So I am still struggling to find solution to my oil problem.
My car probably always used 10W-40 as it is like what 99% of mechanics in my country put to your car.
I came to a shaddy list on the internet saying the recommended oil for my car was 15W-40, and I changed it to it, gradually, I had an oil leak and I just started adding the 15W-40 as the 10W-40 would leak.
Conclusion is that my car struggles to cold start honestly, very loud on the first ten seconds and the throttle just goes crazy on the first four seconds going up and down as the engine tries to lubricate itself. So bad choice on putting the 15W-40.
So now I need to change it again. My questions would be, what oil to use on this twenty year old car. It is fully mechanical and the engine heats a lot during summer.
I got recommended by a guy (not a mechanic) to use Petronas Synthium 7000 0W-40, he says it is a lot more fluid providing better cold starts and much less struggle, while providing the same density when the engine is hot as my current oil. He also says its additives will help the engine cool down a lot more and take better care of the engine.
Then I go to a mechanic and he says that oil is better for trucks.
So problem right now is I do not know what oil to use. The car is old and I would like an oil that takes care of the engine better as I really like this car and I want to drive it for many years.
Oils thicker than 10W-40 is not in question, I cannot use them. I can use 0W40, 5W40 or 10W40.
When the car had 10W40 it still struggled a bit to cold start but it was okay.
But my idea is to give the least effort for my engine to start, but before breaking my engine I would like to know what others with knowledge on the matter say.
