Cummins is recommending fuel additives for its diesel engines for the first time. Diesel Kleen + Cetane Boost, left, is for year-round use. Diesel Fuel Supplement + Cetane Boost is for use when temps drop below 30 degrees F.Fuel additives usually bring to mind late night TV infomercials. But no less than Cummins, after substantial research and testing, has come out and endorsed two for its brand of engines.
The diesel fuel additives are Power Service Diesel Kleen + Cetane Boost and Diesel Fuel Supplement + Cetane Boost. Cummins says that the questionable cleanliness of today’s diesel fuel can in some cases warrant the use of these additives. The fuel problems cited by Cummins include poor lubricity, low cetane numbers, low temperature operability and injector deposits.
The advent of modern Tier 4 Final, emissions compliant engines make fuel quality critical. And this is no small issue and often the cause of unexpected downtime and expensive repairs. See our article about fuel quality here.
According to Cummins, Power Service Diesel Kleen + Cetane Boost used year-round cleans dirty injectors, prevents injector sticking, smooths rough-running engines, and can improve fuel economy.
Diesel Fuel Supplement + Cetane Boost, is recommended for use in winter when temperatures drop below 30 degrees Fahrenheit. It prevents fuel from gelling and keeps fuel-filters from plugging with ice and wax. In low temps, paraffin wax in today’s ultra low sulfur fuel can stop fuel from flowing through the engine and cause water to freeze in fuel-filters, blocking fuel flow.
The products are the first fuel treatments the Cummins has recommended in its history. Cummins formed a partnership with Power Service and will sell the products through Cummins distributors and Power Service retailers.
