[SIZE="3"]Elow Guyz...Have a Q here...

Which of the two would you prefer?

1) Using a SYNTHETIC oil and have an oil change every 10,000 Km
2) Using a MINERAL oil and have an oil change every 5,000 Km

????

Which of the two will give a better protection to your engine?

Comments and suggestions are highly appreciated...
