Oil Filter kit from Flat 6

[litteng]

I also asked this question at pelican parts on the boxster/cayman forum and received i very nice summation... won't link it you can find it easy enough.

theres been a lot of discussion about oil....

everyone has an opinion...

i'm no expert so don't ask, i won't tell; and we can still all remain friends

I'd like to add my opinion; I'm an Amsoil fan, http://www.amsoil.com/ , I like the research they do to stand behind there products. They don't just sell oil products but the whole lubrication family is involved. To take their love of engine protection to the next level they also provide a remote oil filter and a by-pass filter system. The by-pass filter will filter 100% of your oil every 5 minutes down to 1 micro!

The product line goes one better for those looking for the best in preventing wear...a 160cc preoiler that provides oil pressure prior to starting the engine.

The post I made on Pelican pretty much sums it up, but I'll also add that using a metal filter body lets you use filter magnets that I've tested as removing all but 1 ppm of Fe in used oil. Secondly, using one of the recommended filters that don't have an internal bypass are full-flow, filtering 100% of oil, not allowing ANY particulate matter to be bypassed, with filters capable of higher flow while still filtering much finer particles. These filters are built to take pressures far exceeding anything these engines can produce, even in sub-freezing weather as we have tested.

Amsoil is good too (just don't use their european formula - it's pretty weak), so are their filters - just cross with one of the filters we recommend and you'll be fine using Amsoil's. Royal Purple also now offers some nice filters too!

As far as oils go, I'm leaning towards Swepco 306 15w40 for non-variocam+ engines. If using a factory approved oil or lighter recommended 0w40 or 5w40 viscosities, I'm also thinking about recommending Swepco's 502 Oil Improver. This boils down to the bearing analysis we had done on the IMS and their failure modes - having an oil with moly-based extreme pressure friction modifiers should improve IMS life. Royal Purple's 5w40 would be another oil as laden with moly as Swepco.

For sure, drain intervals need to be cut back to 5,000 mi / 6 months.

how about castrol tws10w60 or castrol Edge 10w60 (not edge sport !!!)
It has extreme hths values and that's the reason why it is the only oil approved in bmw ///M engines.

I put it into my m3 and Mits. evo, an former impreza, all the time. Would love to have a single type oil supply and put into the Boxster as well. However did not dare to do that until now. BoxsterS runs on M1 5w50.

Now reading about extreme pressure modifiers (zincsulfait ???) being neccessary for the box. There are a lot of that in tws/edge 10w60. In fact the only reason tws/edge 10w60 exists next to Edge sport 10w60 is that bmw ///m didnot approve the lower zincsulfait and lowe hths values in edge sport 10w60...

The Porsche oil filter allows you to see what it has caught without having to saw off a metal cannister.

Paul,

I feel the same way, I change my own oil and ever since owning my Boxster I love having the ability to inspect the pleats for contamination. If people want to strap magnets to the outside of the housing I suggest using magnets from old computer hard drives. They're so powerful you can put a set on each side of your hand and they'll stay there.
