Hi guys, just realised such thread. And first time posting. I know it might not be useful to get a sample at 3k but I want to practise and get it right.
Attached, Honda City 2011, odo at 100km, 3k since oil change, this is the first time I used Honda fully synthetic oil, previously always on their semi synthetic. Previously on caltex 95. Now changed to petronas 97 starting from Nov 2017 since can get petrol card from lazada on discount.
This pic taken after 60 hours sample is taken. Sample take around 5 hours after short ride to local pasar.
Any feedback or more info I can provide?
By the way, how would we detect if its fake oil? Any tell sign?
https://forum.lowyat.net/uploads/attach-47/...-1524619657.jpgThis Honda fully synthetic at 3000 km has some sign of centre ring (though elongated in shape due to handling or slanting placements after drops on paper), and to monitor closely for extending OCI.
It's outermost rings indicates presence of fuel, possibly caused by sampling while cold, it could also mean petrol fuel gets into engine oil during engine operation.
There is a chance that an Euro 2 RON 97 of 50 ppm sulphur may slow down engine oil contamination from sulphur acidification.
No,blotter spot test cannot differentiate if an engine oil is fake or not. It may indicate engine oil conditions at relevant km reading, which in your case I personally am not 'impressed' with this Honda fullsyn for now, in relation to the Aisin 5W30 above.
But we need comparisons of blotter spot at higher mileage, besides comparing blotter of other engine oil types (as listed in post #1) in similar engine under similar driving conditions.
Hope it helps.
Edit:Viscosity grades, xW20 ??
