Is diesel still good after gels?

Diesel fuel is prone to “gelling”, a term used to describe the crystallization of waxes in diesel fuel in extremely cold weather. This gelling can prevent fuel flow to the engine or clog fuel lines/filters, making it impossible for diesel engines to run.

Can you use diesel after it gels?

If your diesel fuel has already started to become too thick, you can use Dieselpower! D-Solve De-gel to return it back to normal. Just pour it into the tank, and then be sure to add Dieselpower!

Will gelled diesel return to normal?

While gelled fuel sounds bad, the good news is that diesel fuel will return to normal as soon as the temperature goes back up above the gel point. Pushing a vehicle into a garage and leaving it for a few hours is typically all that is required to fix the gelling problem.

What happens to diesel after it gels?

Gelling diesel is caused by wax particles forming in the fuel. The diesel literally freezes. The big issue with this is that the fuel then can not flow through the engine and fuel lines properly. Not only will the machine be inoperable but the fuel lines and engine could potentially be damaged if this happens.

How long does diesel anti-gel last?

Gelling: Situations where the fuel literally turns to jelly are fairly rare. Gelling occurs when the paraffin wax in diesel solidifies because of a drop in temperature, and the temperature of the fuel generally has to stay below something like minus 10 degrees F for extended periods, like 48 to 72 hours.

Explaining Why Diesel Fuel Gels and How to Use Diesel Winter Anti-Gel

Will gelled diesel thaw?

Use to liquefy frozen or gelled diesel fuel caused by wax formation or ice crystals in cold weather. Quick-Thaw will completely thaw the entire fuel system in about 20 minutes when used according to directions.

Can you put too much anti-gel in diesel engine?

Too Much of a Good Thing Can Be Bad

If you're losing lubricity, don't over-treat. Adding too much of a lubricity improver can react with other various contaminants already in your fuel to cause a different fuel problem—clogged filters.

How do I know if my diesel fuel is gelled up?

How do you fix a gelled fuel filter?

Gelled Fuel in The Fuel Tank:

Remove the fuel filters and fill all fuel filters with a mixture of 50% Diesel Winter Rescue and 50% diesel fuel. Reinstall the fuel filters and then start your engine. Let your engine idle to warm up the fuel system and clear any remaining gelled masses.

How do you unfreeze diesel lines?

The easiest method is allowing the fuel line to thaw itself by bringing the vehicle somewhere heated. Obviously this can be difficult since the vehicle won't start and you'll probably have to push or two it to a warm garage, but if that doesn't work, you can also bring the heat to the vehicle itself.

How long does it take to Ungel a diesel?

It may take an hour of idle to thaw the entire line from the fuel tank, to the filter, to the injectors. Fuel Additives: There are now fuel additives that can provide an easy, low cost, and no-hassle solution to prevent gelling; one that any vehicle owner can do on their own.

Will diesel gel at 20 degrees?

At this stage, the fuel solidifies so completely that it can no longer flow at all (what we refer to as pour point). It's important to note, however, that diesel gelling only occurs at very cold temperatures, below 10°F (-12°C).

How cold does it have to be for diesel to gel?

Diesel fuel gelling has the potential to occur when temperatures drop below 32 degrees Fahrenheit, although the exact temperature it happens at will vary from fuel batch to fuel batch.

Does diesel go bad?

Stored diesel used to last for years – nowadays its shelf life is measured in months. Diesel fuel eventually goes bad, that's just a fact. Three things speed up the natural process of good fuel gone bad – water, air, and warmth.

Do gas stations add anti-gel to diesel fuel?

Diesel fuel anti-gels are simply added to the fuel (just drop it in the fuel tank). Anti-gels drop the freezing point of diesel fuel so that it is less likely to freeze in cold temperatures.

Do I need to change fuel filter after gelling?

It should not have any affect on future gelling or waxing issues at all, unless you have a full tank of gelled fuel *which would plug up a new filter in a hurry too.

Will block heater prevent gelling?

The block heater won't help with gelling but it does make cold starts far easier. Mine hates the cold and I always use the block heater in winter.

What causes diesel to gel up?

The Cause of Fuel Gelling

Gelling problems are typically caused by the effects of temperature on paraffin, a component of diesel fuel. Paraffin waxes are combustible, adding power when burned in the engine. However, when temperatures drop, diesel will start to solidify.

What temperature do you plug in a diesel truck?

A general rule of thumb is to plug in your engine block heater when the weather reaches -15° C or lower, just to be safe. If you drive a diesel vehicle, you may need to plug in the engine block heater before temperatures drop that low.

How often should I use diesel additive?

Our recommended Year-Round Maintenance Schedule is: Every time you fill up: If temperatures are above 30°F, add Diesel Kleen +Cetane Boost (silver bottle) for maximum performance.

Which diesel anti-gel is the best?

Diesel Extreme is the best additive in the game. This one adds seven points to diesel's cetane score (which again improves the fuel's combustion performance), and it cleans and lubricates injectors and other critical fuel system components. Diesel Extreme also helps remove excess water and contaminants from fuel.

Can diesel freeze while driving?

The fuel tanks can actually gel while driving. Diesel fuel gelling happens when the paraffin usually present in diesel starts to solidify when the temperature drops. To help prevent this from happening, it is important to always treat your fuel system with a reputable anti-gel additive.

Is it bad to cold start a diesel?

Myth #2: Diesel engines won't start in the winter.

“Today's technologies for cold-start are very effective,” Ciatti said. ​“Modern diesel engines start in cold weather with very little effort.” The problem is that diesel jells at low temperatures. Below about 40°F, certain hydrocarbons in diesel turn gelatinous.

How long should you let a diesel engine warm up?

As a general rule of thumb, if it is below zero degrees Fahrenheit, you should allow your engine up to seven minutes to warm up. If the temperature is between zero and fifty degrees, the warm-up period should be three to five minutes. Over fifty degrees will only require one or two minutes to warm up.

What's the difference between #1 and #2 diesel?

Diesel #1 is also known as winter diesel because it performs better than Diesel #2 in cold temperatures. It has a lower viscosity and is not prone to gel in freezing temperatures. Most stations offer a premium Diesel mix that is blended for local weather conditions. Diesel #2 costs less at the pump.
