Hi Everyone, Have been switching back and forth a few times over the past 10k miles and it seems the Becker has a slightly higher oil pressure whereas the UFI is slightly less. Anyone else notice this???
Steve -- you've (understandably ) got a case of "audio on the brain" -- it's "Baldwin" (but I've no data regarding output pressure for Baldwin vs. UFI)
Yes Baldwin. Darn June end of month means i have not one but TWO audio magazines i am working on getting out by the 30th. So yeah, the BALDWIN versus the UFI (new version). Steve M., i swear there IS a difference between the pressure readings and why i waited for two UFI and three Baldwin changes to BE SURE i was not imagining things.
I certainly don't dis-believe you -- I just don't have any information on the subject myself. Since the oil pressure sensor is on the output side of the oil filter one has to conclude that the pressure loss thru the Baldwin filter element is less.
I wouldn't trust my oil pressure gauge to be, as Vinny's girlfriend would say "dead-on balls accurate" or calibrated by the Department of Standards. Mine acted funny and then crapped out - I figure +/- 10 psi variation, easy, potentially on the same vehicle over time. I have way more oil pressure than I used to, according to my new gauge.
Ahh ok. Am also right now studying the oil. i SHOULD HAVE purchased one of those testing kits and sent some off. Now i have a few gallons of oil in the holder awaiting to go to the recycle center. The old oil looks good, if a bit thinner and not quite a pure/clear than the new oil of course. Smells ok, but i have a feeling the way i drive i may want to consider changing the oil every 2k instead of every 3k. Next oil change will use a Baldwin, then a UFI after that. Would be interesting to have the oil analyzed after each different filter to see what the results would yield. Hmmm...
As the oil gets hot, and over time/use, it thins out a bit and therefore the pressure is lower. read: thinner oil means lower pressure.
NICE setup and have been debating going that way myself. There is plenty of room for such things in the Euro 308 so please tell me, how do you like it? As i said earlier, it is a SLIGHT drop overall, but still well within specifications. It is simply me keeping an eye on all gauges (when safe) during drives.
Steve, Were you taking the readings at the same temp and same rpm reading? Was the oil subjected to a lot of winter stop and go, short drives, (possibly diluted a bit more with fuel/ condentate?? And also important, was there any switching of oil brand or viscosity? Maybe PM Ali Hass, our esteemed oil guru. Or Maybe ask Vinnie's girlfriend. Best chris
Chris, Same oil, same temps, same rpm, etc. Fully agree there MUST be "control" and as a professional photojournalist i am VERY aware of keeping things on equal ground for comparison. Still, VERY good call and fully agree everything MUST be the same other than the filter. This is ALSO why i waited a few changes, over a year's worth of testing, and switching back and forth of the filters during a fresh change to be sure of my findings (not just the odd one-off "bad" filter or the like). FYI: Also notice that the oil pressure comes up faster from "cold" with the UFI versus the Baldwin. The UFI is about 1 second versus about 2.5 for the Baldwin. Naturally this ALSO depends on just how "cold" the oil is. Keep in mind i have started the car from "dead cold" at a room temp of 75F... to -10F(!).
Factory gauges of all types are notoriously inaccurate. I ran an oil pressure test with a mechanical gauge starting cold and checking at various RPM's as it warmed ending with the final test at 6,000, full hot per the WSM. That way I have a baseline to compare to in the future if and when a pressure anomoly pops up. Because I have to run my 308 pretty hard to keep up with the 355's, 360's, my buddy's TR and the occasional F40 I change my oil every 2,000 miles. I use VR1 Racing (dino based).
Thanks. The truth is I only did it because the stock one was in the wat of the blower. I bought the twin filter adapter because it was about the same price as a single, couldn't hurt (which means it looked cool) and fit nicely in the space I had.
