The Cost of Owning a Diesel – This Product is Not an Option

Diesel Fuel Injector Clean

Diesel Fuel Additives – Not an Option in Diesel Ownership

Years of reviewing the effects of modern diesel fuel, mechanical issues, costs and designs of injectors, pumps, failures keeps the topic of the misunderstood fuel additive fresh in mind.

Impressive In The Field

As an AMSOIL dealer, one product I rank in the top three where overly positive feedback is almost always given at each sale is our Diesel Injector Clean (and lubricant).  Of course many of those sales were started because I suggested to the customer to try our brand over whatever else they were using. And the majority of the time the customer was not using any at all! But the results seem to be instant thus the higher level of feedback.

What To Expect

I could list all the sales info, product points to know, etc. but you can easily find all that in the product listing or technical data sheet (printable PDF). I wanted to state some of the instant feedback and some savings you can expect!

  • Increased mileage beyond any averages AMSOIL claims. I hear 2 to 3 more MPG’s although that’s not advertised.
  • Quieter engine
  • Regens cut in half – That alone is worth it! Unique to AMSOIL’s formula.
  • More power under load – You’ll notice more with the Cetane Boost
  • Solved sluggishness when passing
  • Skip past expected injector failure mileage to next to none
  • RV’s – amazingly easier starts on seldom used engines
  • Longer fuel filter performance
  • Less water buildup in tank

Lubricity

This is the reason it’s not optional. Not AMSOIL but the industry says you need a lubricant added to every tank of fuel.
AMSOIL recently posted about folks using 2-stroke oil in the fuel. They admitted it worked but only offers a fraction of the lubricant needed especially in modern injectors which rely on products with years of development. The results can be in the thousands saved on repair or replacement costs.

A fuel additive supplier who visited at one of our AMSOIL dealer conventions made it clear. He used a 2015 Chevy Durmax diesel for example. He said in 10 year ownership you will ether spend on average $750 on fuel additives or $6000 to $10,000 in injector repair.

Much of the failure is because the fuel or the over the counter additive doesn’t address corrosion within the injector. The wear resulting which is not visible without a microscope can be devastating to your engines efficiency. The injectors these days usually only have 1 to 2 microns of space around them so you cannot afford even the slightest  dirt causing wear or corrosion from a lack of proper additive.

Best way to buy in Sioux Falls

I keep a healthy supply at my shop at Exit 73 and also at Stan Houston’s on W. 12th St.

The best way to buy is get one 16 oz. bottle and the half gallon as the refill. The savings with the half-gallon is like buying four 160-ounce bottles but paying for three. A sight window is on all bottles assisting with the proper dosage.  And the best part is one ounce (1OZ) treats five gallons! It’s a great bargain even at full retail.

Of course you can buy through our website – AMSOIL Diesel Injector Clean Product Code ADF.

We also have 5-gallon sizes for OTR Trucking operations and a small 8 ounce bottle (Case of 6) for passenger car diesels.

 

 

Diesel Fuel Injector Problems: An Easy Solution

Diesel Fuel Wear Graph

Diesel Owners Need to be Fuel (Injector) Experts

It feels like forever ago, but it’s only been 13 years since the U.S. Environmental Protection Agency (EPA) mandated reduced sulfur content in diesel fuel, in 2006.

Boy, were people angry. They knew sulfur helped protect their fuel pump and injectors from failure. Change is scary, and the thought of replacing expensive components even more so.

Diesel fuel injector problems more pronounced today

Fast-forward to today. I rarely hear anyone talking about this. But the problem is even more prevalent now than it was then. Modern diesels demand even more from the fuel pump and injectors than before, increasing the potential for failure. So, why aren’t people still up in arms?

My hunch is they have accepted the new reality. Or, they just don’t know what they don’t know when they buy a new truck today.

Today’s ultra-low-sulfur diesel fuel (ULSD) provides significantly reduced lubricity – a critical property in controlling fuel-pump and injector wear.

ULSD provides insufficient lubricity

While diesel fuel has traditionally had high lubrication properties, the de-sulfurization process that’s used to strip the diesel fuel of the sulfur content to meet ULSD requirements also strips the fuel of some of its organic compounds responsible for lubrication.

The ASTM D975 diesel-fuel standard mandates a minimum lubricity level. However, the Engine Manufacturers Association (EMA) wants the standard to provide for increased lubricity. But, while the EMA claims there’s a problem, it doesn’t carry enough clout to change the specification.

Since 2006, ULSD has accounted for nearly all diesel available in North America. Why? Because the EPA mandated reduced sulfur to curb harmful emissions.

ULSD now contains a maximum of just 15 ppm sulfur, compared to fuel that had up to 5,000 ppm sulfur prior to EPA regulations.

Waxes in diesel fuel lubricate the fuel pump and injectors, helping fight wear. Without them, the highly engineered components in modern diesels, particularly high-pressure common-rail (HPCR) engines, can wear out and cost thousands in repairs.

Today’s highly engineered diesel fuel injectors can suffer from even minimal deposits.

Diesel injector deposits kill performance

They can also develop deposits that interfere with an optimum spray pattern, reducing power and fuel economy.

The editors of Diesel Power Magazine covered the ULSD problem in the April and May 2019 issues.

As reported, the Bosch CP4.2 fuel pump that comes stock on 2011-2016 Duramax engines has led to thousands of catastrophic failures. It has culminated in class-action lawsuits in Texas and California against BoschGM, Ford and other vehicle manufacturers on behalf of individual diesel owners whose vehicles use that pump.

Diesel fuel pump failure costs big bucks

When the CP4.2 fuel pump fails, it instantly contaminates the entire fuel system with metal particulates, costing $8,000 to $12,000 in repairs. The magazine reiterates what AMSOIL has been saying for years:

“The way to be proactive in protecting a CP4.2 equipped diesel from an early demise is being diligent about using fuel additives that add lubricity with every fill-up.”

Diesel Power Magazine

The CP4.2 pump is said to fail because of two reasons:

1) It’s designed with about 20 percent reduced flow volume than the previous generation pump, requiring it to work even harder.

2) ULSD isn’t providing enough lubricity.

 

Our testing of base fuels across the U.S. confirms the second point.

ASTM D975 requires diesel fuel to limit the wear scar in lubricity testing to 520 microns. The EMA, meanwhile, sets its own, stricter requirement of 460 microns.

As the chart shows, many of the fuels (blue bars) failed to limit wear to 520 microns. And none of them met the EMA’s 460-micron limit.

Diesel Fuel Additive lubricity Improvement

Fuel treated with AMSOIL Diesel All-In-One performed far better (red bars). It not only met the ASTM D975 standard, it also met stricter EMA lubricity requirement.

Our diesel additives deliver a healthy boost in lubricity to help lubricate diesel fuel pumps and injectors. The extra lubrication helps prevent wear in fuel pumps and injectors. They’re also great for maximum winter performance, too.

I strongly recommend that all diesel owners use AMSOIL diesel fuel additives with every tank of fuel.
