Who was it in the Subaru group that mentioned my low oil pressure might be caused by my using Fram oil filters?
There may be something to this.
I picked up yet another 1992 Grand Something-or-other (in this case, a Grand Caravan. The last two were V'gers...). It has 239,000 miles on it. I got it on eBay for $150 and had to go 135 miles to pick it up. To make a long story short, we had to cut and crimp one of the rear brake lines to get the thing to move without emptying the brake cylinder, and the plan was to drive it within 100 miles from home and call AAA..."It blew a brake line!"
No need. The crimp held and the thing ran so well I drove it the entire way home! Of course, I told "Jane" to avoid highways, so it was 92 miles through Providence and back into Mass and on to home.
All the way the oil press. guage was about 1/2 way up the guage, occasionally dropping a little below on a 68 degree November day in the middle of Providence. Other than that, it stayed right around the halfway mark the entire trip.
Today I gave it a 'service', oil change, air filter and tranny juice and filter. I used a Fram TG oil filter since if you bought a jug (5 qts) of Valvoline oil you got the filter $2 off. Maybe it's just on the Subaru?
NOPE! After I changed the oil and took it for a test, the oil pressure guage had dropped a whole mark off halfway! I don't believe it!
I'm going to wait until the next nice day, pull the oil filter and put on something like a Wix. Never had that problem with either OEM or Wix filters, and Wix got high ratings from Consumer's Reports.
