Hello guys!
I have some questions, looking for assistance:
i)Does each engine require specific engine oil viscosity grade?
ii)Does each engine has specific engine oil pump design? How does oil pump design determine oil viscosity grade?
iii)If I use different oil viscosity grade, any effect to the engine performance?
iv)For a passenger car don’t have VVTI system and operate at 10 to 40 degree Celsius environment condition, any effect if use 0w30/5w30 viscosity grade engine oil?
v)For old truck(run 200k miles), use of more advanced oil(synthetic) could help to extend oil drain interval?
vi)Any effect of use engine oil treatment(STP) to engine performance?
Thanks.
