how to check rail pressure bleed off? the noise that I have is cyclic and I guess it depends from fuel viscosity/fuel temperature. I think that noise is coming from needle amp return valve. I can hear that noise when engine is idling . at higher rpm the noise disappears.

I tried a jug of Stanadyne Lubrication this week. Large enough jug to do three tanks. Don't know if it's a coincidence but I never noticed my truck doing a regen all week. Maybe I missed it. Normally at the current temps I would have seen two or three for the week. But I didn't notice any.
I use a Scangauge to monitor the DPF, DOC temps and NOx. -

And certainly a lot of worse ones. -
I am still on stanadyne . I add 4oz every 100 g of fuel. engine runs smooth and less regens I see. what else we can try ? do you consider any other product? say the name and i'll try it.

Looks like Optilube summer blend has higher Lubricity and lower cost, but I can't buy it anywhere around Saskatchewan.
Stanadyne I can buy in Saskatoon and yes, my truck seems to like it too. Seems quieter and less regens too.
