I have a question. When it comes to oil grades even though one car specifies that it needs 5Wâ€“30 oil would be fine to switch to a 10Wâ€“30 or 10W-40 oil regardless if its conventional high mileage synthetic blend or full synthetic if one moves to an area i.e. Hawaii southern Florida the Caribbean etc. where warm weather is a commonality or a semi commonality all year round?
Malaysia Little: Depending on the car it will give a range of oil weight specs based on ambient temperature, stay within those ranges. Different engines are designed with different tolerances so what works for one engine might damage another
Marley Steele: Good point Malaysia Little:
Malaysia Little: If you have the owners manual it should have the ranges near the back of it
Marley Steele: Oh ok i gotcha i asked because i heard somewhere once that if you put 10W-30 OR 10W-40 Oil in a car that calls for 5W-30 it can possibly screw up the Engine
Malaysia Little: It can but its a blanket statement that isnt always correct. Sometimes thicker oil is better and sometimes it can cause extra wear.
