This ole thread was an entertaining great late night read.     It spanned 3 years and the discussion was lively, and at times, testy, as most oil threads are.    The topic about "t

Yes, they can go sideways.  But, if people keep it respectful, these kinds of technical discussions on forums can be some of the best threads for revealing things to the layperson.

Does that include the dry sump?

The base Corvettes of this generation are wet sump.  Just like the trucks.  Dry sumps only come on some of the higher option packages.

If you wanted to order a replacement engine ... There would be only one part number for a 6.2 replacement?

Use what the oil cap says and manufacturer says Unless you know something they don't.

I've had better conversations with brick walls.  "Replacement engines" come with some parts I listed as different.  So no.  If you're building one, same block, heads, crank, rods, pistons, valves, cam, lifters, pushrods, valvesprings, oil pump, AFM garbage, etc, so yes for all internal parts.  Same part numbers.  How hard is that to understand?

I got it man...The same.
 

No, you likely don't.  And don't understand WHY GM recommends a different viscosity (emissions).  GM sells a lot more trucks/SUV's than Vettes and Camaro's...which somehow the Camaro gets the same motor but left out of the discussion.

It is not safe to assume that a higher viscosity oil is always better for your engine because other factors, such as engine design, fuel economy and power, are also related to operating viscosity. You should always consult your owner's manual for the right oil to use for your particular engine.

I read the entire thread and your statement.  What's on the cap is for GM to meet corporate fuel mileage goals and not necessarily what is best for the engine.  Do you understand?

Please contact GM and let them know they are not doing what is best for their engines!
Obviously they don't know what they are doing.
What weight is correct? I don't want to blow up my engine because GM told me to use the wrong oil!

You are too dense to get it, but I'll respond for those that might read your drivel and actually think it is meaningful.

- No, 0W20 won't blow up your engine.  

- Yes, 0W20 in a number of use cases may INCREASE WEAR ON YOUR ENGINE

- No, that wear will not likely cause an issue DURING THE WARRANTY PERIOD.  You know, the timeline GM actually cares about

 

If for a second you don't think GM would give up 50k miles of average engine life to bump their CAFE rating 1/2 a point, you are just plain nuts.  It's smart business. 

 

Why is GM suggesting a different weight for what is basically the same motor on their performance cars?  Cars that are much lower volume and don't impact the whole like their bread and butter trucks/SUV's?  THINK and respond, don't just respond.  THINK as to why they would do that.  Use logic and reasoning, not "because it says so on the label."

Plausible but not proven.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Actual Full Screen CarPlay on Refreshed Silverado/Sierras.

      By Greg3160 · Posted

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
