Im going to do one more oil change with DI40 on Macan and see if engine sounds better over time. As of right now, as i mentioned, valve train is louder than i expected based on all of good reviews on this oil.
Thanks for all the info
I have been running the DI40 for a year in my 996.2 and the engine seems to like it. I am one of those guys that has barely used the radio over the past 22 years. Instead I put the windows down and listen to everything. It took a couple of hundred miles and a track day, but the engine does run quieter.
Even though Lake highly recomended it, I wasn't sure how the engine would run with it. I am pleasantly suprised with it and will continue using it. But will try DI50 next to see how the engine responds. One of the things that surprised me was when I cold started it on a 20 degree day earlier this year. The car sat for a couple of months on a trickle charger. Sounded like a warm weather day startup. I was pretty impressed.
It may be that the Macan may respond better with another oil. But so far, my m96 has responded well to DI40. For background, i ran Mobil 1 from 2002, them moved to Millers Nano 5w40 for well over a decade and now DI40. I loved the Millers and it treated my bores well, but the car seems to run the best so far on DI.
Time will tell if it's as good as they say. I hope so. So far the oil tests have been very good on the 996. I am going to try it on my Audi Q7 3.0 next. Just got the service department to verify its use won't effect the warranty. I have an oil change coming up with the Q7 to get a read on its condition with Castrol and then making the switch.
@malahhaor Next oil change, please collect a sample of the oil and send it for analysis. If the valve train is clattering in a way that is bad for engine wear, it will be seen in the results. Here is the UOA history of my Cayenne. The right most numbers are with Mobile One. The other 2 are DI40. With 165000 miles, I'm pretty happy. And yes, the valve train and injectors make a bunch of noise, when the hood is open and I'm standing over it. I can't hear it in the car. The data will guide you. Please don't take our word for it and then blame us later if something truly bad is going on. Note: I change oil 2X per year but test only 1X per year. The mileage value is for previous 6 month only, not the entire year.

Good luck with finding the right oil.
Great info. Did you ever run DT-40 and how did it compare to the others? Curious because I’ve been using DT40 for a while, getting ready to try DI40 next oil change.

Never DT40. Earlier in thos thread a bunch of us post virgin and used oil tests for comparison. Having used Millers Nano on the track and street, I called Lake up to discuss my tests and look for a recomendation for oil that is robust enough to do double duty like Millers. He said DI40. About that time the video came out that started this thread and the thread has taken on a life of its own.
OK I suppose I can get away with 5w for Macan GTS in Chicago winters. But it looks like they only make 15w-50? I drive my Carrera all the way up to when snow and salt hits. Is 15w ok for freezing temps in the cold AM start?
A 5w40 is perfectly suitable for use in cold Chicago winters, so if you are considering using a DI oil, I would say DI30 or DI40 would be most appropriate for your Macan.
Funny thing is they mention the extra cleaning, but not the fact that is got a bunch of voodoo to stop foaming..
GM has had a lot of trouble (So has ford) with their Zippy highly tuned up engines ruining timing chains
and that was when they came up with the Dexos rating. Of course the oil change manager in their cars is
calibrated for a 9000 mile oil change with some adjustment to account for usage.
My local dealer service write told me the cars that change between 5&6K miles don't seem to have the problem..
Its all the 4cy na and turbo and V6 Na engines that seem to have issues with GM..
Most of the cars rev to 7K and have automatic transmissions though..
Yep, I had to do the timing chain on my 2.0T at 75K miles. When the timing cover was removed I discovered the tensioner was extended so far it was about to come out of the housing. This was right when my CPO ended and I changed to DI40 right after it expired and it hasn't stretched at all since (you can measure in VCDS just like you can with Durametric). This is a major problem on small displacement turbocharged engines -- they are really, really hard on the oil. I am changing my oil every 3K miles now.
I concur. If any of you want to run DI40 in place of DT40 or DI50 in place of FR50, that's not a bad idea either.
With respect to DI50, is the 15W cold viscosity an issue? Technically a 15W should be good down to -13F and erroring on the side of conservatism it can still be very cold and it would still flow well. Probably not a great idea to do cold starts with this engine in such low temps to avoid bore scoring in the first place but that aside and just playing devil's advocate, are there any caveats to running DI50 in these cars year round like in the winter? For the air-cooled engines I know 15W is pretty typical but curious your thoughts on the water-cooled.
p.s. Huge mistake showing my wife the pictures of your Airstream. She LOVES it and now all I'm hearing about is how she wants one just like it LOL
