Synpower is the best Valvoline oil.

My honda no oil consumption problem..... 10k interval serbis.

my cars all 10k km service interval
all full synthetic, using 5w30 and 0W20

I use this 0W20

if your car manual recommend 0-w20, then use the recommended oil spec

apa heat control n mileage high? low boost 1.5 only ma....
just dun keep boosting when 5 mins from reaching destination, let engine oil circulate to cool the turbo before shutting the car down.

you only change if makan oil and put in thicker 5-w30.
some ask you cause they might have not got the oil in stock or they buy that in bulk thus cheaper and earn more from it

mine will be hitting 300k sometime next year

yes...

unlike Balance's 260hp
I got only 200hp, probably a lot less as almost 20 years old
no oil consumption. Castrol Edge 5W30 engine oil and expensive petrol

what year? maybe go with 5W30 if burning engine oil

You will also need API SN/SP type of oil if later models, I use cheaper SL oil as my car is older.

newer K24W requirement is 0W20 already due to tighter tolerance
but old already can move to thicker oil if start to consume oil

I reckon the problem is US service intervals are based on the 7,500-mile, that is roughly 12k km

same oil pan cannot la long run unless the car mostly all freeway. US lot of cars clock up the mileage due to heavy freeway usage.
