Any useful fuel additives?

[Paul Neubauer]

A gallon of kerosene in a tank will also serve to prevent gelling.

While it may work on old diesel engines, I would probably recommend not doing it on a modern diesel engine. A dose of the correct anti-gel additive will not void your warranty in the event of catastrophic failure from the pump sending metal throughout the fuel system.

Jet fuel?

That's a type of kerosene formulated for aircraft. The biggest difference is a higher flash point for jet fuel (for safety reasons). You can't just go to a pump and buy it, though.

Keep in mind that the purpose of these is to thin out diesel fuel that has thickened due to temperature. It is really not an additive per se, just a thinning agent that does carry with it some energy content.

Shell, Chevron or Mobil fuel with a bottle of Techron in the tank a week before every oil change.

Jet fuel?

I have about 75 gallons of Jet A1 behind the shop. Use it for my Ready Heater in the shop. One could use this in a truck, but I certainly would not mix it more than about 1:3

Used to get it where I worked. We would weigh aircraft after maint work. Needed to fully bottom drain the fuel tanks. This fuel was considered waste. Had a few hundred gallons at one point.

Jet fuel?

Different fuel entirely. Though similar it has no lubrication properties compared to diesel. It's more refined to remove waxes that prevent jelling at much lower temps. Has lower viscosity and a lower flashpoint compared to diesel. You could use it if required, but I wouldn't run it daily. You can use it in diesel / fuel oil heaters no problem.

What's a typical diesel fuel flashpoint? When I was an aircraft fueler in the Navy, we used Jp5, which was required to have a minimum flashpoint of 140 degrees F.

What's a typical diesel fuel flashpoint? When I was an aircraft fueler in the Navy, we used Jp5, which was required to have a minimum flashpoint of 140 degrees F.

Jet Fuels:

• Jet A: Minimum flashpoint is 38°C (100°F).
• Jet A-1: Also has a minimum flashpoint of 38°C (100°F). This is the most common jet fuel used globally for its cold weather performance.
• Jet B: This is a wide-cut fuel, which includes lighter hydrocarbons than Jet A or A-1, hence it has a lower flashpoint, typically around -20°C to -1°C (-4°F to 30°F). Jet B is used in very cold climates or extreme conditions.
• JP-4: An older military specification, now largely phased out in favor of Jet A-1, had a flashpoint around -23°C (-9°F).
• JP-5: A high flashpoint jet fuel used by the U.S. Navy for carrier operations, with a flashpoint of 60°C (140°F) or higher to reduce fire hazards on ships.
• JP-8: Similar to Jet A-1 but with military-specific additives; its flashpoint is the same as Jet A-1 at 38°C (100°F).

Diesel Fuels:

• No. 2 Diesel (Standard Diesel): Flashpoint typically ranges from 52°C to 96°C (126°F to 205°F).
• Winter Diesel (No. 1 Diesel): Contains more kerosene to prevent gelling in cold weather, thus has a lower flashpoint, around 38°C to 66°C (100°F to 150°F).
• Biodiesel: Depending on the blend (B20, B100, etc.), flashpoints can vary, but pure biodiesel (B100) typically has a flashpoint of 100°C to 170°C (212°F to 338°F) or higher, making it less volatile than petroleum diesel.
• Ultra-Low Sulfur Diesel (ULSD): Flashpoints are similar to No. 2 Diesel, generally between 52°C and 96°C (126°F to 205°F), but exact values can vary slightly due to formulation differences.

Makes me wonder if the drastically different flashpoint some fuels have would result in slightly altered combustion timing in a diesel (given the same injection timing)?

 

[HammaMan]

Given No 2's variance, probably not. I'd be most concerned w/ the lack of lubricity.

Hi, have a pretty long road trip (2000kms) tomorrow in my 2021 Lariat with 50,000km on it.

Worth it to buy a fuel additive on this tank for this extended highway trip? Thanks!

best additive is to add gas to the engine via your right foot. let it eat!!

We'd always use diesel to start our bonfires on the weekends growing up and sometimes you almost couldn't get that stuff to light with a torch.

Techron. You can get it at "Wally world" I prefer Chevron gas. better quality control than the Non-American companies. Plus they are one of the few majors that still make their own additives.
