Oil Filters for the LS1
 

Anyone here use Baldwin Oil Filters? ...they are supposed to be top notch, well made, and excellent. Size for the LS1 is a B31.

Howdy, Peter!

I've been using the Baldwin B31 for a year or two. I noticed a small increase in oil pressure (on the gauge) across the board when I switched from the UPF to the Baldwin. The Baldwin appears to be a little less restrictive.

I have my oil analyzed yearly. Haven't noticed anything really different. All in all, I am quite satisfied with the Baldwin.

I use a K&N. . .

I like the NAPA Gold oil filters. They are made by WIX and are top notch... :thumbs:

:iagree:
AND the price is right, too.

I'll third that for the NAPA gold, however O'Reillys auto parts carry the WIX filters for a buck less than NAPA

The K&N and Baldwin are both excellent filters. Both exhibit low pressure drop despite very good filtering qualities.

I use the mobile one filter.

I'm very happy with the results I've gotten with the K&N oil filter. This filter combined with German Castrol 0w30 has given me the lowest engine wear of any LS1 (according to oil analysis results I've gotten compared to any others I've seen posted on the net anywhere, nobody else has come close to my numbers)

As an example, here is a sample of my engine wear numbers on my last interval, which was 8000 miles:

Iron-9
Lead-4
Aluminum-3
Copper-3
Chromium-0
Nickel-0
Tin-0
Silver-0

I know that the high flow ability of the K&N oil filter is partially responsible for my low wear numbers. In hard driven applications, high flow is more critical than super fine filtering ability.

I use Purolator PremiumPlus filters. Highest flow rating with best filtration combined. Read tests here:
www.oilfilterstudy.com

Take a look at the link to the Grease oil filter study spreadsheet to see media flow rates and filtration efficiency.

The filters in this test are the old style SB Chevy filters used on Mercruiser stern drive engines (Basically all Chevy SB engines. I have a 260HP 5.0 MPI in my 24 ft. express cruiser), but the flow and filtrations rates are similar all filters since the same materials are used, so the comparison is valid.

I also use a tall filter even though it sticks out a couple of inches below the oil pan.

Did a little research and for filtering and flow the Baldwin seemed one of the best. Construction also considered good.

Mobil 1 extended life or K&N used here

I run Baldwin B31 OF for about 2 years and I had no problems. I've been told they're less restrictive... hoping they're correct; only have 11,000 miles :rolleyes:

I use Baldwin B31s exclusively. Buy 'em by the case here. :thumbs:

The OEM filters are fine, but they were designed for the lowest common denominator -- the type of person who never changes the oil unless the car happens to be in for some other service. IOW... excellent, long-lasting filtration properties, but not so good flow characteristics. For the typical enthusiast (i.e., the type of person who hangs out here), there are better-flowing choices, primarily the K&N and Baldwin as mentioned by Dave68.

The oil study results (see link provided by Alex D) figured heavily in my decision. Even with benefit of this study though, it still comes down to personal recommendation and preference IMO. Reason being, that the oil study does not define terms such as "average," above average" or "good." Without knowledge of the "average" result (is it good, great, or lousy?), it's difficult to know with certainty which ones are quantitatively superior.

I've been using both air and oil filters from Baldwin for over a year now.
Seem to do a good job.

Thanks for the link :thumbs:

Anyone know what size wrench cap will fit on the B31 to take it off?

First, thanks a million for the link and advice - the Purolater sounds great - but do they have it in the standard C5 length? I personally know of one C5 that bottomed on the filter, tore it open and suffered engine damage (and tow truck damage :eek: ).

NVG. :(

Be careful with that long filter.

I just began using mobile 1 filters in my ride and I am happy with them.

:iagree: :thumbs: :cheers:

Napa or amsoil filters to go with 10-30 amsoil
