So you put 150 worth of diesel or 4.5 liters, if your tank is 45 liters, that's a 10% mix, I would assume your tank is almost empty and you just placed 150 kesos para mabilis at enough na ito para umabot pauwi. Even at half tank full, sya 25 liters, then the mix would have been 18% or 9 point reduction in octane rating, kung blaze gamit mo down to 91 ka, pero kung 91 gamit mo?
