i i were to extend to 15,000 KM oil change interval i would fo for the Top 1
but if i were to go 12,000 KM only i would go for the delo 400.

either way both are good oils. budget will be the definitive factor in choosing between these two oils. Top 1 SDO 10w40 is more expensive than Delo 400 Gold last time i did a motor oil price check.
