Over the years, there have been many changes in the diesel industry, many of which have lead to a much cleaner environment. However, fuel mileage will vary due to truck configuration, duty cycle, road speed, and environmental conditions. From an engineering perspective, there is an inverse...

Cummins, as a technology leader, has access to a broad range of technologies; however, we are unable to discuss future products at this time. Thanks for your question.

At Cummins, with our broad range of integrated technologies, we have the ability to choose the right technology for the right market. As with all of our products, we conduct extensive testing and validation to ensure that our product is the optimum solution for customers in each market...

Cummins appreciates and values customer input. In fact, serviceability is one of the key considerations in our development.

In the commercial market, fuel economy and low cost of ownership is most important. In order to provide optimal cost of ownership in this market, we had to have a lower rating than the pickup.

We see a lot of high-mileage Ram trucks with Cummins power, but we always love to hear about it. Thanks for sharing!

This is a great question. Thank you for asking. If you must idle the engine for extended periods, the net zero / net reducing idle function launched in production and in service calibrations in early 2008 is an important feature. This feature offers expanded capabilities in managing the soot...

ULSD fuel was developed to be a backward-compatible replacement for the outgoing Low Sulfur Diesel fuel. In general, additives are not needed. Thanks for the question.

For fuel filtration on the later 5. 9 and 6. 7's, the answer is yes: 1. Mopar is offering a new severe-duty filtration kit that includes a 15-micron filter that offers expanded water-stripping capabilities. This kit was developed by Chrysler speficially for the Ram Heavy Duty trucks...

Question 1 - We have been working non-stop to refine the Cummins 6. 7-L Turbo Diesel for the RAM Heavy Duty since its launch. This has included many controls and diagnostics enhancements, which have been made available to current 6. 7 owners through the latest ECM flash updates. For the new...

I appreciate your question. There are no changes in the calibration that would cause the observed change in fuel economy. What you are seeing is likely related to how the fuel economy was measured, or a mechanical factor (change or issue). When comparing fuel economy, please bear in mind...

As stated earlier in this thread, we do love to see you work our engines, but they are validated for all representative duty cycles. Drive it to suit your needs and maintain it well, and it will take good care of you.

The next round of diesel emissions regulations are still being defined, and we are not really at liberty to discuss future products. However, you can rest assured that we are already working on 'what comes next'. :)

On behalf of the entire Cummins team, I wanted to thank everyone at TDR, both the members and the staff. We really appreciate the opportunity to hear your feedback and answer your questions, so this has truly been a great evening for us. We will continue to work through any posts we have not...

We have gone to great lengths over the last 2-1/2 years continually refining and enhancing the Cummins 6. 7-L Turbo Diesel for the Ram Heavy Duty truck. If you are ready for a new truck, buy a Ram Heavy Duty truck with the Cummins 6. 7, and be confident that you have chosen a great truck with a...

The MY2010 pickup is not equipped with the SCR (Selective Catalyst Reduction) system which requires Diesel Exhaust Fluid (DEF). But in reference to your question the DEF price will be market driven. The DEF prices at the pump are estimated to be comparable to the price of diesel fuel.

The reported emissions results are a composite of the base engine emissions and emissions during the regeneration process-so the net effect is a much cleaner product. Thanks for your question.

It is important to understand that Cummins and Dodge invest significant resources in tuning for the best overall economy, performance, durability, and emissions compliance. It is sometimes possible to make trade-offs in one area for gains in another. Unfortunately, altering this balance can...

Cummins has the capability to choose the right technology for the market. For the Chassis Cab product, we determined that SCR was the optimum solution for duty cycles required in this market. However, for the pickup product, we already had a proven combination of advanced technologies that met...

We have validated the Cummins 6. 7-L Turbo Diesel in all representative duty cycles. That said, we love to see you work them. While they are capable of cruising around town, you will enjoy the greater capabilities this package when towing or hauling a load.
