When filling up, you basically have two choices: diesel #1 and diesel #2. The different grades reflect the content of cetane in the fuel, which is the volatility of the formula.
Grade #1 is generally more volatile and flows more freely, which causes it to work well during winter.
Grade #2 is more viscous and lubricating. Vehicles that use this variety benefit from lower operating temperatures, extended rpm, and enhanced torque used to pull their loads. The benefits that come with this grade allow for increased MPG and extended maintenance life of the engine. Diesel fuel #2 is recommended for general highway use.
Winterized varieties of fuel are a blend of diesel, light distillates, and kerosene. Using winterized types often results in reduced fuel economy. Some diesel engine manufacturers warn against using any additives.
For whatever strange reason, my Hilux has always delivered its best fuel mileage running winter diesel in winter conditions. I distinctly remember recording 6.9 L/100 km one time in the dead of winter in icy conditions. That's better fuel economy than an older Rav 4.
I do use a diesel fuel additive, but how does that explain how I get better mileage using winter diesel?
I never bother searching for expensive diesel #1, although I know of a couple local retailers' that offer it. The diesel additive I use contains a cetane booster, so there is no need.
I filled up the other day only to discover that diesel prices here had suddenly increased .35 cents/liter........
