Today I have a Vespa GTS 300 Super in the shop for an oil change. Regular oil changes are the best thing you can do for your Vespa, it's quickest, "easiest", most affordable way to ensure you get high mileage out of your scooter.
Here's a list of the items I use in order to get the job done efficiently.
24mm Offset Wrench,
Channel Lock Pliers,
Needle Nose Pliers,
5mm Allen Wrench.
You will also need a Vespa Oil Filter #82635R and up to 1300cc of 5w40 FULL SYNTHETIC Motor Oil.
***I understand that 99.999% of you reading this won't have access to a motorcycle lift, so you'll want to enlist the help of a friend to hold the bike steady as oil changes are best done with the scooter OFF the center-stand. If you don't have any helpful friends, you can do the oil change with the scooter on the center-stand, but it gets very, very messy. Also, you'll notice in the pics I removed the exhaust, this is not necessary. I removed the exhaust only to take clearer photos.
OK, let's get started. Ride your scooter around for 5 to 10 minutes to get the oil nice and hot. Hot oil will pour out faster, carrying more contaminants out with it in the draining process.
All that's left to do now is the clean up, spray the underside of the motor with Brake Clean to remove any oil left from draining, then blow with compressed air or wipe with a rag. Make sure the dipstick is tight, start the scooter and let it idle. Make sure the RED low oil pressure light on the dash goes off. After running the bike for a minute or two. Switch it off and check for leaks. Wait a few minutes then check to see how the oil level reads on the dipstick. REMEMBER! You have to completely thread the dipstick all the way home to get an accurate reading. Don't just dab it! Have a quick peek underneath to check for leaks. All good? Now, go for a ride!
