- For the mission in GTA 1, see Tanker (mission).
The Tanker in GTA 1 is designed as a straight truck with a cab-over design and a tanker load. It is one of the most durable vehicles in the game, being able to withstand a lot of damage. Despite it being a large truck, the Tank is able to drive over it.
In GTA San Andreas, the Tanker appeared with a semi-cab design. It is one of the more popular of the three trucks in San Andreas, being encountered more than any of the others (the Roadtrain and the Linerunner), and is generally designed as a mid-sized semi truck smaller than the Roadtrain but larger than the Linerunner. Finally, this truck, like all the others can attach a trailer in San Andreas, making the experience even better. It looks loosely based on a Mack R series, with elements from Ford L9000 and an International Paystar incorporated into it.
Like the GTA San Andreas rendition, the Tanker in GTA Chinatown Wars is designed as a conventional cab semi-trailer truck, but is only available with a permanently attached tanker trailer.
After an examination of internal files, it is clearly shown that the Tanker in GTA San Andreas is the slowest of all three but it has better acceleration than the Linerunner. In-game gameplay, however, has the truck performing better than the Linerunner, with an unusually better top speed of about 130 km/h (80 mph), as well as superior acceleration and hill climbing power. Its lower body height also makes it less vulnerable to rollovers than the Linerunner.
In Chinatown Wars, the Tanker's long length and large weight makes the vehicle less than suitable for intensive driving, faring poorly in top speed and acceleration, as well as poor cornering (often requiring large turning radius's) and braking. If the trailer is set on fire, it will blow up dramatically, usually killing the player and harming anyone else near the vehicle. Also during a mission the Tanker is shot at whilst the player is driving and starts to leak fuel, this fuel starts to set on fire behind the player and, if they don't pick up enough speed, then the flames will reach the trailer and the truck will explode. This can be renacted outside of the mission also.

- In GTA San Andreas' game files, the Tanker is always named "Petrol".
- In GTA San Andreas, the default radio station in the Tanker is K-DST; in the DS version of GTA Chinatown Wars, it's Prairie Cartel.
- In GTA San Andreas, a glitch in the game is if the Tanker is pulled by a Tractor at full speed the tractor will go at almost the top speed of a race car and the tanker will be flung over the Tractor.
- The Tanker only has one breather.
- On the PS2 Version, the rear of the Tanker seems slightly more detailed than the Linerunner.
- It is believed that in some versions of GTA SA, the Roadtrain comes with either rear axles containing single wheel or double wheels. For example: Comparing Single Wheel to Double Wheels.
- Like all other trucks, in GTA San Andreas, the Tanker will gain handling similar to a train, if given a trailer. It will still blow up, if taken too much damage, but it is nearly unstoppable, by any single vehicle. The truck will only slow down, but will never stop. This is also seen in the Dozer, Dumper, and Rhino.
