Just cut open the oil filters from my first two services, each one has about 5400 miles on it.
The first is the OEM Honda, which is made by Fram. It has a floppy paper element which deteriorated and some fins folded over on themselves. More importantly, some small pieces were missing. The end caps are made of glued felt and retained by a narrow metal flange which only covers the inner edge of the felt.
On a positive note; the center core is metal, and the bypass valve is well constructed with a metal coil spring. The anti-drainback valve is good quality silicon rubber (although that doesn't matter with the filter facing up on the engine bottom).
New Honda filters use a modified nitrile rubber gasket that is fitted under a flange to prevent idiots from leaving the gasket on the filter housing and setting fire to their products. This occured with older

The problem occurs when mechanics remove the original oil filter at the first oil change. The filter's rubber gasket tends to remain stuck in the engine block, which prevents the new filter from sealing properly. Oil then leaks out onto a hot manifold, potentially starting a fire. Honda still insists the problem lies mostly with the dealers and says it would not be liable for any damages resulting from the oil filter problem. "The liability remains with the dealer," a spokesman said.

I bought a new Honda cr v, after the first oil change there was a engine fire. It was caused by a double gasket on the filter. The oil came out and went on the catolytic converter. A fireball under the car went into the engine compartment and caused damage. My wife is very scared to drive her car now. It could happen again. Next time it could be fatal.
The Mobil 1 has a rigid fiber-matrix element with full coverage metal end caps welded to a metal center core as a single unit. It looked as good as new. The metal coil spring bypass valve is slightly larger and well made. (Spring pressures are about the same.) The anti-drainback valve is also silicon rubber.
Mobil 1 uses a nitrile rubber gasket crimped into the base.
Both filter cannisters are heavy steel about the same gauge and roll pressed into the base.
The bottom line comes down to the element. I would never consider going two oil changes on the Honda filter as the manual states. It is just adequate for one.
The Mobil 1 filter element is clearly superior, and the M1-110 is about $11 at AutoZone, about $2 more than a dealership filter.
