Is the a good additive for a 1HZ, it's what I use in my 6.7 power stroke

Thanks
 
IMO the new ish low sulfur fuels are trash. While i cant speak directly to Toyota diesel engines (Id love an LHD 80 with an 1HD FT or FTE - theyre the proverbial unicorn farts though, atleast to me they have been :)) i do use additive it in all diesels that ive had. I dont use fuel treatments for any potential mileage gain (although thats nice if/when it occurs) is use them for added lubricity and/or anti-gel when it gets cold. Now that ive rambled enough, i cant see that additive being anything but a benefit for you.
 
I use this when it starts to get cold here in Colorado, ive never noticed in difference in mpg or performance. It does make me feel better about preventing the fuel tank from gelling.

you'll get a lot of different answers, id wager most of them are pretty similar. I picked one that I could pick up in any parts store locally.

FYI I add Stanadyne additive. The price point and ease of delivery via amazon is my purchase approach because it is not a common item on the shelves locally.


As already stated, the objective is to improve lubricity of the ultra-low sulfur diesel that is available. But it does appear to improve MPG too in my Cruiser (with 15B-FT).
On recent interstate trips averaging 71-73mph;

without additive, mpg nominally clustered around 21mpg​
with additive, mpg nominally clustered around 22.5mpg​
Since my objective is improved lubricity, improvement in mpg performance is a nice side benefit.
 
It doesn’t freeze where I live so not worried about that.
Not looking for performance or mileage enhancement.

I run the liquimoly every few tanks and the diesel purge in each fuel filter when i change filters.

I run exactly that stuff for my 1KZ. Only bought a tiny 4oz bottle at first to test and was surprised at how much improvement it made. Now I add it with every dino fill up - R99 I don't bother. Engine is quieter, better acceleration, smoother, less IDI rattle. Very small dose required per tank, very economical. No clue if it's improved MPG any, I don't have any way to measure closely enough to know.

I bought a bunch of laboratory bottles from Amazon in the right size for a dose. Decant from a larger bottle into the dose size bottles, easy to pour a bottle in the tank before filling up, plus now I know I'm getting the right dose. Very easy to over-dose with the "eh, a glug and a half is good enough!" method and waste additive. Some additives, over-dosing is detrimental to performance, too much is not necessarily better.

I run the same stuff with anti gel during cold snaps in the winter. Likely unneeded, my best bud is a truck driver in this area and daily drives a diesel as well, he doesn't add any anti gel and doesn't have any problems.

If you're only looking for lubricity and are in OR or WA, the state's biodiesel mandate adds plenty of lubricity, wouldn't worry about it at all. Not sure about Cali.

If lubricity is the goal, I agree with the 2 stroke oil recommendation. Fuzzy memory here, but I remember seeing a video where someone tested the various diesel lubricity additives along side two stroke oil, and two stroke oil doing well at ~200:1. Would be worth digging up that video and verifying my fuzzy memory.

Hello,

Low sulfur diesel has lesser lubrication properties than regular diesel.

Some engines, especially older designs, have injection pumps and other parts that need some lubrication from the fuel. Low sulfur diesel may not supply enough lubrication for these engines, and an additive is a must.

The description mentions naphthalene as an ingredient. It works both as a lubricant and as a cetane modifier, a compound that it is nice to have.

The 1HZ engine was designed with poor quality diesel in mind. Chances are its injection pump can use some extra lubrication. Like other Toyota engines, it responds well to good fuel and lubrication.

Use that additive and do not look back.

There are stacks on stacks of studies that disprove this.
 
I used additives occasionally hoping to keep the injectors clean.
I have no idea if they did anything or not for my engine. 200k miles in 9 years.

I alternated between these two brands.

Hello,

I would like to see those stacks.

Lubrication is essentially a film of a compound between two moving parts. If the film is too thin, the parts are too close, friction prevails and then heat and abrasion take over. If the film is too thick, the parts may not have enough contact to operate properly.

Hydrocarbons (diesel is a mixture of hydrocarbons) are not good lubricants. They fail to supply the right film thickness for proper lubrication.

Incidentally, a number of lubricating compounds includes sulfur. Molybdenum sulfide grease comes to mind.

When sulfur concentration is neither too high nor too low, it provides some degree of lubrication. This is because a sulfur molecule has the shape of a ring. At molecular level, it can behave like a bearing ball, hence its properties. Certain sulfides share this feature.

Too much sulfur eats up engine components and catalytic converters.

Upon combustion, sulfur (regardless of its concentration) becomes sulfur dioxide, which is emitted to the atmosphere and then becomes sulfurous acid, one component of acid rain. At the temperatures that modern diesel engines operate, it becomes sulfur trioxide and then sulfuric acid. You do not want either of these raining on you. This was the main reason to produce low sulfur diesel.

On the other hand, diesel -and other fuels- includes lubrication additives in its formulation. Sulfur lubrication aside, injection pumps are complex mechanisms that can always use some additional lubrication. A few dollars spent on better quality fuel, or on fuel and an additive are preferable to an expensive reconditioning. Naphthalene helps here as well.

Isn't Dino oil and it's derivatives all just chains of hydrocarbons?

Lots of people swear by adding auto trans fluid at 200:1.
I never bothered with any thing when I had diesels. Unless you're in a third world country, or know for sure they're issues with v fuel available, not sure there's much to be gained

Will it’s not quit stacks and there all for the same source.
I’m guessing that it’s from the the same group that’s pushing ultra low sulfur diesel.

I would be more swayed by some independent studies. 😉

Hello,

Not all hydrocarbons are created equal.

Usually, hydrocarbons that are used for fuel are linear molecules. Some have little branches, but in general their structure remains line-like. They are viscous but not enough fro proper lubrication.

Hydrocarbons used for lubrication have molecules with ring structures on them. You can think of these rings like small bearing balls that tend to adhere to some surfaces and help them slide. I am oversimplifying a bit here but that is a general idea of what they are and how they work. They can be complicated to manufacture.

Then there are special use hydrocarbons, whose molecules can include rings, a mix of linear chains and branches and even elements like fluorine, sulfur and metals. Some are aircraft/rocket fuel, some are lubricants, some are raw material for other compounds. And some are additives.

Manufacturing all three types requires refineries and special equipment, as well as proprietary technology. Even diesel production from crude oil requires some fine tuning, particularly sulfur removal; keeping the right cetane number can be complicated.

A proper additive can do its work at small concentrations, hence the name. A small but adequate number of molecules can, for instance, assist with the properties of the thin film that is at the heart of lubrication.

That some companies take advantage of this to extract money from people is another story. The trick is to have a closer look at the ingredients. Yes, proprietary compounds cannot be disclosed, but by law companies are obligated to state the chemical type of the compounds they use. That is the reason why Material Safety Data Sheets (MSDS) exist. So, if you know where and what to look for, you can tell snake oil from a proper additive.

Hope this helps.

By the way, I swear by engine oil with the right concentration of fluorinated copolymers. It is available from your supplier of choice. MSDS are your friends.

Those were all from the same website, but they're from seven different sources, if you go to that website there is a stack of studies all from different people, you can try to disregard it all you want but at least have an open mind. It was not sulfur to change the lubricity it was initially the process used to lower the sulfur content, however modern Diesel is every bit as lubricating as old sulfur diesel is
