Which one should I go with the 7000 or the 9000?
I live in Washington state where it does not get too cold. West side of the state. coldest is nornally 30's.

How long has the 9000 oil been around?

What is the difference in the oils.

Thanks,

 

JTHarvey is the man to ask about Schaeffers, he's a Rep. He can tell you anything you need to know about it

 

7000 is a conventional and synthetic blend. The 9000 is a full synthetic.

 

I also use the 9000 with great results definatly worth the money

 

i ran the 9000 in my van. Great oil, much better than Mobil1. Local Amish guy sells it and got me on it. I was slowly changing my gas engines over to 9000, Now, with Mobil1 at nearly $8 a quart, I will definitly change my engines to 9000.

I noticed less consumption with Shaeffers 9000, still changed it every 10k with filters at 5k. I think its safe to go 15k with this stuff and I would be willing to try it.

I would like to get some feedback from diesel guys on the schaefers oil.

 

Question,

So what is the difference between Shaeffers and Amsoil??

Don't mean to hijack your thread, but just wondering is all.

Doc.

 

It's like saying what's the difference between Chevy and Ford. Two different manufacturers.

 

Thats what I was thinking, but thought that I would ask...

Doc.

 

Bowie, not sure where in WA your at, but I run 9000.

 

How long is it in the 30's? You'd probably be just fine with the 7000, but the price difference between the two isn't really all that different. You'd be completely safe to run the 9000 all year round as well. That's all I ran for 4-5 years, with lows down into the single digits over the winter and highs in the upper 90's over the summer.

The main difference is honestly just the weight of the oil. They both perform equally well at protecting the engine and providing extended drain intervals. Even though the 7000 is more of a synthetic blend, the "dino" portion of that oil actually can be classified as a synthetic, because of the hydrafinishing process that the base stock is put through. The "dino" portion is actually a better base stock than what most of the other oil brands classify as a "full synthetic" oil.

What you will get with the 9000 though is easier starting and the engine will achieve full lube quicker upon startup, because it's easier to pump than the 7000. That will help reduce wear on the engine during the critical time of startup, when you've got some parts running without any oil for just a little bit, until the oil can be pumped to the top of the engine.

The 9000 has been around for at least 5 years. I don't know for sure when it was released, but I started running it around 2004, IIRC, so it's been around at least that long. It has been updated though to keep current with the newest API specs.

As for actual differences, such as what base stocks and what friction modifiers are used...that's pretty much unknown because Amsoil will not release any data about their oil. Schaeffer's has tech data sheets available on their website (Schaeffer Oil 3.0 | Industrial Lubricants | Diesel Fuel Additive | Synthetic Motor Oils) though, where you can see all the specs and a written detail about the oil.

I called Amsoil, trying to find out specs about it. They told me that information is not available to the public. Even when I told them I needed it to make an educated decision about what oil I was going to purchase, I was given the cold shoulder. My thought is if they're so proud of their oil, why not tell me about it?

What I can tell you is the UOA (Used Oil Analysis) results I've seen were not very favorable for Amsoil at all. Rich (white buffalo here) used Amsoil for a while in his PSD before he switched to Schaeffers, and was actually very disappointed in the Amsoil results. Perhaps he'll chime in.

 

DR JOE asked:


I don't want to spark an oil war here...but look at this info. Mind you, I use neither of these oils...so I have no dog in this.

First Schaeffer's Supreme 9000 has a TBN of 12, while AMSOIL Synthetic 5W-40 Premium Diesel Oil has a TBN of 8. I will bet a UOA on the Supreme 9000 oil has a TBN greater than 8 after 5000 miles (I bet someone here can demonstrate that...please post a UOA showing TBN if you have one)! Now look at this from Schaeffers website:


Notice the words "formulated to meet and exceeds the following manufacturers specifications...". This means that this oil has been tested by the engine manufacturer against their specifications and Supreme 9000 exceeds their specifications.

Next, look at the info I gleaned at the Amsoil site concerning their AMSOIL Synthetic 5W-40 Premium Diesel Oil:


Notice the words: "It is “backwards compatible” with pre-2007 diesel engines and recommended for newer and older diesel and gasoline engines and other applications requiring the following worldwide specifications:"

It does not state that it meets and exceeds ANY requirement, just that it is "recommended". I think this is, IMO, a deceptive practice. It is meant to infer to the user that the oil meets spec's, while in fact it has not been tested. Why, hasn't it I ask? Here is the Delo 400 LE 5-40W specs, for comparison:

Delo 400 LE Synthetic SAE 5W-40 meets or exceeds all major API, ACEA and diesel engine manufacturer's requirements, including:

API Service Categories CJ-4, CI-4 PLUS, CI-4, CH-4, CG-4, SM
ACEA European Service Categories E-7
Caterpillar ECF-3, ECF-2
Cummins CES 20081
Detroit Diesel Corp. Power Guard Oil Specification 93K218, 93K215, 93K214
MB-Approval 228.31
Mack EO-O Premium Plus 07
Volvo VDS-4
Renault RLD-3
MTU Category 1

Notice, it states almost what Schaeffer's states..."meets or exceeds". Remember, Schaeffer's 9000 "meets and exceeds", certainly a higher spec'd oil that Delo 400 LE.

Lastly notice that Schaeffer's Supreme 9000 meets Navistar requirements and Amsoil Premium Diesel Oil does not (of course Amsoil meets no manufacturers requirements). That, for me, is the nail in the coffin for Amsoil (as well as the fact that it has zero moly the last time I knew). If I am wrong in my comparison and analysis, I welcome correction.

 

I live in North Renton (by cougar Mt), so if anyone ever wants to go in on a 350 order for schaeffers then let me know. I am about to order so let me know quick. Should not have a problem with making the 350 number this time though.


In talking with the sales rep in my area he was actually trying to steer me the 7000 version. The rep is just a guy that likes to go with what has got him there in the past he said that the 9000 was relatively new.

But if you guys have been using it no problems then I am fine with it.

Thanks for chiming in all who wrote.

 

I ran the Amsoil DEO 5w40 fully synthetic for 13K miles with a bypass filtration system, and am now running my second cycle of Schaeffer's 9000 5w40 in the same engine (first cycle was for about 13K miles) - my 2002 7.3L PSD in my F250. I have no plans for trying any other oil.

OBSERVATIONS:
1) I reached higher wear metal levels much faster with the Amsoil in comparison to the Schaeffer's 9000. Each time, I ran UOA's at the midpoint and endpoints of the run. For each oil change, I changed BOTH the bypass and full flow filter elements to ensure an apples-to-apples comparison.
2) Engine sound is much smoother, steadier, and slightly lower-toned with the Schaeffer's... the only other way I can say it is that the engine sounds "stronger", almost like it's hunched down and ready for action. I know that those descriptions are rather subjective, but I've also heard similar comments from other Schaeffer users.
3) I can't quote the numbers, but the Scaheffer's has more moly in it, which is about the best friction modifier you can find in an oil.
4) The cost of the Schaeffer's is much less than that of the Amsoil.
5) I know this doesn't really count for anything from a technical performance perspective, but the Schaeffer oil actually SMELLS better than any other motor oil I've ever smelled... does not have the same pungency.
6) Another "doesn't count" observation - the Schaeffer oil has a dark green tint to it.

 

Neal, thanks for posting that. Good info there!

Bowie, there's nothing wrong with the 7000 at all and it works great! I've got some friends here who use it year round without any problems either. A lot of the older reps seem reluctant to switch over to 9000, even if the application (ie colder weather) would show a benefit of it. You know how that goes...their thought about if it's not broke, don't fix it. But, that can also limit them from seeing new and better things.

If you're going to be under 40* overnight for a month or more, I personally would be running the 9000 in the truck.

 

I have gone from delo, rotella, rotella syn, and now the 9000 supreme. My truck loves the 9000 supreme and the price now is better than the rotella. I am with Pete on the smell, with rotella and delo I would loose that "fresh diesel smell" almost right away. I am at 1000miles on my 9000 and I still smell fresh as the day I put it in. My oil hasn't turned black yet either, on the other brands black oil was right away. My ccv smell is not noticable now either where as before it was pretty bad. I am a big fan of Schaeffer's.
