changing engine oil for Ex5

changed engine oil for the Papa's Ex5
cant remember the last time i did. it was black
last time was because the engine couldn't start on cold mornings. lol.

went to a different shop.. Wee Maju, actually any motorbike shop is the same i guess.
just that some mechanics are more toughtful and observant

(like they will rock the bike to get out all the old oil)
and some don't pour in the whole bottle

i asked the lady at the counter which one,
she said Honda? owh that one loh

Honda 4T SL 10W-30 RM 22 0.8L calcium additive prevents clutch slipping reduce engine friction Asked the guy about oil, he said change every 2000km and he recommends Shell, cheap

but i still feel like some of them are longer lasting and better for the engine.
I mean seriously.. calcium to prevent slipping? isn't the oil supposed to make stuff more slippery

Then theres the codes 10W-30
the first number on the left indicates the viscosity (how easy it flows) at a COLD start
so 10 would be before it's heated up... and so 5 would be less thicker than 10 and easier to start on cold mornings... the W stands for windete btw

the second number on the right indicates it at operating temperature, i.e. 30 at 100C
so is it better to get a ticker oil? what's the effects on the engine components? which one is better long term, which one has better fuel economy, which one is smoother, which one is cleaner ..

a 5W-30 will flow better than a 10W-30
a 10W-50 is thicker than a 10W-40

good place to read stuff:

10W-30 is not as fluid, it's thicker.. better for older engines and protects the components thicker got more drag tough.
5W-30 is more fuel efficient, for new engines with small gaps and no need to worry about seal.

and whats the diference between wet cluch and dry?
basically if the clutch uses the engine oil for lubrication, its a wet clutch.
Dry is for when it's separated from the engine

i know some are for automatic scooters

sigh, i dont know if i bought the right one.
well i hope that it stays clean for a long time

i know theres alot of difference when chaning the oil tough, i could feel it last time
it was more smooth.
