Oil Change Question?

[DIB5.0 - PINKY]

Looking to do the first oil change in my '13 GT. What oil do you guys recommend and weight?

 

[07TGGT]

5W20 just like Ford recommends...

5w30 or 10w30.

Only reason Ford spec'd 5w20 for these cars is CAFE. The TiVCT is not dependent on the oil viscosity. For example the 5.0 actually comes from the factory with two different oil specifications, 5w20 and 5w50 (Boss and Track Pack equipped cars) due to their oil coolers and intended heavier track usage. That being said 5/30 and 10w30 have been proven to work very well in a street/performance 5.0

Amsoil 5w30

Go 5W30.

Long story short, in hotter temps, you want a thicker oil so there is less break down, especially if you drive the car a lot.

I use Mobil 1 5W30.

 

[BAKnBLK2010]

I've been using 5w30 myself in both my 5.0 and the wife's 4.6 Explorer.

Amsoil 5w30

^^This is what I'm running, of course I'm just a little ole 3V

I hope this doesn't turn into another oil debate. But I run Amsoil 5w20

I concur. And quite frankly without this turning into an oil debate, anyone who actually thinks ford recommends 5-20 because that's what is best is an idiot. The point seer brought up is proof of that.

I'd also like to add 0w30 works quite well too.

 

[AnotherS197GT]

I assume 5w30 is acceptable for a 3V as well?

I run nothing buy 5W30 in my Blown 3v
5W20 gets too thin during summer when driving your car for prolonged periods.

Its added protection. You will probably get less MPG (marginal) running 30vs20, but it is worth it.

I've run nothing but 5w20 but now that it's getting hotter and the mileage is high I'm switching to 5w30 tomorrow

Both of you think that running 5w-20 will result in better mpg than 5w-30? I disagree. I'd like to see the data that backs that up.

Mystickeith, why do you call me an idiot? Is it because you don't have the ability to state your thoughts without using insults? Is it because I've read the specs for stock clearances and know they are super tight?

Did you know that in every spun bearing thread I've read the owner was using 10w-? with stock clearances?

The clearances are really tight. I don't think 5w-30 is going to hurt you too much but yes, I believe 5w-20 is best for a stock mod motor. There are too many examples of multi hundred thousand mile motors out there for me to believe otherwise.

You might want to check out how tight Ford is able to machine motors nowadays. It's pretty incredible. Keep in mind that a .001" clearance is actually .0005" on each side. The oils job is to keep an oil wedge between the bearings and journal. Too thin and it won't hold up, too thick and it won't be able to keep up with the oil that's pushed out, temps will also increase if a constant supply isn't maintained to absorb heat from the parts.

Thirty years ago when I was driving a 1971 Chevelle with a 350 10w-30 was the standard. But back then motor quality was luck of the draw and machining wasn't as precise as it is today. I know someone on here knows what the main bearing clearance was on a 350 made in the 70's. It's alot different than a mod motor.

I really wish these types of posts would go to the oil debate. I hate reading inaccurate info and when it comes to oil there's alot of people who can only repeat what they read on the internet. Do yourself a favor and look at the specs, look at the incredible longevity mod motors have when serviced as Ford recommends.

Clearances for the 4.6 3v and 5.0 4v can be found in the workshop manuals. Here's a link for anyone who is interested: http://iihs.net/fsm/?dir=0

Run what you want but name calling because someone doesn't agree with you just shows that you don't have anything to back up your opinion.

These threads usually get a few oil salesmen drawn to them. Sometimes I think they are started just to get a debate going so the oil salesman can come in and give his opinion which also leaves links to his business or company. I actually left mustangforums because an oil salesman vendor was given free reign in threads. It always started with a new member asking about oil. It was a pattern. IMO quite a few people don't know what oil really does in their motors. I don't claim to be an expert but I do trust the Ford engineers based on their results with the mod motors for 20+ years.

Sorry.

Dave, can you move this to the great oil debate and slap the op for putting it in chit chat? Lol.

Explain why the 5.0 is spec'd for 5w20 and 5w50... same motor. Exactly, 5w20 is only for CAFE. I've personally not seen much of a mpg loss running 5w30 in my 5.0.
