  2. BlackStone vacuum pump

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I went to get an oil change all prepared with the BlackStone bottle and the dealer told me they can't do it because they suck the oil out with a machine. Next time, I guess I'll have to either go somewhere else where they let the oil drip into a drip pan or buy the BlackStone vacuum. Does...
  3. Used Oil Analysis - 1,027 miles break-in (Blackstone Labs)

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Just wanted to share my UOA with you all. There's a lot of debate as to whether or not oil needs to be changed early (whether that be 500, 1000, or x miles) for break-in purposes. The oil sent in was the factory fill which is Mazda's proprietary 0W-20 with molybdenum. Personally, I am in the...

    2010-2013 Mazda 3 & Skyactiv Discussion
    Here's my second UOA. Pennzoil Platinum 0w-20 with Mazda oil filter. I was going to change the oil at 5000 or 6000 but I have a weird living arrangement with my parents so I don't get to use the driveway/garage often. First UOA is here for reference...
  6. First Oil Change - Blackstone Used Oil Analysis - Comments?

    2010-2013 Mazda 3 & Skyactiv Discussion
    Just changed my factory fill at 3900 miles. Lots of wear/break in on the engine. Didn't go above 3000 rpm on the first 1000 miles, then slowly pushed it to 4000, 5000, redline at every 400 miles. 50/50 city and highway driving. Filled it up with Pennzoil Platinum 0w-20 and replaced with Mazda...
