NC KS | Best thing that ever happened to lessen city smog is updated buses, delivery trucks that have something besides a 2 stroke Detroit in them. I like L10 Cummins but they could smoke bad especially when cold.
Our oldest son was in China on business. Smog there is worse than any USA city.
Delete services wouldn't be in such high demand if the pollution controls were reliable. Most modern diesels (except pickups) don't get deleted if they are running good. I would guess a diesel engine built in the last 10 years runs very clean without egr and def. | |
