i use K&N filter (the small one) and run Royal Purple....is it overkill....probably

i prefer the delco filters over fram....but have used both with no problems

i change my oil in the bonne every 4000 KM thats what was recomended to me by my mechanic who owned 3 SSEi he saw too many bottom end bearings go

like i said thats what makes me feel comfortable
my winter beater has a fram filter right now and castrol oil .
i change it every 5000 to 6000 km

hope this helps

I can make an oil volume kit and sell it to radomirthegreat for lots of $$$$. It will consist of a deep sump oil pan, 3 filters, and an oil cooler. It might raise the oil volume capacity to 7 quarts... sale price, 1.75 arms and 2/3 of a leg.

y'know, since i've gotten rid of the bonne, i haven't thought about oil pressure much.

i don't have but 4 gauges.. fuel, engine temp, tach, and speedometer. time for the ss cluster so i can monitor oil pressure.

does aeroforce monitor oil pres.?

Just an update for me...

changed the oil in the truck yesterday over to Pennzoil Platinum and a PureONE filter.

Also, little error on my part, I thought that a PF52 equiv would fit where a PF46 is called for, being that 3800s call for a PF47, oh boy was I wrong. Same filter, longer, but the THREADS are different. The screw on/oil exit part has a much larger hole and finer threads on the PF46 equiv filter....had to take a $30 cab trip back to advance to exchange.

Considered between a Mobil1, PureONE and K&N filter. Being that Mobil1 and the PureONE have the smallest micron filtration ability, with the K&N being higher flow, unknown micron filtration, I got the PureONE for $6, over the M1 for $10, and the K&N for $13.

Removed a Delco PF46 as the old filter.

Reported change, somewhat of a pressure drop from dino (dealer) and a delco filter. Pressure @ 3000 RPMs
Old: 68-72 PSI
New: 55-58 PSI

Pressure @ Idle/ ~700 RPMs
Old: 42-44 PSI
New: 36-40 PSI

PureONE definitely filters more, but as mentioned from quite a few sources, cuts flow.

Next will be either a K&N or M1, depending on new information at the time with Mobil1 oil.

New OCI, 5,000 miles

I was just going by the title, but I'm aware of what they do.

If I have about 1000 miles on my oil, should I even need to send it to Blackstone? I think there'* something weird with the engine, and I might end up tearing it apart soon. I'm also looking into swapping in a Series 2 L67 with my 4T60-E HD because the transmission only has about 40K miles on it.

wjcollier07, what you said about Purolators is exactly what I thought. I'm absolutely going to put a Mobil 1 oil filter with synthetic oil in the SLE to see if that lets the oil pressure rise as drastically. It has almost 5000 on its oil.

Then, I'll cut up the Purolator and actually show you pictures! Isn't that awesome? Really, I will upload some pictures that I'll take with the camera so that we can look at a 5000-mile filter from an easily driven car.

As for the 94, I'm very, very close to figuring out what'* up with the electrical system, and then I'll get back to its oil issue. It has not been started since perhaps the end of November, and I've replaced already all the battery cables. The battery connectors look awesome! More on this perhaps tomorrow.

I take that back in its entirety.

Purolator PureONE filters DO NOT inhibit flow. Oil pressure is back up PAST where it was before the change. Looks like you need to let the oil break in the filter for about 50 miles, and then pressure returns.

Pressure now, after about 80 miles on the new oil

Hot Idle (700 rpm) - 41 to 45 PSI
2000 RPMs - 60-65 PSI
3500-4000 RPMs - 72-76 PSI

EXCELLENT pressure.

I should also mention that I ran a nice mix of seafoam in the old oil for the last 150 miles of driving. About 7/10ths of the can for 6 quarts of oil. Pressure went pretty low for the majority of this 150 miles of driving (all in one trip) sub 35 psi @ hot idle, worried me a bit, but as mentioned, pressure now better than ever. The seafoam also turned the somewhat new dino, which was PRETTY CLEAN, only having 2k on it in a 32k engine, BLACK. There must have been quite a bit of nasty crap built up already, no idea how, being that the oil in this truck has always been changed every 3k/3 months.

ANOTHER bit of good news. Average fuel mileage has gone from 15.6 to 16.3 (DIC), same route of driving, maybe MORE city driving.

All I can say is Amen to Seafoam, Purolator and Pennzoil Platinum. (and of course, my favorite M1)

I have a great addition to this! There'* a Sable we own that was completely trashed. We tried to fix it up as much as possible, but there'* a lot of carbon buildup. I'll see how some oil filters do. Good news for progress but horrible news otherwise is that we're using a Fram on it right now. It'* also good that the cases are most probably easier to cut.

In the recent past Ive used Purolator Premium Plus.
Currently running Quaker State filters I got from BOGO sale at Menards(made by Purolator)
I also have 4 Pepboys Proline(also Purolator) Got them BOGO too!!

All these are great filters, work just fine in my Bonnie and Dad'* Park Ave.

I change oil/filter at 3000-4000 miles depending on weather/free time with whatever dino is on sale(Currently QS in the Bonnie, Chevron Supreme in the Buick)

I have a mini stash of Pennzoil/QS going in next...

I just did an oil change this past weekend. 5 Qts. of Royal Purple +5 Qts. of valvoline and a K&N gold filter. The guy behind the counter gives me a funny look and asks if I need a second filter, I reply ... No thank you. He said what about the filter for the second car? I told him I was only changing the oil on one car and the guys asks if I plan on putting in all 10 Qts. I told him no, I use the valvoline to flush out the sludge and dirty oil before I put in Royal Purple. he gives me a look like I have gone off my rocker.
What can I say, I use clean oil to flush my engine and when it comes out looking the way it went in then I know its as clean as its going to get. it only takes about 3 Qts. to flush out any leftover gunk.

That is an interesting oil change ritual. But if you're going that far, why not just take off the oil pan and clean it up? But really, that'* good. What'* your oil pressure with the K&N?

I did an oil change on my SLE. Contrary to what I had said about the Mobil 1, I put on an AC Delco. I thought back to this thread, and I remembered that it'* all Champion Labs anyway. I'm sure the Mobil 1 can probably take more oil pressure, and it should have better filtering media, but the AC Delco is cheaper. Economy over promise.

Here'* a video I shot on the highway of my SLE racing a ricer whose passenger was mooning us while screaming racially insensitive remarks.
http://www.youtube.com/watch?v=6Z9LByaCZLo
You can see in it how the car'* oil pressure now is with ~5 quarts and an AC Delco PF52. About the first half of the video shows a 60mph roll. From just past halfway through, there'* generally good acceleration into 70mph. I believe this shows the pressure as being 50psi at a coast and a tad higher otherwise. What do you think?
