TR 5 semi syn

and yes i have ceratec and torco together too, no problem. ceratec costs your engine parts and last for 50k km, means you dont have to "reapply" ceratec until the next oil change around 50k km later. and no, you still need to change your engine oil regularly, just that when you change, ceratec still sticks to your engine.

shell helix is by no means bad, however it is a cheaper mainstream oil, so you get what you paid for.

no idea on penang shops

Would "non API certified" oils void the vehicle's warranty?

Dear Sifu,

any engine oil recommend for suzuki swift (2nd gen) mileage approx 26000
, suggestion to increase fuel consumption if possible.
