- 2014 CX-5 Touring
Well great. Oil analysis found evidence of coolant in the oil. Not what I wanted to find. I’ll post the actual report tomorrow.
Saw another post that a forum member replaced head gasket and is changing oil like every 3000 miles to hopefully avoid engine damage.
oh sorry I forgot I removed the vehicle info when I cropped the report. It's a 2014 CX-5 Touring, 2.5L NA engine. Manufactured January 2013.Saw another post that a forum member replaced head gasket and is changing oil like every 3000 miles to hopefully avoid engine damage.
What year do you have? Is it a turbo?
Bummer. So, now what to do with that information is the question eh?Definitely not what I wanted to see. Just got the loan paid off last summer, too.
I could not see any evidence of oil in the coolant visible under the radiator cap. And the used oil that came out looked like normal, dark colored used oil. There was nothing to raise any concerns of anything.How about the oil on the dipstick, does have like a milky texture? Can you see any trace of oil floating in the overflow tank?
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.I could not see any evidence of oil in the coolant visible under the radiator cap. And the used oil that came out looked like normal, dark colored used oil. There was nothing to raise any concerns of anything.
And yeah I’ve had blown head gaskets on other cars where coolant mixed with oil. It looked nasty. Not seeing that here.
Is there any sort of oil cooler where coolant could have mixed with oil? Any sort of sandwich plate with coolant lines near the oil filter? I haven’t looked around that close to see if the 2.5L NA Skyactiv engine has anything like that.
Looks like I'll be doing an OA a few times before my extended warranty is up. Wonder if the 3 piece block design is a consideration in the mix?Yes. Try a different lab. Also see "2015 cX5 2.5 skyactiv coolant in engine thread"
Seems the Mazda engines explode just after year/mileage warranty is up.
There are probably alot more engine failures that we are not aware of because those people are out of warranty and don't visit forum sites.
My engines in my Ford's, Chevys and Toyotas, etc. all lasted approx. 12 to 14 years/ 200,000 miles and beyond. Most vehicle were sold or had frames fail and rust before the power train/drivetrain
Although the Mazda is fun to drive, if the cars are incurring heavy replacement costs before there due time, for me it makes more $$ sense to go back to Fords/Toyotas for keeper vehicles. Or if really want a Mazda, just lease them instead.
If my 2018 has engine failure before a 10 year / 180,000 mile timeframe, will definitely switch back to Ford/Toyota.
For now maybe you can just keep switching oil every 3000 miles like the other forum member did. If your frame is in really good shape then maybe consider an engine fix. If the frame is rusted bad then maybe save your cash and get a new car instead.
If you cannot reach any oil, blackstone will send you a smaller tubing. Just contact them.Hi All,
Knocks on wood... No issues with my 2020 CX-9 so far, but with the bumper to bumper warranty up around the end of the year I just picked up a Blackstone labs oil sampling kit to test my oil. The diameter of the tube that came with my oil sampling pump fits inside the dipstick tube but bottoms out before it gets to the pan.
I've been getting the oil changed at the dealer to help maintain the paperwork trail while the car is under warranty. So hoping to do this without changing the oil. Any suggestions on a tube diameter that is narrow enough to reach the pan?
