Two Ways to Save
 "I am looking at formulating a long-drain diesel engine oil predominantly for U.S. engines but without the constraint of CJ-4. What are your views on the relative merits of overdosing a CJ-4 formulation vs. just boosting the detergent inhibitor?"When considering formulating your own diesel engine oil, there are many factors that come into play. First, understand that the CJ-4 formulation places limits on additive levels to protect after-treatment emission-control equipment on 2007 and newer engines. 

These engines are designed to conform to CJ-4 classifications, which still meet all the criteria of older diesel engines using CI-4 and CI-4 Plus. The CJ-4 classification also sets limits to comply with the Environmental Protection Agency (EPA) standards for using new ultra-low sulfur diesel (ULSD) for on-highway diesel engines.Starting in January 2007, the EPA placed tighter limits on the exhaust emissions of diesel engines. 

To abide by these limits, diesel manufacturers began adding after-treatment emission-control equipment such as catalytic diesel particulate filters and oxidation catalysts. The CJ-4 classification was formulated to protect these pieces of equipment.

CJ-4 formulations are intended to protect vital internal engine components while not poisoning the catalysis or blocking the particulate filter. EPA regulations mandate that diesel particulate filters operate for a minimum of 150,000 miles before servicing. Changing the additive formula in the CJ-4 formulation could greatly affect the particulate filters, requiring earlier servicing or poisoning of the catalysis.Ultra-low sulfur diesel has an EPA mandate of 15 parts per million of sulfur. 

What does this mean in terms of engine reliability and running conditions? ULSD has a lower heating value, resulting in worse fuel mileage. Also, due to lack of lubricity, it can cause premature injector wear. CJ-4 was designed for use with ULSD to give added protection from sooting and higher cylinder temperatures.When changing an oil formulation, you hope to enhance a certain property.

 However, what usually happens is that by improving one oil property, you alter other properties in a negative way. Overboosting the detergent inhibitor can have an impact on how the oil disperses deposits or controls friction and wear.  Keep in mind that when formulating your own oil or brewing additives into an already marketed formulation, there is always a give and take. 

When doing so, have your oil tested against the corresponding ASTM test methods and EPA regulations so no harm is done to the engine or the emission-control devices.

Bob along with his wife Misty just recently started a small business in summer of 2015 that specializes in various Performance Products for all engines and mechancial applications. Our niche is to serve the customers in Central WI and beyond. 

Bob has been around truck and tractor pulling much of his life and grew up on a dairy farm.He also served proudly in the military for  23 years and is still serving in WI Army National Guard as a Field Artillery Ammo SGT and has tons of mechanical  and Techinical background. 

Bob is working on  completion of his Bachelors degree on his spare time with Business major and Marketing and Human Resources, Minors.He also has several associate degrees in Supervisory Management, Marketing, Fire Protection/EMT. 

Along with  several technical degrees /certificates in: Basic welding, automotive electrical troubleshooting, Manufacturing Fundamentals, Advanced Blue print reading. And worked in manufacturing as a CNC operator and has 7 years of experience in that field. 

Misty has many years of customer service,with a degree in customer service and loves NASCAR and racing in general. She has even driven a entry level race car in her younger years.And has done the demo derby car thing and even been on the seat of the "Diesel Deere". She also enjoys mud bogs with atv's and trucks along with truck and tractor pulling. 

We own and operate a John Deere Limited Pro Stock Diesel Pulling tractor that we pull circuits in Wisconsin. We decided to park the tractor in 2014  so we could build a small shop and store for the business that we launched out of frustrations with finding parts and products locally. 

In 2017, we hope to bring that machine back out on the track on limited basis, the class and circuit we plan to pull is still undecided at this point. But assured that we will be running quality AMSOIL products in the engine and drive train when it does make the track again.  

We have a small retail store attached to our shop our hours currently are 7 am - 9 pm Monday - Friday, we encouage customers to call ahead as sometimes we may be out making service calls..And shorter hours on the weekends, but we do place our customers needs always first!  And we are building on added service stalls and inventory storage in spring 2017 so we can better serve our customers.
