Jim,
Thanks for the oil change suggestion. I think you're correct except that I
added the CD-2 detergent additive. Most have suggested that I change the
oil soon so no "crud" is loosened that might block a line or opening.
There was a Wix filter on the car when I bought it. I just took the Wix
filter to a parts store for them to look at a conversion chart. They gave
me the Fram PH2825. Are Wix filters better than Fram? I have a Napa store
also nearby, so I could probably get a Wix filter.

Steve,
I think originally they called for 20W-50. Certainly nowadays you won't be
driving around in winter (I'm guessing) so you don't need to worry about
it
being too thick in the cold.
I'd just wait a while to get a bit of use out of the oil that's in there
and switch at the next normal oil change interval, or maybe when it gets
hot again next summer.

PS I am about to switch to a spin-on adapter - how did you determine the
Fram PH 2825 number? Ultimately I want to find a Wix that will fit but I
guess there'll be a cross reference. (UAP/NAPA filters are Wix inside by
the way, at least around here).

Subject: TR3 Oil Presure Question
I have had my TR3 for almost a year. I haven't driven it much because the
car spent probably 8 of the last 12 months in storage. This weekend I
changed the oil for the first time. The previous owner told me he changed
the oil every 6 months. Well, the oil looked like it was crude oil - black
and thick.
Anyway, I added Castrol 10W-30 and replaced the the existing spin-on oil
filter with a Fram PH2825. For good measure (I think and I hope), I added
CD-2, an oil detergent, with the thought that I will change the oil again
in
a month before I put my car away for seasonal storage.
Now my question: Before changing the oil, oil pressure was consistent at
50lbs (at idle and at speed). After changing the oil, the pressure was at
60lbs, then quickly stabilized at 50lbs. Good. I took the car for a spin
to get the engine very hot and to check for leaks. After a bit, the oil
pressure, at idle, dropped to about 30lbs. At speed, the pressure was
about
50lbs. By the time I got home, oil pressure, at idle, varied between 20lbs
and 30lbs. There are no leaks (other than normal) that I can see. The
engine and operating performance ran like a charm; very strong.
I looked at my TR manuals that said that oil pressure should vary between
30lbs and 70lbs. Should I be worried that oil pressure drops to 20 lbs at
hot idle? Should I worry that hot at idle oil pressure droped to 30lbs
from
50lbs previously? Or is this simple a result of clean oil? Should I be
using a heavier weight of motor oil?
