i found interesting post here, let's discuss as i have been in auto industry for more than 10 years. it's interesting that nowadays engine oil can last for more than 20,000km easily. anyway the SC or general workshop still recommending the old ways of OCI such as Mineral for 5K, Semi 8K and Fully 10K.

and our Malaysia market is so fussed/obsessed about the word SEMI and FULLY. actually is a same oil!..the oil marketer making tonnes of monies by selling SEMI and FULLY labelled oils.

i only changed my engine oil every 20K or 6 months without blotter test as for the past 10 years. transmission oil even longer...... last change was 3 years ago.

Malaysia driving environment relatively clean. so 20K no problems at all with FILTON RM 5.00 oil filter.

i prefer stick to SL grade as mentioned at 1st post due to as API SL grade tends to have higher ZDDP and calcium comparing to SM or SN grade..

opted for higher OCI, go for SL grade. wont be wrong. We have no air pollution regulations here, so guess what, some of the cars are even without catalytic converter. go for it !

to have higher OCI, the base oil composition is pretty damn important rather than additives itself.
