Are there alternatives to this type of oil?

If you rely heavily on oil but you’re looking to reduce your environmental impact, why not consider switching to carbon offset red diesel or even better, HVO fuel (hydrotreated vegetable oil)?

With carbon offset, red diesel is essentially the same fuel as 35-second oil. You simply purchase carbon credits for just a few pence per litre, which will allow you to fund carbon-reducing initiatives across the globe, effectively counteracting the carbon emissions you produce.

HVO fuel is a direct drop-in alternative to 35-second oil and can reduce up to 90% of your net CO2 emissions right away, as well as significantly lowering your NO_x emissions and particulate matter. Plus, it can be left in storage for up to 10 years, providing good maintenance and storage conditions!

The fractionating column image below demonstrates how crude oil is separated into component parts, producing various fuels for use in transport and industry, one of which is diesel oil, of which 35-second oil is a type.

What does 35-second oil look like?

It has a clear, bright and cherry red appearance as it has a red dye added to distinguish it from white road-going diesel.

The ‘second’ indicates a measure of hydrocarbon fuel viscosity and is articulated as the number of seconds 50ml of fuel takes to flow under controlled conditions through a set size orifice. This testing equipment is called the Redwood Viscometer.

The oil in the holding cup is heated to 40°C. Once the conditions are correct, time is started, and the oil passes through the orifice. Once through, the time is stopped and the time is recorded. The longer it takes, the thicker the oil and the higher the viscosity. Gas oil is one of the thicker oil types used in non-commercial heating appliances, which can vary from 23 to 35 seconds.
