Biodiesel and Alternative Fuel Analysis

Peak Petroleum provides testing and analysis of biodiesel and alternative fuels. We offer a thorough line of tests specifically designed to enable producers, distributors, blenders, and end-users to meet the industry standards outlined in ASTM D975, ASTM D6751, and the BQ–9000 accreditation program.

We have the practical experience, technical expertise, and state–of–the–art technology to handle your biodiesel testing needs. We know our customers' unique requirements at every link in the biodiesel supply chain –– distributors, producers, blenders, and end-users –– and our testing is custom–made to address each one of them.


The specification for biodiesel fuel blend stock - (B100) is ASTM D6751. This specification is comprised of 15 different tests. These tests define the required properties of all biodiesel fuel at the time and place of delivery.

Biodiesel F.A.Q

What is in Biodiesel?

Biodiesel is created with a chemical reaction by using natural oils, alcohol, later, and purification. The most common ingredients are cottonseed oil, cooking oil, soybean oil, tallow, and yellow grease.

Do I need to make any modifications to my diesel vehicle to use Biodiesel?

Maybe, If your vehicle was produced on or after 1934, you do not need to make modifications to it. It was a change to the fuel lines that allowed this.

Can I run Biodiesel in my gasoline engine?

No, biodiesel is only for diesel engines.

Is Biodiesel suitable for my engine?

Possibility, biodiesel reduces the wear of vital engine parts by having excellent lubricating properties.

What are the common issues with Biodiesel?

Fuel filter clogging, seals and rubber hoses degrade after a while, cold weather with thickening the fuel (can be helped by blending petroleum diesel to lower the gel point).

Does Biodiesel contain diesel fuel?

Biodiesel itself does not contain any petrodiesel. However, biodiesel and blends of petrodiesel are often sold as B20 (20% biodiesel, 80% petrodiesel mixture) and B5 (5% biodiesel, 95% petrodiesel blend).
