Hi Gamb1t,
Base on their explanation as quote below:
"BG Drive Line Service
Operation Description:
One of our trained technicians will use state-of-the-art equipment to: quickly and
effectively remove old, worn out lubricants from manual transmissions, front and rear
differentials, transaxles, and transfer cases; install BG gear oil or additive package that is
required for the vehicle application; and road test your vehicle.
Significance:
Heat, moisture, extreme pressure and heavy load cause gear oils to breakdown or
become contaminated. Contaminated gear oils lead to lubrication failure and worn gears.
Worn gears = Major repair costs. A BG Drive Line Service performed at the appropriate
mileage intervals will provide your vehicle with thermal stability of the gear oil,
smoother gear shifting, quieter operation, improved fuel efficiency, extended component
life, and optimum drive line efficiency. Service recommended at OEM's requirements;
whenever vehicle has been driven through water; or 30,000 miles/50,000 km.
Advantage:
Benefits of the BG Drive Line Service include: thermal stability and long life of
lubricants, optimum drive line efficiency, improved seal performance, protection against
wear, pitting and corrosion, and extended component life."

Yeah,basically lubricant change.
On a 65K Miles car,is it recommended to do the Fuel Injection and 4x4 service?I have seen a FCA Euro Video with this,I haven't check DIY for the 4 x4 service.
I've been working from home for nearly 2 years so the car is less used and just sitting in garage tap with a Genius NOCO 26000 Tricle Charger.
