Is 5W50 the only choice of oil for this car to be warranty complaint?


Yes, says specifically for Track Pack cars to use 5W50.

Common sense tells you shenanigans are occurring when one engine specs 5w-20 and the exact same engine in a very similar application spec 5w-50. Track pact sports an oil cooler which should make the need for heavier oil even less likely.

I didn't suggest 5w20 but rather the more readily available and better value M1 0w40. If it's true the 5w50 will shear into the 5w40 range, why not go ahead and buy the better value 0w40 that has a more potent additive package. Your going to pay a pretty penny at the dealer for 9 single quarts of oil.

The 2 jugs of M1 = $50 or less, about half of a 5w50 change.

On a side note if you don't get a good price from your dealer you can buy a kit of 9 quarts MC 5w50 + the filter online for about $120.

The thing that bothers me is how many 5w50s that are available is too limited. If you decide to experiment make sure you give Redline 5w50 a try.

There's a lot of people on here that think thinner oil is better for some reason. To me, 5W-20 in a Mustang V8 means scarred up cylinder walls and scarred up connecting rod bearings; not to mention everything else that needs lubrication.

Amazing isnt it? This forum is not as useful as it once was,alotta wanna-be oil engineers on this site for the most part anymore.

I would use the recommended Motorcraft 5w-50 during warranty. Why not? It's a competent enough product and will keep Ford happy should something happen.

After warranty, I might continue the Motorcraft product. Again, it's perfectly competent, and I don't mind a thicker oil. Mobil 1 0w-40 might be tempting after warranty, but I probably wouldn't change.

Most of the time members here act like the world is going to end if you use a different viscosity than is recommended by the owners manual. However, they seem to be encouraging to use a viscosity that is much thinner than the manufacturer specified. Most of the time people on here say trust the owners manual and engineers who designed it. However, its seems as if a good portion of these members don't practice what they preach. As another member said earlier, it really undermines your credibility to recommend a 5w20 in an engine that specifies 5w50. I know that it is the same engine, but the one in the track pack is not neutered. What's so bad about using a 5w50? Is it too thick for most members here? I know that it's not readily available but I think that the OP should stick to the owners manual and trust the engineers who designed the engine and car.

Maybe the answer is that the engine is versatile enough to use anything in between 5w20 and 5w50? Everything is dependent on what he's going to do with it and it doesn't sound like it's going to be tracked. Let's try something different here maybe meet in the middle and run some PU 5w30.

I still think it's yet another perfect fit for M1 0w40.

Did the vehicle come with an OEM users manual?

Did the manual make reference for new owners who have concerns to feel free to consult the following internet sites just in case we missed something in the design process.

Amazing a vehicle is purchased on the assumption it will give pleasure to its owner to drive or its a long term investment however, the grade of the recommended oil is questionable and it is a stumbling block maybe.

Why stop with the OEM engine oil grade while we are on a roll lets find suitable replacement for the OEM recommended engine oil cap if you are changing the grade, spark plugs, air filter, fuel filter, transmission fluid, power steering fluid, brake fluid, wiper washer fluid, differential fill, coolant fill, spark plug wire leads, wiper blades, fuel type or rating, fuel cap, reprogram the ECU, dust caps for the tyres, tyre pressure, interior cabin light bulb, headlight bulbs etc even though it is under the warranty period.

The above logic is just as plausible as some of the recommendations I have read in the earlier posts IMO.

 

[SteveSRT8]

pretty simple for me.

While within the warranty period (and if you care) of course use the factory recommended oil. Anything else risks an expensive lesson.

Out of warranty you can fool around a bit once you know temps and pressures. Anything else is guessing...

Welcome to BITOG! This is the kind of round-and-round debate we have about oils just about every week. There is the continual back and forth between the "thin" and "thick" advocates. The goodness of MC 5w50 has been a hot-button issue on this site for a while now, and you re-ignited it with what you thought was an innocent request for advice. I think the part of the MC 5w50 issue that mystifies us is why Ford chose to jump over 30 and 40 to recommend 50 in an engine that is only slightly different from the ones that specify 20-weight.

I think that's most of the issue.

The issue here is to change for the sake of change cause you can.

On another website I visit a forum member for mods to vehicles has as his signature line "The OEM has design engineers and fully fitted workshop here we have a guy in the back yard with a hacksaw".

Yes, and the car is equipped with a feature that severely limits power output if the oil gets too hot as well. This feature may not be present on the track-pack version, or if it is, may be at a higher temperature due to Ford expecting you to be running the oil they told you to run, not what you think SHOULD be in it because you feel you are smarter than their teams of engineers

That's the case with ANY engine. Cold oil is basically always too thick. And ALL oils thin as they increase in temperature. But if you limit the maximum temperature the oil can get to, you can run whatever grade of oil you know will protect it within that temperature range. Since 5w-20 is going to be better for fuel economy (and in turn, CAFE), fitting the standard GT, which isn't designed to be tracked, with a thermal castration mechanism to keep oil temperature in check by pulling power allowed for Ford to control viscosity by controlling oil temperature. Essentially, they ENSURE that the oil CANNOT get too thin by limiting the output of the engine.

The BOSS 302 on other hand was designed to be tracked, and subsequently was spec'd with heavier oil and a factory oil cooler. So not only was Ford attempting to control oil temperature the good old fashion way (without the reduction of power output) but they also saw it necessary to spec a much heavier lubricant. This would indicate that they feel that the oil WILL get above the safe operating temperature of their 5w-20 product, or even their 5w-30 product, both of which they already had on the shelf.

This carried over to the Track Pack version of the Mustang GT, which was fitted in a similar manner to the BOSS 302.

However the answer, regardless of how happy the engine is to operate on any grade depending on oil temperature, is to run the approved product as per the owners manual while under warranty. It really IS that simple.

The warranty is dependant upon adhering to the terms Ford defined for it. There's a recent thread about somebody who is seeking warranty service on the screen for his infotainment system in his new Mustang and is having an awful time trying to get Ford to fix this $100.00 part. Do you think Ford is going to be like "oh yeah, you ran the wrong oil in your $20,000 engine, don't worry we'll replace that under warranty NO PROBLEM! And here's a rental GT1000 for your trouble!".

Thanks! It looks like they're using the one size fits all mentality with this engine too. Personally I prefer choices and deciding for myself based on how the vehicle is going to be used.

It appears Ford begs to differ with this bad boy. I'd use the 5W50, but I would get an oil pan warmer on it for the winter. Maybe they'll back spec in a few choices at some later date for those who aren't going to beat on it.

This is a forum to talk about oil. Discrepancies on that scale are going to noticed, pondered , and discussed. We don't need a forum to tell discuss the owners manual. It's pretty easy to see what the recommended oil is.
