Mobil Delvac 1 Oil

[Mr Freeze]

Diver Dave

If I could not get AMSOIL, I would use Mobil Delvac 1, it is a super product and in it's current form will meet every spec that your truck requires. Sleep easy and use it. I've been a AMSOIL dealer since 1981, and I am still amazed at how uninformed some service people are. Keep on synning!

Diver Dave,

Just got another oil analysis result from Blackstone Labs--I did one to make sure there was no fuel dilution after installing injectors. . .

Oil: Mobil Delvac 1 with CG-4 rating
Miles on Oil: 5,200
Filter changed: 1
Makeup oil: 1. 2 quarts
Driving conditions: over 50% short trip, cold engine operation (start up, drive 2-5 miles, shut off several hours, repeat, etc. ) Only 2 "road trips" totaling 1200 miles.

Results:

Iron--13ppm
Aluminum--2ppm
Copper--1ppm
Tin--0ppm
Silicon--8ppm

SUS Visc@210F--72. 1
Flashpoint--430F
Fuel-- <0. 5%
Water--0. 0%
Antifreeze--0. 0%
Insolubles (soot, etc. )--0. 6%

When I talked to Blackstone, they asked if I changed the oil. I told him "no" and he said "good, your oil is still very good. " The only parameter which seems to be headed "out of range" is the soot value, but I'd say there's an easy 10,000 miles of great protection even with my "severe use" type of driving. I think the very low metal counts with regular filtration can be credited to this oil. 7500 miles is too soon to drop the oil IMO #ad

I aggree Mr. freeze,why waste your time with delevac1 when the amsoil is a little cheaper and has been in the automotive synthetic industry the longest.

No high tech fuel system needed. Just good old fashioned diesel power!!

 

[nutter3]

Can anyone give me a number or link to someplace that does oil analysis? Where is this Blackstone that Vaughn is using? And also how exactly do you get a little sample bottle full of oil without making a huge mess? Do you take the sample from the filter? Thanks for any information.

FL60CUMMINS:

The reason for my decision to go with the Delvac 1 oil was because of the 5W40 designation rather than the 5W30 of the Amsoil product. I wanted the Higher Viscosity rating. I wanted it Thin in the cold, but Thick in the heat... If you know what I mean. By the way if you buy right you can get it down to less then $4 bucks a quart with tax included.

Also the Delvac 1 oil I bought now has the CH-4 rating (Better soot control is my understanding).

And if we all bought Amsoil how would ExxonMobil ever make any money... . HEHEHEHEHE.

Don't want to get personal, but I will bet you are a "Amsoil Dealer". Well here goes:

Using your argument that Amsoil test and Mobil does not. Look at the chart below "supplied by Amsoil". Since I am using this oil a Cummins engine and not a race car (20W50 is more for that use as I understand it) lets use the figures for Diesel oil, in this case Amsoil 5w30 and Molil Delvac 1 5w40.

#ad


Now in this Amsoil test the difference is only . 04 of a mm diamiter or about 10% not the 300% you mention in your post. If you further understand that Cummins recommends a 10W40 weight oil (the big number is important here). I would rather have the 5W40 oil in my truck, which will protect over a much wider temperature range.

I'm not an expert, but I did research this oil thing in some depth before I made my choise.

I am one that likes to see data to make my informed choice.

Amsoil always gives the most data on the performance of their products. And they also test their products against others and use independant labs to do so. Why do they do this??? Because they are confident of their products.

I have yet to see as detailed data on Mobil 1 Delvac as Amsoil. One piece of data that is important to me as an indicator of the oil's ability to reduce wear is the Four Ball Wear Test.

There is other data that Mobil 1 chooses to talk alot of talk, but doesn't show numbers.

I am not trying to bash any one's oil selection, I too want to use the best for my baby. But until I have data that will allow me to compare apples to apples, I will stay with the company that puts up, and makes others shut up.

One of the direct comparisons that I alluded to is the testing that was done on Amsoil's 20w-50 series 2000, and compared against Mobil one 15w-50, redline 20w-50 and others. Now I am not using this as a direct comparison for Delvac and Amsoil as that would not be apples to apples. But product to product, Amsoil 20w-50 series 2000 racing oil against Mobil 1 15w-50, side by side test, Amsoil 4 ball wear was . 514 scar
Mobile 1 4 ball wear was 1. 474 scar
Almost 3 times the wear.

Something to think about.

Cheers

DiverDave,

Yes, a dealer, but only to get the wholesale price not to sell.

I was not aware of the test you list, I was quoting from the testing using the gas engine 20W-50 oil, hence my saying I was not comparing apples to apples, in that test the difference was 300%.

Cummins recommends a 15w-40 oil for the warmer temps, not the 10w-40 you mention. I personally will not use Amsoils 5w-30 in my truck unless the temps are real low. One reason is because that is what Cummins recommends, and secondly, if all other issues are the same, a thicker oil has greater shear stability, and wear protection than a thinner oil.

Also the prevailing information out in the lubrication world is to avoid having the first number 10w or 5w be separated too far from the second number 30 or 40. This is due to working the viscosity improvers too hard. Since synthetics don't have to use as many V. I. 's as petroleum oil, it may not be as big of a deal, but something to think about.

And finally, Amsoil 15w-40 oil has a four ball wear rating of . 35, further out doing Delvac.

Sounds like you like to make informed choices like me. So check it out. Delvac is a very good oil, but Amsoil costs less and out performs Delvac. Sounds like an easy choice to me.

Cheers

All,

New member to TDR and Dodge/Cummins TD with some observations and a question regarding synthetic oil application and Delvac 1 5W-40 in particular. Not sure where to post this since the oil threads appear in this and the Product forums:

Question:
I have noticed in numerous posts that many of you use the Delvac 1 5W-40 synthetic only in the winter, opting to change back to conventional 15W-40 in the summer. I understand the desire to derive the cold weather benefit of synthetics, but, other than cost, why would you want to divest yourself of the synthetic oil properties during the summer? Is this just a personal preference or is there some technical reason that makes you believe Delvac 1 5W-40 is not suitable for summer use?

Observations:
Having monitored numerous topics in this forum, I am appreciative of all the technical information and experiences unselfishly shared by its participants.

Regards.

Is AMSOIL kinda like AMWAY?

 

[DocStressor]

CatHerder - I like your handle. As chairman of an academic department, they say that my job is supposed to be like herding cats. There is no significant technical reason not to use lower viscosity synthetic oil. Engine manufactures recommend viscosities based on the properties of conventional oils, which are used in the great majority of engines. For uniformity, oil viscosity is measured at 0 degrees Celsius (32 degrees F) and at 100 degrees Celsius (212 degrees F). The viscosity measured at the lower temp is the “W” value and that measured at the higher temperature is the other number. So 15W-40 oil has a viscosity of 15 weight oil at 32 degrees and the viscosity of 40 weight oil at 212 degrees. Viscosity of a solution is generally determined by the longest molecules present in a mixture. Conventional multi-weigh oils are produced by adding a small amount of a polymer that increases in length when heated thus stabilizing the viscosity of the lighter oil at the higher temperature. Unlike conventional, synthetic oils are composed of a molecules that are very uniform in size and many do not even need a viscosity improver to have multi-viscosity properties. To address your question, you have to realize that in a working engine, oil temperatures exceed 212 degrees. Thus, it is the viscosity of the lubricant at operating temperature that is important for protection after warm up. Because of their chemical properties, synthetic lubricants rated at 30 weight at 212 degrees can actually have a higher viscosity at 230 degrees that a conventional 40 weight oil. Also, because most of the lubricant molecules are very similar in size, it generally takes much longer for a synthetic oil to shear to a lower viscosity. That, plus intrinsic resistance to oxidation and the use of expensive additive packages, is why synthetics can be run much longer than most conventional oils. So in the absence of data from a manufacturer demonstrating problems with the use of lower viscosity synthetics, I wouldn’t worry about using 5W-30 Amsoil or 5W-40 Delvac 1 during warm weather. The lower “W” viscosity has the advantage of providing rapid lubrication during cold starts, even in the summer.

Lee,

Thanks for the technical insight. Been using sythetics for years in gasoline engines. Was curious if TD's had special lubrication requirements (other than CH-4 specs) to be comprehended. Not yet close to making the switch (only 2500 miles), but never hurts to be armed with information

Being a software developer, instructor, consultant and project manager for a number of years, my job is also much akin to herding cats.

I'm don't claim to be an oil expert here, but if your observation is correct then I'm going against the majority - I feel the use of the synthetic is even more important in the summer than in the winter. My logic goes like this: With EITHER regular or synthetic oils, the Cummin's engine will probably still be the longest-lasting component in the truck. But the turbo concerns me, especially for relatively hotter shutdowns in the summer. Add to this that someone else may drive my truck (not very often!), and will probably shut down without a cooldown no matter how much I tell them not to, and having a synthetic gives me a lot more peace of mind. One thing I won't do any more is use the M1 0W-30, even in a gasser. (Never considered anything but Delvac 1 or Amsoil 5W-30 for my Cummins. ) One summer with the 0W-30 product, I watched my oil pressure drop to near the red zone every time I climbed a hill in my Suburban.
I think either Delvac 1 OR the Amsoil 5W-30 would be superior products year-round.

I'm going to use either delvac or Amsoil at my next change. I live in the Philadelphia area. The nearest mobil truck stop is in Jersey and they want 27/gallon. Please help me with suggestions.

If you want to use the Delvac 1, check the Yellow pages under "oil marketers" and you should be able to find someone who can order Delvac 1 that is closer to home.

Yes it is a pyramid scheme. That is one of the reasons that I will no longer do business with them.

Try Mauger Oil in Frazer. 610-644-4000. There on the South side of 30 between 29 and 352. Also Amsoil has a warehouse out near where 340 and 30 meet on the east side of lancaster. Would save you shipping.

Also that truck stop in NJ don't carry Delvac 1 (even though Mobile says they do)

Everyone is entitled to an opinion, some opinions just happen to be wrong.

There is big difference between an illegal "pyramid scheme" and a network marketing system.

If you want to make money with Amsoil, you have to sell product. Pretty simple and honest, isn't it?

If a Mobil salesman signs up 100 auto parts stores, he gets payed for what they sell. And his district manager gets paid for what ALL his salesman sell. And the zone manager gets paid for what all his districts sell. And so on, right up to to the Mobil CEO.

Same with Amsoil.
For some reason, it is ok for Mobil to make money and pay huge bonuses to corporate big wheels, but if I get a $100 bonus because my customers use and my Dealers sell a lot of oil, it is a "scheme"

These myths are getting old, and double standards suck.

I agree with Gene. Amsoil will sell anyone a dealer's license and never pressure that person again to meet a sales quota. I have a license that I pay 20 bucks a year for just so I can get the stuff wholesale. That's the only reason I'm a dealer. Double standards do suck, but that's life I guess. I just went to Amsoil 15W40 synthetic. I to am using the "cheap" Fleetguard Stratapore filters. I plan on changing filter and adding makeup oil every 4K miles and doing an oil analysis until a pattern can be established. I will post those results when I get them. Let's see if we can get some definitive results, regardless of brand favorites.
