Q. I hear about TBN and TAN in oil analysis. What do these mean?

October 8, 2014

A. The most basic explanation of these specifications is that TAN means total acid number and TBN mean total base numbers. Technically oriented people will want to give you a textbook definition of these specifications but here is the relevance of these specifications.

Q. What type of grease should I use for my fifth wheel?

September 24, 2014

A. Proper application of grease is equally important as the type of grease. The frequent incorrect method of lubricating a 5th wheel is to simply apply the grease in a ribbon like manner thinking that the engagement of 5th wheel and trailer will spread the grease correctly.

Q. Does Citgo have a high zinc motor oil that would work well in older flat tappet engines?

There is a lot of concern raised over cam damage in older flat tappet gasoline engines when current gas engine oils are used because of the reduction or elimination of zinc. Would using a diesel oil provide the cam protection these older engines are said to require?

July 7, 2014

A. If you are using the older gasoline engine for normal operating conditions, a diesel engine oil type formulation does typically provide higher Zinc levels and the higher viscosity-15W-40 will provide extra oil film in addition to the higher Zinc.

Q. Is one synthetic oil better than the other?

Why does Mobil say they can go 15,000 miles, and Amz-Oil to 25,000 to oil change. while others just say change at recommended intervals according to the book? Also how far can I go with syn oil in our truck fleet, and again, is one oil better than the other?

June 9, 2014

A. Your question regarding the products you have referenced need to be directed to those companies to support their claims. However, there can be a difference in the synthetic composition of engine oils.

Q. I am wondering if you can tell me what the estimated miles per gallon are for a truck using the CITGARD®SynDurance® 5W-40?

I am trying to make a comparison to show the cost savings per truck annually when using this particular product versus a conventional motor oil such as Shell Rotella 15W-40. It is my understanding that with the SynDurance, there is a fuel savings of about 2 to 5% due to reduced engine friction - is that accurate?

May 26, 2014

A. Typically the range has been from 1-3% depending on type of fleet. With current diesel fuel prices that can yield an annual savings of up to $1500 or more annually in fuel savings.

Q. What's the correct way to grease a fifth wheel?

March 31, 2014

A. Good question and an area that is most often neglected or done incorrectly. Many truck 5th wheels are re-lubricated by simply taking the grease dispensing unit and dispensing a ribbon of grease around the 5th wheel plate and often neglecting the 5th wheel jaws which engages the trailer pinion entirely.
