Due to Ford's new oil spec for my 5.0L (WSS-M2C945-B1) I decided to go with Shell Oil's new Rotella for Gas Trucks...as I trust the Shell brand and this Gas Truck Rotella meets Fords new B1 spec.
PS: Shell is the parent company of Pennzoil.

I like Pennzoil Ultra Platinum but didnt want to use an oil that Technically didnt meet the spec Ford species for my engine (ie didnt want to give Ford a reason to deny warranty coverage).

I have used Motorcraft 5W20 syn-blend exclusively for at least the last 18 years in all my Fords, F250, Excursion, Focus, Expedition, F150. Not one internal engine related failure, in fact, zero engine issues at all (that includes 2 with the 5.4 3valve). Some I put over 200K on. There is my test results.

Why go through all the trouble of out thinking something so simple? When Ford designed, engineered and built the engines it was all done using Motorcraft oil that they recommend using. Ford has been using Motorcraft 5W20 on NA engines for many years and there is no known issue with oil related failures. And God knows if there was a hint of problem it would be posted here.

I think this new gas truck oil is the best option out there for our trucks.

By the depth of the logic involved in the video, maple syrup would be an excellent lubricant. And it would taste better.

Great video. That should clear the misconception some people have that cold oil flows better than hot, just because the #5 is smaller . And contrary to some critics, the cold pour is very telling, as the thicker the oil, the less lubrication when cold, which is when the majority of engine wear happens. You should also check the new M1 0/30, which is SN+. That's what I used, precisely to minimize cold-start wear. Curious how quicker it flows when cold against the 5s. Looks like you need to make another test with the other mentioned brands .

Oil pumps are positive displacement, so all of the oils in the video will circulate just as fast through the engine as long as they are in a liquid state (which they clearly all are and would be even to colder temperatures). Cold flow is merely 1 of many different variables that impacts an oil's performance, and if it were the most important variable every manufacturer would all be running 0w-16.

Like the people who keep saying great video.

This is some weird stuff. The complexity of creating an account on the forum should stop this nonsense but somehow it gets through. Choosing not to know.

By the way, hot water freezes faster than cold. So, you should swap your thermostat for a colder one to make sure you don't pop your "freeze" plugs. And, this is another reason to have a cold air intake, because your engine will run colder (obviously, with colder air entering) so the odds of freezing your coolant decrease. Because hot water freezes faster.
