  1. Oil Analysis Thread

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I did a Blackstone oil analysis after my oil change a few weeks ago and started an interesting discussion on the Bob Is The Oil Guy forum. The users there were giving some advice on oil viscosities, why there might be fuel dilution in a direct injected engine, running different octane gas, etc...
  2. 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...
  3. Oil change Analysis.

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I had my dealer do there free oil change at 2300 miles. At 9200 Miles I changed the oil myself and sent it in for Analysis. Two items came up in concern, Silicon that should only have been in there if the oil was not changed. And sodium that could spell coolant leak into oil, or possibly just...
  4. Second Oil Change - Blackstone Used Oil Analysis (UOA) - Comments?

    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...
  5. Used Oil Analysis of Mobil 1 0w30 after 3,000 miles

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hey guys, so I sent a sample of the Mobil 1 0w30 oil I put in my M3 @ 1,000 miles to Blackstone Labs for analysis after 3,000 miles of use, just to see how the oil is handling the Direct Injected engine and my abusive driving style. It looks pretty good to me (and the lab agrees) so I changed...
  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...
  7. 2012 SkyActiv Used Oil Analysis

    2010-2013 Mazda 3 Engine and Performance
    Hey guys, I did my 2nd oil change last weekend and took a sample to sent to Blackstone for a used oil analysis. I got the results today and thought you guys might be interested in seeing them. The wear numbers are still high since the engine is still wearing in, but the viscosity of my oil was...
  8. Official Blackstone Oil Analysis Discussion

    2010-2013 Mazda 3 Engine and Performance
    I don't know how many of you get your oil analyzed, but I am taking my sample today to send out to Blackstone. There is a thread in the MS3 section but none here so I thought I would get one started. You can go to there website and get a free oil sample kit, or if you have a friend who is a...

At...
