Why a Peterbilt Locking Fuel Cap is Necessary
As a Peterbilt truck owner, I’ve learned the hard way that a locking fuel cap is essential. Here are a few reasons why:
- Prevents theft. A locking fuel cap is the best way to deter thieves from siphoning your fuel. While a thief could still break into your truck and steal the fuel, a locking fuel cap will make it much more difficult.
- Protects your fuel from contamination. If you’re ever forced to refuel at a sketchy gas station, a locking fuel cap can help protect your fuel from contamination. This is especially important if you’re using a diesel engine, as diesel fuel is more susceptible to contamination than gasoline.
- Keeps your fuel from evaporating. A locking fuel cap can help keep your fuel from evaporating, which can save you money in the long run. When fuel evaporates, it takes some of the energy with it, which means you’ll need to use more fuel to get the same amount of work done.
A locking fuel cap is a small investment that can save you a lot of time, money, and hassle. If you’re a Peterbilt truck owner, I highly recommend getting one.
Here are a few specific models of Peterbilt locking fuel caps that I recommend:
