5W30 oil

[Grumpy Bear]

Psst! 

I don't care!

 

I made my case. I provided ALL receipts. Said everything I have to say. I've shared every failure and every triumph and there have been far more wins than losses. I've hidden nothing. Iied to no one. Mislead no one. Demanded nothing from anyone. Fact is, anyone who has read my scribblings for any length of time would have seen some fairly systemic shifts in what I write as my knowledge morphs. I'm not ashamed to be wrong  nor to learn from others. Helped those I could. Learned from those kind enough to teach. I don't sell anything. I don't profit from sharing. I profit from the research I use to share here and I don't have to publish to profit.  

 

So when I get flack from some self promoting "hand wavers"  I just don't care.

 

Not a single word said, not a lie told, will impact the service life of my equipment. Put a single dollar in my bank account nor take one from it. Keep me from dying or put me to death. Be my spiritual salvation nor judge me in any meaningful way. Place food on my table or heap famine on me or take a single thing from me I care about I won't get back a hundred fold.  

 

Honest hearted people will understand that and know I'm but a PM away. 

 

I left your 'club' and will no longer contribute there. I'm going back to journaling.

Hi all, I have a business and need my trucks to run.  I strongly believe its a good idea to run 5W30 versus 0W20 in this engine.  I run the cheapest Dexos/API SP 5W30 I can find and change it every 3000 miles.

 

I see some off topic commentary going on.  Im not going to join that because Im simply too busy over here.  The bottomline is my trucks need to run.

 

Probably the best idea is to run a high mileage 5W30 as all engines leak as you add milss. So might as well use HM oil sooner than later.

Did you read above in this thread?  ENGINE OIL VIS DOESN'T matter as much as : 

 

Use recommended viscosity especially if you change every 3000 miles.

 

If you keep your business trucks air filters changed every 10,000 or less in non dusty areas, heavy dust change at 5000 or less miles, plugs relatively fresh ( change every 60,000 miles), driveline lubricants at least synthetic of moderate quality. 

 

If you don't do your own maintenance take it to a Valvoline place and use their products of lowest cost that meet the specs. 

 

[Bruin19]

I have done all the research on this topic I possibly can do.  The plugs on this truck can go to 75000 miles and the air filter doesnt need a lot of changing.  The oil should be changed every 3000 miles for severe service.

 

As for oil viscosity this engine has a problem with leaks and oil burning as well as lifters.  You need to use 5W30.

Wish you well, some can disagree and consult. You take everything personally if you don't get your way.  Last chance for you Brother, really do wish you well.  PSSSt I do care about others more than self.

Come over to the science side and read up. That is if you want to learn. 

Ditto, I'm in the club and don't have time to watch the oil guys argue ad nauseum about chemistry...

 

The question is simple: What is/are the best engine oil(s) for my truck? I might even dare to complicate it with, my oil change interval is x and my operating conditions are y.

 

Instead we get blasted with this endless mind numbing reading under the noble guise of "learning", "do your own research", "educate yourself on my teat of knowledge".

 

Naw, I'm waiting for a meaningful takeway from the club. It isn't there, so I agree with your approach. Common sense.

 

GM recommends a certain oil for certain reasons... see results - oil consumption. It didn't leak out, it didn't evaporate, vaporize or otherwise vanish into thin air (before anyone starts - stop) in any measurable amount in my driveway. So where did it go? I agree, out the tail pipe, via the combustion chamber. How to stop it getting there? Honey vs water in a bottle, which one gets past the opening faster? Duh, thinner product gets past openings faster. 

 

Last oil change on my Yukon Denali I switched to thicker viscosity to lessen consumption. Standby for results in 7500 miles.

Your response is reactive. You know it is. You waited until you had a problem before you took action, REACTIVE! 

 

Ya dropped your coffee cup and now think you can make it whole again with honey. 99% of people follow this pattern. You even admit that in, "GM recommends a certain oil for certain reasons... see results(?) - oil consumption.(!)" 

 

And almost everyone thinks it's a one item on the checklist issue. Let me guess, Viscosity. Well, yes and no; and it depends. On what you say? On the DAMAGE DONE THAT IS CAUSING THE OIL CONSUMPTION. 

 

Did a lack of dispersancy and detergency plug the oil ring land returns and flood the scraper rings? Did overly long OCIs do the same? Did a lack of VISCOSITY wear out the bore/ring interface? Did a lack of sufficient AW additives get overwhelmed by overly long OCI's killing the bore/ring interface? Did a lack of polarity dry out the valve seals. Did a lack of detergency and dispersancy plug up the oil separator and PCV system? 

 

BEFORE you have an issue, use more viscosity than you think you need or the OEM says and with an oil that has enough AW/EP to be effective and makes the EPA cry and change the oil sooner than to book says by a bunch and find one with enough polarity to enhance cleanliness so you don't have to be REACTIVE.

Problem with common sense it isn't commonly used. A guy sees this situation repeat itself over and over and thinks it will be different next time. A lack of common sense thinks the OEM and those PROFESSIONALS following the lead of the EPA and C.A.F.E. are gods that have their best interest in mind. Heck, they have allot of letters behind their names so yea, they must have it bagged.  And yet you're fighting a problem and plugging your ears. .

 

Tis why I withdrew from that club. People more interested in being right than doing right. Trying to do the wrong thing right. 

 

Second rat gets the cheese.  

 

You may be able to prevail if there is little mechanical damage (loss of crosshatch and seal face integrity) with a effective cleaning of the rings and lands, and you will have no chance if there is, not matter how heavy the oil is.

I would not do a 7500 mile oil change.  Keep it at no more than 4000 miles.  Why?  Varnishing.  If you do greater than 4000 the interior parts of the engine will get varnished a golden color.  The color of those parts when new is silver/grey.  If you look at the dipstick what is the color at the tip?  Silver or golden?  The varnish can eventually fall out and turn to sludge.  Every failed lifter problem seems to have golden lifters pulled out.  

 

0W20 is to help GM meet CAFE fuel economy goals.  5W30 is not only thicker but a tougher more durable oil.

 

5W30 is specified for other applications of the 5.3/6.2.  I believe its 5W30 for the Camaro.  5W30 was also in earlier years of the 5.3 like pre-2015.  Ive had it in my truck driven all over the tri state every day for 6000 miles.  No issue.  

 

Look into an engine flush like Liqui Moly Engine flush.  I have done 2 such engine flushes on the 5.3 since new.  Keep the engine clean.  The engine flush takes about 15 minutes done before the oil is changed.  This will also help get rid of varnish.  I used 2.5 cans for my flush.

[Bruin19]

This is where Im at right now....truck is 2 years old purchased new.

Miles  64205

Engine hours 2350

Average speed 27 mph

 

So its 100% a work truck which cant go down and get stuck in shops.  Thus my concern in these matters.  I do 3000 mile oil changes, do engine flush, etc.  Recently just 6000 miles ago I switched to 5W30.

The ONE PERSON who argues is @Grumpy Bear and he’s gone. 
Ask at the club and get answers. Based on testing science and experience.

No, it’s because you are the one who argues and claims things in big letters with odd memes when you get called out. 

Tender ego’s can’t handle science. 
 

Others Ignorance and laziness can’t either.

Oh young one science is all I do. That 'chicken blood and bat wing crap you do' you call 'art' is neither art nor science.

 

Wasn't my ego that had me leaving. Your bait and club style of expression. You are the reason I withdrew. Self aware you are not. 

 

Congratulations. You've turned your new Forum into another BITOG in record time. I didn't joint there because I got a gift there I didn't get in yours. A preview.....

 

Last thought. You are blocked and you know it so this hit and run BS on my persons is straight up cowardly. Grow up and get a grip.

Normal operating conditions.

 

WHAT IS THE ANSWER?

 

If a recommendation can't be made based on that information its a waste of time. GM makes recommendations with the same assumptions. If you can't do better with a whole club of knowledge then holding GM to a higher standard is hypocritical.

 

I KNOW I can get 250K miles using GM's recommendation, with oil consumption.

Who is arguing to? Internet troll farms?
