Which Mobil 1 5W-30 oil?

[NYH]

I wouldn't mind the 6.8 super duty but I dislike that you can't even option the 10r140 with it and have to get the 7.3 or 6.7 to get it. I'd get the 7.3 gas not for the power but for the beefier trans. As for oil I'm not running 5w-30 in either of my 5w-30 calling OHV v8's. I'm using 15w-40 and they're much happier with it. Dead silent valvetrain at hot idle after running for hours in this heat. I'm also using 5w-40 instead of 0w-20 in my new one and it too quieted down to where I can hear the pump unlike before which was a valvetrain clatter fest in comparison. A whole lot quieter and healthier sounding.

But if you really want to stick with 5w-30 and it must be m1 for whatever reason I'd use m1 EP and run it for two intervals which would probably be 10-13k and not worry about it since it's an NA non direct injected ohv engine with a big sump and it not being turbo or direct injected means it's soft on oil.

I couldn't afford any trucks with the 7.3L. I was looking for entry level GMC/Chevy and Ford models. Wanted to try something different then my usual Ram's. The GMC/Chevy guy wouldn't work with me at all. Tried low balling on my trade, wouldn't come off the sticker price and wouldn't return phone calls. I went and checked the F-250 out and like it. Plus, it has way more equipment that I'll use, then the GM's had.

If an oil has a viscosity of 8.5 cst at 100c that won’t be an Xw30, it will be an Xw20. The lower limit for a 30 is 9.3.

Thank you, that was a mistake/typo on my part. The particular one I was looking at was 10.1.

I've heard the lifter issues they were having was mostly with trucks that idled for really long periods of time. From what I gather, trucks that were driven normally, generally don't have those issues. But I really don't know.

What is your opinion of Valvoline Extended Protection 5W-30 oil?

Thanks, NYH.

When there's a deal on it I run it in our Mazda skyactiv 2.0 commuter (GDI) instead of the factory spec 0w-20. At one point I used it in our 2GR-FE, but have moved on to "better" oils for our fairly abusive short trip cycles in that machine. Although it's a fine oil, of the oils available at WM, I wouldn't go as far as saying it's the best for any/every application.

If you felt higher HTHS 5w-30s would be beneficial to your motor/use cycle (HTHS isn't specified on the bottle) but you could look for a 5w-30 with a specification that governs it. For instance, Dexos. My point is, sometimes the certifications tell us more than grade.

I don't pretend that I know more than the OE engineers that specified and tested the lube for the engine, but I do suspect they may have cared about performance in-warranty, credit for long OCIs, and fuel economy, while my priorities are performance well beyond warranty. In the event that you had in-warranty failure of lubricated components, I don't think your oil choice (within reason) would come into scrutiny. I think this is often an overhyped fascination that warranties become deniable if you use products outside of manufacturers suggestions.

I know I asked about Mobil 1 oil, but I went with the Valvoline 5W-30 Extended Protection oil and the regular Wix 51372 oil filter.

Thanks again guys, NYH.

Yes I would do the same I had a Toyota 4Runner that I used to bounce back and forth between M1 and Valvoline. Same viscosity. Kept the engine clean by changing it every 4,000. I saw that Valvoline oil seem to get pretty murky around that Mark because of my severe driving environment. I switched to M1 for my little four banger RAV4 hybrid, but I really don't know why! I changed oil so frequently it's now becoming a cathartic practice for me and I look forward to it! I love the smell of oil especially diesel when it's burning!

As far as I can tell, it doesn't comply with Ford's WWS-M2C961-A1 spec. And I want to stick with a name brand that hopefully doesn't get changed around too often.

Thanks, NYH1.

Sp?

I'm not sure about what "Sp" means?

API SP, which is the latest spec.

I just bought a $56k plus dollar truck. It has 600 miles on it. It has a 5-year, 50k mile powertrain warranty. And I'm going to add an extended warranty. I'M GOING TO USE A MOTOR OIL THAT MEETS FORD'S SPECS....END OF STORY!

GM, Porsche, BMW, Volvo aren't going to cover any warranty repairs so the oil's they use are meaningless to me.

I'm also going to be doing 5,000± oil and filter changes as mentioned.

NYH1.

It's been awhile since I owned a Ford, but I remember the oil change cost being really low on my 2017 F150. Just for records purposes I just paid them to change it. I didn't change the oil until it was out of warranty.

I'd just give them the extra $20 over buying Mobil 1 personally during that time. I also stuck with 5k mile intervals. I ran Mobil 1 0w40 after the warranty expired like I've run in nearly every car I owned. Like you said though, if you're changing the oil yourself I'd stick with the required specification for warranty purposes.

I don't think all API SP oils meet Ford's WWS-M2C961-A1 spec. Just like not all API SP oils meets Dexos 1 Gen. 3 specs.

If the 5W-30 oil meets API SP with ILSAC GF-6A, it meets the intent of WSS-M2C961-A1 whether it has that license approval from Ford or not. You are not going to find somebody denied warranty for it. If you do, I will buy your next oil change.

It’s really only a problem if they ask for a receipt for materials for an oil change to cover the time frame in question. That’s not a likely occurrence.

I really don't know why we're still talking about which oil I'm going to use. I said, I went with Valvoline Extended Protection 5W-30 oil.

I don't care about meeting "the intent" of the WSS-M2C961-A1 spec. If it's not approved by Ford, I'M NOT USING IT!

Absolutely not true. My buddy had major engine issues with his 5.3L GMC, burning well over a quart of oil per 1000 miles, terrible piston slap. He had to show receipts of his oil and filter purchases. It was a nightmare.

If you were really worried about the warranty, you would use Motorcraft oil and filter during the warranty period and be done with it.

Then don't. But understand it isn't an approval nor a license. That's a material specification and can be met by a variety of blenders. It's not a condition of warranty either. Your manual does not say that.

M1 comes in a number of different formulations. While I can appreciate that the "regular" formula is perfectly adequate for 5k changes, I can't help but wonder why that would be the choice when the Extended Performance version is only $2 more.

I've used EP exclusively since purchasing the Camry, and have found that many times the EP price and "plain vanilla" price are the same. In any case, a $2 or $3 difference for 5 quarts of oil once or twice a year wouldn't influence my decision. OTOH, if money is tight, as it is for many, and has been for me, saving a few bucks is a worthwhile endeavor.

 

[Shel_B]

If you're not in the industry, how do you even find this out ?

You are in the right place to learn about such things.

I don't need to use Motorcraft oil and filters to have warranty covered as long as they meet Ford's specs. You're being ridiculous.
