Re: Mobile 1 Extended Performance
Unfortunately my mind doesn't track straight all the time these days,
too many pills. Not sure what set me off on that one....

Hi Campbell,
You use the word "synthetic" as if it's not a petroleum product.

Re: Mobile 1 Extended Performance
Hi Campbell,
The main claim of the new Mobil One Extended Performance is the longer
15,000 mile service interval. Looks like they're trying to answer to
AMSOIL's extended service claims (35,000 miles!):
http://www.worldsbestoil.ca/0w30-ams...ne-engines.php
As for the Castrol Syntec, be careful. Apparently the US-made version is
not a 'true' synthetic and is a relatively poor performer. Look for the
imported Castrol Syntec with 'Made in Germany' printed on the bottle.
Myself, I change the non-synthetic 5W-30 in my high-mileage 4.0L every
3K miles. The engine runs great and it doesn't burn oil.

Re: Mobile 1 Extended Performance
My $0.000002...
I have had the opportunity to study quite a lot of closely held
oil/filter/wear information. Here's the basics:
Keeping oil clean is the primary goal. What is 'clean'? The primary
component of 'clean' is particulate loading and particulate size. Your
normal paper oil filter filters out most of the particulates 25 microns and
larger. That's 0.001 inches. The smaller chunks keep circulating. Think
about a low viscosity slurry of oil and rubbing compound.
As the total particulate loading is reduced and the maximum size is reduced
by more efficient filtration, the total amount of component wear starts
dropping rapidly. Cutting the load and maximum size of particulates in half
results cutting the total wear by a square root function. There is also the
distinct probability that any single element pleated paper filter will be
leaking unfiltered oil (blow-through) by 3K-5K miles.
The other thing that happens is that the additives and stabilizers in the
oil are depleted and there is an associated breakdown of the polymer
molecules. However, I am aware of an experiment that ran petroleum oil with
double efficiency filtration that ran 30K miles while maintaining the oil
within all oil testing specifications.
Another factor is the contamination of oil with other liquids - fuel or
coolant - that serves to reduce viscosity and upset/reduce the additives,
breakdown the oil and drastically accelerate wear.
A true synthetic (Mobil 1 and many others) does not breakdown like pure
petroleum products. But, it can get just as dirty.
In a perfect world, using a premium lower-micron rated filter and changing
it frequently can allow a synthetic oil to be used over and over for many
miles and still maintain minimal total wear. The cost of using synthetic
oil is the oil, not the filter. Premium filters generally cost around $10.
Clean oil = low wear.

I have had the opportunity to study quite a lot of closely held
oil/filter/wear information. Here's the basics:
Keeping oil clean is the primary goal. What is 'clean'? The primary
component of 'clean' is particulate loading and particulate size. Your
normal paper oil filter filters out most of the particulates 25 microns and
larger. That's 0.001 inches. The smaller chunks keep circulating. Think
about a low viscosity slurry of oil and rubbing compound.
As the total particulate loading is reduced and the maximum size is reduced
by more efficient filtration, the total amount of component wear starts
dropping rapidly. Cutting the load and maximum size of particulates in half
results cutting the total wear by a square root function. There is also the
distinct probability that any single element pleated paper filter will be
leaking unfiltered oil (blow-through) by 3K-5K miles.
The other thing that happens is that the additives and stabilizers in the
oil are depleted and there is an associated breakdown of the polymer
molecules. However, I am aware of an experiment that ran petroleum oil with
double efficiency filtration that ran 30K miles while maintaining the oil
within all oil testing specifications.
Another factor is the contamination of oil with other liquids - fuel or
coolant - that serves to reduce viscosity and upset/reduce the additives,
breakdown the oil and drastically accelerate wear.
A true synthetic (Mobil 1 and many others) does not breakdown like pure
petroleum products. But, it can get just as dirty.
In a perfect world, using a premium lower-micron rated filter and changing
it frequently can allow a synthetic oil to be used over and over for many
miles and still maintain minimal total wear. The cost of using synthetic
oil is the oil, not the filter. Premium filters generally cost around $10.
Clean oil = low wear.
