Running 10w40 mobile 1 4T synthetic now. Live in Florida heat. Will 10w30 synthetic work just as well or do I need the 40 weight for the heat?

Hi
Either weight would be fine, with my 4 t scoots I use a lighter weight in the colder months and heavier warmer months
Of more importance is to use quality oil and do regularly scheduled oil changes. I change engine oil every 250 to 500 miles gear oil every 750 to 1,000
Take care and ride safely my friend
Yours Hank

You can use both, but the engine might be vibrating a bit more with 10W30. Now that we're entering summer, 10W40 would be your best stock oil.
If you have 10W30, buy a bottle of 15W40, and mix them in a 66/33 ratio (2/3 10W30, 1/3 15W40), to give you the good of both worlds.

Hello, I say both also. But since we in the southern heat, I would stay with heavier weight. If your doing a lot of hard ridding. I would use 10w50 or 15w50. My two cent's. Dave  |

If your scooter is a 50cc I would not get anything heavier than 15W40 or 10W50. It'd sap too much power from the engine and sometimes result in hard starts.
I personally think 10W30 or 10W40 is better oil than 10W50.
15W40 to 10W50 oil would be only good if you're running in desert heat, or have an old, worn engine.

The temp differences between hot outside temps, and cold temps, are only minimal in an engine block. Thicker oils are used on older engines, to get better compression on piston rings that don't seal well anymore, etc...

That's more for impurities, not because the oil is wearing out. The smaller the engine size, the less the efficiency, the more impurities. |

If the engine calls for the oil film thickness provided by a 10W40 oil then it needs a 10W40 oil to keep the bearings and the journal seperated far enough that they don't bottom out. Go thinner and over time you will have scuffed bearings. Synthetic can be already a bit thin so you may at times need to go thicker in the hotter climates not thinner.
10W30 way be ok if you ride where it is below freezing most of the year as the engine especially on short runs may never reach a normal temperature and when run at higher revs could snap the oil pump drive if the oil hasn't warmed up enough to let a 10W40 or 15W40 flow freely.
Synthetic in an engine without a filter in hot climates can become more of a cutting oil if run too long with all the suspended impurities which will be made worse when running oil thinner then specified for the ambient temps.
