10-minute warm-up? really

[Bluebird]

Met a new owner of an EcoD. I solicited TDR, of course. Told me the dealer stated: 10-minute warm-up in the mornings. Sounds fishy to me. My '93, 30-second oil>up, we go . We in San Bernardino California, yeah. Spring-time 365-days/year.
What you think? Patrick

Unless hes getting off a regen every few days, he's headed for trouble.

If it's really cold. You can let the grids do their thing ( if the ecos have grids mite have good plugs).
When I park Mule at night and it's 40s to 50s the next morning the grids Do not come on until it fires up. I let them do their thing for a minute then take off.
The engine will warm up faster if it has a little exercise.
