    What have you done to your CX-9 today?

    Got this damage fixed. An old dude in CRV backed up when my wife was driving by. At least no hiccups with insurance (Geico) and no excessive wait on parts.

    Hey guys, do you have the same bolts sticking down out of the rear suspension? Accidentally noticed it today, looks ugly and not right.

    2016~2021 Consumer Reports - 2020 CX-9

    No offense guys, but all those individual examples are simply survivorship bias. Yes, every two tears as a general rule sound like overkill, especially if the climate is dry and no mountains driving. Personally, I think it is worth doing every 4-5 years. And 100% if buying a used vehicle. Does...

    2.5 Turbo - Oil Fuel Dilution Issues?

    Nope. I gave up since the good dealership nearby started to ignore me. Others are further away and I did not bother. Now I'm guessing, they might be dealing with people that require engine replacements... so it's unlikely they have enough loaners for a guy with some harmless oil dilution :) So...

    Turbocharger information that was a bit alarming...

    I have a natural setup to test this for the last 7 years. I live on a hill and every time a get home its a steep uphill for half a mile. then 10 sec of a minor uphill and 10-20 sec of idle rolling and parking before i shut off the car. It is naturally hard to break 30sec rule too badly...

    Oil Analysis

    TBN at 8.7 looks waay too good for 6k miles in turbo engine. Viscosity looks a bit optimistic as well :)

    2016 CX-9 Oil Analysis

    Low flashpoint and lowish viscosity could be a sign of fuel dillution of bit more than 1% that they guestimate. But it's good to see there is no impact at this mileage.

    How reliable has your CX-9 been?

    2019 cx-9 with just 20k miles. So far worst reliability out of 4 different cars with turbo Di engines I had or helped to maintain. Most importantly got an issue that required towing out of nowhere. I try to know and maintain my cars well so I can rely on them in long trips - therefore this is...

    SkyActiv Oil Analysis Thread

    if BlackStone shows 2,5% dilution, backed up by low viscosity, chances are dilution is 5%+

    SkyActiv Oil Analysis Thread

    Blackstone is well known as unreliable source for fuel dilution checks. There are references that they basically derive fuel dilution from flashpoint test. You can just ignore it and if you smell gas in oil - send it to Oil Analyzers. Please see my experience below: Post showing differences...

    2.5 Turbo - Oil Fuel Dilution Issues?

    Missed this thread? So my issue is back. It took some time to validate due to COVID apparently... After the "leaky injector change" oil smelled ok after first 1k. After that I did not check much. Got another issue with engine harness and had to tow it for repair. At 3600k on oil I send it to...

    SkyActiv Oil Analysis Thread

    Once I got first analysis with 5% in 3500: I changed oil type, switched from Regular to Premium and did at least 70% highway driving and on top of that it was summer instead of winter. And I got 3.8% fuel in 2100 miles anyways :) I think something happened around 6-8k After first oil change...

    Spark Plugs at 40k?

    There were many cases where car manufacturer declares lifetime ATF fluid, but gearbox manufacturer declares 40-60k miles :) Do Mazda use their own transmission or 3rd party?

    18' and 20' what should I do ?

    For bad roads 18" is an easy choice :) It's simply better for your car on the long run.

    SkyActiv Oil Analysis Thread

    A heads up for those who prefer Blackstone and gets low viscosity. I would recommend testing with OilAnalyzers as they actually check for fuel in oil. Sample below showed 3.8% from OilAnalyzers and no fuel with Blackstone. I left a note in comments that fuel dilution is suspected. The car...

    2.5 Turbo - Oil Fuel Dilution Issues?

    One more point on labs. The Blackstone is very popular lab, but they don't do proper fuel dilution analysis even though they provide the "Fuel %" value in the report. They simply derive it out of flashpoint test. Their staff seem to think its a reliable test. I have send my previous sample with...
