Deleted Non LE Oil???

[Cummins12V98]

Ok you deleted experts. My Son did a complete delete on his 15 3500 SRW Limited. Since all the emissions stuff ran away I would assume it's no longer required to use LE oil. AMZ/OIL still sells their 15-40 Diesel Marine, I "assume" it would be fine for him to start running this now???

He went with Sinister Diesel.

Yes he can run a CI oil in his '15 now. Amsoil's AME is the CI oil I would run if he wants to go that route.

That being said DME, CK, is a better oil even thou it's for LE enignes. It has a better wear package, and better high temp stability/viscosity. I has switched my 05 over to DME before selling it. It ran slightly higher pressure for the same temps, and it also seemed to run a little cooler as well. (aftermarket oil psi and oil temp gauges).

Ron,
I did the same thing on my 09 4500 in 09. I ran basic Amsoil 15W-40 for 9 years with superior results. The last year I put everything back on and still had superior results.

I guess Marine Amsoil better than thier basic stuff, when the basic oil is so good. No oil wars within the Amsoil ranks, please.

Cheers, Ron

Better and i think a bit more expensive.

You know, I'm a type A and tend to over study things a bit. I guess this is one of those cases where 99.8 is near enough to 99.9 to call it good. caveat: I made up the numbers to make a point, see I'm honest. I've been to the Amsoil website and compared offerings. When all is said and done, there is still a market for the basic package, especially if following mileage oil change interval.

I'm not sure how long my brethren have used Amsoil, but I've been a user since 2000. The basic stuff got me through three Ram Cummins trucks, all heavy towing with amazing results on oil analysis. Do y'all have oil analysis with basic and marine that demonstrates superiority? Not being arguementative, but I can't think of any other way on our trucks to quantify "better."

Thanks for the forthcoming education.

Cheers, Ron

Friends,
Just for grins, went to Amsoil website, plugged in my vehicle info (5500) and this is what is recommended by them:

Pretty interesting, huh?

I don't see a marine 15w 40. Closest is a 10w 40 in the marine offerings on the amsoil website.

Here is what I use

Not surprised, the Ram all weather recommendation is 5w-40.

If anyone ever ventured off this website and actually went to a dedicated oil website they would learn the boutique oils are pretty much a waste of money except maybe if you cold start in -30*F every day.
But I digress....

 

[Cummins12V98]

The 15-40 Diesel Marine is still sold. I just bought some for my 01 Sport.

My Dad is the first AMZ/OIL Dealer in WA State. So I have been using it since early 70’s.

So thanks for the info guys. My Son is an AMZ/OIL dealer on the east side of DFW, TX.

Bob is the oil guy?

 

[Cummins12V98]

Oh another thing I spell it the way it originally was spelled. “AMZ/OIL”

If you want swad information about amsoil you go to amsoil website. If you swad information about Mobil you go to mobils website. If you want swad information about (insert oil company) you go to their website.

If you want unbiased information you go to www.bobistheoilguy.com

Cold and hot is where they have benefits, thou modern CK oils all seem to do better at high temps than previous specifications.

When I rebuilt my 05's motor I ran Delo for about 10K miles and even when warm the Delo would take longer to build oil pressure (psi gauge in the cam journal on the drivers side of the block). When it got below 25°F the Delo acted more like a 40wt than a 15w-40, relative to Amsoil AME. In the freezer at ±0° Delo was MUCH thicker, and I sure wouldn't have wanted to get to -10°F with it in the block.

They also have some benefits of lasting longer between oil changes.

I also like keeping a 15w-40 in the motor vs a 5w-40. There are some benefits with NOACK volatility and high temp/high sheer sticking with the 15w-40, and a full synthetic 15w-40 has great cold weather properties.

At the end of the day it all depends on how you use the rig, and what you're willing to pay for. Aside from the hot/cold performance I like longer OCI's on my rigs.

bobistheoilguy is a great site, and I've spent a bit of time researching stuff there too.

This. /\ See above quote.

Just this alone is why i have spent more on "boutique" oils. If Delo, Shell, Valvoline, Kendall, Mobile and others made a 15w 40 or 20w 50 full synthetic, i probably wouldn't spend the extra money on Amsoil or Redline.

I have had some isolated issues with fuel dilution using it as a daily driver. This month, i have travelled 3500 miles from Florida to Oregon and don't observe a significant increase in oil volume in my sump. I was looking for a local lab to do a quick oil analysis, but the closest one is a 2 hour drive from Eugene Oregon. I don't want to drive 2 hours (4 hours round trip) just for a UOA.

I probably (right now) have at most 1%-3% fuel dilutuon even on a cross country trip. Using it as a daily driver i have (the past 2 years) experienced 6%-8% fuel dilution (confirmed by UOA) probably due to excessive active regens. (I suspect active regens as the cause because it is periodic dilution, not constant dilution). If i had a leaky fuel injector, the fuel dilution would not be periodic...., it would be constant. 1-3% fuel dilution is not going to dilute my 20w 50 oil enough to reduce film strength and high quality additive package to a concerning level.

My oil experience:
I change it a 6 month intervals.
I use 5W-40 T6 all year.
In combination with the oil pump and internal resistance to flow, it has oil pressure
It is slippery
It is oily
Engine has not grenaded
Never give it a second thought.

T6 is obviously the best oil.


Almost forgot.....most importantly, I go through the fender.

Looks like its a few bucks a gallon cheaper than Amsoil DME, and likely easier to obtain.

Does Rotella offer extended drain intervals with it?

It is a bit thinner than the Amsoil DME at 100°C. One of the reasons I switched to DME from AME was to get a thicker oil at 100°C.
