About Grease & Gauge

Grease & Gauge was built on a straightforward premise: most automotive maintenance is far more accessible to the average car owner than the industry that profits from their uncertainty wants them to believe. An oil change, a brake pad replacement, a battery swap, a set of spark plugs — these are achievable in a driveway with basic tools, and the money not spent on labor is the most immediate financial return available from any home skills acquisition.

My name is Kevin Marsh. I’m an ASE-certified technician who spent twelve years working in independent and dealership service centers in Ohio and Georgia before transitioning to automotive writing and video production. I’ve performed tens of thousands of oil changes, brake jobs, and diagnostic procedures professionally, and I have strong opinions about the gap between what service advisors routinely recommend and what manufacturer maintenance schedules actually specify. This site is my attempt to put that knowledge on the side of the vehicle owner.
