Pressure vs. Splash Lube?

I'm looking at getting a generator to replace my Lp3250. I see there are generators with engines that have pressure lube and splash lube, with most of the ones being splash lube. What I am wondering is if it's worth it to get one with pressure lube or if splash lube is fine. I really like the idea of having an oil filter and all. The generator will usually be run at least once a week, and sometimes daily. Another thing that sometimes happens is it may get run for 2-3 days straight especially over the summer on camping trips. I plan on getting one with a reputable engine such as Honda, B&S, Kohler, Generac, etc.

If the unit is used on somewhat level ground, it really is a minor consideration. Engine quality is much more relevant than pressure/splash lube.

A honda GX series is probably the pinnacle engine for a small general purpose generator.

Splash lubrication requires ether low friction (ball or roller) bearings or larger clearances for plain bearings. Obviously splash lubrication precludes an oil filter and also a low oil pressure shutdown device. You CAN have a low oil level shutdown device. Oil level is a bit more critical with splash lubrication, too low and and the dippers may not "lift" enough oil and too high the oil may get mixed with air to a froth. Other than these items there is nothing wrong with splash lubrication.

On the plus side, splash lubrication eliminates a power-stealing (small amount of power) oil pump and another piece of machinery that can fail. Personally, I would not be too concerned about the lubrication method but instead look for overall quality of the engine and generator.

Well, I got my new one, a slightly used Generac 7550 EXL with only 20 hours for only $500.

Well, it's definitely not an inverter or diesel generator. If you think this is loud, though, you should hear the Chinese ones that people were using for their parade floats last Halloween. My PA system is still louder, though.
