2014 5.3 Silverado excessive oil consumption

I wonder if the Rotella Gas Truck has more of what is called a 'demisting' agent than your previous oil? 

 

With GDI we also got VVT and vent systems that no longer have vacuum check valves that rely heavily on baffling, orifice size and load based vacuum to control carryover. When I think of an 'oil burner' I think oil getting past rings but it seems the majority of oil usage in these newer motors is vent carry over. Yes, I realize it seems I just stepped in it given my stance on catch cans. . 

 

The 4.3 in my truck has never been an oil 'user'. Nothing I can measure in 5K miles but I drive very conservatively, low rpm over long distance with few start/stop cycles. Gearing is tall and so on. On my rounds I am passed by nearly everything so I know the lives of most 5.3's, in my area anyway, live at much higher speeds/loads. Makes me wonder how a 5.3 would do driven as I drive? 

 

Not promoting a driving style just asking the obvious load/rpm/vacuum based questions and their possible effects on the factory vacuum system tuning. Ya know, orifice size, baffling type and amount and so on. 

Interesting.....I should have some data here in a few...carry on..

I plan on being around this forum for a while.

We will see about oil consumption and longevity of my 2012 5.3.

Mountain driving in Colorado and towing are the norm.

 

I plan on driving this truck until I get the dirt blanket.

Or at least 200 K miles if I live that long.

Doesn't matter what oil is used as long as it meets spec.

I have stated before this motor is quieter than when I bought it used with 41 K miles on it.

IMO shorter oil change intervals is the key.

Don’t agree on using basic oil meeting lowest requirements but I’d have to agree with you on the shorter OCI’s. Buy what you can afford and do it often, keep these engines clean!

We all know your stance on oil TXGREEK.

I have never had an engine failure in my 50+ years of owning used vehicles using off the shelf oil.

Works for me.

What are your recommendations on sooner OCI’s? Imho and if using low of the mill basic get it done oil that passes off as minimum requirements would not suffice because it’s breakdown would be sooner rather than later. My wife’s new X5 uses Castrol and seems to need OCI’s sooner than factory recommended 10k mike OCI’s and the Castrol in Germany is supposed to be superior to the Castrol used in the US. Oil has become so complex due to manufacturers realizing the much needed additional protection and cleaners needed in order to just keep the vehicles produced by the manufacturer running long enough. If what you’re doing is working for you then that’s great, don’t need fixing if it isn’t broke, hopefully never will [emoji6]

Btw, didn’t GM change their OCI’s to sooner rather than later too?

I’ve never had an engine failure going extended with Amsoil. That counts dozens of gas and diesel vehicles and much more off road diesels. That being said engines change. I wouldn’t dream of doing that with many miles with these so called modern engines. I never had a reason to use a different brand. I do use dealers and their oil now simply because of more frequent oil changes.

Hey Grumpy can you do the math per year for a guy that really uses his truck say 30k a year? amsoil or redline x$ or a synthetic blend @$28 per5 quarts based off 3k intervrals. Just interested is seeing the cost.

Sooner rather than later oil change intervals seems to be the key to longevity with these motors. Amsoil no doubt gives the best protection in oil but not really needed if you’re doing 2500 mile OCI’s, I wouldn’t want to find out but my 4K mile OCI’s are doing excellent so far with outstanding engine performance to boot. If I wasn’t hooked on the impressive performance from Amsoil Signature Series I’d be using same price over the counter motor oil like I was until I wised up and found much more bang for the buck. I’ve also heard that minimum requirements is something of legality used by manufacturers in order to protect themselves from engine failure lawsuits. There’s a minimum and then there’s outstanding, choice is yours. Good luck to everyone and hope everyone has an outstanding 2020!

Truth is Mook I don't know. Just a thought experiment presently. I base much of it on the changes to the oiling and vent systems GM made in 2014 for the then new Ecotec3 motors, and the subsequent bulletins published since. Add to that a few mistakes of my own I learned from. The 'revised' baffle and pump systems were boasted to have increased oil separation leaving the breather systems by 300%! Evidently they have a means to measure this. Mine, for most of her life has had the tube to the intake bone dry. Then one day I had to disconnect the MAF and afterwards, for one key cycle, the oil pump stayed in the second stage and that increase in traffic put some oil in the breather tubes. High(er) rpm would have about the same effect. More oil, more beating it to a pulp. It dried back up when the pump returned to normal service. 

 

As little trouble as I have had with this driveline over her 107K mile life so far, I fear to boast. About the time I do....BOOM!!

I have one vehicle coming off warranty this year, 10 years less than 100K miles. I had everything done at the dealership. The recommended oil change was just under 4K miles. The engine doesn’t even have direct injection. There’s no reason not to extend on that one and I will with Amsoil. The other one in two years. It’s already extended ( Toyota) I go 6-8K, they say 10K. After warranty I’ll go once a year or 10-15K with no fear with Amsoil. It’s a 4Cly non turbo engine.

So ten oil changes each and based on oil only. Well I can buy AMSOIL or Red Line for $10 to $11 a quart so for five quarts $50 to $55 per change or $500 to $550 a year in oil.  $280 a year for your $28 per jug example. Is that what you wanted to know?

 

If it, is it missed the point of using products like AMSOI or Mobil 1 Annual Protection for that matter. So lets try again using claimed numbers. 

 

GM 7,500 mile OCI's with any Dexos 1 Gen 2 oil. so lets keep the $28 a jug oil. Let's use 25,000 miles to keep us in even units as well for annual miles driven. 3.33 oil changes or $93.24 a year in oil. Let's use the "Market price of AMSOIL" $12 a quart or $60 a change which is also $60 a year. 

 

This argument is always left hanging in the wind of uncertainty of OCI. Both sides can win the argument with the right numbers plugged in. RIGHT!!

I do 3 K mile OCI's.

We all have our opinions and ways of doing things. I prefer short OCI's and use spec oil.

Buying better oil permits extended OCI's, I agree.

Doing short OCI's may cost as much as extended OCI's with more expensive oil.

Don't care about cost.

I just like clean oil so I change more frequently.

 

I have used off the shelf spec oil from a lot of manufacturers in a variety of vehicles without issues.

What does an oil blender mean when they say "75%" more protection?

(hint)

What point(s) of reference are they using for this claim?

Curious if you please. If fresh oil has a color value of 1 and the blackest oil you've ever drained from any motor is 10 what value would you give your oils color at 3K miles? Remember ARCO Graphite? Yea, that kind of black as a 10.
