Any 3G owners have or coming close to 500k miles..?

How does is run? What parts wore out besides for regular maintenance items?

 

i'm going to venture to say that if you take care of the car, the car will head north of 500k.

this means replacing the small stuff that goes out.
starter, alternator, 02 sensors, timing belts and water pumps, drive belts and pulleys, suspension components (shocks, bushings, etc), fuel pump (if you run it dry and with bad gas) HFL (Hands free link), Navi, radio, et-fucking-cetra.


the point of maintenance is to replace a failing part when it happens.....
so, that when you do hit 500k miles, it's not going to be all at once...


too long; didnt read?
just maintain the car and fix whatever is broken and she will last a very long time

 

Besides the components mentioned above good ring seal won't last that long and neither will any of the mains, but an engine rebuild should be expected to get to that kind of mileage unless you don't mind adding a quart of oil every 1k miles. Otherwise it's a Honda, it will continue to run for as long as you do regular maintenance and service end-of-life parts. I've had a Honda distributor cap last over 200,000 miles, their stuff is virtually bulletproof.

 

I'm at 200K so far I've replaced:

1 AT Transmission
4 shocks
3 sets of brake pads
1 set of rotors
12+ quarts of ATF
20+ quarts of oil
10+ sets of wiper blades
1 wiper motor
6 spark plugs
105K Service
Valve Adjustment
Starter
1 set of lower control arm bushings
1 set of Hood struts
5 bottles of Power Steering fluid

Edit: 6/24/15, 1 new driver seatbelt buckle covered by acura

 

Don't see why one couldn't.. Like mentioned, it's a Homda after all. There are 90s vintage Hondas and Acuras that have gone that far on original engines etc

 

i'm at 214000

 

I know this is 3rd gen forum but my 03 type s has 345k on original J32A2 engine and has had three 105k services. I change my oil at 20-25k intervals and the oil level is still close to the upper dot.

I know the 3rd gen engines are very similar and should be able to go past 500k without any serious issues. I know I will get it out of mine.

 

^^^^ yup. I'm at 199K and currently putting over 30K/year on my 04. I'll be there (500K) in 10 years

I think mmade (or something like that) had over 300K on his 3G over a year ago before he sold it.

 

any car can last up to 500k miles if you keep all the maint and not itching for a new car.

 

yup! I had a 02 type s sold it at 300k and sold it to my buddy it has around 350k now

 

I should add that at 199K I still do not have to add oil between oil changes. My MID oil change interval is ~8,000 miles and the oil level is down 1/2 quart at most at change time

 

clearly you're not driving it hard enough

 

engine? sure

trans on early ones, nope unless it is a 6mt

 

25k between oil changes ???

 

How many transmissions have you been through?

 

The engine is the last thing I would worry about making it 500k. Even the stock 5at can do it.

Any 3G that hits 500k in the next few years will have to had been mostly freeway driven. While going steady state down the freeway in top gear you're covering much more distance per engine revolution. You're under light load. Temps are steady, far fewer warm up cycles for a given mileage. The transmission is not shifting. The torque converter is locked. If the trans isn't shifting, the clutches aren't wearing. If the converter is locked, very little heat is being produced. An engine that's driven purely on the freeway will have 6x fewer revolutions on it. A transmission that's driven almost purely on the freeway will have literally 1000x fewer shifts on it.

The cv axles will live most of their life going mostly straight where wear is virtually nonexistent. The power steering is mostly freewheeling. The brakes are rarely being used.

I would equate 500k of freeway driving to about 100k of city driving in terms of wear. It's probably even more biased toward freeway driving in reality. I say it's completely possible with only normal wear and tear maintenance.

 

How do you figure that?

I figure it's more like 2.5x fewer revolutions:

City driving, avg of 25 mph at 2000 rpm = 4800 revs per mile

Highway driving, avg of 75mph at 2600 rpm (6MT) = 2080 revs per mile.

 

Idle. 700rpm with the car stationary but in gear with some load.

While it's easy to accumulate several minutes of idle time at a light or in a drive through with every drive, the engine has spun a few thousand rpm while the car sits still which would be several miles on the freeway.

Torque converter slip giving considerably more rpm than the gear ratio would otherwise have while it's locked going down the freeway.

Videos of my driving in the city to get real averages.

First gear take off with an 1,800rpm stall speed starting at 0mph until the shift point around 3,000rpm at ~20mph. No less than 2,000rpm on the shifts due to converter slip.

Revolutions per mile for each gear and time spent in each gear.

Deceleration as the 5at downshifts to keep rpms up and stay in fuel cut.

The list goes on and on but 6x is what I came up with after measuring and calculating.

Not to mention considerably less load on average on the freeway for less wear and tear.

 

I think for city driving, 25 mph average is a pretty fair assumption. So in an hour of city driving, assume you spend 1/3 of that (20 minutes) in idle (e.g., at stop lights, in traffic). So that's 20 x 700rpms = 14,000 revolutions.

Then let's assume the other 40 minutes is spent driving at various speeds with an average rpm of 2000 (which I think is probably on the low side). So that's 40 x 2000 rpms = 80,000 revolutions.

So at an average of 25 mph that comes to 3760 revs per mile for average city driving, vs 2080 revs per mile for highway driving, not anywhere close to 6:1...

Or look at it another way: Highway driving is set speed/rpm, so it's a fairly firm figure at 2080 revs per mile. So if city driving is 6x that, then it would have to be 12,840 revs per mile. If we assume most folks average 25 mph in city driving, then that would mean city driving would have to average 5200 rpm....

 

It's doable with Amsoil. My brother in law had a 2008 TL that he bought almost new and sold it with 115k miles and he changed his oil every 25K and that thing ran like a champ. His dad currently has a 2007 Toyota Sienna that he bought with 10k miles on it and currently has over 250K miles again changes oil every 25k and still runs like a champ and he puts that Sienna to work too.

 

I average 13mph in city driving, pure city driving. I'll show you the math when I get the time. It's 6:1 on average.

 

It's possible with many oils. The problem is usually not the oil holding up. The problem is usually the contaminate load. The main purpose of dumping the oil is to get rid of the combustion byproducts that accumulate in the oil. As long as the additive package and TBN/TAN don't drop too far the oil is fine for many more miles than we actually use it. I don't like going too far because I don't want the acids, water, wear metals, and silicone/crap building up too much. Plus, some oils oxidize over time, some thicken, and many permanently sheer.


25k of pure freeway use isn't too terrible. 25k of short trip city use would be horrible.

 

Yea either way I wouldn't feel comfortable going 25k between oil changes. 10K is about my limit even tho i usually change it about 5-7,500K depending on my driving.

 

I've actually had my MID take me to almost 10k before. It was literally all freeway driving. I was commuting 210 miles a day. My office was at the end of the on/off ramp. My house was just a few lights from the freeway. It was 1:45 of drive time, wait 8 hours and and another 1:45 drive time and very few short trips in between. It's also wanted me to change it near 3,000 miles with my current commute. It's 1.5 miles to work. About 2-5 minutes of runtime in the morning, less than 10 minutes of runtime in the afternoon. I take my new car on any weekend adventures. It's been kind of cool to see how the MID handles each extreme. I actually drive my car the 39 miles to work instead of using the company car every 2-3 weeks to get the oil up to temp and burn off condensation.


Your change interval is a great all around mileage for most conditions on a decent oil. I've tried the SSO oil that your brother probably used. It's a good oil.

 

I hope to get 200K out of my '07 with very little maintenance. She just crossed 83K.

 

I just rebuilt my top end at 155k I hope to see 500k

 

What happened?

 

if his user name gives any indication....


i bet he pulled a justin

 

I want to unread this. All I can think of is seized motors

 

As long as the level is checked from time to time, the worst thing that's going to happen is a little varnish or sludge given enough time. With a really great oil those two things are greatly reduced and then all you have to worry about is the contaminates being circulated around for 25k. I guess what I'm trying to say is there won't be any catastrophic failures related to lubrication but you might get some less than ideal results which might be fine depending on your goals.

 

I'm at 235,000 with original clutch. 95% of my driving is highway. I have a 2005 6mt.
