I figure it's like I used to feel that my engine ran smother after getting an oil change. The brain is weird and can't be trusted.
I mean depends how bad you let your oil get.
When I met my wife she mentioned her car had trouble going up hill, I suggested a 5 (new to her for 1 year) year old car should be fine at going up hill.
Turns out she had never heard that you need to change oil, the dipstick showed no oil at all.
Oil change definitely made her car drive smoother ๐
