Deleted Non LE Oil???

In the 1970's we use to cold start with 15w40 conventional that was total junk oil compared to today's oil. Engines still lasted as long as our southern neighbors.

In the United States the company Mobil process invented synthetic oil during World War two. Germany, USA, both invented the technology for synthetic oil processing. Amsoil is just one of a few spin offs.

Engines, bearings, & tolerances in general back then were built sort of with sloppy spaces and loose tolerances. Today's engines require a different lubricant than back in the 70's. Not fair to compare 20th century manufacturing with 21st century manufacturing.

I was comparing the junk oil and engine longevity vs today's oil and longevity. The technology in today's engines drives the technology in oil. Conventional oil is superior today vs 1970's oil. If today's conventional oil was still 1970's standard I would be singing synthetic oil praising along with you guys but it's not. Better refining and superior additive packages brings conventional oil so close to synthetic that some are actually called synthetic. LOL

They are certainly closer, but not as close as you want us to think.

When you can hear and see a difference on cold starts and hot runs then they are not that close.

I wouldn’t mind running cheaper oil if it was the same, but it’s not. I’ve stopped running fuel additives every tank since there isn’t an appreciable difference to me, but the oil is still different.

I have not completely stopped the fuel additives because the fuel lubricates and cools the fuel pumps. I use them sparingly, but continue to do so for lubrication. I never used the Amsoil fuel additives, tho. They are a synthetic oil company, not a fuel system specialist

That's not really a fair statement either, conventional and synthetic oils are not as far apart as you want us to believe. In fact a conventional group three oil is a synthetic.

Since 1999 I've owned 6 Cummins Rams and 1 Hemi Ram and 1 Ecodiesel Ram. Never have heard any difference running boutique Synthetic, group three Synthetic, or Conventional oil and at times my vehicles can sit for 2 weeks or longer until startup.

I don't know how you see a difference in startup.

The only difference in hot runs that I know of is oil pressure and oil pressure is not always a determining factor of sufficient lubrication. If you can tell a big enough difference in heat your engine has bigger problems than what oil you run. I personally have never seen the drop in engine or oil temperature claimed by synthetic oils.

At the end of an engines life you might be able to see some spec differences but the engines are dead so what does it matter or you have already sold the vehicle so what difference does it matter. It's never been proven a synthetic oil run engine lasts longer then a conventional oil run engine. I point out my experiences come from a region where temperatures range from +100*F to -40*F. In 60 years I've used a lot of different oil and experimented with a lot of oils in farm tractors, highway tractors, trucks, pickup trucks, cars, Motorcycles, high performance cars, diesel engines, gas engines, 2 years gas engine tech school, and a host of street/barnyard engine tare downs and swaps. I speak not from factory propaganda but from life experience.

With all that said there is a place for boutique synthetic oils just not so much needed in conventional engines. If you want to run boutique synthetic oil it's certainly not going to hurt anything but your wallet.

Fake news?

With a non-OEM oil pressure gauge

I had it in the cam journal, which is far enough from the oil pump that you can see a very noticeable difference. The same difference you can hear.

 

[Newsa]

oil pressure is not always a determining factor of sufficient lubrication. .

Yeah, true especially if you are pumping substandard oil. But i like to have both.....Quality oil and pumping at good pressure.

Granted. CK conventional oil is much improved over CJ conventional.

Not trying to convince anyone. Just contributing to the conversation. I'm happy with my light wallet.

Fake news?

Do you know who paid for the testing?
Or contributors to the testing?

Was the survey done at only AAA's recommended repair facilities?
Or customers of AAA's, or customers of AAA's recommended repair facilities?

Where did I ever say conventional oil was better than synthetic oil?

I can guarantee to 99.999% that the synthetic testing was on group 3 non boutique synthetic oil. Add in the cost for YOUR boutique synthetic the price just got higher, add in the cost of membership fee for YOUR boutique synthetic oil the price just got higher, add in over double the oil used in your Cummins Ram the price just got higher.

Without rereading this whole thread it seems to me the only synthetic contributors to this thread are Amsoil customers or a dealer on Amsoils legal pyramid scheme. Heck even the thread starter @Cummin12V98 is a Amsoil user and pretty sure a salesman for Amsoil. Isn't it against forum policy to solicit sales other than vendor forum. Another way of amsoil skirting policy by asking a question thereby creating a discussion to solicit customers. @Cummins12V98 should know the answers to his questions if he is!

LOL, fair enough, LOL
In the right conditions Lower oil pressure and noise is not any indication of wear. If it was every Harley Davidson I know would have crapped out useing synthetic oil, for those who don't know just about every Harley Davidson runs noticable louder cold and hot on Synthetic oil.

What do you mean by substandard oil? Is the Cummins engine platform not built around conventional oil?

Do you need champagne to get drunk when beer will do the same for less cost?

 

[dieselshadow]

I run all of my HDs on synthetic oil, period. Air cooled engines respond very well to synthetic oil. You can definitely feel and hear a difference. If you pay attention to the inside of the engine and what’s drained out, you can see the obvious difference as well. They look new. Modern conventional oils are pretty good as well, but they still don’t match full synthetic.

Oils are very much a personal choice anymore. You say this is your favorite and 300 people will tell why it’s the worst oil ever. It’s like Chevy vs Ford and who has the best tire. Do the research and figure it out for yourself. Stick to what you choose and run with it. When was the last time you heard of a failure due to oil? I haven’t in many many years other than flat out abuse and lack of any maintenance.

I probably won’t run full synthetic in my Cummins due to the ridiculous 6 month maximum time rule. If it was an annual minimum, than I’d probably go full synthetic. Again, personal choice.

Your mileage may vary.

The oil i sent in for oil analysis was kendall super d xa. It is a good oil, but after 4000 miles was laden with 8% fuel dilution. My truck was entering regen often enough to dilute the crankcase oil with diesel.

Other examples would be oil overloaded with soot.

I just drove 4000 miles on the hwy the past month and not seeing excessive fuel.dilution of the oil. Using 20w 50 instead of 15w 40 just in case

My point exactly, let me explain.
Nope no one has heard of an engine failure due to oil, without extreme abuse or lack of maintenance. Yet if an oil protected to 100% then an engine should live indefinitely barring electrical or fuel system problems, right. So why does an engine deteriorate, non sufficient oil lubrication. Engines run on synthetic oil last no longer then engines run on conventional, period. Never proven in an unbiased laboratory. I can guarantee the inside of the engine will look different and even spec different but the conventional oil engine will live just as long proven by million + mile engines run on conventional oil. Yes, there are million mile engines on synthetic too. Just trying to show a point.

Not trying to persuade anyone to any type or brand of oil, just contributing to the conversation.

Too funny! I don’t have an AMZ/OIL account. I DON’T sell AMZ/OIL.

I HAVE USED AMZ/OIL since around 1973.

My Dad is the first AMZ/OIL Dealer in WA.

My Son is a AMZ/OIL Dealer in DFW, TX.

Are we clear now???

But that doesn't mean the oil was substandard. It means you have other problems contributing to fuel dilution.

Definitely clear! Pretty loyal, I have to at least admire that.

Who do you buy amsoil from?

Why start a thread asking a question on a subject your amsoil selling family would/should know? I'm sure you just wanted others opinion!

I said a salesman, not dealer. My statement still stands.
