Le Dci+

[ROADWARRIOR]

Do you guys know if the LE DCI+ lubricates the VP44 as well as the Lucas upper cylinder additive? Can the two be run together with out any harm? Also, does the LE DCI+ work as a stand alone anti gelling treatment? I just want to get the most lube possible to the VP44, and the Lucas looks like it would lube a whole lot more.



Thanks, Dan

Never heard of the lucas product before. I tried a bottle of DCI+ once. Did not notice any real difference over the stanadyne that I was using.



LE DCI+, Stanadyne, Howes, and Power Service seem to be the 4 brands the masses round here use. Personally I have tried 3 of these 4. I did not notice any real difference. I believe they all work. So I now go for whats readily available at the local stores for best price. Power Service. Every tank.

I tried about a half a dozen bottles of the LE DCI+. Saw no difference of the Power Service. Went back to PS, cheap and readily available. The empty LE DCI+ bottles do come in handy to refill with the amount I usually need to fuel up. A quick dump and start pumping.

Lucas

Being new to diesels when I bought my '95 last year I asked a couple of lumber companies around here who run semis and they all use Lucas and buy it by the 55 gal drum. That was good enough for me and so I started using it. Haven't tried any other such product and am happy with Lucas. I also will dump PS anti-gel in when it gets in the single digits. Ken

Roadwarrior,



Here is some information that might help you. I've copied it from another post that a guy named brian asked some of the same questions.



The lubricity was tested on the BOCLE data test. This test shows the scuffing load, grams of untreated fuel from 5 different locations the untreated fuel ranged from 3000 to 3800 the higher the number shows better lubricity of the fuel. These fuels treated with the LE DCI+ showed from 4100 to 4600. This proves that the DCI+ improved the lubricity of the diesel fuel that you buy at the pump. The higher the BOCLE load the better the lubricity of the fuel. LE DCI+ increased the scuffing load by 19. 4% to 36. 6% over the untreated fuel at the pump. This means that it will protect the pump better.

"7. Combustion improver- makes fuel more volatile for easier starts and more efficient combustion. This makes for smoother running engines and less soot because of more complete combustion means that you will get less soot in your engine oil.

8. Improved fuel mileage by an average of 7. 4% in a five fleet 113 truck test. If your trucks injectors are in perfect condition you will not see this much improvement.

9. Improves the lubricity to protect pumps and injectors,

10. Reduces emissions by promoting complete combustion of fuel- and keeping engine tuned much longer. "



I hope this info helps you

Roadwarrior,

Here is some more info on the DCI+;The benefits of using the LE DCI+ are



1. Ashless detergent/dispersant- this will clean the fuel system from the filters to combustion chamber

2. Oxidation inhibitor- guarantees longer fuel storage life without sludge and gun formation, which will block filters and form choking deposits in the fuel system.

3. Pour point depressant- provides better low temperature fuel flowability for previously untreated or partially treated fuels. This reduces the cold filter plugging tendency.

4. Demulsifier- this helps the water separate in the filter for complete removal.

5. Rust, corrosion and oxidation inhibitors- add years to storage tank life, and other metal components.

6. Metal deactivator- prevents degradation of fuel caused by reaction of copper and bronze and eliminates performance problems in the engine.

7. Combustion improver- makes fuel more volatile for easier starts and more efficient combustion. This makes for smoother running engines and less soot because of more complete combustion means that you will get less soot in your engine oil.

8. Improved fuel mileage by an average of 7. 4% in a five fleet 113 truck test.

9. Improves the lubricity to protect pumps and injectors,

10. Reduces emissions by promoting complete combustion of fuel- and keeping engine tuned much longer.

11. The cost of the DCI+ is about $7. 00 per pint bottle. One pint bottle treats 125 gallons of fuel. This works out to about 0. 056 per gallon of fuel.



In small quantities you can get it from Mag-Hytec at 1-818-786-8325 or e-mail me for larger quantities.



Sincerely, Kevin

FWIW - After having used Howes MPC, Stanadyne, and the DCI +, I prefer the DCI+.



I don't know about the Lucas. The thing that concerns me about it is, isn't it the same additive they sell for a gasser? This doesn't seem right to me. Maybe there is no direct correlation between it's performance and it's ability to treat diesel and gasoline, but it makes me wonder?



My $. 02,

I'm new to diesels and I bought the Rotella DCA fuel treatment. It says that it does the same things the PS does and all of the others. One of the reasons I bought it is that I got it at Sam's Club for $33. 00 for 4 - 96oz bottles and Rotella had a $8. 00 refund coupon on its web site. So I got it for $25. 00, real good price. I also figured that since it was Rotella and I use Rotella T in the Cummins and Rotella is made by Shell, it was a good product. With these types of products, unless you are a chemical/mechanical engineer with all of the test data then all of the comments from users is speculation. I felt that doing something was better than doing nothing and using a major oil companies product was safer than using one by a speciality company that spends all of its development dollars on marketing. Just trying to use logic, my 2 cents

Kevin, I've been using the DCI+ for two yrs then I won a case of Stan. PF last summer. I took a long trip and used DCI+ for one half and the PF the other half of the trip. Using mpg, starting and performance for indicators - I liked both. DCI+ has a combustion improver and PF has a cetane improver. I asked the LE boys in Texas about mixing the two, thinking the catalyst in the DCI+ would compliment the cetane booster in the PF. They said to try it, so I did. I haven't taken any long trips to make a good comparison but it seems to work darn good around town for performance and less smoke! Have you ever tried something like that? Craig

 

[Power Wagon]

Stanadyne PF outperforms all popular other additives in pour point depressant, lubrication, and cetane improvement.



In wear tests, PF decreases wear by 50% over untreated fuel. It is better than even "lubricant only" additives. It also decreases smoke, cleans injectors, protects hard parts from water, demulsifies water.



It is the only additive I will ever use. There are no "equivalents"

 

[Oil Man]

Powerwagon,

Where did you see that it "In wear tests, PF decreases wear by 50% over untreated fuel" as you say. I'd like to see the test results. That sounds like a whole lot less wear. Your statement "better than even lubricant only additives" sounds like hype. I'm just thinking that a lubricant only additive is made to do only one thing and it should do it very well.



Powerwagon, I've listened to you for quite sometime and some good comments you've had. But this sounds to good to be true and you know what they say about that.



I just have to see the test data that supports your statements. If you have it and don't want to post it then just email it to me at -- email address removed --



Thanks,

Kevin

Oil Man-



Please post a link to the complete test results/data/info regarding the results that you posted above. It will be very interesting to see what concentrations were used during those tests. I have seen other fuel supplement tests that used concentrations about twice the recommended concentrations. That way it looks like the product is the "best" at everything but "cheap" to use. If we run the concentrations used during the tests (in order to get the same results), it turns out to be very expensive to use (especially when they talk about fuel savings covering the cost of the product).



Please post the info publicly. It appears that you are a vendor for this product. Is that the case? I believe you are supposed to have that info in your signature.



Thanks,



Dave.

I believe Kevin WORKS for LE as some type of certified lubrication expert, but he is not a vendor and does not make any personal profit from any individual sales of the product. I also know from past posts and e-mails that although he believes strongly in most of the LE products, I have also seen him recommend other companies' products for specific applications where he believes the competitive product had an edge. In other words, he gives you his honest opinion.

 

[Oil Man]

Dave,

I've worked for Lubrication Engineers for 23 years and I must tell you that LE always gives very conservative results to their test data. There is no link to the testing that you asked for. I have inneroffice memos that give that info. The tests done with the LE DCI+ were done at the recommended treatment levels. One pint of DCI+ is used for 125 gallons of fuel. Every test was done to the current ASTM test methods. The SRV and BOCLE wear test and lubricity test, a fuel stablazation test, a filter plugging test, a cloud point test, and other bench tests. A field test was also performed on 5 different fleets and a total of 113 trucks for 1 year. This was done at the recommended treat level and in trucks that were not using a fuel treatment before the LE test. The results were an increase in fuel economy, no injector fouling, extended injector life, fuel filter life improved dramatically, smoke emmissions were maintained near new injector levels for long durations, and pump life increased.



The SRV test results showed a 21. 4% reduction in the coefficient of friction between standard #2 low sulfur diesel and the same fuel treated with the LE DCI+ (again at the recommended treat rate). The test was done at a 20 newton load.



The BOCLE scuffing test data was as follows (scuffing load, grams)

Fuel A - untreated fuel 3800-treated fuel 4700

Fuel B - untreated fuel 3000-treated fuel 4100

Fuel C - untreated fuel 3500-treated fuel 4600

Fuel D - untreated fuel 3300-treated fuel 4400

Fuel F - untreated fuel 3600-treated fuel 4300



These test results show a 19. 4% to 36. 6% higher scuffing load in grams than just standard #2 diesel from 5 different pump locations. This means less wear for your pump.



Again the BOCLE tests were done at the standard treat rate as per the bottle, or at 1 pint of LE to 125 gallons of fuel.



I hope this sets your mind at ease that at least one oil company out there does not use as you say a different treat rate in testing just to sell product.

Oil Man-



Thanks for that response. It contains exactly the info I wanted. Good to see some companies are comparing apples to apples when it comes to test concentrations and recommended use concentrations.



Thanks,

Dave.
