Marathon Petroleum Cover Letter — Example & Free Generator

A cover letter is rarely strictly required at Marathon Petroleum, but it's often optional-and-recommended — especially for competitive oil & gas roles. When the application offers a cover-letter field, use it: it's your one chance to explain your motivation and connect your experience to the specific team in a way a resume can't. A tight, specific letter helps most when you're a career changer, have an employment gap, or are a borderline keyword match.

Open with the exact role and a one-line hook on why you're a fit for Marathon Petroleum. Follow with one quantified accomplishment that maps to the job's core requirement (think skills like Upstream, Downstream, Drilling). Then a short paragraph on why Marathon Petroleum specifically — tie your motivation to the kind of work the team does, without inventing facts. Close with a confident call to action. Keep it to 4 short paragraphs.

One page, 220–350 words, four short paragraphs. Recruiters skim, so front-load the most relevant accomplishment. Anything longer than a page tends to get skimmed past — concise and specific beats long and generic for a Marathon Petroleum application.

Marathon Petroleum screens resumes with its applicant tracking system (Workday), and the cover letter is typically read by a human recruiter after the resume clears that first parse. So get your resume past Workday first (matching the posting's keywords), then let the cover letter do the persuasion. Run a free ATS check on your resume before you apply.
