My truck only suggests I change the oil every 6000 miles or so.
The oil I use is high milage full synthetic that says it's good for 10000 miles, maybe more.
I don't drive much but I change the oil twice a year anyway. Yesterday I did my fall change and the oil still had 61% life left according to the truck. But it was 6 months old.
When I change the oil, the engine runs buttery smooth, but it never lasts. Why is that? What exactly is going on?
Is it all placebo effect? It really feels like it's not. Right after an oil change, the engine feels like it's literally a brand new engine just off the lot. but after a few weeks or so, it goes back to normal. Which is still very good for an engine with 150,000 miles. But not as good as it is JUST after the change.
Does high end oil change quickly once it's in use? Still working for many more months but never working as good as it did the first few weeks? Or is it all in my head and the engine always runs the same?
