Adequate diesel fuel lubricity is essential for protecting the precision components in modern diesel engines. This is especially true for high-pressure common-rail (HPCR) engines, where increased wear and deposits can interfere with an optimum spray pattern, reducing power and fuel economy. Find out how to keep your diesel engine running strong all year long with premium diesel fuel additives.
Less lubricity
Diesel fuel traditionally had high lubrication properties, but the desulfurization process that helps diesel fuel meet modern ultra-low-sulfur diesel (ULSD) requirements also strips it of the organic compounds responsible for lubrication. Although the ASTM D975 standard for diesel fuel provides a minimum level of lubricity, it’s not as much as the Engine Manufacturers Association (EMA) recommends.
To meet stringent government mandates for reduced emissions, nearly all diesel fuel sold in North America today is ULSD, which contains a maximum of 15 ppm sulfur. Compare that to as much as 5,000 ppm in traditional diesel fuel available prior to EPA regulations taking effect in 2006. Additionally, ULSD is compatible with modern exhaust treatment devices, such as diesel particulate filters (DPF), that further assist in emissions reduction.
The solution to ULSD
The best way to increase fuel lubricity is to use a fuel additive designed specifically for this purpose, like AMSOIL Diesel Injector Clean, Diesel Injector Clean + Cetane Boost, or Diesel 4-in-1, which combines the benefits of AMSOIL Diesel Injector Clean, Diesel Cold Flow and Diesel Cetane Boost in one convenient package.
AMSOIL diesel fuel additives also provide additional benefits designed to keep diesel engines operating at their maximum performance.
The concentrated formula lubricates to reduce fuel pump and injector wear and rapidly targets and eliminates accumulated nozzle deposits, combustion-chamber deposits and internal-diesel-injector deposits found in HPCR injectors to maximize horsepower and increase fuel economy up to 8%.
Diesel Injector Clean + Cetane Boost
Combines the superior deposit-removing properties of Diesel Injector Clean and the cetane-boosting benefits of Diesel Cetane Boost in one convenient package that delivers outstanding detergency, reduces smoke and emissions, improves lubricity and increases cetane and horsepower.
Combines the superior detergency of Diesel Injector Clean, the excellent anti-gelling properties of Diesel Cold Flow and the increased cetane benefits of Diesel Cetane Boost in one convenient package that helps remove deposits and improves lubricity, cold flow and horsepower.
AMSOIL Diesel 4-in-1 is proven to improve diesel fuel lubricity and protect against injector wear based on independent ASTM D6079 testing.
Diesel fuel lubricity is essential for the protection of modern diesel engine components. Keep your engine operating at peak performance with AMSOIL Diesel fuel additives.
An old time diesel shop (one that rebuilds the old school injectors and injector pumps) informed me that Type-F automatic transmission fluid is one of the best and least costly diesel injector cleaners available. It’s almost pure detergent – I’ve even used it to clean my hands when they’re coated in grease (works better than Go-Jo).
No doubt that AMSOIL products are top quality. Just curious how the AMSOIL products might compare from an cleaning effectiveness point-of-view (more so than from a freezing temperature perspective).
I think this would be an interesting comparison.
I’ve heard in the past that mechanics would put ATF in the gas tank to clean the combustion changer when I was a kid. The funny thing is that it’s very rare you hear these stories. My biggest concern is that ATF was not designed for that specific task. If it was, you would hear it a lot more. I am more concerned about what it’s doing besides cleaning injectors out at a combustible temperature?
The reason for the injector cleaners is not just to clean them, they also lubricate the fuel system as well. These specific cleaners do many things besides just clean, they promote longevity in the fuel system. For diesels that’s a huge benefit. Now it might just be that ATF does just clean, however it doesn’t lubricate the fuel system such at the pump.
I’m all about saving money if I can especially finding new tricks. I’m a bargain shopper when needed. There are unfortunately just some things you can put a price on.
Keeping my fuel system tip top on my lbz Duramax is key to lasting a long time as well as any diesel. Fuel is a huge factor in the functionality of diesels.
It was nice hearing about ATF to clean with again; it brought back some old memories with some really cool people growing up around. I’m with you in the testing, I think that would be a cool idea to see what ATF actually does.
I have used all in one and it works great.
But I would like to see this product be more concentrated.
It gets very expensive considering how much you need to add to a tank of fuel.
It makes it too expensive to use at every fill up.
Pls fine a way to make it more concentrated or lower the price.
I had to switch to a competitor because of the price.

Great info. Thank you
As Mr. Rob Mcginley wrote “All in one” comes too expensive for everyday use. When I compare my cost of less than $7 to treat ~120 gal. in ‘big rig’ with competitor’s additive to price of AMSOIL’s fuel additive it’s obvious who’s gonna win. To clear things up – benefits of both additives to are pretty much similar.
Hi Djordan,
We’re the first to admit that we’re not going to win the head-to-head battle on price. Our goal is superior performance and protection, not lowest price. Even so, consider AMSOIL Injector Clean as an option. It isn’t formulated with the cold-weather benefits of Diesel All-in-One, meaning it’s less expensive.
