Synthetic Oil = Rebuild Motor!!! OHH NO

I guess the posts you read weren't very thorough, then, because it's pretty much a well known fact that after an engine has reached 25k on regular oil, it's not wise to switch. And you switched at 145k??? That's just plain nuts. Unless it has had synthetic oil since it was a baby (post break-in), NO engine should run synthetic at 145k. Unless the oil is religiously changed every 3000k, conventional motor oil will create more wear than synthetic oil will. Switching to a slicker oil that doesn't adhear to worn surfaces the way conventional oil does is just asking for trouble. Recheck all those sites you saw that advised you to switch, and if they don't also explain that it's for new engines only (as opposed to switching with a high mileage engine), tell them pitch in for your bottom end kit.

Take care,
