No where did I say that Conventional was better than Synthetic. My whole point is that whatever oil one chooses to use will work fine, as long as it meets/exceeds what the manufacturer recommends and is changed at proper intervals.
Most oil related problems are due to the fact that owners use improper oil, or do not change when recommended.
The point of this topic was about GF-5 standard. Conventionals will be able to meet that standard.
Is that wrong?
