Here’s my review of changing the oil in a 21. It sucks unless you have a lift. The belly pan underneath makes no sense. I see nothing any different that needs protecting than my wife’s 18 rogue or even my 09 Altima. The oil filter is on the front as opposed to the passenger side. I drained my oil at 1200 miles after removing what seemed like 100 plastic clips and 2 10mm bolts. The oil filter at the factory was destroyed removing it as it seemed to be installed by the strongest person on the assembly line. 5 quarts and 10 ounces later an it was done. Definitely more of a pita than nissans easy oil change vehicles of the past. I’ll be doing 4-5k intervals on this car and will dread every second of it. I’ve already placed an order on Amazon for 100 clips for the belly pan as I’m sure I’ll be needing them. My experience with clipped panels, is once removed from factory install your sure to end up with something that’s gonna rattle and vibrate moving forward. I’d have been much happier seeing all 10mm bolts instead of cheap plastic clips. I love the car and was happy to see they stuck with a tranny drain bolt and I’m hoping the service procedure remains the same, as I’ll be dumping the factory cvt fluid at 10k and using eneos fluid for 1/4 the price of relabeled Nissan fluid.

I must admit, it seems like Nissan engineering almost went out of their way to make everything on the gen6 Alties difficult. Even the plastic pawls holding the seat trim are so stiff that only Godzilla can pull them off cleanly. Vis the engine, the arrangement is so convoluted that you can't replace an EGI Harness without dropping the engine out of the car. As I've mentioned elsewhere, I love the VC and congrats to Nissan for making the first reliable VC powerplants, but from the standpoint of repairability they're almost nightmarish.

Helpful hint for the belly pan, those pushclips get stubborn primarily from dirt, just like connector latches. Hitting them with a little WD40 or PB Blaster makes popping them a whole lot easier, and hitting the back sides with some before reinstallation makes them much less likely to stick the next time around.

That’s why I stayed with the 2.5 over the turbo. I know that early 2.5’s had some pre cat issues, luckily the 03 I had never did. In fact I never researched it nor did the dealer ever say anything. All I know is, when it was totaled with 176k on it , the engine didn’t use a drop of oil and I was none the wiser. In fact, it still had the original alternator and starter. The 2.5 IMO has proved itself every bit as reliable as the 3.5. I had a 2000 Volvo S60 and wrestled with that belly pan for yrs before I finally chucked it. I see nothing exposed on the 21 that justifies adding one.

It's not necessarily exposure, we saw some issues with the late gen5's ('16~'18) actually throwing A/F sensor codes because of ventilation in the wrong places with the pan missing. We haven't seen anything like that with the gen6's, but the point is, everything is so integrated on the new models that you never know.

In my experience the QR's are more reliable than the VQ's. No chain tensioner issues and a bottom end so strong that they even survive hydro-locking 9 times in 10. IMO the best 4-cyl ever built, hands down.

So is this engine in both the Gen 5s and Gen 6s?
I read that the 2.5 liter was "changed" but have no idea if this was mere tweaks or a new design.

No, gen5's were the last QR's in the Altima. Gen6's have the new P series Variable Compression engines.

But the base engine is not variable compression but a 2.5 l 4 cyl...?

Nope, they're both VC. The 2.5 is just NA while the 2.0 is turbo.

Yeah I had no idea either. I assumed the 2.5 was the 2.5 of old. I guess taking another 1/2qt of oil and the filter being in the front of the engine should have tipped me off. I will say the mpg is incredible. Not even fully broken in and I got 39 on a 90 mile round trip doing 80.

The official designations are PR25DD for the 2.5, KR20DDET for the turbo.

I've said this in other places, but it bears saying again. I think part of the difficult layout on the PR and KR are because it's an infant technology. It will take an iteration or two to clean up the serviceability issues, but the end result will be worth it, especially in the turbo world. Wastegates are basically wasting energy by definition. The engine used power to build up that pressure, then it's literally "wasted" out the gate without accomplishing anything. The option of dialing back compression to cram more air into the cylinder instead of blowing it off has barely been explored, but I think it will be a whole new turbo world once tuners discover the power of VC and use it to the hilt.

Awesome!!
Other car companies will sell you a hybrid to get those kind of numbers! :lolling:
Doing it without the cost and complexity of a hybrid is a real win all around. Go Nissan! :bigthumb:

We’re not going to have a choice on electrics in the future. Better buy yourself an electric car gas can (portable generator) before the big boom. One of my friends who swears by his Tesla has been towed more than once when it ran out of juice.

Plug-in electrics are not the future, folks. Methane-hydrogen fuel cell systems are, but that's another discussion for another thread.

I will say, though -- a dirty little stationary engine making juice to get a Tesla home expresses exactly what's wrong with plug-ins as a concept.
