What oil do you use for your GTS?

And a stupid question, cause I'm no handy guy, how do you fill the oil?

Be prepared for a few rolled eyes. An "oil thread" will lead to many "here we go agains". Piaggio recommends a full synthetic 5W40 oil. There are many of them out there including Shell Rotella, Castroil, and Motul (my favorite). Just match the specs in your owners manual and all will be well. Now, if you don't know "how to fill" the crankcase of your bike, I'd suggest a little training on how to check the oil level and having oil changes done by a dealer until you become a bit more "scooter savvy".

5w40 Motul is exactly what I got from my local shop about 5 min ago.

Rolled eyes expected. Just want to make sure I'm doing it right.

It's not due for a service. I just ride it hard due to commute and want to make sure I don't so something stupid.

Just need to fill it back up.

We've had that during long full-throttle journeys (which eat oil) - just fill up a bit to get it above MIN and all is well.

Roninberumen,
No rolled eyes here as I firmly believe there is no such thing as a stupid question- We all had to start somewhere remember.
However, before you post any further questions on this, please, please, please read these manuals first

1. Start with the owners manual. Save it, study it, own it: http://www.scootermanuals.us/manuals/Vespa/GTS300%20Super/GTS300%20Super%20Owners%20Manual.pdf

2. When you have digested the owners manual and are starting to feel adventurous, here is the workshop manual http://www.scootermanuals.us/manuals/Vespa/GTS300%20Super/GTS300%20Super%20Workshop%20Manual.pdf

Enjoy

There is a scooterwest video on YouTube showing how to change the oil in a GTS. Do a YouTube search. All your questions will be answered.

Coming from the guy that posted this...

"I only replaced the stock shocks because the genral opinion of MV members seem to refer to stock shocks as junk. I really don't know what I expected with the new equipment, but I thought it would be quite noticeable. It wasn't, and isn't. I'm kind of sorry I apparently wasted my money.
Incidentally, I did also install Jettin bushings to replace the original rubber ones.
Oh well, live and learn."

Thumb happy? FFS it's just an opinion from a rider with more experiences than a dozen others. Relax. Thumbs up Dick, for managing your way around the computer. You're the only 91 year old I know still riding and posting. I cracked up on reading both posts.

This is a perfectly legitimate question. On a car engine, there is one hole for the dipstick, and another one for the oil fill. On small engines, the dipstick is attached to the oil fill cap. The answer is yes, you use the same hole, and you tighten the oil fill cap all the way down and then remove it to check the oil level on a Vespa. It is different for some other small engines.

Cheers and good luck,
Bob

When in doubt, use the same hole. Sound advice.

I know it was the dumbest question but who wants to ruin their bike? I'll take a little shame and give the next guy a break.

No shame to be had. But I have to admit the response made me laugh. There are absolutely NO social filters on here Razz emoticon

Sorry, late checking this thread. Yes, as the answers above, the oil goes in the same hole.

Do use a funnel (or some sort of tube) though, don't dribble oil in without one, as the transmission cover 'covers up' the surround of the sump oil filler/dipstick hole, and there is a slight gap. If significant quantities of oil get in that gap (unlikely, but possible, I've seen it before) then the belt etc could be compromised.

Interesting !! I was not aware of this before, that excess oil can make it's way into the transmission, and have to admit I have not always used a funnel. I will in future. Learning all the time- thanks Jim

I use Rotella. Available at WalMarts. No such thing as a dumb question. Glad you caught it because had you not it would of been a costly lesson. Now get back out there and ride it like you stole it. Laughing emoticon

This is really IMPORTANT advice for someone new to Vespas. There is a tendency for inexperienced riders/mechanics to overfill the crankcase oil. Definitely a bad thing which will cause blow-by of oil into the air filter.
