I was in a discussion not long ago over the energy used as measured by fuel consumption between a warm summer day and a cold winter day. Youtubing I found these videos. Pictures and a thousand words sort of thing. -40 C is also -40 F. -35 C is -31 F for reference. Last year we set a record in my local at -30 F. Happy me I had a pan full of 0W* in her that day. Now this video does not show summer to winter but shows rather 0W to 5W to 10W to 15W to W30 straight weight at the same temperature. This is a part two to this series regarding other motor oil, transmission and diff fluids and greases. 

 

Pay attention to the difference in flow between the multi-grade low number. e.g. 0W30 The upper number in not in play. e.g. 0W30 When moving from video to video be careful to note differenced in points of reference so you don't get confused. Take note between Syn, Semi and Conventional of the same lower number v temp. These differences are base oil driven NOT pour suppressant driven. 

 

I'll do a separate post on some interesting personal observations Pepper has given me. 

 

 This one is Full syn v semi syn

Some of these are better than others This includes Walmart oil

 

What would a post be without AMSOIL

Mobil-1 has never done me wrong and helped to even clear up some cold start knocking on some 5.3 and 4.8L V8s from 99-06.  I have never tried Amsoil before but I do believe it is a solid product.  So using Amsoil and Mobil-1 in cold situations I would feel comfortable with.  I'd love to see some of the other brands out there and how they compare in the same test.  The next big test would be to see how the oils hold up over extended drain intervals.  Used in same engines, under same exact conditions, using same filters.  And then testing the premium filter brands out under extend drain intervals.  My goal and what I like to see for my diesels is 10,000 mile oil and filter changes.  I will be using full synthetic proper diesel 15w40? for my 2018 Duramax with 15,000 miles on it, and will be using premium oil filters such as NAPA Platinum, (wix) RP extended life, Amsoil Ea, Bosch Premium, Mobil-1 extended performance, Baldwin HD, K&N Performance, and of course AC Delco Pro.  But perhaps these have already been examined over at bobistheoilguy?  thoughts?

Not telling you what to do Colossus. Making a suggestion. If I wanted to go 10 K mile OCI's on any motor I would use Amsoil especially if you're planning on keeping it for a while.

 Amsoil Heavy-Duty Synthetic Diesel Oil 15W-40

Link https://www.amsoil.com/p/heavy-duty-synthetic-diesel-oil-15w-40-adp/?code=ADPTP-EA

$5.66 a quart for members and a 2.5 gallon jug.

Mobil 1 performed well in these test didn't they? 

 

What I had hoped for with this wasn't to show anything about brands of oil as much as selecting the right front number for the coldest temperature you expect in your location or situation. We set a new record low as I mentioned before last year, -30 F, that would have left any 5w or 10W solid or near enough so as to not pump well for minutes. Two months a year it gets that cold here. 

 

I also hoped that one would notice that Synthetics V Semi Synthetics V Conventional fluids even at the same first number vary quite a bit EVEN at the SAME first number. 

 

Personally I was surprised and impressed with the natural gas based 'ultra' Pennzoil/Shell products for cold flow. 

 

If you compare what the ESSO videos show with you favorite brands product data sheets pour point, cold pumping numbers you could develop a feel for the data that gives one eyes into the crankcase on a cold day. Just a thought worth thinking.

Speaking of cold weather, let's not forget to be thankful for synthetic gear oil in this day and age. Back in the day when I lived in eastern Wa. state that sees it's fair share of winter weather, I had an 84 K20 HD camper special with the HD compound low manual transmission. This p/u had a block heater and on cold days I would leave it plugged in overnight even though it was in an insulated garage because I'm a wuss and like instant heat from the get go. After sitting out in the cold all day at work, no problem with the engine turning over because of using the correct winter weight oil. The gear oil in the MT, transfer case, and differential was another story however, it felt like I was dragging a battleship anchor behind me for the first few miles until it warmed up some, the manual transmission was especially difficult in pulling off crisp shifts.

There is a demonstration of this gear thing in the second ESSO video that is a real eye opener. Start around 1 minute 22 seconds.

First ESSO video at 4 minutes shows a 15W40 product at -35 F. You might find that interesting.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
