The recommended service interval in the book is every 6000km.

Workshop here been living in the old kapzai era asking you to do unnecessary oil change every 1000km ~ 2000km. This is for bike with wet gearbox that uses the same lube for engine and gearbox.

Your scooter is dry gearbox.

However, by around 3000-4000km your engine will feel a bit heavy but does not mean the oil is bad. Changing oil around this mark will "lighten" up the engine.

No need fully synthetic to go 6000km. It's not specified in the booklet.

Recommend you to do unnecessary servicing = more revenue.

Wait till you show them you can use normal car's engine oil for your scooter.

Also a big scooter group using diesel engine lube for their scooter and swear by it. Those scooters reportedly done over 50,000km servicing only on Shell Rimula X.

Is there anything wrong? No, not at all. Only those living in gua tempurung will feel it's wrong.

Modern lube is usable for both petrol and diesel engine (higher heat, more exhaust particle to "hold" in the lube). Look for API SN/CF, one example.

I can't find it anywhere on owner's manual.

Some cars do have the word "synthetic" baked into their owners manual, but not for Vario / ADV160 / ADV350.

Same like I mentioned above.

10W-30 is viscosity rating i.e. how "thick" (in layman term) is the oil.

It's nothing about mineral or synthetic.

Not true. Handbook is the one to be followed on warranty related matter.

My first 1000km service I asked for mineral oil, BigWing SA say huh, this one only 1000km need to service again.

I said just use lah, show them handbook, they kept quiet but still say next service is 2000km, with a sticker which I throw away.

1.5 liter lube with oil filter (ADV350).

Current mileage 3,500km, check oil on dip stick, still good. Engine does not feel heavy.

Now I wait for some ktards to tag me as can't afford synthetic and can't afford to maintain big bike.

There are both mineral and synthetic version of Honda MB lube 10W-30.

Got to be the Impian X you went to.

The Impian X I went had both to offer. That's when I was running my ADV150 / AV160.
