Diesel oil

[PoginyHill]

I don't remember where I read it, but the synthetic 40 weight oils were supposed to be match 40 straight weight. I think maybe because synthetic inherently has better flow characteristics, it doesn't need to have additives to improve cold performance like a conventional 15w40 would. So it stands up like a straight 40 at working temps. Anyways, that was my understanding, I wish I could remember where I saw it. Also, CK oils are low ash for emissions reasons. And lastly, I might be a bit jaded towards my Detroit because I wouldn't care if it grenades so I could do a Cummins swap😁

In the video I posted earlier in this thread, it was explained that any straight weight oil will be thinner at higher temps and thicker at lower temps. The multi-weights level out that so it has nearly the same viscosity no matter what the temp. For brand new oil, conventional and synthetics perform identically. Over time, however, conventional oils will tend to thicken (at all temps), where synthetics will remain similar to new as far as the viscosity is concerned.
What you might be recalling is that synthetics are developed from "scratch" with these properties. Conventional oil requires additives to make them behave a certain way. And it is those additives that degrade over time.

I have used Amsoil synthetics in every thing for years. 5W 40 is fine year round in northern climates.
15 40 in warmer area although it will work in the cold too. the 5ws are as much about fuel economy then starting. Most engine wear is at start up and synthetic oils prevent that. Pony start cats lasted forever because they were warmed up and had oil pressure before they started.

all their additives greases and 2 stroke oil are top notch too..

I change my oil once a year. If you pay a yearly fee they give you a discount and ship free.
Costs more up front but saves in the long run. 

You can also save money by using oil analysis. many large fleets run the oil to 100,000 miles with analysis and filter changes.

I think Amsoil has some good products, but I don't care for their marketing. Or their diesel synthetic oils being twice the cost of Rotella synthetic. It ain't twice as good. 

Dgrls, it's a 3-53. There's a lot to like about them- good power, easy on fuel, starts decent.  But every time I run it for more than an hour, I start hating the noise and the dirt bike power delivery😊

I remember when 53 series where called Yamaha's. Back in the day Yamaha had sold a lot of small 2 stroke bikes, road bikes, if memory serves they where twins and you could hear them a long ways off.

[barbender]

I remember those bikes! My buddy had one, a Yamaha RD 350. Two stroke twin, piped. That thing was a rocket! And yes, you could hear it from about the same distance away as a Detroit (8-10 miles)😂

 The concept behind a 2 stroke is so awesome when you can see it end to end, on something like a 645-710 EMD. We would probably be speaking German right now if it wasn't for Grey marine / GM 2 strokes during the war. Alot of the noise is because the cam and valve train is going 1/1 unlike a 4 stroke that's 1/2 the speed. When I make money like Ed I'm going to find a 1-71 for my living room. Maybe a 51 series 🤔 

 My mechanic wants to try this stuff 🤷‍♂️ I've got to fill those bulk tanks in my shop now. 


 
  Priced it bulk delivered thru our salesman, I don't think I'm gaining much just on the convenience.

All I know is I don't like the noise they make, Barge. I don't care where it co.es from😂 The main problem on my ol' Pettibone skidder is the exhaust exit is about a foot behind and above your head on top of the cab. Gosh that thing is nasty!

[mike_belben]

same with my forklift.  the truth is a detroit doesnt make any noise at all, like trees falling in the woods when no one is there.  

the sound youre hearing is the metal trying to hold a detroit inside it, reaching its 3rd order harmonic frequency and resonating like a hive of metallic killer bees.  


far as oils its money in the bank to buy as much as you can when you got the spare coin.  it dont go bad, it only gets more expensive and if youre using it youve either got a critical need or are making money consuming it.  on the very rare occasion i have a chunk of cash i go fill the shed with pails and dont think twice.  when im down and out, its wonderful to walk in the shed and find hey.. ive actually got one more pail of machine sauce. i can make it to tomorrow again without a dime. phew.

Company I work for uses chevron 1540 in everything big trucks and forestry equiptment etc.

I've always used mobile delvac 1540 in my pickup but I'm doing oil changes out of the bulk tanks at the shop from now on.

I was topping my pickup off the other morning it was about 6 degrees and that delvac was pouring like caramel onto ice cream. Not good.

Mike I think you'll appreciate this quick story:
Ten years ago our neighbor unfortunately passed away, but fortunately had his parents offer us the landlocked piece of land that he was on.
Along with everything on it. A shed stocked with a lot. It's like our own hardware/parts store. Oil galore. Just changed oil in the Fordson Major Diesel that came with the land with "free oil".
 Unfortunately his stores of pasta and rice didn't keep.
Also someone stole a lot of batteries and solar equipment as well as a '75 Chevy 1 ton dump and beautiful stone walls.

[mike_belben]

thats a gem.  im real scared of the day they steal the rice and pasta too!

I was a diesel mech for many years and have seen up close the real effects of engine oil.  There are some really good synthetics out there but overall when all is considered, I went to Rotella 15-40 on all my own stuff many years ago.  I use it everything, and I do mean everything.  The availability recently has become a concern, but as long as I can get it, I will use nothing else.  Tearing down motors that have run for years in tough conditions will open your eyes.

[mike_belben]

i used to flip hondas. well, i did a little of everything you can do with hondas.   half the time they were 300K miles on just added oil as rented mules typically go.  the rocker box would be coffee brown.  a few cycles of rotella 15-40 would clear that up a lot. impressive detergents in there. 

[Bruno of NH]

Can't find any Rottela t6 anyplace in my area .

[newoodguy78]

Napa laughed at me when I asked for Rotella the other day. None to be had. 

[snowstorm]

Irving has plenty of 15 40. Talked to the sales rep last week. Every bit as good or better than rotellar I have been using it for 35 years. Only shortage is in the 250 gal. Tote can't get the totes and def

[chevytaHOE5674]

Never seen, heard, smelled, or even heard mention of Irving except by you folks from Maine on this forum. Definitely a regional thing.

On the stone walls, I would turn the other way at my place. 
Now that truck would get someone the buck shot treatment!!!

I've seen Irving lumber in the local Home Depot. Never would've noticed it if it hadn't been for Swampdonkey extolling the virtues of the Irvings on here😁

[snowstorm]

irving is the largest refinery in canada the big one in stjohn nb one in nefoundland and one in ireland. if you buy gas diesel or heating oil in the northeast it came from them. around here it comes into searsport by boat south of here portland or Portsmouth nh. i buy motor oil ect direct from them cutting out the middle man 

[mike_belben]

so who is filling the big tanks in boston and then piping it to gasoline alley in springfield.. is that irving product also?
