I just called Shell and their ultra platinum does meet FORD WSS-M2C961-A1 specs. They have not updated their bottling yet but are in the process. FYI for those who search this up in the future.

Warranty and a motor that “may” have issues in 5000-80,000 miles.

Okay, is this a typo? Ford says the oil must meet this spec: FORD WSS-M2C961-A1 In the Pennzoil Ultra Platinum 5w-30 it says: FORD WSS-M2C961-A Shell Specs It’s missing the “1” is this a typo or the “A1” and “A” different specs?

Was planning on 5k intervals.

Thanks. Only problem is I live in Cali and zinc destroys catalytic converters and new ones cost 1/2 a new engine. Can’t win either way.

They discontinued the boss 6.2l v8 which was reliable. And they then introduced the new 6.8L. But I wouldn’t want to buy a new engine that could even be worse. Better the devil you know, then the devil you don’t? I also went in year 4 of this engine hoping Ford figured out what’s wrong. I could...

Did Ford provide documentation to use 5w-40 or was it strictly verbal?

Wouldn’t a 5w-40 void my warranty? They will want receipts. I also remember reading somewhere else that the issue is they are machining the block wrong from the other cylinders and after a plastic part breaks, the engine starts to fall apart. Forgive my ignorance. I just want a truck to last me...

I think I’m going to go with PUPP 5w-30. I like Yellow. 😁

Ok…same service rep with any $1/qt bottle of oil of your choosing? …aaaand go! 😀

Fox, Hypothetical Q: If all motor oil was $1/qt. which oil would you buy for your fleet of vehicles?

Oil type of oil? Am I missing something here? I have the mobile 1 spec sheet but it does not show if it exceeds OEM specs. Is it possible to find out if an oil exceeds Fords MC? CLS? I much learning to do.

I trust oil companies but their hands will be tied by government. Government and its ever increasing draconian environmental hoops force oil companies to lose out on opportunity costs which is to make the best product and dominate the market. So now, oil companies are trying to solve X even...

If you can send some of that good 7.3 joujou to me I’d appreciate it! I was thinking the new 6.8 but didn’t want to get a new engine design on the first year. 🙏🏻

I hear ya but if the oil meets Fords requirements how can they deny me? I’d also say if I use full synthetic I should not have lifter issues in the first place?

Hello all! First post! Bought a brand new F250 7.3L last week! (4 miles on the odometer) Guessing the oil inside is motorcraft 5w-30? Want to change it out at 500 miles. My reasoning is to get rid of the extra metals floating around the motor as it’s breaking in. Did some reading and higher...
