Hi all
would like to get some advice from sifu here about changing the type of engine oil for my exora CPS (105K mileage. 7 years).
currently is using Shell Helix H7 semi synth 10-40W, plan to change to Castrol Edge Fully synth 5W-40.
usage of the my car
1. muse as student transporter car, hence several times (6 to 8 times) of on/off engine per day
2. 90% city drive3. monthly mileage is around 3000Km
4. Reason to change to fully synth is becoz sometimes i could feel the car a bit sluggish. so i drive to have a better driving experience. ( since the car is my cari makan tools, everytime i service my car as scheduled)
5. Reason to choose Castrol is becoz the workshop recommended by my friend only sell this brand....lol ( appreciate if sifu here can recommend other brand which is equivalently good)
Can sifu enlighten me about the pro and con about the change the oil
* higher price tag of fully synth oil compare with semi synth is acceptable for me.
Thanks in advance
Based on this, i think u should switch to 5W30.
But why all the while u are using semi syn, now out of sudden want to change to fully syn?
