Looks like it doesn't have a wet clutch. So the oil only lubes the engine.

In that case, you can use any 30 or 40 weight. I would use cheap store brand 15W40. Its cheap, and it works.


17 Chrysler Pacifica Mobil 1 5W30
13 Yamaha XT250 Valv MC 10W40
12 Suzuki S40 Rotella 15W40
10 Acura TSX 2.4 PZL Plat 5W30
06 GMC Sierra Nextgen 10W30

Itís not a shared sump with transmission. The centrifugal clutch is located at the end of the CVT assembly, before the final drive, chain drive, and rear axle.

Use any 15W40, 10W40, or 5W40 with API SL or better ACEA A3/B4 oil. Only use W30 oil if climate is below freezing.

Do the first drain early and donít forget to clean pickup screen. These engines tend to throw a lot of metal flakes on first run.

These are a wet centrifugal clutch drive. Gas-n-go. "Transmission" shares the engine oil. I had one for my kids for a few years, but it was a 110cc model. They come with regular 10w30 and is typically what the manufacturer will recommend, but 15w40 is a better choice. No effect on the clutch.

Chances are thereís some final drive that is in oil, maybe 85W140 EP, 0.1 liter. Send some pics and Iíll tell you what engine it is.

The pickup screen would be in a cover under the engine, openable with a 14mm or 17mm socket.
The oil drain is usually on the left side of the engine, 14mm.

Engine oil capacity is generally less than 1 liter.
