Does anybody else seem to think the same?
08 6.4 and I’ve used AMSOIL Signature and Rotella T6 before. I have reverted back to using Motorcraft synthetic blend 15w-40 and the truck seems to run a little quieter and smoother. I would be interested in trying a totally conventional oil if anybody has any thoughts or suggestions?

Engine starts and runs fine. No issues driving while it’s warming up or once it’s warm. But if I’m sitting at a red light or stop sign, when I hit the pedal, around 750 rpm, there is a slight squeak and goes away almost as soon as the truck gets above 750 and below 750 rpm. I shut the truck off lastnight to go grab a pizza and when I came back out and turned it on, there was no squeal when I started driving again. Maybe an exhaust leak too?

If I park my truck down hill and it rains, whenever I push the brake pedal, a bell goes off and notification comes up saying “Wiring Fault on Trailer” even when I’m not pulling a trailer. Can last for weeks until I’m assuming the water drains or dries from wherever it’s getting in to.
If I park the truck facing up hill and it rains, I don’t have any issues.
Anybody have any thoughts as to where I should start looking for the source of this issue?
I’m going to start with the plug(s) itself but am wondering if anybody else has had this happen to them.
