I used 5 w 50 castrol and changed every 5 000 km , i could have gone longer , but why ? I believe oil is the life blood of my engine and frankly its the cheapest form of insurance for the car. If i went over 5000 km then its ok , the oil and filter supposedly go to 10 000 km but why test it lol .....
Im interested to know what the standard viscosity of oil is for your car from the factory and if running a thicker oil in a turbo car is a good idea ? i've been slightly shy to mess around with viscosity numbers in oil on my new car since im worried about the oiling system being designed for one type of oil and changing viscosity might affect flow rates to the turbo and such .... i dont want to fry the snail :)
