How to Reduce Marine Diesel Fuel Costs

Diesel engines tend to use less fuel than their gasoline counterparts, but extended cruising with a pair of high horsepower diesel beasts in the stern can burn through a lot of fuel.

Difference between Marine Diesel Fuel and Other Diesel Blends
Marine diesel fuel is not necessarily the same stuff that truckers and diesel pickup owners use to fill their tanks. Depending on the marina location and the output of the nearest refinery, marine diesel can be fuel specifically distilled for marine use or re-purposed on-highway, off-highway or heating oil. This EPA report also made notice of the significant differences in fuel obtained for commercial boating and shipping purposes and recreational marine use. Commercial use fuel consists of distillate blends aimed at reducing the cost and often includes a significant portion of unrefined oils. Recreational diesel fuels are more likely to be re-purposed land diesel with additives added for marine use.
Marine Diesel Production Cost Drivers
According to the Energy Information Administration, the cost of a gallon of diesel fuel breaks down this way: 62% is the value of the crude oil used to make the fuel, taxes are 18%, 5% is the refining cost and the remaining 15% is called distribution and marketing (profit to somebody). Diesel for marine use is not required to include highway taxes so the tax bite on diesel from you local marina is significantly less than at the truck stop. On the other hand, marinas can sometimes charge higher prices for ”distribution and marketing”.
How to Find the Best Marine Gasoline & Diesel Fuel Prices
Using the Marinefuel.com database I checked gasoline and diesel prices at marinas in Florida and northern California. There was a big spread between different marinas, up to a $1.00 in some cases. The cost of marine diesel fuel was typically 30¢ to 60¢ less per gallon than gasoline. Some of the difference can be attributed to lower diesel fuel taxes. My research revealed that in many states the highway tax is still included in marina gasoline but is not charged on diesel fuel sold.
