viscosity ranges
Posted by Steve on March 21, 2006
When CJ-4 oils hit the streets, will you be offering grades other than 15W40? for example 10W30, 5W30 or 5W40 If not initially, when?
One of the things we are keen to ensure is that we offer products which offer genuine benefits for the consumer, rather than just change for change sake. Initially we will only launch 15W40 CJ4 products as these are the primary recommendation for North American OEM's. However we are looking at offering some further variants in the future.
Use of new oil technology
Posted on March 14, 2006
I am confused about where I can use the new oils?
The new API CJ4 lubricants are fully backward compatible, and can be used on either 2007 specification engines or older engines. Any non CI4, CH4 or even CF4 lubricant should not be used on 2007 engines as it will affect the life of the after treatment.
Reduced performance?
Posted on March 14, 2006
Will these new lubricants result in reduced performance or oil
drains?
The API CJ4 lubricants have been formulated and tested to show that performance is of the same level as existing (API CI4+) lubricants, therefore it is not expected that drains will have to be reduced.
Difference in performance of new lubricants?
Posted on March 14, 2006
How do these new lubricants differ from existing lubricants, and can I expect the same level of performance?
These lubricants differ significantly from current lubricants (API CI4+) as they have chemical and physical limits to the formulation. The result of this is that the performance boosting additives within the lubricant need to be modified to ensure that they will not damage the after treatment. These new lubricants employ novel components to ensure that performance is not compromised by these changes, and that performance is maintained at the levels of today.
2007 Technologies affect lubricants?
Posted by Steve on March 14, 2006
I read a lot about the new engine technologies required for 2007, will these changes affect the lubricant?
On October 15th 2006, engine lubricants that meet the new oil specification API CJ4 will be available. These new lubricants will be designed to be compatible with the exhaust after treatment that is being adopted by the engine manufacturers to meet 2007 emissions.
