I bring 0W30 and the filter for their use. They say OW30 will be easier to get dirty for the engine and need to change in a short time. How true it is? DCH also receive Waste Disposal Fee $65.

short time......how short?!

from my understand......full synthetic engine oil can run for at least 10,000km still in good condition.

And some better grade engine can last up to 50,000km.......shorter time = 50% of 10,000km or 10% of 10,000km? 日本仔用0w20又行HWY, 你唔會覺得佢地個個月去换油掛

In fact, dirt in the engine oil is only showing the engine oil is doing the job of cleaning, which does not imply the condition of the engine oil. So, even the oil is dark, but it may still doing a good jobs of cooling, cleaning and lubricating.

果D著哂制服嘅師父話佢地用0W40,30會快D換楬油！我就覺得佢地唔想我自備。無錢賺嘛！最後72元找數離開，臨走前sales千叮萬噣叫我下次唔好帶嘢嚟換！司馬昭之心！其實下次再去大昌定找車房換油好呢？
