OT Who changes their motor oil at 3000 miles?

[Steve B]

Just to be fair here, it should be noted that most jobs "created" are in the government sector to ease the three day workload of existing government workers.

You still use air? For about $70 you can have them nitrogen filled.

Yes. My dipstick still works but I don't use it as often.

Not necessary to get your back up, Steve. You claim good results at a

3000 mile interval, and no one doubts that. Many if not most posts here are claming similar results at longer intervals. This is consistent with guidance from many if not most auto manufacturers. So when you make the declarative statement:

it begs to be challenged.

By the way, this yuppie has never sold or traded a car before

140-160K.

Certainly, having just had our 40th anniversary, I can attest that dipstick usage changes over 40 years. ;-)

[Ed Pawlowski]

But the last use was still as good as the first!

[Congoleum Breckenridge]

The removal of lead from Gasoline helped both oil life and exhaust system life. Plus, a hot catalytic converter upstream helps also.

Oh, we do have "policies."

For example, Canada just completed a "Free Trade" agreement with Columbia. Columbia will now buy Canadian wheat at 15% less than American. The current administration's "policy" is to NOT submit the Columbian Free Trade Treaty to the Senate.

I'm not sure what you mean by "industrial policy." If you mean a government-directed plan to favor some industries and control the direction of development, Japan tried that and it failed miserably. Authoritarian governments have also tried setting quotas and goals (i.e. Soviet Five-Year Plans and the like) which have also failed miserably. Not to be discouraged, OUR government is meddling in the same thing with ethanol subsidies and grants for "clean energy" development.

I think it was a beer that used that tag line. I know Schafer is the one beer to have when you're having more than one.

[Steve Barker]

if you actually READ the owners manual, you'll see they suggest 3,000 mile intervals for sever service. Most all of our daily driving will fall into that category. I don't trade vehicles at all, i junk them. And I change oil at 3,000 miles. Many of my vehicles have gone beyond

300,000 miles and don't use ANY oil. ('cept that bigblock chevy, LOL)

[Steve Barker]

exactly.

[Steve Barker]

Well said. And correct.

[Steve Barker]

Nothing has changed. And i'd like to see the engine builder that recommends the 75,000 mile oil changes.

[Steve Barker]

They are not stainless, they are aluminized steel. Stainless is a terrible material for exhaust systems. Cracks too easy.

[Steve Barker]

the manuals already say 3,000 mi under sever service. 95% of people fit this category.

[Harry K]

Hmmm...seems I tied that to the wrong person. I thought I was replying to someone saying it didn't need to be changed for some ungodly number of miles. My bad.

Doubt it. Just thinking about my neighbors, of nine cars I know of. three fit into the severe category. Of ten cars at work, two definitely do, two are questionable. While my informal survey is not scientific, it is a far cry from the 95% figure you use.

Fact is, no one can give an absolute number of miles for large groups of people. The best way, of course, would be oil testing. Some cars to have some soft of algorithm that does give you a time to change based on driving habits, miles, etc. If the people that are covering the warranty give higher miles, I'd say they are rather sure of the numbers.

[ed_h]

Now there is another claim that's going to need some backup.

I think I'm a pretty typical driver, and the system built into my car usually says it's time to change at around 7000 miles.

There may not be a precise definition of "severe service", but I'd be skeptical of any definition that came from anyone selling oil or filters.
