Diesel Fuel Nozzles Don’t Fit in Standard Fuel Cars

Diesel cars are not popular in North America. But, diesel engines are fairly popular in pickup trucks and are becoming more popular in North American cars.

Although they have a limited history in America, foreign car manufacturers sell many diesel models in Europe.

Diesel engines are generally very efficient and that behind their new found demand. As diesel becomes more popular, you will likely see more diesel pumps.

This is good if you have a diesel car, potentially bad if you don’t. Diesel pumps present a slight risk to your standard gasoline vehicle — you do not want to put diesel fuel in a car that uses standard unleaded fuel.

Standard engines use spark plugs to burn the fuel, diesel engines use pressure and heat to cause a reaction in diesel fuel. That means standard engines will not burn diesel fuel. If you inadvertently put diesel in an unleaded car, the engine will stop very quickly. It’s not usually a total loss, the fuel system will have to be cleaned, filters will need to be changed and the whole process can cost as much as $600.

But, there is an easy way to avoid this costly mistake. First, diesel fuel dispensers are usually clearly marked with text and with a special color handle (the color varies by station).

Second, the nozzle on the end of a diesel fuel pump is slightly larger than a standard fuel nozzle. That means it won’t fit in your car’s gas hole, at least not that way you’re used to a pump nozzle fitting. If you notice that the nozzle isn’t going as far in as it usually does, check the pump, you might be holding a diesel trigger.

This same principle was used in the 80s when we transitioned from leaded to unleaded fuel. Leaded fuel nozzles wouldn’t not fit in unleaded gas holes.

Start Your Lawn Mower in One Pull

If your mower is hard to start or runs rough, this secret is for you.

I get a lot of these secrets from my dad and he gave me this one last spring. My mower ran a little rough and it took a couple hard pulls to get it going. Within a few starts after this secret, it was starting with one easy pull.

The secret is pretty simple: use premium gasoline!

I know what you’re thinking, “I’m not made of money!” But, this is a very affordable experiment to try. In your car, it costs significantly more to use premium fuel, so you’re probably not going to use it unless you have a high performance car that requires it.  But, the fuel your lawn mower burns might only cost a few extra dollars per year for premium.

The benefits to your mower are as easy as 1, 2, 3:

  1. Starts easier
  2. Runs smoother
  3. Lasts longer

The proof is in the pull. Now that it starts easily and runs smoothly, I know it’s going to last longer and that’s worth a few more dollars per year.

The same applies to your car. If your car engine runs rough, you should give mid-grade or premium fuel a try. Your engine may sound noticeably better, idle smoother and start much easier too. If not, then it’s a waste of money.

In fact, the FTC says that premium fuel is a waste of money unless your car requires it or runs rough without it. If neither your mower nor car engine improve with premium fuel, then stop using it.
