CJ-4 Engine Oil
Posted by Justin from Marietta, GA, US on May 29, 2008
Can the new API CJ-4 engine oil, designed for ‘07 complaint engines, be used in older engine models? What benefit can the new CJ-4 oil blend provide for older engines? Longer drain intervals? More wear protection?
The API CJ4 engine oils are the most robust engine oils that the heavy duty market has ever seen, they have been boosted in many ways to ensure that they exceed the performance of previous lubricants, particularly in the areas of soot handling, wear and oil consumption. They are fully compatible with engines of all generations. Using a CJ-4 oil in a pre 2007 engine will give the benefits of reduced wear, oil consumption, deposit formation, and could certainly allow extended drain to be reached. However extended drain should only be carried out in conjunction with a used oil analysis programme (such as castrolLab Check) to ensure that the lubricant is not being stretched too far.

motor oil refining system
Posted by joe from wantagh, NY, CA on April 22, 2008
do you know of the ops-1 oil refining system i would like to try it out.
The OPS oil filtration system is one of many extended life filters that are being marketed on the basis of oil drain extension, BEWARE!! Oil drain intervals are based upon a number of criteria, can be categorized into 3
* impurities,
* depletion of additives,
* degradation of base oil.
The OPS system, while effective at filtering some impurities (although not effective on all soot), will do nothing towards the other areas. The additives that are in a high quality engine oil are designed to be sacrificial, in other words to deplete over time, once depleted the oil will rapidly cause wear and engine failure. Base oil degradation is accelerated by additive depletion, and again will cause oil thickening, and lack of lubricity.
Dealing with a 1-2 gallon spill of hydraulic fluid onto a residential street.
Posted by Amber from Cody, WY, US on May 21, 2008
Our neighborhood recently received a delivery of sod, distributed by a small lift tractor whose hydraulics failed and spilled approx. one or two gallons of fluid onto the street. People in the neighborhood immediately flooded the area with Dawn dish detergent and water, washing the stuff down the gutter and into a deep drainage pit. A couple of questions come to mind; how toxic is the soil where the mixture has seeped down into the rocky/clay blend soil in regards to pets and humans using that area and, if it is indeed really nasty, how long do we avoid that area? Also, is there anything else we can do to alleviate the situation? Thanks!
An oil spil of any tyype is never good, and flushing it into the water system also not ideal. The contractor who's equipment failed should have carried out a complete clean up which would have been to clean up excess, then clean with a strong detergent and plenty of water, avoiding any ingress into the water system.
However, the residue that you have is there, without knowing what type of oil is used it is dificult to be accurate, but assuming that the oil is a normal hydraulic fluid the area will not be dangerously toxic. Most hydraulic oils are biodegradable to some extent, and the residue will be fully degraded within 90 days.
Cleaning Hydralic oil from clothing
Posted by Errol from Mandan, ND, US on May 19, 2008
Whats the best method to clean hydraulic oil from clothes? Thank You, Errol Thvedt, Mandan,ND stset@btinet.net
the best way is to take to a dry cleaners where they have access to very strong detergents capable of removing oily stains
Lifespan of Aw-32 Hyd. Oil
Posted by Brad from Belvidere, NC, US on April 23, 2008
How long can AW-32 hydraulic oil last in a stationary compactor?
Manuafacturer states 1 year but outside sources say indefinitely based on color, texture and consistency. Say to run a couple filters on it.
A hydraulic oil has a number of purposes, it activates the machinery / rams etc, it cools, it cleans and it lubricates. Any oil is made up of certain performance boosting additives which help the fluid carry out these tasks. now to answer how long it will last, the fluid will be exposed to impurities, like dirt and water, these can be removed with good filtration and separation, however the thermal and lubrication aspects will not be affected by filtration. Unless you carry out an analysis of the condition of the fluid then always follow the OEM interval.
