- 2014.5 CX-5 GS FWD 2.5L
Ok, guys I'm at the end of my rope and need some help here. Sorry for the long read, but had to put all the details down.
This issue has gone on for a long time and it's definitely not getting anywhere with Mazda. Dealer or the Canadian help desk.
So I have a 2014 with the 2.5L gasoline engine. Checking the dipstick, the oil level is all over the place.
First off, the level is always checked the same. Parked in my garage, and checked the next morning before it starts. There's no arguement about a level surface and if there was time for all the oil to drain back into the pan.
I've actually kept strict records for the last 2 months.
Driving around town, start & stop, cold starts, etc, over several days, the oil level will slowly creep up the dip stick. If there have been a couple weeks around town, the level will easily be 1/8" above the full hole on the dipstick.
Then when we go for a highway trip, the oil level will drop a good 1/4" when I check the next morning. Drive around town, and the level will slowly creep up again.
It's like around town the level goes up and on extended driving, the level will go down.
This was first noticed at oil change #2. The oil level was a good 1/4" above full. I had the oil tested and it had 12% fuel contamination. It was blacker than black and poured like water. After that the dealer changed the oil 3 times within a month period and eventually changed out the high pressure fuel pump. At first they thought the problem was solved, but here we are 10,000kms later and the same thing is still happening. My coolant is good, so the only thing left is fuel.
I know these DI engines like to over fuel when cold and some contamination is normal, but not this much. And if the dipstick shows that much overfill, I can't see it burning that much fuel off on a highway drive. Frick that much fuel I would expect a small explosion under the hood.
I guess I could solve this by never checking the oil again, and as long as we do mixed city/hwy driving, it should average out by the next oil change.
Like I said, I'm fishing here. The car is at the dealer for other misc service work, but they shrug their shoulders at this oil issue.
So any ideas out there? Do you guys check your oil regularly? Does it stay fairly clean between changes? I'd be curious for you city drivers, check before and after a long road trip.
Or maybe this is pefectly normal for the Skyactive technology??
