Dennis, that is a great site! I read it for a couple of hours last night--what a bunch of obsessive oil geeks...

Lots of good knowledge on oil, but high dork factor. Place propeller cap on tightly before entering.

The numbers in my post and "BITOG" in Unabomber's post are in blue. Put your cursor there and click on them when it turns into a pointy hand.

Yeah, I've got 3 or 4 from my '98 Legacy 2.5GT. Do you want me to type them all out, or want something specific? Or just wait until you get a result back to compare?

Default Okay, here it is. Pasted from a Word document I created (available via e-mail)

Vehicle- 1998 Subaru Legacy 2.5GT
Engine- Phase I, 2.5 liter DOHC

Driving Habits- Fairly routine driving habits. I enjoy driving the car quickly, but do not rap it out through the gears each and every time. I do autocross the car approximately 12 times per year (lots of trips to redline in 1st and 2nd gear). Commute to work is 17 miles, 14 of which is highway, driven at 70-80mph. Avg. fuel economy is in the 21-23mpg range with my driving habits. Obviously higher on road trips.

Location- Oklahoma. The summers are long and hot, with temps in the 85-105F range for most of the summer (mid-May through late September). Winters are generally mild, with temps in the 25-40F range, but we can get down into single digits at times.

Purchased car used in Portland, Oregon in May of 2000, with 17,500 miles on it. Drove it home to Tulsa. Promptly changed all fluids to Amsoil synthetics. Gearbox, rear diff, and engine. Also installed Amsoil oil filter, and Amsoil two-stage air filter (which has recently been replaced by standard paper- got tired of cleaning it).

First Sample;
Oil – Amsoil 0W-30
Filter- Amsoil SDF36
Miles on car- 27, 261
Miles on oil- 7,841
Time on oil- 5 months (May thru Oct.)

Second Sample;
Oil – Amsoil 10W-30
Filter- Amsoil SDF20
Miles on car- 38,339
Miles on oil- 8,276
Time on oil- 4 ˝ months (Dec thru April)


Third Sample;
Oil- Amsoil 5W-30
Filter- Amsoil SDF20
Miles on car- 55,132
Miles on oil- 10,034
Time on oil- 9 months (Sept. thru June)


Fourth Sample;
Oil- Amsoil 5W-30
Filter- Amsoil SDF20
Miles on car- 73,311
Miles on oil- 9,412
Time on oil- 12 months (Dec. thru Dec.)

The following had zero ppm for all samples, so I won’t list them other than to let you know they were Ti(titanium), V(vanadium), Cd(cadmium), Ni(nickel), Ag(silver), and Ba(barium).




Sample 1 notes;
Nitration elevated- check pollution control system
Oil is suitable for continued use
Change full flow filter, if not done when sampled
Top off system
Resample at next regular interval
Normal wear indicated


Sample 2 notes;
Normal wear indicated
Oil is suitable for continued use
Change full flow filter, if not done when sampled
Top off system
Resample at next regular interval


Sample 3 notes;
Viscosity is out of indicated grade
TBN low

Change full flow filter, if not done when sampled
Top off system
Resample at next regular interval
Normal wear indicated





Sample 4 notes;
No corrective action required
Oil is suitable for continued use
Resample at next regular interval

The Word document that I created is a little easier to read. I can't separate the columns on this post the way they are separated in the document. If anybody wants me to e-mail it to them, let me know. I'd be glad to send it.

Rich
(I know I'll get flamed for the intervals. )

Hey Rich, click the button with the "#" on it when you post columns. It'll give you monospaced text:

Code:
Item1    12    34
Item2    56    78
