    2017~2022 Toyota Mechanic reviews CX-5

    IMO, it’s too early to tell if the redesign of the cylinder head on the 2.5T has truly fixed the cracking issue. Based on the TSB, Mazda redesigned the value guide seal on the 2.5L NA for some reason, then found the failure rate is very high (oil consumption) after several thousand miles...

    What's the tire consensus?

    I used to get only Michelin’s too, no longer. My experience with Michelin tires is mixed. I had blow-out 3 times on my 1987 VW Vanagon GL Syncro while driving on the highway with new Michelin’s. The Michelin’s on my 2001.5 VW Passat GLX had developed dry-rot on the side wall after only 4...

    SkyActiv Oil Analysis Thread

    Sorry to hear that and that’s very unfortunate! I know it’s frustrating as you’ve spent too much time on preventive maintenance for your 2014 CX-5 for the purpose of prolonging the service life. All the efforts on time and money seem to be wasted now. Looks like your 2.5L is just started...

    2014 CX5 ATF 1st drain and fill at 140,000km

    My take is if you plan to use OEM ATF, you can just do one drain-and-fill with very minimum risk of having any ill effects. But since you’re going to use aftermarket ATF FZ, mixing fluids half and half with different (or unknown) characteristics together will never be a good idea IMO. I’d do...

    2013~2016 Belt Tensioner - Shouldn't this be a warranty item?

    I’ve learned the lesson during the long period of my DIY experience. I’ll use OEM parts all the time (belts、filters、ATF、etc.), even though they usually are more expensive. OEM parts will be the most compatible, and the best fit for replacement. This prevents me wasting my valuable labor time...

    2017~2022 CX-5 Abnormal Oil Use

    I agree. Some marginal improvement on mpg is possible with GF-6 oil; but not 19 ~ 39% improvement!

    2015 CX-5 Rear Caliper bracket bolt bigger than hole

    You bought your 2015 CX-5 with 30 ~ 35K miles; but you didn’t say what is the current mileage? Brake calipers usually don’t need replacement under normal usage unless you have a 2016 / 2016.5 CX-5 which has defective manufacture process with newly introduced EPB at the rear. Your quick...

    2014 CX5 ATF 1st drain and fill at 140,000km

    Yes, ColoradoDriver here did his 3X ATF drain-and-fill at about 80~90K(?) miles with no ill effect.

    2014 CX5 ATF 1st drain and fill at 140,000km

    I’d suggest you to do the drain-and-fill multiple times with a specific interval (most people do it 3 times), especially you’re going to use Ravenol ATF FZ. You can only drain about half of the old ATF even if you drop the pan. Mixing with Ravenol ATF FZ which is supposedly full synthetic...

    2017~2022 CX-5 Abnormal Oil Use

    I agree. There’re plenty of reports, especially on Toyota vehicles, that the pre-GF-6 0W-20 oil is lack of protection to timing chain. Hopefully the current GF-6 oil can really do a good job to protect timing chain better.

    2013~2016 Belt Tensioner - Shouldn't this be a warranty item?

    Based on some reports, I believe if you use OEM water pump stretch belt, it’d be easier to put on as the one-size-fit-all aftermarket belt (Gates?) seems to be a bit smaller than OEM belt.

    2017~2022 CX-5 Abnormal Oil Use

    No need to wonder. Here are Mazda official engine oil viscosity charts for SkyActiv-G 2.0L / 2.5L and SkyActiv-D 2.2L used in Europe and worldwide, and 5W-30 oil is listed as recommended oil by Mazda:

    How to temporarily disable headlights?

    That’s in my 2018 Toyota Yaris iA which is a Mazda2 in disguise. Toyota has always been offering an easy way to turn off the DRLs and they just have a build-in DRL switch position on the headlight switch stalk. Apparently that’s the requirement by Toyota when Mazda was building the Yaris iA...

    How to temporarily disable headlights?

    If you read the entire thread with link in post #20, you’ll see many 2020 and newer CX-5 owners did it with that Mazda official procedure unless you’re in Canada. People said they failed to disable the DRLs with the procedure most likely they missed or misunderstood some steps.

    CX-5 Oil filter (turbo)

    Mazda has never published any data on its OEM oil filters other than some document saying the OEM oil filter used on SkyActiv 2.0L / 2.5L non-turbo engines is a high-flow oil filter and don’t use earlier version of OEM oil filters used by other Mazda engines or it could trigger the CEL. Wix...

    How to temporarily disable headlights?

    Or just use Mazda official instruction mentioned in post #20 previously to disable the DRLs.
