Can Heating Oil Be Mixed with Diesel?

In principle, mixing heating oil and diesel is possible and generally harmless for your heating system. Both products are chemically very similar, as heating oil and diesel are mineral oil products with comparable properties. The main difference lies primarily in their use and taxation: heating oil is dyed red to identify it as a heating fuel and to ensure it is not subject to motor fuel tax, whereas diesel is clear and used to operate vehicle engines.

Using Diesel as a Substitute for Heating Oil

In certain cases, for example if heating oil runs out at short notice and the next delivery is not yet available, diesel can be used as a temporary substitute to keep the heating system running. This is a common emergency solution and normally does not damage the heating system. However, there are a few important points regarding mixing and the associated costs.

Technically Unproblematic

Mixing heating oil with diesel does not cause damage to the boiler or burner, as the combustion properties are very similar.

Cost Aspect

Diesel is generally significantly more expensive than heating oil because higher taxes and duties are levied on diesel. For this reason, the permanent use of diesel for heating purposes is not economical. For the same tax-related reasons, it is also not permitted to use heating oil instead of diesel.
