On the last day of a Guam trip, refueling, checking your belongings, returning the car, and transferring to the airport or hotel can take longer than expected. TAICO generally requires the vehicle to be returned at the same fuel level as pickup and also requires you to present the gasoline receipt at return. This guide walks through the process from the pre-return check to refueling and vehicle check-in.
The return process at a glance
- Check the return date, time, location, and pickup fuel level on your agreement.
- Refuel with the specified grade on the day of return.
- Confirm that the gauge matches the pickup fuel level.
- Take the fuel receipt and keep it safe.
- Head to the TAICO office without adding unnecessary stops.
- Follow staff instructions for the vehicle, fuel, and return-item check.
Three things to verify first
1. Return time and location
Check the date, time, and location on your reservation confirmation or rental agreement. The TAICO Main Office is at 482 Pale San Vitores Road, Tamuning, Guam 96913-4003. The official location page lists the office as open 24 hours, but that does not mean the contracted return time can be changed at will. Plan around the time on your booking.
2. Fuel level at pickup
TAICO’s current terms require the vehicle to come back with the same gasoline level, while its FAQ describes a full-to-full policy except for some package plans. A full tank is therefore the usual requirement, but any different condition written on your agreement or pickup inspection sheet takes priority.
3. Fuel specified for your vehicle
Check the fuel-door label, in-car information, and rental agreement. TAICO’s terms specify regular unleaded for regular vehicles and premium unleaded for designated Camaro vehicles, but the label on the actual car and staff instructions always come first. Never choose fuel by nozzle color alone.
A convenient pre-return option: Shell Harmon
TAICO recommends Shell stations in Guam. One option before return is Shell Harmon at 1779 Route 16, Harmon. IP&E’s official listing shows it as open 24 hours and offering Shell FuelSave, Shell V-Power Premium, and Shell Diesel. Confirm current hours and pump availability from official information and signs at the station.
Before driving from Shell Harmon to the TAICO Main Office, check live traffic and navigation. Road work and congestion can change the travel time, so do not rely on a fixed estimate.

Shell Harmon is a recommendation, not a mandatory stop. Use the station information provided at pickup and choose a practical return-day location based on where you are, operating hours, traffic, and the fuel your vehicle requires.
Three things to get right when refueling on return day
The basics of self-service refueling—choosing a pump, paying, handling the nozzle—are covered in “Guam Gas Station Guide.” On the return day, focus on these three points.
- Recheck the fuel grade: Read labels such as UNLEADED, REGULAR, PREMIUM, or DIESEL. Ask station staff before lifting a nozzle if anything is unclear.
- Request a fill-up: For inside prepayment, give the pump number, fuel grade, and say “Fill up.” If a foreign-issued card is rejected at the pump, pay inside.
- Stop at the first automatic click: Do not continue topping off after the nozzle first stops automatically; extra fuel can spill or interfere with the vehicle’s vapor system.
Secure the fuel cap and fuel door, and be sure to take the receipt—it is required at return.
Check the gauge and keep the receipt
After refueling, start the engine and confirm that the gauge has returned to the pickup level. For a full-to-full rental, it should be near F, but do not force extra fuel into the tank after the nozzle automatically stops. If the display appears abnormal, do not keep driving without advice; ask station staff or TAICO.
TAICO’s current terms make the gasoline receipt mandatory at return. Check that it shows the return-day date, station, and amount or volume, then place it in your wallet or rental-document holder. A phone photo is useful as a backup record, but it may not replace the original receipt.
Drive as directly as practical to the return office
Long sightseeing detours or another hotel round trip after filling up will consume fuel. Refuel after your activities and shortly before returning the vehicle, then head as directly as practical to TAICO. Do not wait until the last minute, however: traffic, a declined card, pump queues, or a wrong turn can all cause delays.
Set navigation before moving, and do not operate the gauge or phone while driving. Guam uses right-hand traffic. Stay centered in one lane and change lanes only after checking and signaling. If you miss the entrance, do not make a sudden cross-road movement or U-turn; reroute from a safe location.
Returning the car at the TAICO office
- Enter slowly: Follow staff directions and any return-bay markings.
- Secure the vehicle: Shift to Park, apply the parking brake, and turn off the engine. Do not leave the keys and walk away; follow staff instructions.
- Show the fuel level and receipt: Have the return-day gasoline receipt ready for the fuel check.
- Inspect the car together: Compare new scratches, dents, tires, and equipment with the pickup check sheet. Report anything of concern before the check begins.
- Return items and retrieve belongings: Return the keys, documents, and optional equipment, and check every seat, door pocket, and the trunk.
- Confirm completion: Ask whether there is any additional settlement or instruction before transferring to the airport or hotel.
If the tank is short or the wrong fuel was used
You could not restore the required fuel level
When a car is returned below its pickup level, TAICO applies its company fuel schedule and handling charges. This is more expensive than filling the vehicle yourself, so same-day refueling is the normal choice. TAICO’s terms also state that excess fuel is not reimbursed.
You may have selected the wrong fuel
Do not start the engine. Contact station staff and TAICO at +1-671-646-0543 for instructions about moving or towing the vehicle. Driving on your own judgment can spread the wrong fuel through the system and increase damage.
If you may be late or need an extension
Contact TAICO as soon as traffic or a fueling delay makes lateness possible. Under the current terms, a rental extension cannot be completed by phone alone; the renter or credit-card holder must visit the office and make payment. A phone call is notice, not an automatic extension, so follow staff instructions.
If you have a flight, allow time for inspection and settlement, moving luggage, and waiting for transportation. TAICO describes a consolidated shuttle after return to the airport and Tumon-area hotels; timing and waits depend on that day’s operation, so confirm them with the office.
Pre-return checklist
- Return time and office match the rental agreement.
- The correct fuel was added on the return day to the pickup level.
- The fuel cap and fuel door are secure.
- The gasoline receipt is safely stored.
- There are no new dents, scratches, warning lights, or tire concerns.
- Any parking ticket, crash, or contact is ready to be reported.
- Passport, wallet, phone, charger, sunglasses, and the area around child seats have been checked.
- The trunk, glove compartment, door pockets, and under-seat areas are empty.
- There is enough time for the airport or hotel transfer.
Frequently asked questions
Do I have to refuel at Shell Harmon?
No. It is a recommended Shell option. Follow the station guidance given at pickup and choose a practical location based on current position, hours, traffic, and the required fuel.
If the gauge reads F, can I return without a receipt?
No. TAICO’s current terms require a gasoline receipt at return. Be ready to show both the gauge and the receipt.
The office is open 24 hours. Can I return whenever I want?
No. Opening hours and your contracted return time are separate. Keep the time on your confirmation or agreement, and contact TAICO in advance if it must change.
Do I receive a refund for returning early?
TAICO’s current terms state that early returns are not prorated and do not receive a refund.
In summary
A smooth TAICO return depends on checking the contract, adding the correct fuel on the return day, restoring the pickup fuel level, and keeping the gasoline receipt. Identify a convenient station such as Shell Harmon in advance, then leave enough time to reach the TAICO Main Office. If the schedule changes or a fuel problem occurs, contact the office early instead of guessing.
Return and location details were reviewed in September 2026 against the TAICO Terms and Conditions, TAICO FAQ, TAICO location information, and IP&E’s official Shell Harmon listing. The no-topping-off safety guidance follows the U.S. EPA. Follow the current rental agreement, vehicle labels, and on-site staff instructions.
