I just changed oil after 7000 miles in my 4runner after struggling with oil drain plug, it was pitch black but I couldn't remove the oil filter housing so I drained the oil and put Pennzoil platinum 0W-20 ( bought through rebate) leaving the old filter. My question is will it be okay if I change the oil filter later, I planning to change the old filter with a wix filter next week by taking it to my mechanic during my day off. The usual quick lube place I go over torqued everything, they used supertech oil last time. I doubt they put quality filter. Does the old oil in my old filter spoil my new oil?
Lesson learned : changing oil in a 5th gen 4runner by yourself is not worth it.
