Lawsuite wise yes. Stockholders could care less if a person gets less power so long as they are less likely to sue. That's my point.

Like everybody else, I want to get the most out of the car and this seems to be a very controversial topic.
because the manufacturer only wants the car to survive up to a certain milliage then they put their zero fucks hat on.

making a car that lasts forever is bad business

Pretty sure this is the only Subaru that doesn't take 5-30.

Not true, the 2012 Impreza 2.0 and 2011-2012 Forester non-turbo also use 0W20. I guess my "most" comment was more related to the Toyotas, but there are other Subarus that are already using 0W20 synthetic factory fill as well.

Dunno how I feel about 0w20 still, even the manual says to use a 'higher' grade oil if the car will be operated "outside of normal driving parameters"

In all my inline 4 motors I have sworn by 0w30 or 5w40 depending on driving style and ambient temperature. Im probably going to be using 0w30 in this engine, too.

I don't like 0w oil,

I will be running 5w-30 or some close facsimile there-to,

I love 0 oils. I would never go above what a manufacturer states, infact I will normally go lower. In this case tho, Toyota/Subaru had already picked the oil I was planning to use from the start which is 0-20.

So you're going to be flooring it to 7000 rpms right off the lot?

The "run it hard" opinion hit a resurgence with a website from an air cooled motorcycle mechanic. Aside from the page being focused on motorcycle engines, his hard break in technique for the street only takes the bike up to 65 mph - that's fast for a bike but not much for a car. Bikes are also thousands of pounds lighter than cars so the engine doesn't have to work very hard if you're driving "normally". Some of the misunderstanding is that one person's babying is another's beating. The advice also says that the critical window of opportunity is only 20 miles or 9 dyno runs, then it becomes 200 miles for the street - which is it? It also says that power loss from an easy break in could be up to 10% while the gain in power as a result of using his break in technique could be up 10%. Call me a skeptic - car makers have done full price + taxes buybacks when horsepower was 5% lower than advertised (RX-8) and it's well known that many engines are underrated in their actual power (335i N54).

The engine in your new car really isn't a brand new engine either - it was already tested at the factory, had its first oil change, driven on a dyno at the factory, on/off the transport, and then around the dealership. In some cases the car was driven to another dealer and test driven by other people. Some high performance cars are even driven hard on a track at the factory for quality control. If the first minutes of engine break in determine the rest of engine life and performance, you already missed it.

Engine break in goals are proper heat cycling, mating of parts, and stress reliving accomplished by incremental increases in varying rpm and load. You definitely don't want to baby the engine but you don't want to beat it hard either. The most important goals are avoiding excess engine wear, idling longer than you normally would, steady rpm, and high load on a cold engine."

How are you gonna say it's wrong when you don't fully understand what the process involves!

I've used this method on motorcycles that run twice the redline as most cars. The manual is there just in case you forgot how to drive a car or are a female driver!

Basically it's saying for the first 20 miles, keep the engine loaded and don't bog it, drain the oil to flush out the small fine metal shavings. If you don't have access to a dyno, you can do it on the street.

@ 11:22! They are tested prior to leaving the factory so keeping it under 4K is only there for liability reasons. Sorry to hurt your feelings but you are not the first one to drive you car. Be sure sure to watch the kid who tops your tank off, he'll drive how it's supposed to be driven.

Then it goes back to drafting for final drafts.

I know the engineers know what's best, but lawyers could care less and so do stock holders. Was there ever a problem with the first gen 1zz-Fe? Legally no, but they revised the piston design later because it had issues with burning oil due to bad ring design that was hit or miss. That was an engineering call to fix it, but if you ever ask Toyota if there was a problem they will tell you no.

I don't trust lawyers, so I won't trust "advice" on operating procedures. Most of the methods on hard break in call for constant high load, high gear accelerating and decelerating using no high rpms or brakes to slow down. Not exactly advice you want to give to a person who can barely handle a car beyond drivers ed. That's lawsuits material there.

So a hard break-in is in between what the manual suggest and being an idiot. Looks like I should be able to handle this.

I'll second Dizz1e's general stance. A freshly built motorcycle engine is not the same as a factory built car engine. Doing anything extra to try and seat rings "better" is unnecessary. Rings are seated at the factory in a modern car.

Fucking idiot = Anyone that chooses not to break in engine as specified by the manual.
