This is sound advice from an article by Noria Corporation.
“What are the consequences and/or benefits of mixing synthetic and non-synthetic oil in an engine crankcase, or any other application such as a gearbox? I have been told that a crankcase can be drained of non-synthetic oil and synthetic oil can be added without flushing any of the prior oil residue.”
In general it is never a good idea to mix two different oils in any application. If this is unavoidable, there are two major concerns, specifically incompatibility between the base oil, and incompatibility between the additives. The overwhelming majority of synthetic oils, particularly crankcase oils are PAO based.
From a base oil standpoint, there are usually no problems with mixing a PAO synthetic and a mineral oil since both are hydrocarbon based and chemically very similar. However, extreme caution should be used if the synthetic oil is non-hydrocarbon based.
As for additive incompatibility, the biggest danger is mixing oils with very different additive packages, particularly mixing those with acidic additives, such as most AW and EP oils, with oils containing alkaline additives commonly used in crankcase oils. In this case, mixing can result in a number of problems including additive drop out, loss of demulsibility, foaming problems and reduced oxidation stability.
The best approach is to select the appropriate lubricant for the application at hand and stick with it! If you are forced to mix oil of different types, it is important that either the lubricant manufacturer is consulted and/or compatibility testing is performed to avoid potential problems.

Case IH uses technology to lower emissions
By Heather Thorstensen

Bill Whitworth, a sales manager for Case IH, says 2011 Magnum and Steiger models use technology to meet new regulations for lower emissions. The new diesel exhaust fluid tank, part of the system to lower emissions, is visible on the Steiger in the background.
KASSON, Minn.— Case IH’s 2011 models of Magnum and Steiger tractors now at dealerships are the company’s first models required to meet the latest emissions regulations.
The U.S. Environmental Protection Agency’s Tier 4 regulations reduce the amount of particulate matter, nitrogen oxides and non-methane hydrocarbon that may be emitted in new non-road diesel engines. The rule was created to improve air quality and reduce health risks for people and animals. Canada and European countries also have emissions regulations.
Case IH is using two types of technology to meet Tier 4 regulations.
Tractors with more than 100 horsepower will use selective catalytic reduction, or SCR. This system treats exhaust gases with a diesel exhaust fluid. The chemical reaction turns exhaust into nitrogen gas vapor and water.
Tractors under 100 horsepower will use exhaust gas recirculation, or EGR. This system puts exhaust back into the engine and uses a filter to capture particulates.
Bill Whitworth, southern Minnesota and northwest Iowa sales manager for Case IH, said SCR will provide the best engine performance on their medium- to heavy-duty tractors.
Not recirculating exhaust back to the engine will allow it to run longer between maintenance stops and it improves fuel efficiency, said Whitworth.
It’s estimated SCR provides a 10 percent boost in fuel efficiency compared to EGR, he said.
A drawback of SCR is it requires the user to purchase diesel exhaust fluid, or DEF, which will be sold by Case IH dealers. DEF is approximately 33 percent synthetic urea and 67 percent deionized water.
DEF’s price will vary by Case IH dealer. It’s sold in 2.5 gallon containers, 55-gallon drums, 275- or 330-gallon totes or bulk size containers. Minnesota Ag Group in Kasson was recently selling 275-gallon totes for $3.89 per gallon.
The DEF tank will need to be filled every other time the diesel tank is filled. DEF tank sizes range from 15 gallons to 64 gallons, depending on the model.
It’s non-toxic, but operators will want to wash it off if it gets on them, said Whitworth. It has a shelf-life of up to two years when stored at room temperature. The system is designed so that DEF doesn’t freeze in the machines’ lines.
Case IH says the technology has proven itself reliable through a partnership with Fiat Powertrain Technologies, an engine manufacturer that has made SCR engines for worldwide customers since 2006.
Case IH’s light- to medium-duty tractors will use EGR systems because those tractors use less fuel. The boost in fuel efficiency that an SCR system would provide won’t make as big of an impact, said Whitworth.
Case IH sees itself as ahead of the curve by putting SCR technology in their larger tractors. According to company literature, some industry engineers say tractor engines will need SCR on medium- to heavy-duty engines to meet final Tier 4 regulations that will start to be phased in by 2014.
Both 2011 Steiger and Magnum models also feature new hoods and engines.
Kobelco Machinery has put out a website dedicated to their solution to the EPA Tier 4 mandate. Below is a picture of their SCR system, and I also provided a link to their Tier 4 Solution website.

What is Diesel Exhaust Fluid (DEF)?
Here at Pynergy Petroleum we have been getting a lot of phone calls and emails regarding Diesel Exhaust Fluid. What is it, do we sell it, how do I store it, etc.? The good news for our customers is that we have been selling Diesel Exhaust Fluid (DEF) to our customers for the past two years, and as a result we have the experience and knowledge that has earned us the respect of our customers and competitors.
What is DEF?
Whether you have or not, it is likely you will soon be driving vehicles that will require this operating fluid. DEF is a non-hazardous, non-toxic, nonflammable, non explosive fuel and is, therefore, very safe to use. DEF is an operating fluid for a new engine technology – it is not a fuel nor is it mixed with fuel. DEF is a high purity solution of urea in water (32.5%), and is used to reduce NOx emissions from trucks and buses powered by diesel engines that use Selective Catalytic Reduction (SCR) technology.
What is SCR?
SCR technology reduces emission of the NOx emissions of the NOx gases that are produced inside the engine during combustion. This process requires the correct injected volume of DEF into the exhaust stream. DEF is sprayed into the exhaust, where it is subsequently hydrolyzed before the catalytic converter breaks down nitrogen oxide (NOx) into harmless (N2) and water (H2O).
Why did things change?
It’s all about improving the environment. Over the last 15 years or so the emissions from vehicles have had to meet increasingly lower limits. In the USA, emissions from vehicles are regulated by the EPA’s Clean Air Act. The use of SCR System for NOx reduction is an efficient way to meet these regulations, which went into effect on January 1, 2010 and sets the NOx emission limits at 0.20 g/bhp-hr. Pre 2010 diesel engines relied on EGR technology to meet emission standards; however, this technology had limitations on meeting this new standard as well as the continued reduction in fuel economy due to how this system works.
Availability?
Pynergy Petroleum Company has partnered with the world’s largest manufacturer of DEF, Yara. Yara’s brand of DEF, Air1, has been at the forefront of this technology and has gained global accolades for their product quality and supply chain protocols. Pynergy Petroleum Company represents the Air1 brand throughout most of Colorado and SW Wyoming with a full line of DEF products and DEF dispensing equipment. We currently can supply you with 1 gallon and 2.5 gallon jugs, 55 gallon drums, 275 or 330 gallon totes or Bulk DEF.
If you have new vehicles that require DEF in your fleet, or will have units coming in soon we would appreciate the opportunity to help you with all of your DEF and dispensing equipment needs.
Happy Holidays,
