Oil Disposal
Posted by Steve on June 14, 2006
Hello, can you tell me which places accept used oil? Or how to dispose of it properly?
Disposal of oil is a sensitive issue now a days, the best way of disposal depends upon the quantity of oil you want to get rid of, if you have a large and regular quantity of oil to be removed, then get in touch with your local castrol distributor who will be able to help,however if it is a small quantity from domestic use, then most quick lubs, will be happy to let you pour your gallon of oil into their waste tanks.

1 how is ultra low sulfur fuel going to effect oil change intervals on pre egr engines?
2 my 03 aset mack engines are calling for a 300 hour oil change interval, at 300 hours the oil is very thick and tar like. have you done any testing on this type engine,and what change interval do you recomend?
two very good topical questions. ULSD which is due to be introduced by the fall of this year, will reduce the sulfur in the fuel from 500 ppm (nominal) to 15ppm. This reduction in sulfur will make life easier for the engine, as will reduce the amount of soot, and corrosive deposits in the oil. However the oil drains because of this change will not reduce.
We have a large amount of experience on the Mack ASET engine, and the 300 hour drain interval you are using is on the high side, dependant on the duty cycle you are using, may be too high.
The very thick nature of the oil suggests that you are experiencing high soot loadings in the oil after this period this could cause longer term problems with wear and sludge build up.
300 hours and beyond is easily achievable, but i would recommend as high performing oil such as Hypuron S, and careful oil analysis to see where you are. Alternatively reduce the oil drains to 200 hours.

would it be safe to use synthitic oil in an older engine with over 100,000 miles on it
Synthetic oils have many benefits over mineral based oils, including improved thermal capabilities, improved deposit control, and wear protection. These sort of benefits are suitable for all engines both new and old (>100,000miles)
bearings and grease
Posted by Bob on June 7, 2006
I am taking a test and the question is: “Either over- or underlubrication can cause bearings to overheat.” True or False?
The contest is that of pumps of sewer treatment plants. I am a professional engineer, with the EPA of Atlanta, in the water program, and they have paid forty-five (45) Dollars for me to take this course, since I review reports from wastewater treatment plants, almost daily. In fact, I have examined more than 120 reports, since February 19 of this year.-
Well, anyway, any response would be appreciated.
Over lubrication can be as bad for bearings as under lubrication, however the type of failure can be quite different. With under lubrication, the consequences are obvious with debris, and over heating being major problems which will lead to extreme short life.
However with over lubrication problems such as cavitation and erosion can cause damage to bearing surfaces which can also be disastrous for bearings.
