Slang/metaphor to signify friendship and levels thereof.

Diesel: Friendly
Dieselness or Dieselhood: Friendliness


0-33%: American Diesel- Below 50 Cetane (New Friend - Regular Friend)

33-66%: European Diesel- Above 50 Cetane (Regular Friend - Good Friend)

66-100%: Biodiesel- Cetane Unknown but helpful to the environment. (Good Friend - Best Friend)

100% & up: Fuel Cell (like those prototype Hydrogen Fuel Cells. In other words, if the Opposite Sex is Fuel Cell towards you, they like you more than a friend.)

Fuel Cell is Heterosexual only. Homosexual love is so different it requires its own fuel! See Solar Power.

- Never, EVER spray Diesel Fuel on a person acting gasoline towards you!

- Even though it sounds like a quick & easy fix to a friendship, it will NOT work!

- In fact, their gasolinism will worsen, or worse- their stance towards you may sink to the abyss of being Jet Fuel!!

- This is only a slang/metaphor/analogy so please keep this in mind!)

Example 1: Hey Dane, why aren't you being Diesel tonight? Oh, DGray is possessing you again?? Dane, I know you're in there somewhere, so fight him out of your body!

Example 2: So Josh, how Diesel is your girlfriend?

Josh: She's more than that; She's pretty Fuel Cell, man!

Example 3: The most important part is- you survived. That's the most diesel thing you can ever do for us.

Example 4: That guy is acting a little TOO diesel towards you! Do you think he's showing a little... ...solarity?

Example 5: While I was on the phone at a gas station, when I saw a diesel truck pass, they increased my credit limit to $750.

However, I was at this gas station that didn't serve any diesel, so when I got done refueling, I saw a car rear-end another, which is a pretty gasoline thing to happen!

Diesel is not car fuel and oil mixed together, it's not a type of "gas," it is a lower-grade petroleum distillate used in DIESEL ENGINES which has a much higher flashpoint and whose fumes are non-explosive as opposed to gasoline's. Diesel engines use "compression-ignition" (the heat of highly compressed air in the combustion chamber) to ignite a very fine mist of diesel fuel. Used in heavy-duty trucks, generators, pumps, etc. for their higher specific torque (vs. gasoline) and greater fuel efficiency. Modern diesels are very clean, efficient, smooth, and quieter.
