    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    I started looking around and saw this wire on the passenger side of the bay that goes from a bracket on the head to a bracket by the strut tower. Also found two holes on the back of the engine, the last picture shows one of them. If that's on the head, then it's a pretty easy task. Two is better...

    What 5W30 oil brand do you use in your CX-9?

    I thought it's ok to mix if they're the same type (synthetic/conventional)? 😅 The CX-3 has gotten mixes between different brands and viscosity (0w20/5w30). Will use VRP for at least 4 cycles. There may or may not be any difference that I can feel.

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    AL you had me at the first paragraph of post #1 (and #63). I must have come across your thread before but cylinder head sounds deep. That last pic got me curious. Definitely my next project.

    5w20 or 5w30?

    I believe you can. The owner's manual is a bit confusing though. If you flip to page 401 of the PDF, it tells you what to use depending on where you are. 5w20 was recommended for fuel economy. https://www.mazdausa.com/siteassets/pdf/owners-optimized/2010/cx7/2010-cx-7-owners-manual.pdf I have...

    Remotely Mazda: Used Oil as Wood Stain

    These two models were half off so I decided to assemble both using one set of acrylic pens (12 colors). The quad bike gets red body panels, black tires, white rims, silver gears, and gold suspension parts. There was not much ink left in those colors. The other one is going to be a...

    Check your Coolant Level (In your Radiator, NOT just the Expansion Tank)

    My original cap was 8.5 years old and 167K miles (269K km). It wasn't exactly responsible for any particular symptoms. I should put it back and monitor for problems. 🤔

    Check your Coolant Level (In your Radiator, NOT just the Expansion Tank)

    I replaced mine for the same reason as AL stated above. The old/factory didn't look deficient, but the new one fits a lot tighter.

    What 5W30 oil brand do you use in your CX-9?

    Valvoline Restore & Protect 5w30 is currently $29.97 on Amazon. How much is SuperTech by the way? I know at least one other member here who uses SuperTech oil/filter with short OCI. For my lifestyle, $30 oil plus $15 OEM filter is $45 for 5K miles every two months. 45÷60=0.75. Less than a buck...

    Green coolant?

    Thank you! 115C is about 240F so that's crazy hot. Now I know what signs to watch out for. 👍

    What have you done to your CX-3 today?

    5K miles oil/filter change today (from 165,550 to 170,526 miles) Using VRP for the first time. The oem filter was still tight and came off by hand. It is going to Pete once fully drained. Start to finish took about one hour. Got some yard work done while waiting. I used to wait for the drip to...

    Green coolant?

    There was probably a change in the range of fluctuation.

    Green coolant?

    Normal like in the 190s and how much higher did it go when idling? I didn't know it wasn't supposed to do that. 😭

    Dead Battery Can Affect Fuel Gauge Reading?

    Glad that everything is back to normal! I thought there'd be warning signs before fuses, relay, or batteries go out. In my case, things got gradually worse over time until I got stuck. 😬

    What 5W30 oil brand do you use in your CX-9?

    I understand where you're coming from. Besides getting samples analyzed, have you tried cutting open your used filters? 🙂

    Green coolant?

    What does inconsistent temperature look like? 😅 My MAF sensor reading is all over the place.
