I just bought a 1993 Subaru Legacy in excellent condition with
113,000 miles on it. I put Pennzoil 100% synthetic in the engine as
soon as I determined it wasn't an oil burner or leaker. I chose
Pennzoil because it was a little less expensive than Mobil 1 and should
be just as easy to find. Because I use a submicronic bypass oil filter
I won't need to drain the oil unless something happens like a leaky
head gasket. I feel that the synthetic will pay for itself by giving me
better fuel economy. Experience has taught me that a good quality
petroleum oil will make an engine last until the rest of the car is
getting pretty ragged if you have one of the bypass filters designed to
clean oil.
There is no way that synthetic oil is economical with the
conventional system of using filters that don't clean oil then draining
the oil at 7,500 miles. Using one of the bypass filters that use refill
elements that cost more than an oil drain would not be economical. To
maintain an engine in near new condition requires frequent filter
changes no matter what oil you use. The Subaru will need the bypass
filter element changed and a new qt of oil added about every 4,000
miles at a cost of about $5.00. I will change the full flow filter
every 2 years.
My old Subaru required four oil changes in 230,000 because I was
changing the bypass filter every 12,000 miles and adding a new qt of
Mobil 1. Although the old engine is in good condition except for leaky
gaskets it would have been in better condition if I had changed the
bypass filter every 4,000 miles. I probably wouldn't have gained much
because 230,000 miles was enough for me.
My 1984 Ford one ton diesel uses conventional Shell Rotella 30 wt.
and uses a qt of oil every 600 miles. Synthetic would not be economical
for it. I won't live long enough to wear it out using it for RV use.
Because it generates a lot of soot pulling a load, I installed a 500 HP
diesel rated bypass oil filter that will need 3 gallons of Rotella and
a $4.00 filter element change about every 10,000 miles or every couple
of years. If the oil analysis looks good I will extend that. Right now
I am just estimating.

Throw a fuel line magnet on your suby and don't forget triple toilet
paper filters. I hear that's what got Lindbergh across the Atlantic.

You're sending him out without tin foil in his hubcaps?
You beast!

Damn, Tscot, you let the secret out of the bag. It really was those "fuel
line magnets" that pulled Lindy accross the ocean. The magnets actually
pulled the plane towards the Effiel tower, which of course, is made of iron.
The engine in the plane, was actully just for show. It was decoy, to hide
Ralphs secret magnetic propulsion system, from the evil Albanian spies. Even
though the engine was just a decoy, it did run one of Ralph's "triple toilet
paper, super bypas, stop everything, increase everything else" filters.
Ralph has actually improved on his original design. He 's about to release a
new and improved version, that runs on used toilet paper!! He'll be
releasing details here, in the this newsgroup, next month. Stay tuned.

I thought he was flying away from the Eiffel Tower. Wow! That's some

No, Lindberg flew from the U.S. to Paris, but thats not really important. If
he wanted to go the other way, he would have simply reversed the polarity on
his "fuel line magnets". <VBG>
