Executive Towncar powered with PropaneDid you know that Rainier Limousine now has added propane-powered Lincoln Towncars to its fleet? That’s right, we can get you where you’re going with one of the cleanest burning cars on the road.

We have been driving our propane-powered Towncar for a few months now, and have noticed that there is virtually no difference in how the car performs, and we really like the fact that we’re burning a cleaner fuel.

This brings up an interesting question…do you know what the difference between Propane and Liquified Natural Gas (LNG) is?  As you can imagine, there is a lot of science behind the differences, but for brevity sake, we’ll just give you a couple of the main differences:

  1. More Refined – Propane is an actual ingredient in the natural gas that comes from the ground.  Natural Gas is mostly methane, with butane, ethane, and propane as components.  The Propane gas is refined out of the natural gas, which makes it more potent.
  2. Higher BTU’s – Because Propane is more refined than LNG, it is in fact more potent, which means it has a higher BTU rating than LNG.
    1. Propane = 91,410 Btu/gal
    2. Liquified Natural Gas = 84,820 Btu/gal

This also applies to your barbeque grill or kitchen ranges.  You can get the same BTU ratings on these appliances, but you’ll use more LNG doing so.  Anyway, just a little trivia for you. 🙂
