One advantage to the taler filter is that it actually decreases the pressure through the bypass adapter and therefore allows more oil to be filtered instead of bypassed.

Im running a stock pan. I have a 1.5 quart oil accumulator and about 2 qts fit in the lines and cooler. plus the deep filter, takes about 9 qts.

1218 is the same size as pf35l

whats the difference except for the fact the 35l costs 3 times as much

For me to show full on the dipstick when I change my oil, I need to add a little bit over 5 quarts, probably 5.2 quarts I would say. I've put in as much as 5.5 though. Considering the fact that a little bit of oil will always remain in your engine when you change your oil (some is stuck in the oil pump and surrounding area, some in the heads, etc.) I would say the TOTAL oil capacity is probably almost 6 quarts.

Running the bigger filter only adds about an extra 1/4 of a quart capacity, but every little bit counts.

The PF35L filter is totally different than the PF1218 though, the PF35L uses a synthetic media and filters down to 12 microns, while the PF1218 uses a cellulose media (mostly paper) and filters down to about 25 microns.

I still prefer a high flow filter over a super low micron filter though. With the large clearances in the LT1, you don't need a filter that takes out super small stuff, as anything below 20 microns or so will pass through your engine without causing much if any wear.

I used a long style filter on my car, once. I hit a big bump one time and scratched the hell out of the bottom of the filter. I am lucky it never tore the filter off or put a hole in it.

I have an oil cooler still, so that's probably why it hung down too low.

You want "big".... I gotcha BIG right here.....

Moroso 2 Qt. / 8" filter

yea i cant see using one with an oil cooler! my y-pipe hangs the lowest on my car! well the subframes do too..

Dave Feerst

I dunno what you guys are talking about, I use the 1 qt filter with a cooler thats about 1/2 thicker than the stock one and it sits about level with the bottom of the k member. Mabye if my car was lowerd it would be a concern.

Dave Feerst

Anyone ever try one of those clamp on oil coolers? just curious if anyone tested them. They wrap complately around the filter and are basicly a big alumnium heat sink....synk....sync.... whatever...

DAYUM now thats a FILTER only filter ive seen like that was on a semi truck!

theres some dayum good info on that page too! talks about the same stuff that Patman was talking about..

Injuneer

Yes, those filters look good on paper. I bought a couple of the 1 Qt. size. I was using the UPF 1218 synthetic media filter, after they discontinued the PF35L. But the logic of limiting the filtration to something larger than 10 microns seems to make sense, so I'll try the Moroso filter.

I use the long WIX version. Its slightly lower than my Hooker LTs but not lower than the flange.

I use to put 1/2 quart extra for my 383.

I'm upto one extra quart now with the longer filter.

Patman

Where do you get them, and how much $$? I love the idea of being able to run even more oil in the system!

Jegs and Summit carry them.
