[replyingto=kyle401]kyle401[/replyingto]That should work too, but I use 10w40 Castrol GTX. I finally found a place that sells 10w40 motorcycle oil near me (the other places only sell that heavier stuff, like 20w50, etc.) so I'll be switching to that in about 20 miles.

The main difference between car oil & motorcycle oil, is that motorcycle oil doesn't have "Energy Conserving" additives that car oil has, that can mess with Wet-Clutches found in Manual-Transmission Motorcycle. Scooters don't have Wet-Clutches, so it doesn't have that problem. |

10W40 for South Florida
10W30 for New York
0W20 to 5W30 for Alaska and stuff..
15W40 is too heavy for a 50cc. You'll need to up the idle, and the mpg's will go down.
15W40 is good for 150cc's and up, when the engine design is older, and clearances (tolerances) are wider. Modern engines have very small clearances, and use way thinner oil.
Thinner oil allows better cooling, but on the other hand it also doesn't fight engine wear as much.

I use 15w 40 because I ride fairly short distances and I am concerned about engine wear so the thicker oil would be less friction. The cooling issue would not hurt me as I don't really ride far. I just tried 10w40 and my engine felt kinda shakey compared to what I use now, but it was much faster and I noticed an increase in fuel economy so idk lol it is a tough choice. In my honda cub from 1965 I use 15w40 because it does have a wet clutch and it helps with wear.

[replyingto=kyle401]kyle401[/replyingto]i found this link recently: www.calsci.com/motorcycleinfo/Oils1.html#Oilit is long, here is a quote from that link: according to his research 15w-40 are a good choice. personally i don't think it matters much as long as you are changing your oil often. |

Me either
I'm no engineer but I think, judging on how others are also using such a wide variety of oils, it doesnt matter much as long as you change it

Running a motorcycle oil is a good idea for a number of reasons besides the issues with the clutch. First they are designed for air cooled engines. Also having the detergents in your oil is a bad idea as you have no oil filter to pull the impurities out. Use a motorcycle spec oil it will make some difference... 10W40

Hi That's an incorrect statement, as some of the larger cc scoots do indeed use a wet clutch system, the Piaggo BMV 350 is one that comes to mind And theres quite a few others as well Take care and ride safely Yours Hank |

That's an incorrect statement, as some of the larger cc scoots do indeed use a wet clutch system, the Piaggo BMV 350 is one that comes to mind I wasn't aware that they were replacing transmission dry-clutches with wet-clutches. This BV 350 does have wet-clutch, but it does not APPEAR to use the same fluid for both engine and transmission. "And yes, the wet clutch in the BV 350 runs in the hub/gear oil - not in the engine/crankcase oil." modernvespa.com/forum/topic100774Second picture of the thread at another forum shows that the Transmission & Engine Oil are separate. modernvespa.com/forum/topic99624Are there 50cc (or even 150cc) CVT Scoots with Wet-Clutch that use the SAME fluid for both engine & tranny? That is the main issue motorcycle owners have to be aware of. |
