Oiling issues

There is a reason Systems 1 put a sleeve inside their filter. To stop **** like that.

It’s hard to see in the picture but is there a screen or something inside to keep it from collapsing?

If it’s a race car and you have a 40 micron screen it will filter everything you need.

I know this. A screen filter is far less restrictive than other filters.

It’s great to filter flea shot out of the oil until the filter is so restrictive it causes the engine to not get enough oil.

You can test this with a gauge before and after the filter. I’ve seen 12-15 pounds more pressure with a 40 micron S1 filter.

That means 70 pounds was going into the filter and 55 was on the out to the engine.

That’s not very good.

40 micron filtered oil is far better than 20 micron filtering IF you are losing that much pressure across the filter.
