I knew a guy, one of the top 10 richest families in the country, who kept harassing friends for sigarettes. But that Ferrari and dozen other cars were real. Oh well.
I never check my oil but I do bring my cars in for service atleast every year or every 15.000km. Because I let it heat up before putting the foot down, have atmospheric engines (no turbo or supercharger) and Toyota build quality, I have had very little issues with my cars. I don't baby them, they have their RPM range sweeped regularly.
In a well-maintained engine there shouldn't be a reason to check your oil regularly, or else it's of low build quality, not regularly and properly maintained or it's being abused by throttling it hard before the engine and oils have a chance to warm up.
