Personally, if the oil has ran long enough to need to be changed, then the filter needs to be changed, also. Think about how much oil is poured out of a filter after removal. If it's not changed, that amount of oil, along with the oil remaining in the engine, will be mixed with the new oil. Instead of changing the oil, you're really doing an exaggerated top-off.The most ideal and easiest is don't change the filter early. Then you have one less filter change in the life of the new engine. There's no need to change oil or filter early if you put strong magnets on the oil filter. See prior post.
Some things can only be seen by cutting open the filter for inspection, e.g. the high amount of carbon deposits in the filter this past OCI. Totally unexpected on an engine only having 10k miles, and this being the third OCI at 5.6k miles having only used AMSOIL Signature Series since 494 miles. Speculation is the carbon is due to switching to 87 octane fuel (Honda Pilot, so designed for it, allegedly), even though using Top Tier gas. I've switched back to premium 91/93 octane, so we'll see. Drove to Wisconsin yesterday and Shell stations can be pretty sparse in the midwest, especially along I-35. Tried to use stations known for having good fuel additive packages, e.g. Shell, Exxon/Mobil, Chevron, BP. But sometimes you have to use the best you can find. So this OCI's non-controlled experiment may be a bust. Still have several thousands of miles to see how it goes.
