How to save at Grease Monkey: the smartest ways

1. Use the national coupon codes. The Grease Monkey coupons page lists the code shown in the offers above for $15 off a Full Service Full Synthetic Oil Change and the code shown in the offers above for $10 off a Full Service Synthetic Blend Oil Change, both redeemable by 10/09/26 at participating locations.
2. Check your local store page too. Individual Grease Monkey centers post their own coupons with their own codes. One store we checked listed coupons for brake pads and rotors, battery replacement, transmission and radiator fluid exchanges, fuel system cleaning and wiper blades.
3. Ask about group discounts. Store pages list discounts for military, first responders, law enforcement, seniors, students and Uber and Lyft drivers at participating locations.
4. Use the free extras. Grease Monkey says oil change customers get a free tire check, fluid top-off, battery test and engine light scan, which can save a separate diagnostic visit.
5. Take advantage of courtesy fluid top-offs. Store pages list a courtesy fluid top-off service.
6. Keep your receipt. The limited warranty on services and products runs three months or 3,000 miles, whichever comes first.
7. Enroll business vehicles. The Grease Monkey fleet program offers consolidated billing and service tracking.

Oil change & service options

Grease Monkey offers full service oil changes with conventional, high mileage, synthetic blend and full synthetic oils. The company says most oil changes are completed in about 15 minutes and include a 16-point inspection. Oil change customers also get a free tire check, fluid top-off, battery test and engine light scan.

Beyond oil changes, Grease Monkey centers work on most makes and models of cars, SUVs and trucks and list services such as brake pads and rotors, battery replacement, cabin and engine air filters, automatic transmission fluid exchange, radiator fluid exchange, fuel system cleaning, wiper blades and headlight lens restoration. Available services and prices vary by location, so check with your local shop.

How Grease Monkey coupons work

Grease Monkey is one of the few oil change chains that prints coupon codes on its site. The national codes, the code shown in the offers above and the code shown in the offers above, are shown on the coupons page with a redeem-by date of 10/09/26 and are available at participating locations. Grease Monkey says coupons can be redeemed online or in store, and you can share a coupon by text or email to have it on your phone.

Local store pages carry their own codes, which can differ from the national ones and from store to store. Some store pages we reviewed still showed older coupons with past expiration dates, so always check the redeem-by date before you visit. If your store shows a larger local offer than the national code, ask the shop which one applies; the official site does not say whether coupons can be combined.

Rewards program & email offers

As of September 2026 we did not find a points-based rewards program on the official Grease Monkey site. The best way to keep saving is to check the national coupons page and your local store page before each visit, and to text or email the coupon to yourself so it is ready at the counter.

Warranties & guarantees

Grease Monkey store pages list a limited warranty covering services and products for three months or 3,000 miles, whichever comes first. Keep your invoice, and ask your local shop for the full warranty terms that apply to your service.

Military, senior, AAA & fleet discounts

Grease Monkey store pages list discounts for military, first responders, law enforcement, seniors, students and Uber and Lyft drivers at participating locations. Amounts are set locally: for example, one store we checked offered 25% off a full service oil change for military, and another listed 10% off for seniors. Bring valid ID and confirm the discount with your local shop. We did not find a AAA discount on the official site.

The Grease Monkey fleet program offers roughly 15-minute oil changes, maintenance tracking and reminders, and flexible payment solutions including consolidated billing. Businesses can enroll through a local location, the online form or fleet support at (800) 822-7706. Fleet pricing is not published online.

Payment & financing options

At least some Grease Monkey locations accept WEX fleet cards, and the fleet program offers consolidated billing and account-based payment. We did not find consumer financing on the official site, so check with your local shop about accepted payment types.

Seasonal deals and rebates

Grease Monkey refreshes its coupon codes with new redeem-by dates, so check back after the current codes expire on 10/09/26. Fall is a good time to use the free battery test and engine light scan that come with an oil change, and to ask about local battery or wiper blade coupons before winter. We did not find mail-in rebates on the official site as of September 2026.
