A recent addition to my 'FLEET' is a 08 Malibu.
It has a oil change monitor. It reads in oil life remaining expressed as percentage. For example 48% OIL LIFE REMAINING.
It bases its calculations on, number of startups, how long run, ambient temp at startup, miles travelled, and time measured in days.
Lotta mumbo jumbo and I'm not comfortable when the car has 6000 miles on the oil and it still says 30% remaining.
So, I kinda wish it was like the Jeep inasmuch as you can preload your change intervals, and it helps you remember.
Instead, I still have to write down my last change mileage, cause I'm sure not leaving oil in there for 9000 miles. (Manual says can go up to 12 months before alert)
If it's running Mobil 1, it probably can. We had a C5 Corvette and the oil change was "when the computer said so" or 1 year, whichever came first. I think there was some ridiculous number of miles that was the max. 'vettes sometimes see a lot of garage time (mine was stored during the winter months) so the year seemed reasonable to me. Chevy stands behind the recommendation.
I was a little surprised on the Commander to see that it needs plugs at, I think, 30,000 miles. Newer vehicles have pretty close tolerances, better air/fuel mixtures, not as much blow by as in the old days, less to foul things up, etc. I don't have the manual out, but as I recall the '08 Commander 3.7 is rated at 6,000 miles between oil changes. Considering that Chrysler is recommending the interval and also guaranteeing the internal motor bits and pieces for the life of the vehicle, it seems reasonable to me that 6,000 miles should be good.
I was a little surprised when the dash warning came on this morning.
I know a lot of folks swear by the 3,000 mile marker - but when I started driving in 1966 the recommended interval was...3,000 miles. Surely to goodness there has been some
improvement in oils and engines. (Don't see too many folks loading up with 10W40 anymore
). So I happily go with the maintenance schedule of whatever is in the owner's manual and so far I've not had any oil related issues.
Except that it's pricey as the dickens when it's purchased in crude form by the barrel.
I've no issue with others who feel safer changing at 3,000 miles - but 2,500 seems a little...premature...on a brand new Jeep.
I gotta go read the manual on setting the meter on this thing...
Thanks for everyone's input - post a note at work and have definitive answers by the time ya get home. Ya have to love this place!
