I was filling up my truck yesterday 12/26 in Dubuque, IA. The Kwik Start had E85 priced at $2.99 and 87 octane (10% blend) priced at $2.97. I never thought I'd see the day where ethanol was more expensive than regular fuel. Just thought i'd share with everyone.

Wait until about May and if its true what they are "speculating" E85 will be down around $2.65. Only time will tell.

I guess it depends on the amount of government subsidy on E85. I'm no expert but from what I understand the only way E85 can be cheaper than straight gas at current oil prices is subsidy?

 

I checked the % ethanol in my 93 octane in the truck (by reading what the truck computer says) and got 3.9%. The pump says contains "up to 10%". I wonder how accurate the truck % ethanol calculation is?

What are you talking about? I'm not aware of any way for the truck to tell ethanol content without a scan tool

I read the parameter out of the ECM with a Diablo Trinity through the OBDII port. What I don't know is how the truck measures or calculates % ethanol.

Read the refueling events sticky. Newer models play with ignition timing to determine ethanol content or something. Interesting about the Trinity being able to pull that data.

It should be pretty accurate. I know they cut back the ethanol percentage during the winter months on E85. I guess they could do that for the 93 as well.

The minimum ehtanol content for E85 is 70%

ethanol is under huge amounts of heat around here(we have i believe 2 or 3 ethanol plants)

 

the one closest to me was fined hundreds of thousands in fines for pollution and enviromental hazards...

i just finished running a tank a bit of e85 through the truck. e85 was 3.17, 87 was 3.67, 93 was 3.87. ill be going back to 93 i think. the e85 doesnt last very long in these trucks. feels like im gonna get about 100 miles less or so to the tank. not worth running

You typically get 25% less power/MPG. It's another silly idea like CFL's. Both are NFG, yet somehow got gov't approval, and marketed that "you'll save the planet by using it".

I don't know if I'm misunderstanding your wording but saying E85 has less power is wrong. It has less specific power but the truck will make more overall power running E85.

Less MPG yes....but not less power. E85 has higher octane (around 103) which gives an engine more pep and response. I run e85 fuel almost exclusively in my truck and it feels much more sluggish when running regular gasoline. Nobody ever said it would save money, but it is made locally and burns much cleaner than other fuels.

What if you get 25% less mileage but it costs 30% less? :dunno:

 

Would you buy a fuel that cost 30% more than gasoline but only gives you 25% more miles? If so, I have a business opportunity for you . . . :jester:

      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.
