When we go to petrol station , there is 2 kind of petrol we can pump. The first type which is quite commonly use is charged at RM1.920 per little , another type which is cheaper. The more cheaper petrol is leaded?
My question is .. what kind of car can use those cheaper fuel ?
I am using an old Toyota Corolla 1.5 DX

using 3A-U engine and it is super petrol drinker. It sucked Rm0.21 per KM

I am just curious is my car suitable to use the cheaper petrol ?
What is the disadvantage of using those cheaper petrol
