My truck has a built in feature that puts a message up on the dash
readout when it's time to change oil. The owners manual says that the
message is based on a lot of things, including length of trips,
temperature, and driving habits, and to change oil when I get the
message, or at 7000 miles, whichever is sooner. The message typically
pops up at around 6000-7500 miles.

The factory dealer's service department still puts on the 3000 mile
sticker, though.

The manual for our '02 Chrysler 300M has two maintenance schedules:
7500-mile oil changes for "normal" driving, 3000 miles when trips are
mostly short.

We've always aimed at 3000-mile oil changes, but we don't get too
concerned if the intervals are somewhat longer. I don't think we've ever
reached 4000 miles between changes.

change at 7000 to 7500 though, just like the book says. Maybe in mid winter
I'll go earlier, but at least half my driving is highway and 25+ miles

Because if you don't change the oil more frequently if you
do city/in-town driving only consisting of short trips where
the engine oil doesn't get up to operating temperature for
a good length of time, it breaks down much faster and
does not do its job properly...

Not only does engine oil lubricate the engine's moving
parts, it also acts as a medium to transmit heat from
parts of the engine which are not near the coolant
tubes...

It has nothing to do with the engine oil change military
industrial complex wanting to stiff consumers out of
money for more frequent oil changes at all... It is
whether you want to have to pay for costly engine
repairs or even replacement because you had
broken down oil in your engine for about 1/2 it's
operating life because you went twice as long
between changes given your type of driving and
any environmental conditions... You would want
to change the oil at the 3,000 mile frequency if
your driving environment is primarily desert
or beach landscapes as you would want to
rid the engine of any grit that gets past the
air intake filter and not allow it to remain inside
the engine to wet sand the parts and destroy
things like oil seals and piston rings...

I drive so little any more, I do it as much by time as miles- about
every 8-10 months works out to every 4-5 k miles. Of course, the current
two cars are the first ones where I am not adding a quart every month or
so (knock on wood)- if you have a car that leaks or burns and keep
adding fresh oil, you can stretch it a bit. 3k miles is 'because that is
the way we have always done it' and a profit center, IMHO. Even Click
and Clack say 3k is too often, with modern oil and engine systems, and
unleaded gas. I do make sure to drive long enough and fast enough to get
the engines fully heated up, at least once a week.

B S While you are correct for severe service, the oil change places just
put that 3000 mile sticker on the car as they have been for 50 years. Under
normal conditions, you can easily go 5000 to 7500 miles and not do any
damage. Oils and engines have changed since 1960. I remember it was common
to do rings and bearings on an engine at 50,000 miles. Those days are long
gone.

Always changed oil on recommended schedule, not 3000 miles.
Result NEVER had an engine problem, let alone failure, due to wear, or
heat. Used car for commuting and around town. Oh yeah my experience is
limited since I am only 71. Yes I would have changed oil more in tough
environments, but most folks do not have that issue so most folks can
ignore 3,000 mile BS.

Manual will probably say change in so many miles/months. As a retiree
who drives less than half the suggested miles in the time alloted, I
usually change mine every 3,000 miles or 6 months.
I recently had a situation where I asked for reimbursement of a known
problem after the warranty period and all service records outside the
dealer were requested. I don't save receipts but I do keep a service
log book and my claim was allowed.

I was given 3 years bumper to bumper when I bought it, so the oil
changes have been free. I plan on waiting until around 7000 km (about
1000 km before my B2B expires) to have it change before relieving on the
oil life sensor again.

Our '02 Chrysler 300M tells me when an oil change is due, but the
interval can be set by the user for either 3000 miles or 7,500 miles. We
always have it set for 3000.

Ok, now I have a different result. The last time I got my oil
changed at Walmart they put a 3750 mile sticker on. That is
the factory recommended interval for regular driving. If the
driving is mostly highway it can go to 7500 miles. The car
is a 2007 Nissan.

Todya's engine and oil is more advanced compared to olden days. Like my
neighbors just delivered new BMW does not even have a dip stick. After
10K km oil change I never saw old oil coming out has color change or any

I just looked at mine (97 Lumina sedan) and it has "Short trip/city"
and "Long trip/highway" maintenance schedules.
It's a pretty lame format, showing pages for odometer increments.
The short trip/city has 3000 miles or 3 months, whichever first.
The long trip/highway has 7500 mile or 12 months, whichever first.
Darn, this manual has pages stuck together because my basement
flooded, and I'm throwing it away. But Chevy has a downloadable pdf
file and I just downloaded that. That's a new one to me.
I pasted what they say below.
Since most of the miles we put on it are my wife's 6 miles to work and
6 back, it comes under the short schedule.
And that's what I do, except it's sometimes closer to 4000 miles and
that 3 month stuff is crazy. Forget about that.
Maybe 6 months given out usage pattern.
Once a year we do a trip about 3000 miles and I usually change it just
before we go, along with doing any other maintenance I deem necessary.
That's when I check hoses, antifreeze, etc.
Not too long after we get back oil gets changed again.
I don't worry about going 500 over.

Short Trip
Every 3,000 Miles (5 000 km): Engine Oil and Filter

Follow the Short TripKity Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailero r use a carrier on topo f
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercia1 application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.

Long Trip
Every 7,500 Miles (12 500 km): Engine Oil and Filter
Change (or every 12 months, whichever occurs first).
Follow this maintenance schedule only if none of the
conditions from theS hort TripKity Maintenance
Schedule is true. Do not use this schedule if the vehicle
is used for trailer towing, driveni n a dusty area or used
off paved roads. Use the ShoTrtr ipKity schedule for
these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions causes engine oil to break
down slower.

For the past 4 years or so, my driving has been mostly moving the car
for street cleaning, and to the market up the street every week or so.

I sometimes won't go through more than a couple of complete warm up
cycle between changes...

As a result, I'm now changing oil by calendar month... do it every 90
days, ...even set up a Google calendar reminder.

Got 22 years out of my old 87 Accord... changed it's oil (Valvoline
10-40) every 3000... whenever I had the valve cover off for adjustments,
it looked like the day it was built. It was the rest of the car that
became an issue...

can't change my own oil. (The filter is inaccessible without ramps or being

To get the oil to "operating temperature" generally takes 10 or more

driving, if it has done a lot of short trips over a period of weeks
before.

Follow the $$.

If the manual says 7500 why do anything else?

Because if you don't change the oil more frequently if you
do city/in-town driving only consisting of short trips where
the engine oil doesn't get up to operating temperature for
a good length of time, it breaks down much faster and
does not do its job properly...

Not only does engine oil lubricate the engine's moving
parts, it also acts as a medium to transmit heat from
parts of the engine which are not near the coolant
tubes...

It has nothing to do with the engine oil change military
industrial complex wanting to stiff consumers out of
money for more frequent oil changes at all...

Although Ed already said it, I want to say bull****! too.

And just like Ed said, I don't at all disagree with your other comments.

The people that work at Jerky Lube, at all levels, work there because
they have no skills. You really can't believe their advice is better than
the manufacturing design engineers. If you do then you must be buying
into this **** purging stuff being hawked on TV - change yor ****/oil
before it needs it.

It is
whether you want to have to pay for costly engine
repairs or even replacement because you had
broken down oil in your engine for about 1/2 it's
operating life because you went twice as long
between changes given your type of driving and
any environmental conditions... You would want
to change the oil at the 3,000 mile frequency if
your driving environment is primarily desert
or beach landscapes as you would want to
rid the engine of any grit that gets past the
air intake filter and not allow it to remain inside
the engine to wet sand the parts and destroy
things like oil seals and piston rings...
