CITGO offers a complete line of Diesel Engine Oils that offer optimum performance for diesel fuel. CITGARD and SynDurance are recommended for diesel fuel powered engines.

Q: What type of engine oil does CITGO recommend for Detroit Diesel Two Stroke Engines?
A: CITGO CITGARD 500 40 would be recommended for this application. Detroit's primary recommendation for 2-strokes is API CF-2; SAE 40 weight; and sulfated ash of 1.0% maximum. It is important to refer to the Detroit Diesel lubrication Guide for the proper viscosity and temperature range recommendations.

Q: What is meant by API CJ-4?
A: This is the newest heavy duty oil specification that is required for 2007 model year trucks in conjunction with the EPA's On-Highway 2007 Exhaust Emission Standards that require a reduction in nitrogen oxide and particulate matter CITGO offers a family of high performance diesel engine oils for both new and older diesel engines, CITGARD 700, CITGARD 700 Plus, and SynDurance that meet CJ-4 performance category. SynDurance also offers additional fuel economy and improved cold weather lubrication.

Q: Is CITGO CITGARD 600 15W-40 rated API CJ-4?
A: While CITGARD 600 15w40 is CJ-4 capable it is rated and approved as CI-4 Plus. CITGARD 700, CITGARD 700 Plus, and SynDurance meet the CJ-4 performance category. SynDurance also offers additional fuel economy and improved cold weather lubrication.

Q: What CITGO product meets this new heavy duty oil standard?
A: CITGARD 700, CITGARD 700 Plus, and SynDurance meet the CJ-4 performance category. SynDurance also offers additional fuel economy and improved cold weather lubrication.

Q: I have a mixed fleet of older and new equipment. Do I have to stock two different grades of oil, one for new engines and one for older unites?
A: No, the new CITGO CITGARD C700, CITGARD 700 Plus, and SynDurance are designed to be backwards compatible. Meaning, if your older units call for API CH-4, CI-4 or CI-Plus then the only crankcase oil you would need to stock are one of CITGOs CJ-4 approved oils.

Q: What would happen if older CI-4 or CI-4 Plus oil was used in new 2007 EPA compliant engines?
A: Because of the higher levels of sulfated ash, phosphorus and sulfur used to formulate these previous types of oil, there is a risk of plugging the diesel particulate filters (DPF) and could cause more frequent maintenance of the low emission exhaust system. In addition, the older chemistries may not be able to handle the higher temperatures and increase in exhaust gas being pumped back into the crankcase on the new 2007 EPA complaint engines. CITGARD 700, CITGARD 700 Plus, and SynDurance meet the CJ-4 performance category. SynDurance also offers additional fuel economy and improved cold weather lubrication

Q: Does CJ-4 apply to off-high-way equipment?
A: At this time it only applies to on-highway vehicles beginning with model year 2007. Customers who want one oil for both on and off highway or have new 2007 engines should use CITGARD 700, CITGARD 700 Plus, and SynDurance that meet the CJ-4 performance category as well as all previous categories. SynDurance also offers additional fuel economy and improved cold weather lubrication. Additionally emission requirement in certain areas of the country have mandated that the off road equipment meet tier 3 emission requirements which require CJ-4 oils.

Q: Can I use CJ-4 oil in off road equipment that is not burning ultra-low sulfur diesel?
A: Yes, the CITGO C700 15W-40, CITGARD 700 Plus, and SynDurance can be used. These oils have proven to offer excellent protection when using high sulfur diesel fuels. However, because of the higher sulfur content of the fuel being used extending drain intervals would be discouraged unless proper oil analysis testing is being performed on the used crankcase oil. CITGO offers its patented LubeAlert Oil analysis to provide the information for proper drain interval recommendations.

Q: What is meant by the TBN of oil?
A: TBN stands for Total Base Number, which is a measure of how well the oil can neutralize acidic combustion by-products. The higher the TBN of new oil is not always a good indicator of how well the TBN will last when the oil is subject to extreme heat and corrosive exhaust gases. (TBN retention) Some oils with high starting TBNs are used up very quickly leaving little protection against corrosive by-products that form in the used oil towards the end of the drain cycle. CITGARD and SynDurance heavy duty diesel engine oils have proven to offer excellent TBN retention and corrosive wear protection under severe operating conditions and extended service intervals.

Q: Will a single viscosity grade oil like the CITGO CITGARD 600 40 provide better protection than a multi-grade 15W40?
A: Multi-grade oils have the advantage of providing quick start-up protection when the engine is cold. In a cold engine the 5W or 15W multi-grades will start to flow and circulate much quicker providing better protection in a cold starting engine. During initial start up and during the first few minutes of operation is a very critical time when the majority of engine wear is often experienced. In addition to initial start up advantages, engine builders have proven that multi-grade engine oils reduce oil consumption and critical engine area deposits when compared to monogrades. For maximum protection in modern diesel engines use: CITGARD 700, CITGARD 700 Plus, and SynDurance. SynDurance also offers additional fuel economy and improved cold weather lubrication.
