World Wide oil recommendations for 3.7L engine
As many of us know, the 3.7 L engine is known, at times, for oil consumption issues. My own uses 1 QT per 2K miles but some use much more. I have been doing a bit of research and in looking at the oil recommendations for this engine in the UK and Germany, the recommended oil is quite different. Could it be that the 5W-20 recommendation for US models is less than optimal? I have used synthetic 5W-20 since removing the break-in oil.

Both 5W20 conventional and 5W20 synthetic oils exhibit the same viscosity under normal operating conditions, except under extreme heat or cold; thus it will make no difference in terms of preventing the oil consumption issue.
Since it is the piston rings that are the culprits, one can try using thicker oil weight, such as 5W30 or 10W30 oils, because heavier oil has less tendency to slip pass the sealing piston rings.
However, the factory only recommends using 0W20 for FWD and 5W20 for AWD TL's, so using a different oil weight might give Acura an excuse to void all engine related warranties.

Honda used to use 5W-30 and now it's down to 0W-20. Honestly, pick up some Mobil 1 High Mileage 5W-30 and it should help out the oil consumption. If it does, stick with that or move to the european 0W-40.

At what mileage is a car qualifies as high mileage ?

Shear stability is a measure of the amount of viscosity an oil may lose during operation. Oil experiences very high stresses in certain areas of the engine such as in the oil pump, cam shaft area , piston rings, and any other areas where two mating surface areas squeeze the oil film out momentarily.
Most multigrade engine oils contain special types of additives, called Viscosity Index Improvers, which are composed of very large, viscosity-controlling molecules. As the oil passes through the engine, these molecules are permanently sheared or torn apart over time, causing the additive to lose its viscosity.
Hope this helps

^^^^^
In that case, if high-mileage engine oils will provide better shearing protection, does it mean that all brand new cars (not just old cars) will also benefit from using these high-mileage oils for better shearing protection ?

Yes, the high mileage name is a sales pitch; look at the formula and compare with Mobil 0W-40 European or some Boutique oils like Redline and compare Phosphorus and Zinc.

Wow 1 QT per 2K miles!!!!! I thought that my 2012 TL SH-AWD was consuming a lot of oil. I currently have 30,000km (18641.1mil) on it but I have to add 1L=1qt every 12000km (7456mil). I do only use acura fully synthetic motor oil 5W-20. I am not sure if it is normal or not???

"Excellent overall lubrication and wear protection. Outperforms our conventional high mileage oils."
"Mobil 1 High Mileage oils are suitable for many types of severe driving applications including high speed highway and stop and go city driving."
And sure, if oil consumption is excessive (Like you mentioned: In case piston rings are the culprit) no matter which oil, none will resolve the problem.

Higher viscosity oil will always help if minor piston-ring sealing is the problem, because heavier oil won't get past the sealing cracks as easy as lighter weighted oil.
However, higher viscosity oils, such as 10W30 or 10W40, are not recommended by the factory for the TL sedans.

Nevertheless there is more in play than higher viscosity oils; additives (Viscosity Index Improvers) might be beneficial and compensate without having problems with manufactory warranties like M1 5W-20 HM
I like to try different oils; right now I’m using Redline 5W-20 - My 2011 TL SH-AWD does not consume oil regardless which oil I’m using Mobile or Redline.
I already mentioned in other posts that I’m not going by the MID – I change oil and filter between 3000 and 4000 Miles. Some might say its overkill.
For 50 years I checked the oil dipstick on a regular base no matter which car or what technology used. I’m an old guy and old school; I always changed oils before the recommendation of the car’s manual, maybe I was lucky for 50 years no problems, average mileage per year 35000 miles.
Oil is cheap; engine problems are annoying and expensive.

I am currently driving a 2010 TL SH-AWD. Since I purchased it last August I've only used M1 5W-20 synthetic oil and I've noticed that when I reach close to 40% of oil life remaining my car had burned quite a bit of oil since the last oil change. Twice now I've gotten the low oil message
. And I also noticed that at WOT throttle, it starts coughing somewhere between 6000 to redline and I can smell, what seems like to me, excessive fuel being burned. This coughing was always resolved by adding additional oil. I have just recently started using a 5W-30 high mileage synthetic by Penzoil. I'll let you all know how that works for me at my next oil change. So far I have noticed that the car runs a little smoother and just ever so slightly, a tad bit sluggish. I also did not notice that weird fuel smell at WOT
. I hope this information sheds a little light for someone.

^ The stumbling is probably caused by the fact that there is insufficient oil in your engine to operate the VTEC transition mechanisms properly. If the engine is that low on oil, that is a big problem. A little lower and it probably would have gone into semi-limp mode, i.e., the engine wouldn't rev above about 2500 rpm.

5W-30 Test
So here's a quick update from when I switched from 5W-20 synthetic to 5W-30 synthetic. So I did a 3x3 tranny flush last week and I decided to check my engine oil and lo and behold, there wasn't any oil on the stick -literally nothing
!! As if the engine were new and never had oil in it. I am about 5,500 miles in with 50% life remaining. I refilled it with Penzoil 5W-20 for the remainder of the oil life monitor since I will deploy here next month for 7 months.
I used 5W-30 fully synthetic by Penzoil coming from 5W-20 Mobil 1. Let's just say that both of these are off my list.
