Didnt someone get water in his engine. Had a service which included an engine flush. Engine went bad and dealer would not warranty because of the flush.

I believe the dealer saw a small water stain in the air box and denied it. He did have a flush done, then spun a bearing or two I believe

A flush is meant for severely neglected engines that don’t get regular oil changes. Even then, I’d be cautious. It can loosen up sludge that’s in a “safe” area and relocate that sludge to an oil passage and block it. Just change your oil.

Used to flush high mileage vehicles by cutting old oil that was being drained 50/50 with kerosene

Thanks all for your input. Seems like the risk-reward isn't worth it. I'll continue with 5k synthetic oil changes. I do wish the 2.7 was a bit more refined, especially when cold, but it is what it is.

I think the owners manual specifically states that any oil additives not from Ford will void your warranty. I"d think even at a best case that stuff won't do anything.

Why do you say the engine is unrefined? Mine is loud at first crank and for about 30 seconds until it idles down. I am not worried about it though. Is yours just loud or is it making noise that it shouldn't, like your cam phasers are bad.

I don't have the cam phaser issue, thankfully, but it is louder than "normal" with some vibration. I don't think it is anything out of spec or any problems, but wondering if there is a way to make improvements.
