thanks for the reply everyone, i am using a petron turbo diesel and the gas stations that i frequent were petron at gil puyat corner makati avenue and at alabang along commerce avenue, i wonder how come these gas stations have dirty gas while these are prime stations...

dyan din po ko sa commerce and slex nag papa gas so far di ko p na experience yan.
