Had a good sized load if split wood in my truck today. I reallyhatno idea how much it weighed but the wood was not full green so i guess about 2500 lbs. the wood was drier than I thought it would be.

Anyway, did a 25 min drive on hilly back roads in T/H mode and the diff temp was identical to driving unloaded. My new opinion..... subject to change... if tou have an HD truck, Unless you are towing 10,000 Lbs plus lbs frequently there is no need for an aluminum diff cover.

Unless tou just want the drain plug.. or you want you siff cover to look fancy.

Got a big heavy trail to test it with ?

I think you would more heat with a heavy trailer behind it.

I also wonder if it would take more miles to heat things up enough to see a big difference.

I will throw my temp gauge in my truck and check it out on my next trip to town.

I dont have a “heavy” trailer. I try my hardest to put everything in the bed. The only trailer i own has a max payload of roughly 6,000 lbs. i rent after that as i cant justify the cost of buying one.

Random tip:

When I got back from the latest trip where we hit the snow storm in the mountains in PA, my truck and trailer were CAKED with salt from the roads up there. I knew a regular car wash wouldn't do the trick, so I started thinking... there's a big rig (Blue Beacon chain) wash up the road. I called them and asked if they had the underside blaster. Yep... $6 and it blasted the ****! out of the underside of my truck & trailer. The paint is ceramic coated, so I don't take the truck through car washes, but they let me run it through for the underside blaster only. Went home and washed the shiny side of them both in the driveway. Check one out if you live in the rust belt!

Do you do your own ceramic coatings? Its a very neat coating. Iv only done acrylic coatings myself.

What is the Amsoil 0w40 operating temp? With the vii level you need to make that, it is essentially a 5w30 95% of it's life. Even your PUP mix with all that 0w40 ended up 10.9 or close right after 3k miles? That is an entire point less then what it can be for e a 5w30. Whatever the choice, Amsoil SS 5w30 is nowhere what you used to think about it. It is a low visc oil instead of a high visc oil.

The PUP mix (3qts 0w40 & 4qts 5w30) had a cst of 10.73 after 3300 miles. Far cry from the 11.76 (4qts [email protected] & 3qts [email protected]) it started out at per Pennzoils data sheets.

My PUP mix 50/50 of 0W-40 & 5W-30 has a cSt viscosity of 10.62 at 100°c after 2100 miles...much lower than I expected.

I'm thinking the magic number for keeping a noisy Hemi quiet is 11+cst@100C. I'm also thinking 7 quarts of PUP 0w40 is another good choice for a ticking Hemi because it should shear down to the 11.5 range fairly quickly. Plus the 225+ moly...

Nah, there's a guy on base here who has his own business and shop on the side who does it. The stuff is amazing.

I have 3 5-30 and 3 0-40 SS in my yuk right now. That along with the MoS2 quieted it down considerably. Different engine, but it did make a considerable difference from the straight 5-30 that was in it. Hard to say how much effect the MoS2 has on it, since I did them both at the same time.

I'm a simple guy and don't quite understand all I know about all this chemical stuff but I just have a hard time understanding how any of you can claim that brand X is so good or brand y is so bad when everyone is mixing different weights and then adding additives to it. You no longer have brand X or brand y. For me if I can't pour 7 Qts in and it work just the way it came out of the bottle then I'll look for something else. To each their own and it's you're truck so run what you want. I figure these big oil companies or blenders pay chemists big money to come up with a formula that works. My Hodge podge thinking I'm gonna dump this additive or mix these 2 weights could very well detract from original formula. JMO.

Well if the oil manufacturer say that it wont hurt a thing to mix viscosities if i want to create my own..... I believe them.

Look at the UOA on the 100,000 mile Ford Explorer I posted. Iv been mixing viscosities in that for some time and the wear numbers are excellent

What would they have been if you hadn't mixed?

I wonder what a new ram would look like painted up like the old D100/200? The Ram's lines are so much different though, I dunno...

I do think Chevy pulled the Cheyenne Big 10 makeover off pretty well though. The retro-esque rallies look great too.Chevrolet-Silverado-Super-10-conversion-01-720x340.jpg

Thoughts?

Just did an entier can of seafoam with the “s” straw through the throttle body with the i tentions of cleaning up the intake manifold.

Gave the truck hell for a good 2 mile drive after that and it is running fine. It was defanitly idling rough on takoff.

Hard to say how well it works. Now for the 10w40 redline oil change today.

I agree, but it would take a very skilled painter/designer with a keen eye for detail to pull it off. Everything is so curvy and round on the Ram in comparison to the D series, including the wheel wells. I didn't realize until now that their wheel wells used to be squared off like the GMs.
