Frequently Asked Questions

Are BioBlend lubricants compatible with conventional petroleum lubricants?

Yes. BioBlend lubricants are compatible with most conventional petroleum lubricants – if you have a question on a specific product, please contact us regarding your specific requirements.

Will biodegradable lubricants biodegrade in my equipment?

BioBlend lubricants will not biodegrade in your equipment. Air, water and micro-organisms found in the soil and water are needed to complete the process.


What is the definition of an Environmentally Acceptable Lubricant (EAL)?

There are many terms: Environmentally Friendly, Green, Eco-Friendly and other undefined terms that are used in the industry by various companies. These terms have no relationship to qualifying as an approved EAL. There is an approved definition of an Environmentally Acceptable Lubricant (EAL) by the US EPA. This definition is used in the 2013 Vessel General Permit for the Marine industry. That definition says that to be classified as an EAL, the product must be ultimately biodegradable, have low toxicity and non-bioaccumulative. The standard also lists the tests that are acceptable to show that a product meets these standards. Many BioBlend products meet this definition and we have the test data from independent labs to support these claims.

Do I have to accept lower performance levels while getting the environmental benefits of BioBlend lubricants?

No. BioBlend lubricants have excellent lubricity, high viscosity index levels, and can reduce wear, friction, and operating temperatures. In many cases, BioBlend lubricants perform better than products manufactured using petroleum base oils.

What is the shelf life of biodegradable lubricants?

The shelf life of biobased lubricants has been dramatically extended with the use of the latest additive technologies. BioBlend lubricants typically have a warehouse shelf life of 18-24 months and can be used in field applications well beyond that time.

Do biodegradable hydraulic oils have to be changed more often than petroleum lubricants?

The life of any hydraulic oil depends on many factors which include operating conditions and contaminants. BioBlend hydraulic oils have performed well in field applications for extended periods of time. We recommended following the manufacturer’s guidelines for lubricant change intervals. We do not recommend shorter change intervals for our products. By utilizing oil analysis and good maintenance practices customers may in fact be able to extend drain intervals.

Do biodegradable hydraulic oils have difficulty handling water intrusions in oil systems?

Water in a biobased oil hydraulic system is as bad as water in a petroleum lubricant based hydraulic system. In both cases 200-300 ppm of water will deplete some additives, react with others to form corrosives, reduce film strength, clog filters, increase air entrainment, and increase the likelihood of cavitation. The bottom line is that all hydraulic systems have difficulty with high water levels and steps should be taken to lessen the water content in these systems.

Can biodegradable oils handle high pressures in hydraulic systems?

Yes. BioBlend hydraulic oils can handle the same typical hydraulic oil pressures petroleum lubricants experience in hydraulic systems.

Will the seals / gaskets / o-rings in my equipment perform the same with biodegradable oils as with petroleum based oils?

A material compatibility guide can be found here as well as additional information from the Parker-Hannifan O-Ring Guide.

Are BioBlend products warranted?

BioBlend warrants that BioBlend branded lubricant products manufactured and marketed by BioBlend (“BioBlend Lubricants”) will conform to the written specifications for the BioBlend Lubricants as set forth in the product data sheet as in effect at the time of sale and will comply with the written product performance claims for the BioBlend Lubricants contained in the product data sheet as in effect at the time of sale. For full details, see our Product Limited Warranty statement.

Can I add a BioBlend product to an existing piece of equipment (if they are the same basic product and viscosity) without flushing out the entire system?

Yes in most cases, however you will lose some product specific performance and environmental advantages.

Are biodegradable lubricants able to be re-refined?

Yes, however it is recommended to make your re-refined vendor aware that you are including a Group V base oil in the waste stream.

Can BioBlend lubricants be used in waste oil heating systems in my shop?

Yes as along as you follow recommended OEM directions.

Are BioBlend products compatible with Poly Alkaline Glycols (PAG)?

In many cases they would be compatible. However, we highly suggest a specific discussion on the exact products in question with BioBlend technical services prior to final determination.
