Tip for all you newer diesel owners. Wrap up your exhausts with heat tape. Diesels don't have as high exhaust temps as a gasoline engine does so wrapping exhaust post turbo won't hurt anything while also keeping catalytic converters and DPF's hotter so you end up needing less fuel to regen and you also keep things less clogged with suet.

The dpf regeneration burns fuel. Ford specifically says in their early dpf trucks that regeneration cycle can burn 17L of diesel fuel. What a waste.
