Integra Type S driving Styles with Breakin Period

[cipher]

Mine is, and will continue being, a daily driver. I keep it garaged at home and garaged at work, but it gets driven almost every day in the snow, ice, rain, whatever. It's a car, not a 'special snowflake' to be babied. Of course it's a wonderful car and I don't beat the crap out of it like I did with some of my past vehicles.

I bought mine brand new with 22 miles on the odometer. I reached 600 miles last weekend and gave it the first break-in oil change at about 608. Typically these can be done from 500 to 1k, but the timing was perfect for me at 600 since I'm heading down to DC/Maryland this weekend with the wife, which will add another ~500 or so miles.

I'm a very low mileage driver. Everything in my university town is rather close by, within a 10 mile radius. I'm just under 5k a year. My old 2011 vehicle had 73k miles before I sold it this year.

When I was breaking it in, I made sure to vary the speed a lot. I avoided staying in the same gear or at the same RPM on the highway when bringing it home for the first time from ~200 miles away. I didn't red-line it at all until about 400 miles, and even then probably red-lined it about 5 or 6 times during the first 600 miles. I couldn't resist the temptation and seeing the RPM gauge screen flash red for the rev limit shift indicator. After all, manufacturers take these engines to ~80% of red-line for factory break-in before they're paired with a chassis.

And yes, I drove it in 30, 40, 50, and 60 degree weather these past several weeks.

I only run it wide open for several seconds at a time, then bring it right back down to drive it fairly easy again. I adhere to the more important aspects: don't let it idle for extended periods of time, don't drive it at the same RPM for too long, and don't take it on the track or push it hard for any considerable length of time.

If your brand new car has more than may be 5 miles on the odometer, then it has been test driven by an unknown number of potential buyers at the dealership. You can't be 100% certain that none of them red-lined or really pounced on the throttle during those test drives. So why worry too much each time you get a bit too feisty with it? Just be reasonable and enjoy it during the break-in period.

Engines are not broken at the factory. They are checked for function and leaks. Do you think factories have the time to break in hundreds if not thousands of engines?

Yes, they do have time for that. They are bench tested and have an actual break-in at the factory, up to 80% redline and 150 mile equivalent. But this doesn't negate the need to observe a break in period for the first owner.

From Acura, for the last gen NSX as an example (source):

In-house Validation: To ensure the pristine condition of NSX, each vehicle is performance-validated through a sophisticated series of measures within the walls of PMC, and its engine is bench tested to the equivalent of 150 break-in miles at the company's Anna, Ohio, engine facility, such that every NSX is track-ready without ever having been driven on the street.

Our ITS engines are manufactured in Anna, Ohio, and the car assembled in Marysville, Ohio. So it's safe to assume that the procedures they do for the NC1 engine at the exact same facility up until 2022 are somewhat similar to the procedures they perform for our K20 engine.

So yes, may be around 150 miles equivalent of "break-in" at the factory even if the engine needs additional break-in once it's purchased.

Just hit 600 miles and ive notice my clutch feels soft. Ever since I got the car its been raining and cold. But recently the its been getting warm. Anyone notice a change in clutch feel depending on the temperature?

I do notice the clutch soften up a bit after it warms up, but it's not a huge difference. Also shifting is a bit more notchy when the transmission/synchro gears are cold.

That's for the NSX, though...

Do you believe they're rolling accords down a line and running them on a load engine dyno for 150 miles?

Brother worked in the Ohio plant. They absolutely didn’t do that shit for the type s. They barely did it for the nsx

apparently as long as it hit 4k rpm and sounded ok holding it for a minute or two. It was good to go.

That's good to know. So just marketing BS?

He made it sound like it depended who was in the plant. If Someone important was there, they’d definitely run the nsx's longer.

OK, that's fair. 2min at 4k in top gear (about 110mph) = 3.67mi. Car delivers with 6mi, and dealer boys make up the other few in parking lot. I'd call that broken in. Good enough for me . Send it! that's what warranties are for

So you think that a mass produced engine is given the same treatment as limited edition engine? How many dynos do you think they have at Marysville? I think your assumption is unrealistic.

Loss of compression or oil burning at 80,000 is not covered by any warranty.
