june 1st is my annual oil change day for all vehicles i own. last year i switched to gc. i did not install a new oil filter at that time, electing to re use the old filter, which only had 10,000 miles on it at that point. now its back to my yearly oil change day and i am wondering if i should change the oil again or let it go out farther. currently the gc has about 7,000 on it. the oil filter has 17,000. before you all yell at me for not changing the filter, keep in mind HONDA says to change the filter every 2nd oil change, or every other year basically up to a max of 20,000 miles are allowed on the oil filter. i did a blotter test on the gc with a hot motor and the results are fantastic. theres a faint ring forming, but its quite small and it "appears" the gc has alot more life left in it. also the oil isnt even black yet. its a nice milk chocolate brown colour. also i have not needed to add anyu makeup oil. ther oil level is right exactly on the full mark, which is where i put it when i changes the oil last year., so considering that june 1st is my annual oil change day, should i change the oil AND filter? or should i hold out for another 3000 miles and change the oil and filter when my filter finally gets 20,000 on it? looking down the oil filler hole at the valves and cams, they are all in pristeen condition. no sludge or deposits are visible. youre thoughts, please?
