I recently changed the oil/filter in my 2019 mazda 3. Previously, it has only seen the OEM 0w-20 oil purchased from the mazda dealer and the OEM mazda filter. This time, I used 0w-20 Mobil 1 EP and a fram ultra xg6607. After changing the oil/filter, I had a noticeable hesitation and lack of acceleration when accelerating for the first 1/2 mile that I drove the car. No service engine light came on. The car only has 8,000 miles on it, and this has never happened before since the car has been in use for the last year and a half. The temperature outside is 90 degrees, so it wasn't cold. The oil level is good, and the oil filter was "primed" prior to installing it. This concerned me a bit, so I did a google search and found several other people discussing random hesitations after installing a fram ultra filter. I'm unsure if it was related to the filter, the oil, or if it was just a random coincidence. The hesitation only lasted about a 1/2 of a mile, and I have not noticed anything out of the ordinary since. The fram ultra xg6607 is a tiny filter, so I may try to install the larger XG7317 next time. Or maybe I should use a less restrictive filter? I don't really care what filter I use, I simply used the fram ultra bc it's supposed to be a good filter and I can get them locally for $8-9 (the OCI on this car is 10K miles). However, why did this happen right after the oil/filter change? Maybe it took a little time for the oil to penetrate/flow well through the more restrictive, small xg6607 filter, causing the lack of acceleration? Maybe it's the oil that I used? Maybe it was a fluke? I'm just stumped bc this has never happened before. Any ideas?
