Refined Engine Oil a Critial Link in Fleet Sustainability

When it comes to offering contributed articles, I follow some of the oldest writing advice around: write what you know. And, with 30 years in the business, it’s safe to say that I know a little about the automotive and trucking industry.

Today, fuel prices are at an all-time high and are trending up; the accelerating conversion rate of fleets to natural gas serves as an encouraging sign for the energy market. Not only does fueling cars and trucks with domestic natural gas help reduce US dependence on foreign oil, but the use of natural gas has been shown to reduce greenhouse gas emissions by a 23 percent margin. This is great news for the environment. For example, consider an 18-wheeler that uses up to 20,000 gallons of fuel per year. Replacing only 100,000 of these trucks with those powered by natural gas would immediately cut our consumption of diesel fuel up to 2 billion gallons, per year. Likewise, converting just one truck from diesel to natural gas is the equivalent of taking as many as 325 cars off the road in terms of pollution reduction.

For many fleet operators, achieving a clean, green operating profile is certainly a key objective, yet there are also less discussed – but equally important — economic considerations at play. Gladstein, Neandross and Associates, LLC (GNA), one of the nation’s leading consulting firms specializing in emission reduction and energy and transportation policy, has been involved with a large number of natural gas vehicle (NGV) projects. GNA’s chief executive officer Erik Neandross says that the company has seen real world NGV fleets demonstrating fuel costs savings of 33 percent versus diesel options. That’s huge.

But with all this excitement circulating around the energy security, environmental, and economic benefits of NGVs, it’s easy to forget that there’s still a petroleum product circulating in natural gas powered trucks: engine oil.

Each year, the US produces approximately 1.3 billion gallons of used engine oils, only 20 percent of which is re-refined. With recent technological developments, leading scientists and engineers have honed the capability to “recycle” used engine oil and restore it to “better than new” quality. That’s because used engine oil is actually a higher quality feedstock than crude.

To speak technically, engine oil is approximately 85 percent oil and 15 percent additives (detergent, anti-foaming stabilizers) and it is the latter 15 percent which breaks down by design as contaminants accumulate over time, necessitating oil changes. As the oil molecules themselves retain their chemical compositions, spent engine oil simply needs to be refreshed (stripping away contaminants and the worn out additives), re-refined into American Petroleum Institute (API) approved base oil, and then infused with a fresh additive package, to transform what was once thought of as a waste into a top-grade lubricant product.

For NGV fleet operators, re-refined engine oil represents a critical link towards taking sustainability efforts to the ultimate level. From an energy perspective, the average 12 quart oil change using re-refined oil helps spare 60 barrels of crude oil from being either extracted or imported. As a process, re-refining used oil takes up to 89 percent less energy and produces up to 65 percent less environment-impacting emissions than refining crude.

But above all, re-refined oil can be considered as a performance driven product that offers a number of economic advantages. To name but a few: typically higher total base numbers (TBNs) for long-term protection, reduced engine wear, extended drain intervals– all leading to less oil consumption and better fuel economy. For fleet operators, this isn’t just saving on the margins. Investing in re-refined engine oil offers sizable returns when it comes to maintenance costs and keeping care of multi-thousand dollar pieces of machinery.

It’s an exciting time to be in the automotive industry. It’s exciting to see new products and new technologies power our cars and trucks, but frankly, it’s more exciting to see a veritable revolution in outlook among fleet operators. For perhaps the first time ever, decision-makers are realizing that environmental considerations and economic considerations can be fused, rather than weighed; that what’s good for the planet can also be good for our bottom-lines. Helping the environment can help enterprises.

One thought on “Refined Engine Oil a Critial Link in Fleet Sustainability

  1. Interesting article with interesting implications. NGV technology is not all that new – NGVs have been around for quite awhile. Why then has it taken so long for fleet operators to realize that there are significant financial gains to be exploited by switching? I understand that the relative price of NG vs diesel has fluctuated, and that it currently favors NG by a large margin; but surely savings by switching could still have been realized prior to just now. Lack of awareness of the opportunity among fleet operators no doubt plays a large part in the answer to that question.

    So now consider other questions. Why aren’t large numbers of building owners doing energy efficiency upgrades, if they will save money by doing so, and attract more tenants with higher rents? Or why aren’t more individuals and corporations opting to put solar on their rooftops, by using the new financing mechanism of third party ownership? Or why aren’t more people switching their family vehicles from gas-guzzling models to higher efficiency ones? Or why aren’t even more wind tubine projects being pursued by utilities, when the fuel to run them is free? All these actions represent significant financial gains for the company or individual taking such action. Again, surely lack of awareness plays a large part in the answers.

    This sudden realization, and subsequent mass action, by trucking fleet owners; might be duplicated in other venues. While it is frustrating to watch so many energy efficiency and green energy opportunities continuing to be relatively unexploited; one can hope that similar mass actions might well materialize.
