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.

      Towing In Loose Gravel

      By JimCost2014 · Posted

      If what you are doing works, keep doing it:   4LO (Four-Wheel Drive Low) should only be used in extreme low-speed, high-torque situations such as deep mud, heavy snow, steep rock crawling, or extreme inclines/declines, and you must follow the correct engagement procedure to avoid drivetrain damage. Intended Use Cases Deep mud or snow where traction is extremely poor and you need maximum torque to get unstuck Trucks Only+1. Rock crawling on steep, uneven terrain forum.fullsizechevy.com+1. Extreme inclines or declines where you need to control speed and maintain traction solutionsphere.blog. Heavy towing in low-traction conditions (e.g., deep sand, ice) carclubsusa.com.

      Towing In Loose Gravel

      By rdonarski · Posted

      Hi,   I work a steep boat landing that has patchy blacktop going down the hill and soft sand/gravel at the bottom. Due to low water levels, it's not always possible reach the blacktop. I've had to help several people get out this year already and with fall coming, I'm anticipating more. I always use 4L. There was a gentleman there today with a 2500 HD (actually 2 - him and his son both have them) and they were trying to get his son's wake boat out. This gentleman swears that you should use 4H in the soft gravel. Says he was a farmer and you always use higher gear when stuck. I was wonder what your thoughts on this are? If I'm wrong, it would be good to find out before things get busy.

      Roll up bed cover experiences

      By Bill Lemmond · Posted

      Looking for feedback from users of roll up aluminum slat bed covers who have had it for more than 3 years. I prefer the aluminum slat style over supported vinyl covers due to security and the capacity to support a light load. The slight loss of bed opening when rolled up is not an issue. Presently have BAK Revolver the "industrial grade vinyl overlay" on mine is shrinking & coming loose at the rear and on both sides in addition to cracking at some of the folding joints. Truck lives outdoors in NC latitude. Can't justify the steep price to replace it with another one if that's the expected lifespan. Do you have a better alternative?
