Please allow me to caution you about this. What you said is not incorrect, but it does not work that way in practice.I had a good conversation with my service manager about wanting to use 5w40. He said Ford Engineering will never give me a written statement approving of 5w40 but also said that my warranty will not be denied because of it (his opinion obviously). He said Ford would have to prove the 5w40 caused the failure and given the Magnuson–Moss Warranty Act that would be difficult to do. He understood my reasoning for using 5w40 when I showed him the viscosity numbers on my last two Blackstone reports.
I tow a 4000 lb boat a lot and I’m going to upgrade to 5w40 on the next oil change. I’ll keep an eye on the dipstick after that but I’m not going to worry about it. Never before loved a vehicle like I do this Ranger.
Before I go too much into it, let me say, you will be fine running that oil as long as you don't mention it to anyone. However, if you admit to using that weight of oil, all they would have to do is show it is possible that the oil caused the damage to win against you in court. The standard for evidence in civil court is preponderance of the evidence, which is basically they just have to prove there is more than a 50% chance that it is true. Which, if you are in court fighting the type of claim they are willing to take to court will be something like a complete engine failure. It would not be hard to convince a jury that using an oil weight that is not recommended could lead to those types of failures. Also, you would have to file a lawsuit to even get it that far. Assuming they were going to decline your warranty, they would just do it and then it is on you to take action from there.
Now, that being said, feel free to read up on my story here.
I ended up taking the $5000 settlement, but was on the hook for my own repairs. They did not officially void the warranty, but my lawyer said the powertrain warranty was effectively voided because any powertrain issue that came up in the future would be blamed on the tuner and they would decline the repair.
I think the link explains it all if you read all 4 pages of the thread, but I will gladly give more details if anyone wants.
