My sister has been going to Marshalls for years and asked me about a maintenance issue. I was looking over my sisters receipts and noticed Marshalls Service Center has been recommending and doing 3000 mile oil changes when current day oils/vehicles only need it at most every 5000 miles. The manufacturer of this vehicle calls for changes at 7500. This is very dishonest of Marshalls to mislead customers for their own profit.
Also, on the receipts, Marshalls is "recommending" additional routine maintenance services that according to the manufacturers schedule, aren't due for 10's of thousands of miles more! The vehicle is used under normal conditions, not a severe service condition like towing. And I've checked these fluids they "recommend" having changed and they are fine.
