the oil. When the oil is fresh and clean, the lifters and cam chain tensioners are quiet on cold start. When you hit 4,000 miles on the oil, you will hear "Click & Clack, the Tappet Brothers" while they pump up.

That's a friendly reminder to change the oil.

My old 1993 Miata was the same way, I knew when it was time to change the oil because I could hear the lifters pump up on startup.

My magnetic plug has been spotless so far. Again, three changes, and 13,500 miles since the IMS Solution install and the other items I had R&R'd while Jake was in there.

I don't think that is a good selling point, losing it's lubricating effectiveness after only 3-5k miles

I hate these posts but...

Unless you track/AX hard or often, as long as you change your oil religiously every 3k miles it really does not matter as long as you use a good grade oil. If it buys you peace of mind then use DT40. If you prefer to invest your money in something else then do that. Either is really ok.

That's pretty much true

IIRC, DT 40 is not recommended for use in racing.
I know many that use Motul 8100 in their race cars. From what I have been told, it has superior high temp sheer. Basically it continues to lubricate at higher temperatures

Does anyone have any empirical data that shows DT 40 is superior other than what a specific person has said?

As far as needing oil between changes, my car rarely needs more than a few oz's between oil changes and that has been true with M 1 as well as Motul which I switched to earlier this year

God forbid you mix another oil with DT40

Really , I just do not see this as the DT40 cannot be that different for a pleasure car than any other high grade full synthetic. I do not want to drop 100 bucks on break in oil just to change to another brand of oil......how much different can the break in oil be from the DT40....looks like DT40 may have been a terrible choice in oils
