2016 GT Break in period/gas mileage

The thought behind the 1,500 mile oils change actually makes sense to me. They said because it's a new engine, there will be wear in and therefor metal particles. Better to do an early oil change IMO then risk metal particles wearing things down. I'm a military aircraft mechanic, so it seems to make sense in my head, no sure if the reality is true or not.

I don't know for sure, but some Mazda techs told me that all Skyactivs have special oil additives in the new engines to help "absorb" the particulate matter, and for better break in(mind you these were the techs who told me the 0W20 oil we put in, is non-synthetic and I made a fool of myself on this forum). From what I know and have seen, stick to the mfr claims. That way, if a warranty issue presents itself, there's no worry that you did something wrong to void your warranty. They built and designed the car, I think they know what oil change interval should be.

Yeah, be careful of these "free" oil change offers from dealers! You had a VW and you should have heard the class action lawsuit for oil sludge issue on 1.8T/2.0T. It's actually not entirely VWoA's fault as many VW dealers were using cheaper and widely available 5W-30 conventional oil instead of recommended 5W-40 synthetic oil. Dino oil just got cooked too easily by extreme heat from turbo charger hence the oil sludge. My Mazda dealer uses an unknown brand of 0W-20 oil hence I declined the "free" oil change. But you can always request Mazda moly oil available at parts department and pay some extra.

I used to do the first oil change early too. But after reading many articles I changed my mind. Honda even specifically warns the owner not to change oil early for the first time in the owner's manual for break-in period. The reason is a special break-in oil is used from factory-fill.

I used to be getting VW all the time but our last Passat is a total disappointment! It burns a quart of oil per 800~1,000 miles since new. It has an Audi 2.8L V6 and I thought Audi should have better quality control than VW. A friend's son has a '13 Audi A6 and his dealer just told him his A6 needs a whole new 2.0T engine shipped directly from Germany! Luckily the engine replacement is under warranty!

You have a 2.8 V6 that burns oil? Wow that's a first. My brother in laws 2002 Passat 1.8t with 270,000 miles burns next to no oil. Of course some use of oil is normal. He doesn't need to top it off between 8,000 mile changes while my mother 2014 Tiguan with 30,000 miles needs a liter every 3,000 miles...
