How much fuel additive should I use in my diesel engine?
The correct treatment ratio depends on the specific product and your application.
For example, a ratio of 1:1,000 means using 1 gallon of additive for every 1,000 gallons of fuel. Smaller measurements can be calculated for smaller tanks and equipment.
Primrose 5007 may be used at a stronger initial treatment ratio of 1:250, followed by 1:1,000 for regular maintenance or 1:2,000 for continued cost savings, depending on operating conditions and fuel quality.
Always review the product instructions or contact ASJ Products if you need help selecting the right treatment ratio for your equipment.
What does the treatment cost per gallon?
Treatment cost varies by product, dosage, and package size.
A typical competing product may treat approximately 100 gallons at a cost of around $0.20 per gallon treated. Primrose products may treat 250 to 500 gallons at approximately $0.04 to $0.08 per gallon treated, depending on the product and treatment ratio.
This can provide stronger value when comparing the actual amount of fuel treated rather than only comparing the price of the container.
I currently buy fuel additive for less per quart. Why would I pay more for Primrose?
The container price does not always reflect the true treatment cost.
For example, a competing product priced at $11 per quart and treating 100 gallons costs approximately $0.11 per gallon treated. Primrose 5007 priced at $23 per quart and treating 250 gallons costs approximately $0.09 per gallon treated.
Because Primrose products are highly concentrated, they may provide a lower cost per gallon treated while delivering broader fuel-system benefits.
What is the difference between Primrose 5007 and 5002?
Both products are designed to support diesel fuel-system performance.
Primrose 5007 provides a stronger cetane improvement, which can support combustion quality, engine performance, and exhaust characteristics. Primrose 5002 is generally manufactured and supplied in larger bulk-container quantities.
Contact ASJ Products if you need help deciding which product is best for your equipment, storage capacity, or fuel-treatment program.

What is cetane in diesel fuel, and why is it important?
Cetane is used to describe how readily diesel fuel ignites under compression. It is measured using the Cetane Number.
In general, a higher Cetane Number can support faster ignition, smoother combustion, improved cold starting, reduced smoke, and better overall engine performance. The minimum diesel Cetane Number in the United States is typically 40.
Primrose 5007 is designed to increase the Cetane Number by up to 4 points, depending on the fuel and treatment conditions.
Isn’t all grease basically the same?
No. Grease quality can vary significantly based on the base oil, thickener system, additives, temperature performance, water resistance, load protection, and pumpability.
Premium Primrose greases use high-quality paraffinic base oils and oil-soluble Moly-D friction-reducing technology. Because the Moly-D remains oil-soluble, it does not settle out like some solid additives can.
Many customers report reduced grease consumption and longer service intervals, although results depend on the equipment, operating environment, maintenance practices, and application.
What grease should I use in an automated lubrication system?
Primrose 357 Armor Plate with Moly-D is a strong option for many automated lubrication systems.
Its oil-soluble formula is designed to maintain consistent pumpability, reduce the risk of clogging, and perform across changing temperatures. It can be a good fit for construction, agricultural, industrial, fleet, and other equipment using centralized or automated grease systems.
For the best recommendation, include your equipment type, operating temperature, current grease, and system requirements when contacting ASJ Products.
