Scooters - 50cc => Super 8 => Topic started by: Cardie on November 14, 2010, 06:15:42 PM

Been rooting through the garage today and I found some 10W40 Semi Synthetic Oil. Would this be okay to put in my scooter?
Ive got no idea what the oil thats in the scooter now is, but in the manual it says it should use 15W40.
Does mixing Semi Synthetic and other types of oil cause any sort of damage or is it perfectly safe just to top my ped up with this 10w40 Semi Synth?
Cheers :)

I think I have read on the forum here that folks use the 10w40 with no problems and many folks use synthetic oils. I never liked mixing any fluids. With not knowing what is already in the scoot, If I had the patience, space, ability, etc. I would probably just change the oil out so I would know all was well when I topped up with the same brand/kind later. Definitely go with one that you can find easily.

Is your scoot 2stroke or 4stroke?
-
4 stroke mate

If you found an old can of beans on your shelf, would you just pop the top and start eating them? C'mon, how much money are you saving? Respect what you put in your body AND your scoot.
-
Im not trying to save money or anything like that, at the end of the day oil is oil and if need be all I need to do is top it up, saves all the hassel of doing a full oil change?
Will the engine not have to be flushed out because if I do an oil change with this 10w40 semi and what was in there already was 15w40 normal will this do anything to the oil im putting in?

4 stroke mate
Do not mix different bases (even though nothing drastic would happen).
10W40 synthetic based oil is perfectly fine for your little OEM 15W40 scoot, even better.
If I were you, and if you have 7 dl of oil or more, I would not top up but drain old oil, whatever kind it is, pour in semi and then when the level drops (if it does at all), change oil again.
No purpose fretting over insignificant issues.

Right changed the oil, up to the maximum on the dipstick, wasnt too hard :)
Measured the stuff that came out of the engine and there was about 0.45L when there should of been 0.8L!
I forgot to mention the engine started making a tapping noise a about a week or so ago, so I check the oil and decided to refill as I have.
Tapping noise still seems to be there though? Will it go? Get worse or stay as it is? I dont think its the rod shells (bearings?) or whatever there called, it sounds like its comming from the cam or valves.... maybe im just over reacting? The engine runs fine though been out for a 10 mile drive and all seems well :)
Cheers for the help!

Considering that you have 4 stroke scoot, and if the tapping sound is truly present, most likely the valves are a bit off.
I do not know how many kms does your Super 8 have.
I had valves checked at 20.000 kms on my Agility 125 and they were a bit off: valves should be checked every 6-10.000 kms.
-
its got around 4800 KM, ive asked everyone else and they just say its nothing and its completly normal
-
An ounce of prevention...is worth a pound of cure. This might be one of those times where that old saying applies.
I think you only need feeler gauges to check the clearance of your valves?? If you have some or can get some it wouldn't hurt to give it a look. At least then you would know if it is coming from your valves or the engine. From the way I understand it keeping your valves properly adjusted can prevent future damage or problems.
And if the scoot is used it does not really matter how many km are on it because there's no way of knowing if someone else set them wrong.
And (just my opinion)...it's not "everyone else's" scoot. I'm not saying they're wrong. But I don't want to see you let what someone else "thinks" mess up YOUR wheels. :)
-
Any idea what the gap should be between the valves? Cheers :)
-
Check the general discussion thread and look under the service manual topic posts. Someone may have posted a link to the Super 8 service manual which will tell you the specifications on the valve clearances and have pictures of how to adjust the valves.
For the Agility 50cc it is .04mm.
Valves are easy to check and adjust and they can get out of spec fairly easily. I checked mine at 4,000km and they were indeed off a bit.
-
By saying 'there off' im guessing the rocker is too far off the valve, hence when the rocker pushes on the valve it has to travel further, creating the tapping?
-
Topping off the oil ??? Is your scoot using oil? When you last changed your oil, did you check the level properly? When doing an oil change it doesn't take the whole quart so where is the rest of the oil that wasn't used? Gy6 based engines work well with a valve clearance of 3MM on the intake and 5 on the exhaust.
Are you confident enough to perform a valve adjustment and do you own the proper tools?
2 Things with oil
1) Never mix match oil.
2) Never overfill the crankcase.
It takes 5 minutes to drain the oil and about an average of 4.00 for a quart of oil isnt that worth a piece of mind that all is good?
-
I check the oil quite regularly, it didnt seem to be loosing any but it was at the absaloute minuim, which is when I decided to do the oil change. Its now at the maximum. I probably wont do the valves myself, theres a local bike mechanic near my town which is where everyone I know who has a scooter goes.

I am not sure about 3 mm and 5 mm...

Took it to a garage after college, he fired it up and says it sounds sweet, nothing he can hear outof the ordinary.... Even when he full throttled it for about 10 seconds with no rev limiter though it didnt carry on revving. NEVER though it would rev THAT high, still its fine :) He took it out for a drive and said he cant hear anything and all is good apart from some vibration in the floor panel. He commenting saying its a very nice scooter, apart from the sh**e chinese engine :( ohwell!

Sounds like you have a great mechanic holding the engine at full throttle with no load. I guess he had it in mind "If it isnt bad now I will speed the process up VRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRMMMMMM!!
NEVER do you ever want to rev and engine full throttle with no load!
If I witnessed this I am sorry but he would have gotten a serious ass kicking! I would have said hey where is your car? I want to see how your engine runs at full throttle in neutral..
-
Well its fine? he held it there for a good ten seconds. 50cc Engines will cope with anything you can throw at it, ive gone down 20% hills full throttle and the boss just keeps the speed just under 40 mph, so it will do the same with no load :) I told him it had no rev limiter and his words were 'Yeah I wouldnt do it if I knew it would damage somthing. Plus I knew the lad and the boss of the garage knows me well so they arent going to piss about with somone they know :)
