Am a noob when it comes to changing oil and engine oils and have the following 3 questions:
Is Gulf Western a good engine oil? Specifically the Synx 3000 10w-40
How do Repco and supercheap deem a part suitable for each car and which one is more accurate? One site says the above oil. Fits my car and the other says it doesn't but the manual says 10w-40 is fine.
Is Castrol Magnatec any good (or at least better than the Gulf Western Synx 3000)? Is it true it leads to increased sludge formation and doesn't change well on oil changes?
TIA for any help :)
Car make and model?
If you're driving anything that resembles a camry, stop reading online and buy any 10w-40.
if you're driving a V8 or engine thats running turbos and putting out 500HP at 7,000RPM maybe you're probably justified in caring more.
