EPA Mandates
The Environmental Protection Agency (EPA) mandates that all engines built after December 31, 2009 must
reduce the level of emissions exhausted by the engine to the following levels.
Nitrous Oxides (NOx) – 0.2 g/bhp-hr
Particulate Matter (PM)- .01 g/bhp-hr
To meet EPA guidelines, diesel engines installed in Tiffin Motorhomes PowerGlide chassis for domicile
in Canada and the USA use an after treatment system (ATS) with a diesel particulate filter (DPF)to reduce
particulate matter, and selective catalytic reduction (SCR) technology to reduce NOx downstream of the
engine.
Notice
Using non-specification fluids can result in serious damage to the ATS. It is extremely important that the
following guidelines be met for vehicles with EPA10 thru EPA2017 compliant engines, or damage may
occur to the ATS, and the warranty may be compromised.
