Does PS Diesel Kleen do anything?
I've used it sporadically in the past with no real results.
I've been using Opti-Lube (Summer Formula) and it quiets the injector clatter. I will keep using it for that reason.
This trip - from CA, through CO, out to Iowa, onto the Jackson meeting and back to CA - I've been using both Opti-Lube and Diesel Kleen. I commented to my wife (on the phone) that the van was running quietly. Quieter than ever it seemed.
About 600 miles ago I ran out of Diesel Kleen and continued on. After one fillup, 300 miles later the van was noticeably noisier!. Stopped at WallyWorld and picked up some some Diesel Kleen, put in 8 ounces and within 10 miles the engine had quieted down.
I'm a believer.
Opti-Lube quiets the injectors and I like that and will keep using it. Diesel Kleen quiets the diesel clatter. Together they make it a more enjoyable ride.
Don't get me wrong, the engine still rattles like crazy when cold, and still has plenty of rattle below 1500 rpm. But, at higher rpm's it is a totally different beast.
I now have a new routine - 10 ounces Diesel Kleen and 2-3 ounces Opti-lube at every fillup (approx. 30 gallons).
