Y'all need to stop saying silly things because I will castigate you for it.



Why do you think going to a lower viscosity grade will help you? I assume

you are running a 15W-40 viscosity grade.


Well, I guess someone has to be the scrapegoat for your wrath.

I need to check the oil I put in last year. First change I did in this vehicle. I am very bad on preventative maintenance. I admit it. The other thread that Gimpy started had me thinking that I might be well to change to a lighter viscosity oil. Since I mostly drive this truck in the winter time, maybe 2 hours every time I plow, it doesn’t see a lot of work. Should be able to run the lower viscosity in summer without a problem?

You, Finch and Timmy, do make it easy.

Hmm, might have to go look for that thread or maybe you can post a link to it.
And thank you.

You did not answer my question of why you want to go with a less viscous
oil.

In lubrication, if in doubt, go more viscous, like up one grade. This I think
is where the fallacy that more viscous oils lubricate better. Not true, but
you are less likely to have a catastrophic failure with a more viscous oil
versus a less viscous oil.

Now your engine 6.9L diesel, most likely should be running a 15W-40.

Now lets discuss what xW-y means. The xW part is the cold temperature
performance of the oil. The testing is done below 0°C but the temperature
varies depending on which particular grade you are discussing 0W is the
lowest at -35°C. The '40' is the viscosity measured at KV100 or kinematic
viscosity at 100°C or 212°F the boiling point of water. Generally slightly
higher than a warmed up engine.

So if you want an easier starting engine in the winter but still have good
protection in the summer and when your engine is hot in the winter, you
are better off running a 5W-40 over a 15W-40 (I run 5W-40 in all my diesels)
versus a 10W-30. A 5W will allow an engine to crank over easier in the
winter than a 10W and the 40 will protect the engine (where a SAE 40
grade is recommended) when the engine is at operating temperature.

One of the few electrical questions I know something about. If you are going to use a simple parallel battery setup then you need to use two of the same batteries. If you don't the two batteries will constantly try to equalize the power between the two wearing down the battery life as well as discharging them. Same means the same also. Not different batteries with the same specs. If you want to use the batteries for separate purposes like one for starting and one for the plow they need to be isolated from each other which leads to some easily solved charging issues.

There are plenty of youtube videos covering this.

For what it's worth "weight" was originally a measurement in the refining process to define what crude has been refined into. The measurement was used to differentiate one product from another. The meaning morphed in to oil weight meaning the same as viscosity. The explanation of this came in a class years ago and began with a prof tripping someone up with the same humor you've used.

What you are referring to was the various cuts that were extracted
from the crude oil at the refinery. The cuts were differentiated (and
quality controlled by) specific gravity or more commonly API gravity.
Even back then the term 'weight' was frowned on.

And I am frugal.
For a truck that only runs around your place, I'd go the cheap route; but you
know as well as I do, when you really need it, it will fuck you.

I just swapped out both my batteries in the F-350 back in November, but I
have to rely on it to start in the winter. As long as she is plugged in when
it gets cold, she starts the first time and fires right up. Good batts, 5W-40
Delvac 1 engine oil, and block heater, she starts every time. When it gets
cold, I avoid all biodiesel, and add PowerService 911 to the tank every time
I fill-up. Only one issue in 18 years, I had the fuel gel up on me once and it
was bio-diesel that fucked me. If the truck does not get plugged in, she can
be tough to start but usually can get her running.

Can't disagree with that and this was an aside to the class topic of engines so I had to look this up to find out what I was being taught. When working with bulk volumes for inventory or transportation volume was\is translated to weight. Still seems to be but didn't say why. I can understand the transportation need for weight but inventory? Why not gallons? You are right though that this has little to do with the "oil," and what it is or used for where gravity measurements says it all.

Everything in the chemical business is filled by mass (weight) if you fill by
volume, you also have to fill at a particular temperature. For example, if I
fill a '55' gallon drum cold but put in 55 gallons, depending on the substance
it could over flow on a hot summer day. Expansion is a bitch, everyone of
our products has the thermal expansion coefficient calculated on it then it
is confirmed with the first 3 batches. We fill to the mass that is equal to
53 gallons volume at 60°F. BTW, a standard 55 gallon drum will hold
57.5 US gallons if filled completely. For some strange reason Big Oil is
touchy about spills...

I have seen overfilled drum plump up and leak, not pretty when your
customer calls bitching you out. I have also seen chemicals react with
unlined steel drums and generate hydrogen. Because the fill line didn't
use lined drums. Nothing like a 55 gallon bomb.
