Â* I think Pennzoil will gunk up your engine with paraffin deposits . I
use Castrol GTX in all my bikes and automobiles and change it every 5-6
thousand miles . Injected motors burn so much cleaner than carbed motors
that I think they can go longer between changes . I also use Wix filters
, best filter on the market IMO .

The great oil debate continues. The debate nowadays is how long between
changes.

If your vehicle requires 10w-30, then that's what you need to use. Brand
is a matter of preference, though, I prefer Pennzoil also. What matters
most is the grade.

Today's engines are well designed to drive farther than the 3000 mile
change, especially if using synthetic blends. Though, you didn't provide
vehicle info, I'll guess it as within 10 years old and the 5000 mile
change will not hurt it, thus, the 3000 surely won't hurt either. You're
just spending more money. It is recommended to follow the manufacturers
guide in the manual.

Follow the makers recommendations. I had a 1990 Camery and I think the
change was at 7500 miles. With the way I drive (mostly to work 15miles
each way) I put close to enough miles on the car I changed it twice a
year. Once at the anual state inspection and once 6 months later. Put
190,000 miles on it before getting a new car. Had no engine problems.

If you live in an area with dirt roads, drive only a mile or two each
time, or put the car to hard use , then the 3000 might be ok, but for
normal use I would go to atleast 5000 and maybe more if the manual says
so.

I don't put many miles on the cars now,so it is once a year when I get
it inspected that I have the oil and filter changed. I only had 3500 on
one car last year but had it serviced and oil changed.

Depends on driving conditions. Most cars can easily go 5000 or even
7500 miles on good oil. With synthetics some car makers are now 10,000
miles between changes.

If you drive short distances in the cold, go with the lower end.
otherwise 5000 or more is fine. Check your owner's manual.

I think you are wasting oil.
3000 miles is far too frequent.

Synthetic oils allow for twice the mileage between oil changes. My new
car uses it and change interval in the manual is 6,000 miles or every 6
months. The Castrol is synthetic and the Pennzoil is not so you are both
right except the mechanic has shortened the synthetic period. Mechanics
and service centers are looking for business and it is best to tell them
to follow the service manual.

I get the maintenance light every 5000 miles and change the oil then. I

It's a different animal but when a company I worked for went to Detroit
60 diesels they also started to do oil analysis. The protocol had been
12000 miles for oil and filters but it was lengthened to 20000. The shop
manager said they still weren't seeing significant degradation at 20000
but they needed to set some figure.

My Toyota manual calls for 5000 mile intervals and that's when the dash
light goes on. I assume Toyota is being conservative to cover all sorts
of use including the short trip people.

Neither depending on what sort of vehicle it is,
where you are and how you use that vehicle and
what the manufacturer recommends oil change
wise and how old the vehicle is.

I knew a few that worked at a WIX filter factory. They made filters for
several brands. Some were the same with a different paint job and some
were different internally.

My son worked for Lance ( a snack food company). They had a product
similar to Oreo cookies. When the Oreo company could not make enough
Oreos, Lance would make the cookies for them.

Lots of companies sell either the very same or similar items made at one
factory. Sometimes the product is the same , sometimes it is slightly
different and not the same quality.

But have you ever seen any actual performance tests that indicate the

and resultant demonstrably better engine performance in terms of fewer

12,000 km / 7500 miles / 6 months per my Kia manual.
I usually go ~ 9000 km. ... it's time to add and the oil is
looking dirty.
With my several old Taurus 3 litre cars - I'd change the oil
a little earlier than the manual recommendation ~ 7000 km
and it would still look new - not darkened.

Oil related engine failures are so rare it would be hard to really
make any kind of comparison. I know people, mostly single mom types,
who never change their oil and they end up throwing the car away for
things other than an engine failure. The oil looks like tar but it
still seems to be working.

None and I highly doubt a filter will cause major damage to an engine.
The exception is installing the wrong size filter and it comes off while
driving, thus, all oil poured out and the engine seized. Yes, I know
someone who had it happen.

If you use penzoil, change every 3000. Same with Quaker State.
Using a more highly refined oil with less parafins (Like Castrol GTX)
go 5000. Or use synthetic and go 10,000.

When was the last time you heard about an oil related engine failure,

Yiou haven't been reading the automotive press - pbviously.

EVERY ONE of the "coking" failures, whether Chrysler, VW, Toyota, or
who-ever is a "lubrication related failure" - and virtually NONE of
them occured on a vehicle following the "severe service" oil change
specification.

A single oil analysis means NOTHING. You need to do them at regular
intervals to determine trends. When does metal contamination start to
accellerate? What about acid levels?. As soon as you find out where
the metal contaminatio nstarts you know the oil SHOULD have been
changed earlier. Same with the acids, and other "bad" stuff.

Once you have the trends you adjust your changes accordingly and
reduce your monitoring to the later stages.

It's a different animal but when a company I worked for went to Detroit
60 diesels they also started to do oil analysis. The protocol had been
12000 miles for oil and filters but it was lengthened to 20000. The shop
manager said they still weren't seeing significant degradation at 20000
but they needed to set some figure.

Not nearly as muchas going 10000 when you SHOULD have changed it at
3 - and you end up replacing or rebuilding an engine -- - -

In fact 10K is the manufacturer recommendation with my Hyundai Getz.


12,000 km / 7500 miles / 6 months per my Kia manual.
I usually go ~ 9000 km. ... it's time to add and the oil is
looking dirty.

I didn't bother for 30K

With my several old Taurus 3 litre cars - I'd change the oil
a little earlier than the manual recommendation ~ 7000 km
and it would still look new - not darkened.

With my 73 Golf, I never bothered to change it at all in 45 years.

The only REAL problem with some filters is the filtration media
"splits" or comes loose from the endcaps - or drainback valves leak or
come apart - or cans leak - or the "base gaskets" don't properly seal
against the mount so they ALWAYS leak.

There ARE better quality filters than the base fram orange can
filters - the extraguard and synthetic Fram's being 2 of several.

There may be getter filters available than a WIX - but not many
applications where the "better" filter would have any effect under
normal use.

I'm going back to using Frams on my 13 year old Ranger with 368000km
on it - with synthetic oil changed twice a year. The oil AND filter
are still "clean" at these intervals (works out to about 6000km per
change) so why do I need anything "better"??

Oil related engine failures are so rare it would
be hard to really make any kind of comparison.

Yeah, the mechanic who did the rego check did say that
someone had blown up their Getz engine that way but it
wasnt clear if that was just running out of oil completely.

I did find mine had an odd clicking noise at idle at 3OK with
no oil or filter change that went away with an oil and filter
change. Didnt bother to check if it was the oil or the filter.

I know people, mostly single mom types, who never change
their oil and they end up throwing the car away for things
other than an engine failure.

I did that with my 73 Golf. Still have it but stopped using it
when the known windscreen leak produced a rusted floor
that meant it could no longer be registered and I couldnt
be arsed fixing it after 45 years.

The oil looks like tar

Mine didnt, but the Golf did use some oil.

but it still seems to be working.

Yeah, mine was working fine, no smoky exhaust or anything.

Same question as to changing oil at 3,000 vs 5,000. I didn't think any
new cars were less than 5K today. I'd like to see any studies that show
3K vs 5K or similar has any real effect on any engine problems in the
typical life of a car. Meaning, if you have a car, change the oil every
5K, get rid of it at 150K is there any evidence that a failure occurred
that would not have if you changed it at 3K? Or even if you keep the
car to 250K, does it really make a difference or is it just money down
the train to change it more often?

Castrol extended and change oil

Synthetic oils allow for twice the mileage between oil changes. My new
car uses it and change interval in the manual is 6,000 miles or every 6
months. The Castrol is synthetic and the Pennzoil is not so you are both
right except the mechanic has shortened the synthetic period. Mechanics
and service centers are looking for business and it is best to tell them
to follow the service manual.

Doesn't sound like 2x to me. Cars were at 5K intervals with regular oil.
Even BMW went to 15K with synthetic, thought they must have seen some
problems because they backed off to 10K. If you only get 6K on synthetic,
something doesn't sound right.

My car is 7500 miles for normal driving. The warranty is for 100,000
miles. They would not offer the warranty if they did not think it would
make it that far.

I imagine testing of some sort was done to conclude that
