Diesel Additive

[Billet Bee]

Thanks John, it was opti lube I was thinking of. Hot shot and opti lube are the to two go tos. Either would be a major improvement in lubricity amongst other claims

If I still owned a diesel vehicle, I sure would be spiking. We have crap fuel here in Minnesota - I know because we tested it in our powergen manufacturing facility.

If you're fortunate to live in a state that mandates quality standards above the bare minimum Federal, that's great. For those of us that don't or travel between states, I'd be doing all I can to protect that expensive fuel pressure pump. Bosch has a stranglehold on this market.

US crappy diesel is at the heart of the current pump issues,(these same cp4 pumps have few issues with euro spec diesel) I believe failure rates are around 1% w/euro diesel and around 8-9% with us spec diesel.... there have been many new developments in the additive world in last couple of years and as mentioned, even some of the oem`s are starting to recommend them!

You have proof of this?

An interesting incomplete question.
Proof of what? He made a lot of statements (that I believe are true). You can Google, or search the forums, for any subject and get "proof", however, not sure what proof you are looking for.

Ah...the snake-oil salesman.

He said "I believe failure rates are around 1% w/euro diesel and around 8-9% with US spec diesel". When someone says "I believe" it simply means they are just pulling figures out of their ***.
I am simply asking for proof of where he got those numbers.

The numbers and overall info were sourced from multiple sources via internet search!
If you do your OWN SEARCH you will find lawsuits pertaining to the issues with the cp4 pumps, both the oem`s against Bosh (the pump manuf) AND truck customers suing the oem`s for not honoring their warranties, by their (oems) claim that customers used contaminated fuel, thus causing the pump failure!

Based on lotions and potions in years past I get your skepticism, however, if you take the time to do your own search you will find that the cp4 pump issues are all too real, AND the newer developments in additives have merit.

Btw, you can keep the "********" to yourself! TROLL!

Gotcha
I thought that when he said "I believe" it's because he knows there's a difference but not sure of the exact numbers. Also. you could take that statement out of his post and it wouldn't change a thing as it was just reinforcing his comment about our crappy fuel compared to Europe's which is true.

I believe that is a Hot Shuts promotion test
What's missing is a Hot Shots comparison to Opti Lube's XPD which has much more lubricity than their XL.

I'm not knocking Hot Shots as it is a great product. I use it, like it, and recommend it. Hot Shots is comparing their best, they should be testing against Opti Lube's best. But that's marketing and why we are told: "buyer beware".

BINGO!

 

[HEMIMANN]

Well, I had proof from work testing some years back. But apparently, people are distrustful inside an enthusiast group, so you don't need to comment here any further. Move on.

Someone making claims and quoting numbers should be ready to back those claims with fact. Not just "I believe".
It is not up to us to look for data verifying his claims.

The info is out there, get off you *** and do a search for yourself, not going to spoon feed you like a 2 year old....

You're the one spewing BS without any facts to back up your claims. Guess we should just take you at your word because you "believe"?

If you are so adamant why don't you try disproving the comment? All this crap over nothing is ridiculous. Apparently you just don't get it.

Here is the other test that uses opti lube xdp. Compare this link with the hot shot LX4 link, both are phinominal, but not shot lx4 wins out with a lower wear scar rating of 270-280 Compared to xdp 315ish

I think it would very hard to get that kind of information and even then it would be even harder to publicly publish it or link it in a forum. You may find third party report or a link here and there, but up to date data would be hard to find.

When I worked at Cummins, we tested many different fuel standards and additives in our engine dyno cell tests. Of course there were improvements with various additive packages in both efficiency and wear. However, efficiency was only improved to a certain extent. Even if I still worked at Cummins I could not publish any data and would get fired if I did.

I currently have tons of MacKay & Company data at work that shows failure/replacement rates of may different parts on class 6-8 trucks, but I cannot publish that info due to agreements we have with MacKay. I also have tons of service data from our 130+ Peterbilt, Navistar, Ford, Hino, Isuzu, and Bluebird bus dealerships nationwide. I have even more data in our 1,500+ class 2-5 truck fleet nationwide(many of our class 3-5 service truck are diesels), but again it is not data I could publish on a forum.

In regards to additive testing when I was at Cummins, many Cummins engines are tuned for the federal fuel standards of 40 cetane. Using an additive that increases the cetane past what the diesel is tuned for will not show much improvement with the stock tuning just like it would not if you put high octane gas in a car that only required regular. My BMW diesel car on the other hand recommends 50 cetane for best efficiency since that is what it is tuned for in stock form. I definitely noticed a difference in both power and efficiency when traveling to other states that have a lower 40 cetane rating versus 48 here in Texas.

As far as wear. I would not be too concerned with the CP3 pump, but I would probably be more inclined to use additives a lot more if I had a CP4 and lived outside of Texas. The design of the CP4 is considerably more sensitive to fuel contamination than the CP3 is. If extra additives on top of what the fuel supplier adds to the fuel can decrease my chances of having $10k repair bill like my brother had with his 2012 F350, then I would not hesitate to use it. Some may say it is wasting money, but my professional experiences working for various vehicle and engine manufacturers says it is not.

I worked at Cummins also, in the PowerGen Division in Minneapolis. We used the G-Drive constant speed engines, and also sold to military where they used JP-4 & JP-5. These guys come on this site and don't believe us then cause trouble. Wish they'd get banned.
