Running out of DEF won't damage the engine as it's only a treatment for exhaust gasses. The ECM is programmed to progressively limit the trucks speed when DEF runs out. I have heard of some tunes turning off the DEF system. That would also appear to make it possible for someone to turn it off...
I use both:
-Fuel: Power Service and/or Howes. Mainly for HPFP lubrication - it needs it, also raises cetane for better combustion.
-Oil: Lucas synthetic oil stabilizer. Extra lube/protection of main bearings - also needs it. Plus, previous experience with Lucas saving rebuilt engine from...
Now that USPS finally got around to delivering the new controller (It sat in OK City for a week), I can finish this story.
There are two P/Ns for the controller. The original (superseded) is 68149041AB. The new P/N (what I got) is 68282916AA. After installing the new unit and reinstalling...
Recently, I drove home and parked - everything normal. The next morning, it wouldn't start. Normal indications, but when cranking, it would try to light off a couple of cylinders then just spin. That weekend, I connected my code reader - no codes. Fearing the dreaded HPFP failure, I pulled...
I'm thinking that, while your truck was in, the dealer flashed your ECM with the latest malware, er, I mean, program. Ask them if they did that, and if so, my recommendation is: Nod, say "ok, thanks", leave, and go get yourself an aftermarket tune.
Unfortunately, it does sound right. The tone wheel is sandwiched between the flex plate and the crankshaft. The trans has to come out to access it, that's why it's so expensive. This happened to me a few years ago. There is an ECM update available (dealer) for this. Essentially, it tells...
I get Wix oil & air filters and MicroGard fuel filter (made by Wix) from O'Reilly, and Rotella T6 from Walmart (about $27/gal). I use Lucas synth oil additive which I also get at Walmart. Cost is about $100 with the Lucas.
Hello,
I have a 2015 w/ 172k on it. Here's what I do/ have done:
-SofaKing stage 1 tune
-Oil changes at 7-8k miles w/ Rotella T6, Valvoline Premium Blue, or Delo full synthetic
- Been adding Lucas synth oil additive since purchase @ 26k mi (2gal oil, 2qt Lucas)
-Always, always, always use...
The main thing is to drive at constant freeway speed for 30-45min to get the DPF up to temp where it can burn off the soot. The SCR will also clear with heavy footed acceleration, once the DPF flows better.
Properly seating the two connectors likely solved the root issue(s). Try driving the truck out on the freeway to get your EGT up to where the DPF can burn off soot. Driving up into the mountains (if available) works, on the freeway towing a trailer, engaging "Tow/Haul" mode, or using the shift...
