Dumb question

Avid leaser turned buyer. Due to leasing, I always did my oil changes at the dealership I leased from. Now that I’m an owner, how *bad* is it, to get my oil changes done at places like valvoline, delta sonic, etc?

I’d love for to keep this car in excellent condition by all means necessary, but wouldn’t mind saving $75 every oil change, either 😅 thanks!
