It was a peaceful day today, not much of anything going on, because apparently half the residents of Denver are up in the mountains somewhere which makes me glad I'm not.
I've got to have my truck inspected for emissions before the end of this month so I can get my new tag. Every summer I have to go through this just because my diesel truck is over 10 years old and is required to have a very strict emissions test just to get past Denver's goofy requirements. The only problems I've ever had with these tests is my diesel particulate filter, DPF, not meeting standards, so I've learned a few tricks to get it to pass that have worked so far.
The first thing I do is put some Lucas Diesel Deep Clean in the fuel tank and use the whole tank, this stuff is made specifically to clean the DPF. Then I make sure before I take it for the inspection that I get it on the highway and run it at highway speeds for at least an hour. This heats up the DPF and causes it to burn off some of the soot that builds up from stop and go driving, returning from a mini-vacation is a great time to do this. The last thing I do is on the day I take it in for the emissions test I get out my code reader plug it into the trucks Onboard Diagnostics Plug, OBD plug, and delete whatever codes have been thrown.
So far that has worked, but the best solution would probably be to not be a Denver resident but at the moment the benefits of that outweigh the difficulty.
