Hi all, I subscribe to mototuneusa's way of breaking in an engine. Go pick a gear like 3rd and accelerate moderately then release and coast back down to 1500 or so and repeat a few times and then go up a gear and repeat. That puts a load on the rings and seats them into the bores during the acceleration part. The coasting creates a vacuum and cleans the junk off the cylinder bores. Doing this prevents the cylinders from glazing over which will prevent the rings from sealing any more.

Anyway my wife purchased one in Wi as we were driving back to Co. I was able to do this break-in for about 30 miles (vehicle had 80 on it) and then told her to vary the throttle and speed as she followed the jetta tdi I was driving. Put about 1,000 miles on it in two days and I changed the oil last night. I think it's friggin craaaaaazy to go 10,000 miles with a brand new engine and the same oil. It was only $25 for oil and another $10 for a filter.

I also took the belly pan and cut a nice oval shape out of it with my jig saw (two 4" diameter circles with the centers about 2.5" apart with the drain plug in the center of the first one), didn't even bat an eye at doing that as I recently got an aluminum pan for the jetta (stock plastic cracked after hitting a turtle (Wi term for ice chuck from behind a wheel that falls onto the road)) and cut a similar hole on that for oil changes.

Oil was beautifully sparkly as pretty much all new engine oil is so I'm glad I did the first change already. Now to order a magnetic plug and I'll probably change the oil a couple times in the first 10,000 before going to the 10k oci. After all it's not really that expensive compared to possible thousands of miles longer life and less engine wear.



Side note, brought a craftsman mower with a Briggs & Stratton engine that's their "Just check and add" oil that never needs to be changed.. Well it takes 1/2 a quart so I got some 5w-30 dino oil and did two 15 minute break-in runs before putting in the oil that came with the mower. The first oil change was very very sparkly and the next one was much less so. I don't think an engine (especially one without a filter) is going to last many hundreds of hours with that grit getting splashed on the bore every revolution.




So is everyone going to wait 10,000 miles for the first oil change here?

I expect that very few invested owners will wait the full term for the first oil change. Personally I've always done it much sooner just to get rid of all the metal shavings. For what it costs it not like you're saving all that much by waiting.

My experience on VW with timing chains (I am a big VR6 guy, but don't know if the 2.0 TFSI uses chains or not) is that the wear on the timing system is more of an issue than say rings in regards to longer oil changes.

Changing more frequently is a great idea, I just wish the 3.6 wasn't such a royal mess to change...90% cleanup 3% filling and 7% removal and draining. So it seems... Hopefully your 2.0 is way easier.

Around 7,500 miles is probably the longest I would go before changing, but much less during the initial break in period. With all the additives in fuel now, I think the 10,000 mile interval needs to be updated, at least for America.

The newest gen 3b 2.0 is timing chains from what I read. Rings don't really wear once broken in properly, the cylinder bore would probably wear faster. The good thing is the 2.0 holds something like 6 quarts as the 5 quart just barely tickled the dipstick. I didn't pay attention to the amount it held and just grabbed a 7 quart pan I had handy and I ended up spilling a little when I had to move the pan to get measurements for the cuts.. Didn't realize it was that full until I went to pull it out, which I did very slowly! So more oil means it should last that much longer which is good for the 10k oil changes. To speed them up I cut out the skid plate where the drain plug is. Sure I might get 0.001% worse airflow under the car but compared to the pita it is to pull the pan off I don't really care.

Also I have a 2012 jetta tdi and they do 10k oil changes with 5 quarts of oil, many folks who do oil analysis end up finding out the oil is still good out to 15k miles or higher. Granted the tdi is a 130k timing belt so there's no chain wear present.

If you want cleaner oil changes without going under the cars then do what the dealers do and suck it out of the dipstick tube. In fact that is what the online service manual site that most mechanics use says to do and if you don't have the equipment then do it through the drain plug.

With the high grade synthetics available today the limiting factor is your oil filter. The oil filter will need changing before the oil does.

I've been changing my own oil for years and run synthetic in my Audi TT. I checked my new 2019 Atlas at 4200k and was very surprised to see how dirty the oil was - looked burt to me. Even though I have my "first" 10k oil change all ready scheduled at the dealer as part of the included maintenance I took it in for an oil change and paid out of pocket. I want to gage this myself with some picture and samples over time but I'm not feeling fuzzy about letting the oil go for 10k.

Suggest everyone keep an eye on their oil in these Atlas's.

The engines in the Atlas (3.6 and 2.0) have both been around a long time and have a long history of being ok with the factory-recommended 10K oil changes backed up by used oil analysis data (using the correct oils with VW502.00 approval). Using the color of the oil as an indicator of when oil is ready to be changed has no valid backing. Get a UOA and see for youself. I'm doing 7.5K on my Atlas with the 3.6 just to have it on the same schedule as my tire rotations but we only drive ~12K a year so 1/2 changes a year is no big deal.

Oil is cheap and peace of mind is priceless :wink2:


I started following this years ago, 1,200 first dump then 2,500 after this it's based on time and condition
for the climate I live in as this unit will not rack up a bunch of miles.

I also do the " Old School " brake in including the 4Motion drive-line.

Why not 2K then? At some point you have to admit that changing your oil at intervals like this with modern synthetic oils is a complete waste with no data backing that it is necessary. I'd say 5K is the min unless you don't drive that in a year. Someone always says "I've changed my oil like this for X and Y and it's always worked for me." Well I've had numerous VWs with 7-10K oil change intervals with no issue so how does that work? My 2000 Jetta is still running strong at 280K with a neighbor who bought it at 10K oil changes over a lot of that 280K.

In past the vehicle in this position was not driven that much, however now that I'm down to two it will
most likely have more miles in the same time frame mostly city & suburbia conditions.

I understand your comment on no data and your correct, will see how things turn out.


Thanks for the comment & insight :wink2:
