Q: Which product should I choose?

Opti-Lube XPD is our most popular product, with the highest level of lubrication, with ingredients to boost cetane and prevent gelling in cold weather.

Opti-Lube Winter Diesel Fuel Improver is suggested for extreme cold climates, where temperatures regularly fall below zero.

This product also contains a cetane improver and provides excellent lubrication.

Opti-Lube Summer/Warm Climate Blend provides excellent lubrication, and does not contain anti-gelling protection or a cetane improver. Because of the low treatment ratio (3000:1), this is our most economical product.

All Opti-Lube Diesel Fuel Improvers clean injectors, improve water separation, prevent fuel system corrosion and improve fuel economy.

Q: Does it void my new vehicle warranty?

A: No, our fuel improvers are completely compatible with all currently produced vehicles and equipment. No damage will be caused, only benefits

Q:How much does it cost?

A: In most cases, Opti-Lube Diesel Fuel Improvers more than pay for themselves through improved fuel economy.

The real savings is realized through protection and extended life of equipment.

Approximate cost to treat each gallon of fuel:

XPD: 07¢ to 15¢

Winter Blend: 08¢

Summer/Warm Climate Blend: 02¢ to 04¢

Q:  What types of engines can it be used in?

A: Virtually any type of Diesel engine. All Diesel engines benefit from the features in Opti-Lube Diesel Fuel Improvers, including those with the latest emissions equipment.

Q: What is the treatment rate?

A: This varies by product, please see individual instructions.

Q:   Can it be used with other fuels?

A: All commercially available fuels will be improved by Opti-Lube Fuel Improver. Our testing shows full compatibility with Bio-Diesel, up to B20. While not designed for gasoline, some customers have reported a gas mileage increase when XPD is added in small quantities (1oz per 5 gallons).

Q: Does Opti-Lube Fuel Improver contain Alcohol, Teflon ® (PTFE) or other solids?

A: There is no Alcohol and no Teflon ® or any other solid particles in our fuel improver.

Q: What is cetane, and why boost it?

A: Cetane relates to how readily diesel fuel will combust in the cylinder, higher numbers are better. The cetane in modern fuel is reduced by the removal of sulfur (producing ULSF) and winter blends of fuel, which frequently have kerosene added. Improving cetane helps engines to start easier, and burn fuel more efficiently.

Q: How should I add the product to my fuel

A: Most customers add half (or more) of the estimated amount before fueling, then the remainder just before the tank is full. The products easily disperse throughout the tank, no mixing is required.

Q: Is there a benefit to adding more than the recommended amount?

A: Fuels vary greatly by supplier, region and season. Typically no benefits are found above the recommended maximum rate.

Q: Are these products compatible with ULSF

(Ultra Low Sulfur Fuel) and my vehicle's emissions equipment

A: Yes, Opti-Lube Diesel Fuel Improvers contain no sulfur, and are completely compatible with late model emissions equipment, including 2013 vehilces. Regeneration of the Diesel Particulate Filter may happen less frequently, since Opti-Lube treated fuel is burning more completely than untreated fuel.

Q: Does it do anything besides reducing wear & friction?

A: These are multi-functional additives, each product improves water separation (a demulsifier), prevent corrosion, improve storage life and clean injectors. The XPD and Winter products boost cetane and contain anti-gel additives. Each product has been found to improve fuel economy in most cases.

Q: Can it be used in older or newer vehicles?

A: All Diesel Engines will benefit. Of note, older Diesel Engines were not designed to run on ULSF, so using a lubricating additive is very important to extending equipment life.
