[craigsez]

Only ever bought 1 brand new truck and when i got it with 300 miles,i wanted my oil changed..Had it now sence this time in 16 and done changes roughly every 3000 miles......To me the 1st few changes are most important,gotta keep the break in crud outta the engine..Truck only has 13000 mi on it now..As for oils,startede out with what ever dealer used to rp then mobile 1 and now pennzoil super duper platinum stuff..

I'll give you a hint, it wasn't for the longevity of your truck. If you believe the gov't, then it was because of gas mileage. The bottom line, they have chosen that for you, it wasn't your choice. But in your case, maybe what the gov't told you matches your values. run that 5w20

5w20 isn't that bad, but they also took out zinc, calcium, added ethanol to gas, and may other things that go away from longevity of your equipment.

There’s a lot of things I don’t believe the government but I’m not talking about the government, I’m talking about the factory that made my truck.

I just want good oil. I want what’s best for my truck but I don’t want this basic, “listen to me, do what I say and don’t ask questions” attitude. If 5w-30 is better for my engine, I don’t wanna hear “government conspiracy” crap...lol.

Really when it comes down to it its more opinions as nobody has 10 of the same motors with 5 running 5w20 and 5 running 5w30 of the same oil under the same conditions.

I run the oil I run because of the additive package and run the weight I do because I feel its better for the motor I have never bought 20w and never had a problem with 30w or 40w oils.
I also feel they are suggesting 5w20 to meet CAFE standards for fuel mileage and no other reason.

None of the guys running 30w or heavier are having any weird oil pressure readings or oil temp differences.

When it comes down to it either oil would probably take your motor through the life of your truck.
Only one thing worries me about the thinner oil and thats the cam/lifter problems that some guys have ran into.

Thats my 2 cents.

Another way to look at it is take this same 5.7 minus MDS and put it on a 2500 and 5/30 is ok, or the 6.4 with the exact same MDS lifters and 0/40 is recommended. It's hard to believe that MDS is the issue, it's all about the tree huggers.

Rod: proved many moons ago the MDS system used in the 5.7L & 6.4L had All the same part #s.

Corn: Believe it or not our evil corrupt government has a huge input on what & how these so called Factories build for us to buy! Achieving a certain mpg is top priority as well as emissions.

Oil viscosity factors in this in a large way.
Longevity of these creations is not within this same list!

Good luck too you with your search of the Perfect Golden Elixir!

Please I say this again for the hundredth time probably:
Don’t get suckered in or brainwashed thinking or believing that 5W-30 or 10W-30 synthetic is a thick viscosity Oil!
It’s just the simple fact that 5W-20/0W-20 at operating temp has virtually the viscosity of water.

This is why I said blend the 2...no problems if using the same brand and you have the best of both worlds.

I was skeptical at first last year, but my truck started making some louder ticking at startup in cold mornings and this is why I chose to switch to heavier weight and blended them to get about 5w-25.

Over the past 6000 miles and approx 1 year I have observed, read, and researched and just last week when I changed my oil I went with 7qts of 5w-30 Redline. At the end of the day...it’s your truck...run what you feel comfortable with...just get the best 5w-20 and high quality filter.

The 2 oils highly recommended are PEnzoil Ultra or Redline. Both have good additives with moly! I decided on Redline and couldn’t be happier with my decision....my truck will never get anything else!

This isn't part of this discussion, I had a '76 Ford Squire wagon with a 460 c.i. engine (windsor), I started with 10w30 and about 45k I had to start using strait 40w with 2 pint's of stp. Had bad piston slap and bad rods and mains, I ran this car to 93k and then traded it, it was one wore out piece of crap. Sometimes heavier oil dosent help!

And see that’s just it.

You have the 6.4, don’t you?

But you know if they are just recommending that lighter oil just in the name of fuel mileage, then fine, as long as my engine’s fine, that’s all that matters. But how do I feel assure of that?...lol

And the cam and lifter issues is on the 5-20 or 30?

I do agree, but 5w30 is not a heavy weight oil when it comes down to it.

Had a 02 2500 chevy witj a 6.0l with piston slap, very loud motor but 10w40 shut it up..lol

I have the 5.7 8sp 1500.


I believe most that have had cam/lifter problems were running 5w20.

Like Ramnewbie said, they recommend 5w30 in the 5.7 2500 so why is that ? no CAFE standards on the 2500s

Edit..
To go on alittle more, they recommend the 5w30 because the truck will be worked harder so they want a oil that offers more protection for the motor.

 

[Hipps2000]

It’s the government that set the standards the OEM had to figure out how to build an engine that would comply with the CAFE standards...why else would they be touting 22mpg. Now that Trump is deregulating maybe we will see OEMs getting away from 5W-20.

The 5.7 liter motor is the same in the 1500 and 2500/3500. Above It’s stated in the manual 5w30 is recommended in 2500. Why not the 1500?

Ok so, since there’s a big number of advocates towards the heavier 5-30, what’s gonna happen if I tell the dealer when I go in for my first oil change, to put 5w-30 in it?

But anyhoo, what do I trust? They’re telling us to use the lighter oil for better fuel economy or they’re telling us to use it, so they can get us to buy a new vehicle more often?

My truck is approaching 3k miles and needs its first oil change too, would it be safe to just go directly to Royal Purple filter #10-48 and 5W30 PUP or wait till a few changes?

 

[69GWC]

I had a free oil change so I ended up waiting untill I hit 6k to switch to 5w30 Redline.
If it had not been for the free oil change I would have made the switch then.

That’s a good question.

If this was just as easy as them recommending the lighter oil just in the name of mileage, and won’t jack with my warranty or nothin then I would have no problems using the heavier.

Talk with your dealer...mine is great. They’ve installed my long tube headers, ATI dampener pully, EBC rotors and pads, zone upper control arms, zone body lift, bilsteins 5100s, heavier realcoil springs. I have them do all the work on my truck. Some dealers are supportive and some suck monkey balls. If I were you I would run the PUP 5w-20 until you notice some ticking noise. The dealer won’t have the RP filter.

So you have a choice you can buy your own oil and filter and bring into the dealer nd pay them to change or use the dealers oil and oem filter.

Yes defiantly the RP10-48 filter...I would run the 5w-30 PUP

 

[Hipps2000]

I still have 2-3 free synthetic oil changes at my dealership...after I heard some ticking I switched to Redline and now change it myself.

Enjoy the read cornholeious.

Because the 1500's do not qualify for heavy duty, if the manu doesn't show the gov't they do everything possible for gas mileage, they get fined out of existence. However, if you are Obama's *****, well you see how the gov't treats GM and Chrysler with their blood money.
