I agree, this is something I’m going to keep monitoring. But thinking about each of these samples, each one has progressively gotten more short trips, more cold starts, and less trips greater than say 10 miles. This last sample, it was almost exclusively cold started and driven 6 miles to my...

The intake flexpipe after the filter was replaced after the high silicon in sample #2 and it had a crack in it then. The air filter and piping all appear to be seated correctly and in good shape now. The air filter was just replaced again at this oil change but the old one looked to be in good...

I think it should be nice and hot. Cause that just leaves the fuel that can no longer evaporate out. The lighter fuel that is easy to evaporate out I don’t think really matters.

I think part of it is on the last two changes I have been doing a better job getting the oil hot before taking the sample combined with an intake air leak I fixed after sample #2. I haven't been purposefully lowering the OCI, my wife has just been driving less places the last two years.

Thanks for posting! Looks like a typical engine break in report.

Another yearly oil change done the Honda Civic. OLM was showing 40% at the time of the change. This year it burned ~155 gals for an average mpg of 27.5mpg. OCI was 4074mi, so now the car has 48590mi on it. The report overall is pretty boring. Iron spiked a little, but I don’t think it’s any...

I believe the 2.7L turbomax was design for 0W-20 but currently calls for 5W-30, so it wouldn't be surprising if GM did that again here.

I wonder if it was designed from the beginning with 0W-30 in mind or if they designed it for 0W-20 and are now choosing to use 0W-30 since CAFE fines are zero currently.

Two oil changes done. 2023 Mazda CX-50 2.5S OCI: 9450mi, 323 engine hours, and ~11 months. Out: Mobil 1 ESP 0W-20 and a Mazda 1WPE-14-302 In: Mobil 1 ESP 0W-20 and a Mazda 1WPE-14-302 Got ahead of myself and forgot to collect the oil sample I wanted too. Next time I guess. 2015 Honda Civic...

I bought an LG top load and dryer back in April after my Samsung washer went up in smoke. I was struggling with what to get and short notice but ended up with a higher end LG, I would need to look up the exact models we got. When I was talking with the local appliance store, they said they...

I saw they dropped the prices and that makes the 392 very tempting. But I don’t think I wanna pay the premium in running costs that the 392 and Hellcat would require over the 5.7L. I think the 5.7L with TnG is an excellent middle ground.

Looks great, a new Durango with the 5.7L Hemi and Tow-n-go package, is probably gonna be on the short list for my next vehicle. The logical part of my brain I don't think could justify the 392 or Hellcat.

Do you know if it is a real value or a calculated one?

I haven't seen many UOAs for this engine, but copper does seem high to me, but maybe that's just where the 392 (6.4L) sits for copper.

I have always suspected these engines, the 1.5T and 2.0T, would have lower fuel dilution with the manual transmission vs the automatic since the RPM would generally be higher. I always assumed was because they were running relatively high load (high injector duty cycle for the rpm) at low rpm...

It’s more like a continuation, it doesn’t start burning outside combustion chamber. The ignition timing is just delayed enough that the power stroke isn’t long enough to extract as much heat out of combustion. So more goes out the exhaust and to the catalytic converter.

I think our engines just put less heat into the oil than most anticipate when you're just driving normally and the convective heat transfer in cold weather really limits how high oil temps get.

I had a similar tread about a similar result on my CX-50.

VGTs have been around for ages in diesel applications. They are becoming more common in gasoline applications. I doubt the VGT is going to be the limiting factor from a reliability standpoint on this engine.

I think The Drive is the only outlet to describe it as laggy from the reviews I have watched and read. I think most reviewer say it is fine. Which is about all we can expect from this engine in something the size of a Grand Cherokee. I will probably be curious enough to go test drive a Grand...
