That means if I run it for a longer period than 5 minutes. Witch is 6 mins or more ...... Lol. I'm kidding. Tbh. I don't care if it blows up. Lol. Truth. But it's not burning oil. There's nothing bad in the oil. I've had it tested 4 times since I've had it. Why? Because I check the oil in the car. It's only a few more $$ to have another test done. So with that being said. That's about all u can do without pulling the head And I'm not doin that again. Lol. So it will b a call to Ford. Come pick it up and fix it. Lol. All ford racing parts warrentied by ford.

And honestly. I've heard it a handful of times. And it was balls a$$ cold out when I did

Yet my decade old 4.6 is still quiet as can be...you can hear the injectors if the hood is open but that's about it haha. The 5.0 needs to take notes so that it's perfect lol.

I know I have full warranty to 200000km, that's all that matters to me, if it piles up, Ford puts a new engine in, their problem not mine. The truck will likely be traded off before the warranty runs out so I'm not gonna lose sleep over it. 135102km left before I have to worry about it.

Rhino - my knocking 5.0 will still eat your 4.6 for breakfast on the road or off of it! lol jk

I kind of get what you are saying about how it is not your problem. If you need to make a claim and go through the process, I wonder if you will still feet that way? I also think if there is a problem you want to document it. I went back to refresh my memory. I am not sure what oil the dealer is using and I really want to do it myself anyhow, but I have zero issues using full syn.

Mine gets full synthetic Mobil 1 5W20 and a Motorcraft filter every 8000km, as per the dealership's recommendation due to the excessive idling time.

Full SYN here too. Mobile 1 and motorcraft filter.

Smart move. I am using the same oil. You probably have something in writing. Why do you (your car) idle so much?
