Depends on the car
Technically this very oil is good for 15000 miles/25000km but that's with Mercedes and Porsches with very large oil capacities and special filters
In a regular 4 cylinder Toyota with less than 4 litre oil capacity 7000km is a safe interval
Shopkeeper says you can use this oil in Corolla for 8000km or even 10,000 km of you do a lot of highway driving
