View Full Version : Can Honda track OCIs?

My MMS is down to 5% now, so I was wondering if Honda can see if the car goes "over" its "oil life" and use that info to say doing so damaged the engine (if warranty work is needed in future)? I doubt Honda can track it but I just wanted to make sure, since I'm running Amsoil with a K&N filter (both rated for FAR longer than Honda's MMS calculates based on their dyno and filter) and would rather wait til either this coming weekend or the weekend after so I'm not crawling under the car in sub-zero weather and snow (probably go over Honda's limit by around 1000-1500km)

I doubt honda can track it... that said if you have a problem I believe it is on you the owner to provide documentation that you serviced the car properly. Im not sure how this works with maintenance minder though since the intervals are not "set". I would imagine honda gives you some leeway like 7500 miles but I would not count on it...

Hmm well I keep all my receipts for oil and filter, so I have some proof I actually did the work instead of just resetting the MM system. Actually for stuff like the timing belt I'm probably going to go off the 03-05 schedule since I want to make sure that gets done sooner rather than later (basically do it either on the 03-05 schedule or MMS, whichever comes up first).

Guess I'll probably let it slide a little longer. Running a 7500-8000km OIC on pure synth seems like a bit of a waste anyhow (bottle says 20,000km-25,000km, but I'd never trust it that long).

I have no doubt about the oil lasting... its the filter thats going to make me change my oil.... My last change I ended up with one of those crappy fram honda brand filters, next change im going to Wix.

RIght now my MM is saying 30% and I have gone about 4.3k so far... I am thinking i'll take mine down to 5%. Guessing 6kish?

If you're concerned that Honda could detect, through the MM system, that you went beyond the recommended OCI interval then simply reset the MM system when it tells you to. How would Honda know that you didn't change the oil at that time?

In the unlikely event that Honda would deny warranty coverage due to not changing the oil at the proper interval, they would also have to demonstrate that not changing the oil caused the damage.

Having documented oil analysis on hand demonstrating that you can safely go beyond standard OCI's with products like Amsoil would also mitigate any concerns.

If it were a GM with Onstar I wouldn't doubt it one bit. As far as the Honda goes.......nah.

Excellent point. It gets scary when the vehicle has an uplink capability (i.e. vehicle diagnostics).:paranoid:

NAH! It's entirely entertaining.

The day I went with my Aunt to get her Saab 9-3 Conv. we took some backroads pretty hard in acceleration, cornering and braking. Onstar kept saying "Have you just been in an accident?". - Car and Driver experienced this with a Malibu they tested awhile back too. Good times...:yes::lmao:

I don't know about that. My friend's new Chevy truck can tell him online the temp in each cylinder, the octane of fuel he's using, and other things I didn't think possible.......a little spooky.

My oil filter should be fine...when looking up filters I decided to go with the K&N because its not a standard paper filter (it alone is rated to around 20,000km too I think, but I'd never trust it that long for sure). Its too bad I couldn't find a wix or equiv here in Canada...the K&Ns aren't cheap, but everything else local is made by FRAM (and shipping and duty kinda ruin going across the border for filters).

As for just resetting the MMS, I'm always hesitant in doing that since wouldn't that throw off the timing for the other maintenances? I mean, say I reset it to 100% now, and in a week change the oil and reset it to 100% again...doesn't it calculate the timing for changing the timing belt, coolant, transmission fluid, etc all based on the number of oil changes?

I guess I wasn't clear about resetting the MM.

Reset the MM when the system says to perform service. If you want to change the oil at that time, then do it as well as perform other services the MM indicates.

If you choose to not change the oil when the MM is reset, change your oil when you decide but do not reset the MM.

Let the MM "do it's thing" and you do yours.

Well either way, the light came on while i was out with someone tonight...so nothing I can do now LOL. Will just keep driving it until the weekend with the light on, then change the oil out on either saturday or sunday when I have time.

I'll ask....:dunno: I do know they can find out what speed & conditions of the car when it throws codes by hooking it up! (until the code is cleared). It's caught a few people unaware when they claimed they didn't miss that gear that made it severely over rev & blow up!:yes:

Thanks Princess. My guess though is if it does "log", then its similar to what you said about when the ECU throws a code...so in other words it might be logging atm, but once I change the oil and reset MMS this weekend, it will clear that log since the "oil life" code has been cleared. Maybe it keeps it in memory until the next change, but I'm just not sure if it flags the car of going past a change...so Honda can use that to their advantage if there are issues in the future (since a oil analysis won't prove much if the oil was left in for say 30,000 miles then changed out at 5,000 miles the next two times).

It is scary how much an ECU is capable of these days...oneStar is just one more reason why I don't like GM products (insert 1984 quote here...:paranoid:)

I think you're overestimating the capabilitites of the maintenance minder system.

I asked...the MM is a separate system & doesn't get recorded like the codes.

GM onStar- bet your life the oil % is being monitered. Wife gets an email from GM when the Tahoe goes to 20% left. I just change it every 5K with PP 5-30 and PP filter
