Forget propane, in 20 lbs tanks it's around $4 a gallon, $5.80 gasoline equivalent. (88,000 btu per gallon vs 128,000 btu, from memory could be off some).
When adding a extra fuel to the air stream the car's LTFT(Long Term Fuel Trim) will go negative using less gasoline, you'd really want that amount of fuel to be constant ratio with the air flow so that the LTFT doesn't jump all over the place. The most you can do without getting a CEL is about 20% of fuel demand. Open Loop or Closed loop the LTFT is still used to adjust the mixture.

I'm gonna say this as nicely as I can... WHERE TF DO YOU LIVE THAT PROPANE IS $4 A GALLON?!
It is 2.16-2.36 depending on the time of year here at my local Tractor Supply. I use it for my grill, and a full tank costs me like 15 bucks after tax.
Gasoline on the other hand, is at 2.66, but it's only been there for maybe 5 days, it was 2.87 for a long time, and 2.95 all summer.
As for everyone saying to add a second car, I'd really rather drop the 800 on a potentially useless propane system. I just added my gf to my insurance and it went from 157 dollars a month to 396 a month - drivers that use their car for work pay MUCH higher premiums. Adding yet another car, and a new one at that, would have me paying probably 700 a month for insurance, plus a 2-300 dollar a month car loan payment?!
The point here is to save money lolol.
