I'm guessing the Crosstrek engine bay must be a bit tighter than on a Outback. When I did the plugs on mine a few years ago, the only things I had to remove to access the plugs was the airbox/tube. It was my first time doing plugs on a Subaru so it went slow figuring all the quirks out...
0/5W-30 is all that engine needs. It will run quieter and will not affect fuel mileage at all. And, depending on what year it is, will help to minimize oil consumption. VRP 5W-30, as mentioned, is the best option for cleaning the rings if it is already a drinker. Its what I currently have in my...
I did the first drain on our ‘26 Carnival at 1,200 miles and it was fairly sparkly. The second drain at ~4,400 was much cleaner.
There have been lots of reports on here of the first drains being sparkly, across a wide range of engines and manufacturers. Just the nature of the beast.
To @kschachn ’s point, OEM oil specifications are just setting a minimum spec. There are plenty of other specs, mainly Euro, that meet and often exceed the Dexos spec for instance.
A higher/better spec will not cause a mechanical failure that a lower/less stringent spec would have prevented.
Our ‘26 Carnival calls for 0W-20 and 5,000 mi “severe duty” OCI’s.
I run and will continue to run for the foreseeable future Mobil 1 ESP 0W-30 with 4-5,000 mi OCI’s.
Fuel system cleaner gets used once per OCI.
My mom had a LeBaron GTS turbo during my early years, it was a 86 or 87 I wanna say.
I barely remember riding in it as I was single-digits young. My dad had to replace something I remember, intake gaskets or something related to coolant. I remember he had part of it disassembled.
Anywho...
I remember this tool kit being a lifesaver back in the day when people would snap it off trying to remove.
After getting it out one way or the other, most converted to a standard hose fitting like you did.
I grew up with a lot of 90’s GM vehicles so they always have a charm to me.
When I pulled the intake to do the gaskets and replace the injection assembly, I cleaned and reused the OE disconnect piece. This was almost 20 years ago now and before I had learned all the horror stories of that thing snapping.
Knock on wood it’s still holding up nice and dry to this day.
