I'm guessing he means "2 to 3 gallons in one hour". 23 gallons in one hour is called a running tap - no household RO/DI unit will do that volume.

And in respect of the OP, many modern cars can actually run for years without a single oil change. But take apart the engine of such a car and you'll see some significant damage. The same goes for your pre-filters. It's called "maintenance" for a reason - you need to do it to maintain your RO/DI unit. Don't be lazy or cheap.
