I remember swappin’ out the oil in my ‘17 Nissan Maxima while chillin’ in Toronto last spring. My mechanic swore by 5W-20 synthetic—said it was primo for gas mileage n’ keepin’ everything runnin’ smooth. I’ve been using it since, and it’s clutch. Y’all swear by it, right? Goes without sayin’, always stick to what ya trusted technicians recommend, keeps ya car purrin’. Plus, it’s awesome for cold morning starts, you know!
