QUOTE(zeng @ Feb 9 2017, 09:33 PM) I mean taking pictures 48 hours or thereabout AFTER depositing the above Blotter Spots of yours ...... as is my picture in post #1. There is usually minor variations against those taken say, 2 hours after depositing the Blotter BST.  Curious..Did you change the oil filter in between the oil changes? If yes on what mileage?

QUOTE(zeng @ Feb 10 2017, 08:13 PM) No. Filter is of same mileage as this oil, now approaching 12600 km. Is there something to be wary of ? Hmmm...In read somewhere it says that it is better to change the filter every 5k-8k eventhough the oil didn't change. Then just too up the oil. Forgotten where and not sure how true is that though. All i know is original oil filter is the best if compared to other aftermarket brands. Seen the video and filter elements inside in YouTube.

QUOTE(zeng @ Feb 10 2017, 09:20 PM) Agree with you that the rule of thumb was filter change in every 2 oil changes totaling 10,000 km. But, from what I read at bobistheoilguy.com the Americans are habitually changing oil filter at more than 10,000 miles (not km)........ granted our filters used here might differ from theirs. From this Blotter Spot Tests picture above at 12,238 km mileage (and other pictures with me as well) , I'm of the opinion that this RM12 filter is holding up well so far ...... though it's always to safer to change earlier or as recommended by OEM etc. I think it highly depends on our driving conditions. For daily stop go traffic as in Penang,Kl, Johor..I think it is better to change the filter earlier. Engines are more strained in these conditions, furthermore the air will be more dusty. I do not know how well foreign particles are suspended in the oil, so no comment on the blotter spot test for this dirt aspect. . Best is take out the filter and cut it open to check the filter elements.
