Re: EGR Valve Question
I use Diesel Kleen with Cetane boost in the grey bottle all year round. I haven't had any turbo issues and it seems to run a bit quieter (if that's a word). Thats totally based on a finger in the wind seat of the pants sort of observation, I've never actually tested the decibels.
