so you take longer to charge the total 16 (assuming the aux tank is also 8 gallons for easier calculations) gallons?
assume it takes 1 min to fill up 8 gallons.
now it takes an extra 1 minute to fill the aux tank.
so at the beginning, it takes a total of 2 minutes, when you first start working.
but this allows you to work and remove all 24 lugnuts off your toyota truck before the compressor kicks in again.
now, assume you only have the 8 gallons and no aux tank.
initially, it will charge the tank for about a minute.
but now, you can only remove 12 lug nuts (or half as much) before the compressor kicks in again for a full minute.
so in total, the compressor still operates for a total of around 2 minutes in both cases.
in the end, it comes down on the quality and the design of the motor on whether it works better when working in shorter periods vs longer periods but longer "rest" time.
but when it comes down to it, it probably doesnt matter...
now we havent even talked about how much the extended warranty, worked at the 3 year period...
if it were up to me, slap in the aux tank and dont worry about it. it's a HF product...
