hi guys! i'm planning to try out PETRON REV-X HAULER on my diesel ride, problem is i can't find it in our area except for PETRON gas stations which sell them at a high price! 125 pesos i think.. judging from the databas thread here it should only be 85 pesos??

in autosupply shops here i did find the Petron REV-x HD sold for 75 pesos a liter, database price here is 74 pesos yata??

i'm inclined to try this because of the very cheap price and yet it conforms with the oil rating my engine needs.. it's even suitable for Turbocharged engines.. the PROBLEM is, why do gas stations sell their products so high???


so where do you guys source your oil??
