Thats a great question. I keep asking myself the same question because I have some st3600 for my ranger in my shed. I keep telling myself that it would not be a good decision to use them with mobil 1 at a 6 month 6000mile OCI. What does everyone think. It is ok? I want the best for my truck but I think the supertech filters are a great filter. I don't know how they would stand up to the test of synthetics at this interval.
My thoughts on the subject are as follows:
Most folks here on BITOG feel ST filters are well constructed and generally do a fine job. Some feel the ST filter may be the best value filter available.
The problem is that the folks are using UOA reports (without particle counts) to determine the effectivness of an oil filter. From what I read a UOA without particle count will tell you next to nothing about the effectivness of an oil filter. So all oil filters seem to do just fine according to an typical UOA.
As an extreme Bob (as in BITOG) ran several thousand miles with no oil filter and his UOA indicated excellent results. Some of us came to the conclusion that the oil filter really doesn't do anything and is possibly unnecessary.
Based on testing (media examination, media flow rate, etc) the ST seems to be a decent filter. Not the best filter in the world but a decent filter. I have seen no data on ST filter real world performance (UOAs with paticle count).
My conclusion is that the ST filter is constructed reasonably well, filters near the middle of the pack, and would probably do an adequate job for 6,000 miles with most any motor oil.
There are lots of people running with sT filters and reporting few if any problems (but how would they know?). My Granddaughter has run 130,000 miles on Wal*Mart 5w30 dino and ST filters changed every 4,000 to 5,000 miles. Oil comes out reasonably clear, little usage, no complaints.
