My next door neighbor bought a 2005 Honda Accord with 60k miles on the clock in excellent condition and the owner said he used O'Reilly full synthetic oil and Bosch filters and there was right now a deal for $21.99 for a 5 quart jug and filter and changed the oil every 5-7.5k miles and this is Southern California where weather has been cancelled by popular demand. Now the adventure begins. The service writer at the dealer where he took the car for service told him that oil would ruin his motor and the filter was no good. They recommend (demand?) Castrol Edge and Honda brand oil filters. I told him to find service somewhere else. The next place told him again that O'Reilly oil was junk and he recommended Mobil 1 and an M1 filter. On top of that he was told he would have to change the oil at a thousand miles or so a couple of times to clean out everything that was left behind by a cheap inferior oil. I told the neighbor to keep looking. What do you think?
