I copied it from the manual you linked to.

Yeah, those Goddamned Subarus. Either way, you're wrong.

So you're using a manual from a car built in 1981. And you left out the next paragraph:
"However, when starting in extremely cold weather it is a good idea to allow the engine to run at fast idle for about 30 seconds before getting underway; this precaution ensures adequate lubrication."

Why didn't you add that?

Right. Because Cold, and Extreme cold aren't cold and cold. When it gets below 19 degrees, my year old car has difficulty switching in and out of gears unless I let everything warm up. But, I guess that doesn't count unless I'm in North Dakota.

Canadian Prairie? I live in the mountains. We probably don't get as much snow, but half the places in this area cannot be reached in snowy conditions without 4WD. Your "normal" must be flat, suburban driving.

You're right. If you have 2 V8's of which one is boosted and one is not, you can drop the power on the turbo motor on the bottom end so it gets better mileage, but it won't sustain that throughout higher RPMs or spirited driving. You'd get better mileage with the turbo vehicle if it had a lower horsepower bottom…

You mean once you get over 6000 RPM, the engine doesn't just exponentially suck more air to go faster? What are these turbo things and why do we have them? Hmm. lol

That's physics for you. A vehicle weighing 5000lbs with snow tires would have quite a bit more traction than a 2800lb vehicle on with smaller snow tires.... in a relative sense.

But... did you read the quote? It's incorrect.

Too many maths.

They're stress testing it. Not idle testing it. If you want to do something that exceeds normal wear, you abuse it... like.... covering it in snow and start it up cold. Otherwise, idling it isn't providing any stress.

Do you have links or copies of that manual? I'd be interested in seeing it.

Here's your solution.

The A/F Cycle takes at least 30 seconds to complete. Anyone with an A/F gauge knows this, but they also aren't stupid enough to believe this FB nonsense.

Subaru disagrees with facebook posts... for years. http://subaruonlineparts.com/subaru-impreza…

I've seen this happen to people who have traction control turned on. I actually went into someone's yard once because it cut the throttle when I gassed it to pull out of a turn.

Because internet means nobody is right.

There's no money to be made in telling what the issues are. My Jeep has a series of things to do in order to get codes to pop up on the display, but you still have to look them up. I'd imagine to the average driver, their first reaction is to make an appointment at the local garage or place where they bought the…

....Subarus are an anomaly with this theory. They have the usual issues, but regardless if they have regular check-ups or not, you still see a 300k mile beater on the road sounding like a crop duster, covered in mud and never discarded.
