Zeng...... this is Aisin fully synthetic (PAO+Ester) 5w-40 API SN.
Done 12k kms. Used on Elantra 2.0 NA (G4GC). Pic shows 48hrs blot, sample taken hot.
Huuh ........ that's no joke. It's hell lot of clean and transparent, not much of dark coloured contaminants such as soot, dirt, combustion byproducts etc.
It's like my 5000 km oil blotter above.
This oil is powderful, that's for sure.
At the same time , this Hyundai engine is very clean and in tip top condition. How long mileage is this engine, btw?
Any intention of prolonging oil change of existing sump oil ?
Edit: Heck , this is 194k km engine. Two things here:
a) there is no doubt about the capability of this engine oil(Aisin fully synthetic (PAO+Ester) 5w-40 API SN), and
b) this Hyundai engine is hell lot of a clean at 194K km indicating high quality of this engine design and manufacturing , maybe helped by your driving habit and maintenance regime.
Japanese OEMs better buck up, IMHO.
Edit 1:only very faint shape of centre zone, and is fully transparent not opaque.
Edit 2:Sorry, I think this 12,000 km Aisin 5W40 oil blotter is obviously better than my 5000 km Total Quartz 7000 Energy 10W40 A3B4 oil blotter.
