Tom,

As I said, if I thought the additives were harmless, I might use some of the
additives and as inexpensive insurance. But, I don't change my oil every
3,000 miles because
of the recommendations of the oil companies or mechanics who profit from me
changing my oil every 3000 miles. I change my oil every 3000 miles because
of the recommendations of the auto manufacturers, and ALL auto experts I can
find recommend changing the oil every 3000 miles, and these experts do not
profit from me changing my oil every 3000 miles. I have had some friends
who are mechanical engineers who told me they always change their oil every
3000 miles. I had one who used Mobil 1, and he said he always changed the
filter every 3000 miles, even though he would go 12-15,000 between oil
changes. I understand they now make filters that are supposed to last the
full 15 m miles, but this was 10 yrs ago.

I typed in "how often should I change my oil" in Google, universally, unless
you drive in ideal conditions, which I do not, all of the experts (who do
not
profit from my oil change in any manner) agree that it is best to change
your
oil every 3000 miles ". As Yahoo Auto stated: " if frequent short trips
(less than 10 miles, especially during cold weather), stop-and-go city
traffic driving, driving in dusty conditions (gravel roads, etc.), and
driving at sustained highway speeds during hot weather. For this type of
driving, which is actually "severe service: driving, the recommendation is
to change the oil every 3,000 miles or six months."

So I might be getting fooled and suckered, because heck what do I know, but
I look at it as inexpensive insurance.

How often do you change your oil?

Tom,
Normally in the 3,000 - 4,000 range.

So you are suspicious of claims of oil additives, but buy into the oil
company hype about 3,000 mile oil changes.

Interesting.

Later,

Tom
