I'm not sure if anyone has suggested this before but it just came to me when I had certain questions about my car as its getting higher and higher to 200k.

What I mean is. there should be sections where people can post questions or post threads about what they have done to there car to prolong the life of there car at a certain mileage or maybe even post up problems people have ran into at a certain mileage. For example.

a section for 100k / 150k/ 200k.

Just a suggestion so its more easy for people to find what they need.

I'd love to see this thread get more activity, nearly a decade after.
Just did a compression test on the new-to-me k24a2 after 150,000miles.

K24A2 all stock from 06-08 TSX
tuned with kpro for the past 7 years, 120k miles in the previous owner's possession (swapped in with 30k miles, so 150k miles on the motor)
redline at 7600rpm
OCI every 5k, 5w30 conventional (previous owner mostly highway commuted), FRAM filters
Reported to burn 1/2 quart between OCI's
Type R headers/cat to EP3 stock cat back
RSX type S intake
410 RDX injectors
ktuned, dynoed at 220/170 @5200rpm
Most consumable parts (waterpump, alternator, starter, head gasket, timing chain tensioner) have been replaced in the past 2 years

Just compression tested this weekend, 160psi all 4 cylinders (killed the original k20a3 starter that was 220k miles old)
Not too concerned with the absolute numbers vs consistency due to discrepancy in equipment/methods

All healthy, looking to switch to 5w30 synthetic keeping the same 5,000mile OCI.
Probably also switching to a Purolator Pure One oil filter for more filtration capacity.

172,000 on an '06 5-speed A/T with NAV...mileage started getting worse at 150k...I've changed plugs, had valves adjusted and only burn premium gas (93 octane).

Mileage now only about 20 combined.

Car performs well. Idle is sometimes as high as 900 rpms...sometimes as low as 600. What's up with that?

Is it my EGR valve stuck open? Oxygen sensors bad? Evil spirits?

Any suggestions welcome...planning on making this my son's first ride. Car seems to run fine...no knocking or stalling. Highway mileage is about 30; but I used to get 42 at 65 mph when I first bought the car in '09 with less than 30k on the clock.

Any ideas or comments welcome...car's in great overall shape and is a keeper.

This is a very good, idea. I think there are some rules like: Change the oil about every 6000 miles. Keep the tire pressure accurate and have them rotated. Replace the air filter and the windshield wiper blades as needed; Use a high-mileage oil; Keep the outside clean; Do regular interior cleaning. I think this is pretty much all. To be honest I have seen many pretty and well-kept cars on the market, which also changed their mileage (to sell the car with a better price). Of course, I think it's a fraud and you should always pay attention to the vin and check it with Vingurus, but this fact shows it's actually possible to take care of the car so it remains "young" for longer.

I purchased my 2004 TSX with NAV new in 2003.
I presently have slightly over 308,000 miles and still going strong.
Only major issue has been control arms. Since then, only routine maintenance items.
No issues with timing chain either (still original).

I'm at 180K, replaced a few suspension parts due to crappy local roads but the engine is mostly original.

Almost all highway miles, so I've been doing 10K OCI with M1 5W30 high mileage. The 10K is nice because I rotate the tires while the cars on the jacks, but I'm not hard over on that. Thoughts? Is 10K too long, even with highway miles and good oil? Burns less than a quart.

Also thinking about whether I should do coolant parts and timing chain? Is this an interference engine?

My commute is long, don't want to break down out of town and being late to work costs me a lot of money (more than the car is worth).

Always maintained with OEM or better fluids, PO was my Dad.

I'm out here in the south suburbs of Mokena.
Seen plenty of crappy weather. As a real estate appraiser, my car has been through a lot of stop and go at properties throughout the years in addition to solid highway miles.
Still has the original shocks and struts (rides fine) along with muffler system. I've had no engine or trans work done (better not be jinxing myself!).
Sounds like you are really taking care of the car. As far as oil, I would recommend synthetic at this point (if you are not already adding that).
I use synthetic oil and change it every 8-10,000 miles (approximately).
I wouldn't worry about a break down with these cars.
They have great engines and transmissions and will certainly run for a long time with minimal repairs.
I would bring it in to a mechanic you trust and get his recommendations.
