You might as well ask a magician how the trick is done as to ask a blender what’s in the bottle.

OK, but what's in the box!?

Yes 300K is the goal. Will I make it?  276K isn't that far off so yea, I already did.  That would make 3 units you know of and yea, that would make me somewhat of an expert on this piece of junk. Stil

The 2.5 is pretty good except for it's Achillies heel (same on the 1.4T, 1.5T and 2.0T).  The camshaft driven vacuum pump.  If the pump fails seen them jump time or break the end of the cam they are o

The pendulum is starting to swing back from these low viscosity oils, I think. Maybe CAFE softening up a bit or the amount of warranty claims is becoming unsustainable. Early 5.0 Fords called for 5w20. They quietly bumped it to 5w30 for 2021. And if you add the factory supported Whipple supercharger? The spec becomes 5w50.
 

Waiting to see if GM will follow suit. Even their non-defective “healthy” 6.2s have no business running 0w20. Not at the oil temperatures I saw on my stock 2019 and not at these OCIs either. In fact, studies have shown increased piston ring and bearing wear when the HTHS viscosity is at or below a typical hot SAE20. And the handful of 0w20s that actually are stout enough in HTHS are niche, expensive and carry no approvals. So for practical purposes they don’t exist.

CAFE is no more.  CARB has been neutered.  Waiting on the passage of HR4117 to cement these changes.

You’ll be waiting a long time. The bill isn’t out of introduction phase in the house.

It was included in other legislation that was to be voted on this month but was removed for reasons forgotten by me.

It’s from Facebook so probably a big “if”…but “if” this guy is telling the truth about the oil change interval, that leaves the quality of the oil used, and the viscosity of said oil as two big question marks here. Even the non-wiped lobes on the cam look terrible.

Not saying every truck is eating a cam at 67k miles but I’ve seen enough low mileage failure cases to be highly skeptical of generic 0w20 being run in any full size trucks.

This is what you were seeing in Your analysis when I saw it earlier. How’s the reports now?

Instead of politics let’s discuss policy and what car makers DO. NOT WHAT YOU WANT IT to be.

Improvement with miles just as one would expect. Oxidation and Nitration look stellar for this oil which has nearly a 10 nitration background. Oxidation, ditto, near VOA values. Good VI retention. TBN is happy on E85 and begging for some breathing room. Oil is not being stressed. Fuels is what I would expect for the fuel used vs the fuel that was. Identical to my results.

Boys we aren’t making meth or spraying nitrogen on fields. No engine oil

has 10 abs units of nitration reading. You are nuts.

Once again catch you “skinning the cat of truth”. Firmly call you on your online BS. THAT ain’t  10 abs. So you are an order of magnitude off. Geebus

I've supplied numerous STLE and SAE articles and equipment vendors instructions on this topic. You can't wish a thing to be true. I'm not suppling more TRUTH from YOUR PEOPLE for you to ignore and confuse people with. 

 

 

Nitration levels are all over the map. 2 minutes googling others VOA samples. Background matters. It matters to the STLE and the SAE and to the people that make the instruments that measure it. You call me a liar and a fool and whatever else come to mind but it still won't make you right. Make you opposed to your own craft. 

 

Produce ONE single credible source that agrees with this fiction and I'll give it a second look. But until then...fiction it is.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
