You do not need a 4WD for an entire Oman trip.
This is one of the most common things travelers misunderstand.
A normal sedan can handle many of the country's main roads. The important part is knowing exactly where a 4WD becomes necessary, useful or simply more comfortable.
Muscat
4WD needed? No.
Muscat's main roads are paved and straightforward. A normal rental car is more than enough for sightseeing around the city.
Muscat to Nizwa
4WD needed? No.
The main route is paved. Nizwa itself is easy to reach in a standard car.
Nizwa and the surrounding interior
4WD needed? Usually no.
Forts, souqs and many villages are accessible by normal road. Check conditions if you plan to leave the main routes.
Jebel Akhdar
4WD needed? Yes.
This is the clearest case.
An appropriate 4WD is required at the mountain checkpoint before the ascent.
The road is paved, but the steep climb and descent are why the requirement exists.
If you are renting a sedan for the rest of your trip, you can still arrange a local 4WD or book a guided day such as Nizwa & Jebel Akhdar.
Jebel Shams
4WD needed? Not formally required, but often useful.
Unlike Jebel Akhdar, there is no equivalent 4WD checkpoint.
However, parts of the route can be rougher or unpaved depending on current conditions.
A normal car may manage the drive, but a 4WD can make it more comfortable.
Sharqiya Sands
4WD needed? Yes, if you are driving into the dunes.
But this is important: having a 4WD does not mean you know how to drive on sand.
If you have no desert-driving experience, arrange a camp transfer or go with someone who knows the terrain.
A Night in the Sharqiya Sands removes that uncertainty.
Wadi Bani Khalid
4WD needed? No for the standard visitor route.
The main access is straightforward.
Wadi Shab
4WD needed? No.
The standard road access works with a normal car.
The adventure begins after you park and start walking.
Wadi Al Arbaeen
4WD needed? Often recommended.
Road conditions can be rougher than the main coastal highway, and a higher-clearance vehicle can make the day easier.
Check current conditions before going independently.
Muscat to Sur
4WD needed? No.
The main coastal route is paved and works well with a standard rental car.
Sur and Ras Al Jinz
4WD needed? No for the standard route.
Normal roads connect the main visitor areas.
Daymaniyat Islands
4WD needed? No.
You are going by boat, not by road.
Musandam
4WD needed? Not for Khasab itself, but useful for mountain routes such as Jebel Harim and Khawr Najd.
White Dunes of Khaluf
4WD needed? Yes for remote access and sand driving.
This is not where I would recommend experimenting without local knowledge.
Should you rent a 4WD for your entire trip?
Only if several parts of your itinerary genuinely require one.
If most of your journey is Muscat, Nizwa, Sur and the main coast, you may be paying more than necessary.
A practical approach
Use a normal rental car for easy paved routes.
Book a guide, local transfer or temporary 4WD for the days where it actually adds value.
My advice
Choose the vehicle after you build the route, not before.
Oman rewards flexibility, but the best car is the one suited to the exact road in front of you.
