I just tried Valvoline's fic plus intake valve cleaner. I can't say that I've noticed anything though. Of course I didn't let the tank run low either. :D

Well, that's sort of what I'm getting at. Are fuel injector cleaners really that effective? Or just a waste of money?

I use Berryman's B-12 Chemtool fuel injector cleaner once every 3 months or so. (sames folks that make B-12 carb sprays and racing additives) I have no scientific proof that it helps but it's cheap to do and I've never had a fuel related problem in any of my vehicles.

I've used B-12, Techron, Lucas and BG 44K. The B-12 I've been using in 1980 Silverado occasionally. In my '04 I've used Techron and Lucas. Just dumped a can of 44K in a few weeks ago, figured it couldn't hurt after 62K. I can't say any one is better than other from my drivers seat. Techron and BG 44K have excellent reputations. Techron and BG smell like they would work better. biggrin.gif

The only way I'd say they might be a waste of money is if you use them too frequently, such as every tank. That would be overkill IMHO.

Techron is magic elixir. It cleared up misfire problems on several vehicles I've owned. It even fixed my snowblower last winter.

I use a tankful at each oil change.

That Chevron/Techron stuff does work great, but everywhere I have seen it for sale it is always a lot more expensive then the other brands.

I like Valvoline Syntec Full-synthetic Fuel System Cleaner. Used it once and noticed a big difference. Used it again and didn't really notice anything the second time but it was probably because the engine wasn't that dirty anymore.

I dont know I'm skeptical about these products. The fuel injectors run at really high pressure. I cant imagine anything clogging a nozzle. I dont really know that much about the injectors in gas engines but I recently replaced injectors in an old Galion Grader with an International diesel engine. The fuel pressure I'm sure is higher in the diesel but the fuel had worn channels into the steal pre cup. in other words the fuel was under enough pressure to cut metal. I cant imagine what some snake oil mixed at such dilution could possibly do. I also wonder what it could do to all the damn sensors. I do have a "78 harley shovel head which was designed to run on 95 octane leaded high test. These engines are known to need valve jobs at 40,000 miles. mine has well over 50,000 dispite no lead to lube the valves. I use a cap full of marvel Mystery Oil when ever I remember.

Techron Is all we use in our fleet of Fords. Some of our Rangers Idle around all Day and Night and we started having Misfires caused by injector problems. After a 45 minute injector flush with motorvac detergent, The misfires are gone the fuel trims are back to perfect and the Engine is smooth running once again. I then put a bottle of Techron in the tank and ship it down the road. Now every 5000 miles when they come in for service they all get a bottle of Techron . We havent had any more problems since we started using it. Techron is the Only thing i can say definately works.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
