Aiya vios engine so reliable no matter what oil u put no problem la

Mileage doesn't matter... More important is engine oil consumption.

10 year old je.. go with what stated in owner manual/service manual and come back and ask again after 20 years..

engine consuming EO, I was using bardahl 5w40, that's why want to change to 5w30

No. White smoke is worn pistons. NA almost never can get damaged head gaskets unless the engine was overheated badly from faulty cooking systems. Unlike turbo engines where the gaskets are constantly exposed to very high pressures.

This. Come time just overhaul jer la.

Follow ur manual

Then u shouldn't use a lighter weighted EO. I guess u need to do an overhaul. Have your mechanic check to confirm. Probably top overhaul.

DVVT is all xW30

And Xw is for cold country. Sini takde guna
.

if you car has no issue and no leaking
stick to what u have been using

DO NOT, i repeat DO NOT go for lighter oil just because you wanna save fuel

both ok

That one is light bluish or greyish smoke. Most pple mistaken it for white.

Most engines will hardly have smoke even when it's worn. It's just an increase in EO.

Whichever more expensive

no
some people believe that and it cost them HARD
some people even more stupid, they think vios engine so reliable, they can skip service

and then the catastrophic happen

RTFM?

Have u heard of using grease? Time to learn a thing or two from the russian

Engine rebuild la.
Engine going to keep burning oil doesn’t matter what grade.
The moment it stops burning oil is either you rebuilt it or it’s totally dieded.

The recipe for that oil cocktail is @ 16:30

perodua using it

200k+ mileage, use 5w40 fully synthetic
