When it comes to picking up a diesel fuel additive there are a ton of options. Do you get the cheapest one or do you get the most expensive? Store brand or name brand? So to clear up some of the confusion around diesel fuel additives we have scoured the parts stores and the web in search of the best diesel additive for your truck. The following products were validated not only by our own research but also by many reviews submitted in store and online. In the article you will also find links to the products discussed at the best price we were able to find.
A good diesel fuel additive will assist the vehicle by reducing hydrocarbons, clearing the DPF and lubricity for fuel injectors. Understand that additives offer no performance benefit and should be used in moderation, typically every two months. Modern diesel fuel is low sulpher which eliminates previous issues of excess build up and contamination.
Additionally, diesel owners may be concerned about diesel fuel gelling associated with freezing temperatures. Fuel distributors help alleviate this concern by mixing diesel fuel for specific regions to reduce diesel gelling occurrences. If concerned about diesel fuel gelling, make sure to see our recommendations on diesel fuel anti-gel products.
Before picking any of the below products, be sure to adhere to the recommendations of both your vehicle manufacturer and the product manufacturer.
Lucas Oil – Diesel Deep Clean
Lucas Oil products are probably one of the most well known producers of fuel additive products. They have offerings for most all applications in the consumer, heavy duty and motorsports markets.
The diesel deep clean by Lucas doesn’t make obscure promises or give any misunderstandings. This diesel fuel additive product aims to reduce particles that typically cause diesel particular filters(DPF) to become clogged. By doing this it reduces the frequency of emission system regeneration processes. These regen processes are normal but excessive regens can lead to premature part failure.
Users of Lucas Diesel Deep Clean have found the product to assist in reduced soot buildup and some have claimed that it has revitalized their engines. In our research we found that amazon had the best price, check now to confirm.
Power Service – Diesel Kleen
Power Service products have been around for many years serving diesel enthusiast. The Diesel Kleen product is one of the favorites used by repair shops around the country. Power Service solely focuses on diesel related products created to solve frequent fuel related issues.
Diesel Kleen’s major focus is on cleaning underperforming fuel injectors. After many cycles fuel injectors can become less efficient due to build up. Diesel Kleen also lubricates fuel system components reducing wear and tear.
Power Service recommends adding Diesel Kleen every time you fill up but in our opinion that’s not necessary. The only scenario that might warrant adding this product at every fill up would be if you had an older model diesel with many miles. Again, the best price we found at the time of this article was Amazon, check it out!
Hot Shots Secret – Diesel Extreme
Diesel Extreme fuel additive is another top pick among diesel owners and operators. The formula of the Hot Shots Secret product was developed through years of work by Chris Gabrelcik founder and CEO. Chris started Lubrication Specialties, Inc.(parent company to Hot Shots Secret) in his garage in 1997. Hot Shots Secret offers a multitude of products for diesel trucks, from fuel additives to antifreeze.
Hot Shots Secret Diesel Extreme product covers the gamut when it comes to common modern diesel fuel system issues. The first area of coverage comes with taking on regen processes associated with DPF equipped vehicles. This is done by increasing cetane to provide a cleaner burning fuel which in turn lessens the hydrocarbon solids that would typically clog the DPF. This additive also works in cleaning clogged injectors, which bog performance. By cleaning the injectors Diesel Extreme helps restore injectors to a higher operating range.
Diesel Extreme also boast a moisture dispersant that prevents freezing down to -9 F. While most people may not buy this product for this reason its an added benefit of this additive. Another feature of this product is that the manufacturer, Hot Shots Secret, only recommends use twice per year. This will be appealing to those that do not wish to use a diesel additive every other month.
Diesel Extreme can be found at a number of retailers but again, we found the best pricing on amazon. Check it out!
Stanadyne – Diesel Fuel Additive Performance Formula
Rounding off the list of preferred diesel additives is the Performance Formula offered by Stanadyne Fuel Additives. Stanadyne Fuel Additives is a branch of Parker Hannifin, a global leader in motion and control technologies. Unlike the other additive providers, the core company of Stanadyne is not a petroleum additive manufacturer. It appears the Stanadyne brand was created by Parker as a solution to issues they may be having among their equipment. As this is purely speculation it is definitely plausible as this has been the case with many popular products. But it would appear that the product worked so well that offering it to consumers was a no brainer.
Stanadynes diesel additive is more of a mild, all in one product. A feature of the Performance Formula is detergents specifically included to break down fuel system grime. This additive also has the added benefit of helping to demulsify water which in turn makes easier work for the water separator. It has also been noted that with periodic usage Internal Diesel Injector Deposits have been minimized which in turn assist better performance.
Stanadynes Performance Formula can be found on Amazon at a competitive price, take a look!
Do You Need A Diesel Fuel Additive?
The thing about fuel additives is that people often think that they are a mechanic in a bottle. Diesel fuel additives allow owners to keep their engines running in proper form but will not repair a failed fuel pump etc. These additives ensure consistent fuel system operation when used as part of a maintenance routine. Some manufacturers, like GM, specifically state that these diesel additives are unnecessary and recommend against their use. GM only recommends a specific AC Delco additive to assist in removing water from fuel.
So, do we think that you need a diesel fuel additive as part of your truck maintenance routine? Definitely, but be sure to not over do it especially with newer modal trucks. Fluids other than pure diesel fuel can affect seals, gaskets and pumps adversely if used in excess. So our recommendation is to make sure you adhere to warranty recommendations by your manufacturer and if you do use diesel additives do so in moderation.
Let us know, did we cover your favorite fuel additive or did we leave it off? If we missed it, let us know why you enjoy that additive so much and it may get added to our list.
