2018 Mazda 6 DPF in Hot Weather
Hi!
I'm originally from the UK and I drove a VW Passat diesel with a DPF. I never had a problem with it because most of my trips were long motorway drives.
However, my company recently transferred me to the Philippines* and now I drive a 2018 Mazda 6 diesel with a DPF (SkyActiv 2.2l).**
My daily commute to work is only 10 km (6.2 miles) and because traffic here is really bad, my usual travel time is around 45 minutes. My trips here are 70% city and 30% motorway.
I know that DPF regeneration needs high exhaust temperatures. I'm usually stuck in traffic here but the weather is really hot (tropical country). Will the hot weather help with DPF regeneration?
Owner's manual says I should be fine if I regularly drive faster than 15 kph (9 mph), drive for more than 10 minutes, and drive when the engine is warm. Should I believe this?
*Interestingly, majority of BMW and Audi models here are diesel powered. Fuel quality is good here (Euro5).
**The company paid for the car but I will be paying for fuel, maintenance, and repairs.

The traffic wont help much usually they regen whilst driving at motor way speeds as you less likley to notice the misfire that burns the soot but good maintaince and a good drive every other week shpuld blow out the soot nicely

Ambient temp wont make much difference. The EGT ( exhaust gas Temp) needs to reach very high temps, maybe 300/400/500 degrees centigrade.
I know a Mazda BT50 with DPF will reach 585 degrees centigrade during a DPF burn off.
