AS your Fleet Master is API(American Petroleum Institute) CH-4 Specifiication but i have checked that with Toyota Indus and they have below feedback to me.
Mail i sent to Toyota Indus
Dear Toyota Indus,
I have checked from you website at below link
INDUS MOTOR COMPANY LTD - Imported Vehicle -
About the ENgine Oil and checked that Diesel Engine Oil is sold with API
CF-4 Specificiation while in 2004 API already declared API-CF-4 as
Obsoleted Standard then why not you upgrade to CH-4 which is backward
compatible, and same is true for API-CD Specification Diesel Engine Oil
which is long time ago have been Obsoleted and still you are selling as
new.
Please check and reply as i have Toyota made ride and usually get my
Maintenance from Toyota 3S but here its shocking for me.
Regards
</PRE>

Dear Mr. ,
With reference to your query regarding API recommendation of Toyota Diesel
engine oil as shown on our web page.
Please note the following points:
1- We Indus Motor Co. Ltd. market Toyota Genuine Oils for Toyota vehicles.
No doubt that API CD & CF-4 is obselete, but
these grades are still in consumption in Pakistan specially in old
vehicles engines where CH-4 or superior oil is not recommended.
We are marketing these grades due to the market requirement of API CD &
CF-4 grades.
2- Toyota Genuine motor oil is formulated by Toyota Motor Corporation.
Toyota recommends the best API grade engine oil to use.
See your vehicle owner's manual for the best API recommended by Toyota
for your Vehicle.
3- CH-4 diesel engine oil exceeds the requirements of CD & CF-4 is also
obselete in year 2002 & the latest API grade is CI-4 Plus.
* note that no above grade is discontinued from API service category.
Grades obselete due to newer API service category.
4- The API grading requirements depends on the engine type / technology &
OEM recommends it according to the requirement of
engine. CH-4 & CI-4 is usually required in modern technology engines
or heavy duty diesel engines.
We are marketing all API service category grades that Toyota recommends in
Pakistan & required from local market of Toyota vehicles.
If you have any other query please do let us know.
