Customers sometimes ask whether a diesel fuel additive can improve fuel economy. The most honest answer is that results vary. Fuel quality, driving habits, vehicle condition, route, load, weather, and maintenance can all affect mileage.
Choosing the right diesel fuel additive depends on your main concern. Some customers want one all-around additive. Others are focused on maximum lubricity, stronger cetane, cold-weather protection, or a one-time fuel system cleaning treatment.
If your diesel feels down on power, seems louder than normal, smokes more than usual, or has lost fuel economy, fuel system deposits may be part of the problem. They are not the only possible cause, but they are common enough to be worth considering.
In short: yes, Opti-Lube diesel additives can generally be mixed. The main thing to remember is that each product is designed for a purpose, so mixing products is not always necessary.

Cetane relates to how readily diesel fuel ignites during combustion. In simple terms, a higher cetane number usually means the fuel ignites more easily and with less delay after injection.
A higher cetane number can help improve cold starts, red...
Agricultural diesel equipment often has a different use pattern than daily-driven vehicles. Equipment may sit for long periods, run hard during certain seasons, and rely on stored fuel from bulk tanks.
Diesel fuel can gel in cold weather when wax naturally found in the fuel begins to crystallize and restrict flow. This most often shows up as filter plugging, hard starts, loss of power, or a no-start condition.

Diesel fuel does not last forever. Over time, oxidation, water, heat, microbial activity, and contamination can cause diesel fuel to darken, form sediment, plug filters, and lose performance.
Water in diesel fuel is a serious concern. It can contribute to corrosion, filter plugging, microbial growth, injector problems, and fuel system wear.
An emulsifier helps disperse water into the fuel so it rema...
One of the most common questions we get is: what is the difference between your diesel fuel additives? The short answer is that each product is designed for a different need.
