As for synthetic having adverse affects on the engine, that's a first for me. What were they running and under what conditions?
i'm not even sure.. i'm a bit skeptical of their thoughts that the synthetic did cause them problems, but i'm just putting it out there people do feel that way.
imo as well, synthetic is much superior, but if one keeps on top of the oil changes with dino, it's just as effective.
