[Gjrforce]

 

i use caltex petrol Ron97 with K&N drop in filter most of the time during Royal purple period.

and petronas primax Ron97 with original paper filter during redline.

 

Gentle driving style, 70% city, 30% highway.

RPM1k-2.5k most of the time.

 

all petrol was pump at JB

Nothing out of the ordinary. The RL is indeed good.

Question :- how should we analysis the chart ?

 

What makes a "good" vs "not so good" in this comparison.

 

Newbie asking ... thank you

Not an expert myself.

 

Normally they will list down the average values also, then one can refer from there. Of coz if you have done base result, then you can monitor the changes also. It's also advised to stick to one lab, machiam like dyno like that.

Your redline UOA stated time on oil is 10k km, but time on filter is only 4k km? That mean you did changed the oil filter somewhere before, hence I feel its not the 'true' UOA of a redline with 10k km mileage?

[Genie47]

I won't worry about the aluminium.

 

Water is normal because when you combust petrol there is water. Just depends on how much is excessive indicating to a coolant leak.

 

As suggested, this is not conclusive. Different engine, different take. We must do a series called a trend analysis.
