Plenty on here recommend certain oils to clean up sludge and varnish. So if fresh oil can remove some varnish and sludge, what's so special about a few molecules thick additive layer?
I'm not a chemist, but this phenomenon should be easy to grasp, provided one approaches it with logic as well, instead of ridicule
I ask questions. If a new idea doesn't jive with how I see the world, I ask questions. If the new idea is shown to be true, then I adjust my view of the world accordingly. This is how I live. This is how I learn. This is how I grow.
But you gotta have an inquiring mind, have a thirst for the truth, and be humble enough to admit that you don't know everything.
I try to live by all these ideas.
Jim Allen made his point. However, like he kinda alluded to, there are SO MANY factors to be considered when pondering "am I causing more wear to my engine by changing the oil early."
One extreme example is in my Honda Ruckus scooter. I know, it's a scooter. I know, it's only 50cc. But from the hundreds and hundreds of people that I have contact with online who own these scooters, it is IMPOSSIBLE for me to have 17k miles on my scooter and haven't had to change a crank bearing or even adjust the valves....the valves are still perfectly in spec.
Out of those 17k miles, I've done AT LEAST 30 oil changes. I've never gone past 600 miles!! This engine spins between 9k-10.5k over 90% of it's life.
My point being in all this: Have I caused extra wear in my little Honda engine by changing the oil too often? No way. What I did prevent was the oil from shearing out of grade (causing increased wear) and prevent excessive fuel dilution (causing increased wear). The "extra wear" I caused by pouring in new/fresh oil almost constantly is TINY compared to the extra wear that would have been caused by running the oil out to 2000-3000 miles like most people do.
I guess I need to read the paper that Jim Allen alludes to....to make sure the increased "wear" these guys are seeing with fresh oil can't be contributed to the fresh detergents cleaning up sloughed off metals embedded in varnish/varnish that the new oil is removing. This was alluded to by early by demarpaint.
