What type of diesel do you use?

I’ve driven diesel cars for 25 years now.
Never had any issues with gelling etc.
The older car ran fine on pure veg oil.

For the last 8-10 years I’ve used Costco premium diesel as it’s cheaper than local garage.
Two times a year I add an injector cleaner.
During the winter I add a cetane booster.
In my opinion it helps my car, start better, run quieter & smoother , drives better when cold.
Costs about £1.50 a tank.

Newer car alter the way they run depending on what fuel you use, so booster do not work as well as they do on older cars.

I use the type that comes out of the black pump at my local Texaco.

And I stay away from 'premium' fuels & their premium pricing.

Grade 1-D (Diesel #1): A lighter, more refined fuel suitable for very cold weather due to its resistance to gelling. It burns faster, offering less fuel economy but better cold starts.

Grade 2-D (Diesel #2): This is the most common, year-round diesel fuel used in most cars and trucks. It is heavier than #1, provides better fuel economy, but can gel in extreme cold.
Grade 4-D (Diesel #4): A heavy, thick fuel used for large, low-speed engines like marine vessels or industrial equipment.

I have no idea, perhaps I should find out, does it state this info at the pump?

Is there a type 3?

As already pointed out, these are American grades that come under the Advanced Standards Transforming Markets specs of D975.
And no, there is no Grade 3.

All our diesel is produced under the European Committee for Standardisation specs of EN 590.
This does have standards for "Winter diesel".

These winter standards are broken down into two different groups each with there only classes and sold in different zones.
Europe covers quite wide range of climates, some are extremely cold like Scotland (only joking, honest)

The two basic zones are Temperate and Arctic and the fuel will be quite different between the two between October/November and February/March.

The arctic version will have a much lower viscosity and it's cloud point (the point particles in the fuel start to turn solid and separate out) will be somewhere between -22 and -44°C depending on the class.

The very low temp class 4 of arctic diesel tends to lose a few cetane points, but it's not usually a massive drop.

For temperatures that are lower, another strategy is needed.
This usually involves heated garages, fuel and/or engine preheaters and once up and running, not switching the engine off until it's back in the heated garage again.
