EcoDual Inc. announced Version 2.0 of its MAX/SR Dual Fuel System and a new two-year unlimited mileage warranty.

MAX/SR 2.0 features a change in natural gas substitution rates with industry-specific enhancements to EcoDual's proprietary technology. Other key upgrades of MAX/SR 2.0 make the system more reliable, durable and lighter, while also decreasing installation time, emissions and maintenance expenses, says the company.
