Bypass system
1. Type/brand of bypass filtration system?
2. Type/brand of oil used?
3. What lab do you use for oil analysis?
4. How about some pics?
To answer Chris first, The spin-on filter on my 5432 is horizontal on the starboard side of the engine and yes it is a bit of a mess. I minimize the mess by slipping a small (4x6x4) foil pan under the filter so that drips, etc fall into the pan. Then I'm carefull to keep the filter upright until I get it out of the engine compartment. With the engine off, there's no pressure on the oil system but the filters are full of oil.
The other filter is behind the engine on the bulkhead between the engine and the quarter berth and it's a mess to deal with too. It's vertical and the canister top comes off with a clamp then you lift out the element and stick a new one in. It holds about a quart of oil. I just use a bunch of oil-sorb pads under the thing and have a plastic bag ready to put the old filter into. Then there's usually a few drips that need to be mopped up. The tension on the clamp system is critical.
1.)The system I have is sold by Gulf Coast Filters, it's called O1-JR , the oil feed is tee'd off the oil pressure plug and the return (on mine) is tee'd into the oil pan drain hose. If I recall, I think it cost under $200 and I installed it myself.
2.) I've been using Shell Rotella Synthetic because it is compatible with about any oil I add ... I always try to add the Rotella Synthetic but it's not available in the islands ... however other Shell products are so I try to stay with Rotella or the islands version of Rotella.
3. The lab is Titan Labs affiliated with Gulf Coast Filters. I buy prepaid mailers from GCF (about $20)...the results come by mail. However, mailing a sample from the Bahamas takes about 2 months to get results back. GCF maintains a file on your engine so they can compare past results to the current test.
4.) I'll try to get some pictures.
GCF's website is

I have no affiliation with them ... I'm just a customer. There are other systems... Amsoil sells one if I recall. I chose the GCF system because it modifies things the least and leaves the Universal system intact. If I were to have a problem with the bypass system, I can just plug it off and my engine is then back to its stock oiling system.
