My first post here. I thought I would share the UOA for my beloved 2011 Honda CR-V SE fwd. I bought it new in late 2010 and so far it has been extremely reliable, rock solid (no squeaks or rattles), and is running well. I do all the oil changes myself at the recomended OCI indicated by the car's maintenance minder. I exclusively have been using Mobil1 0W-20 AFE + OEM Honda oil filter. It has been primary driven in town and plus the occasional weekend trips, thus the relatively low miles (58000). I decided to do its first UOA just to make sure there are no hidden problems with the engine. Looks like most values are close to the average, with the exception of lead, which is a little higher than average at 5ppm. Hoping this is not going to cause any long term problems since I plan on using the car at least a few years longer. Wife wants a Lexus in the future ;-)

I would be tempted to go with a 5W-30 PP oil change next interval if it was my car. See if it changes that lead number.
Make up oil added- 4.5 quarts over 8600 miles. Is that a typo ?

I'm guessing since this is the OP's first test that the 4.5 qts was the fill after the drain( it's the manuals stated refill quantity) and not make up oil that was added during the course of the OCI.

I might give that a try. I live in N. California where it rarely gets below freezing in the winter and the summers are regularly >100 degrees F, so I guess a heavier oil won't hurt. Nice not having to worry about voiding warrantees anymore.

Being a noob to UOA's, I thought "make up oil" meant how much did I add to the crankcase when I changed the oil. But yeah, it should be zero. I have never needed to add a drop of oil in between oil changes. Hope it stays that way, since I read excessive oil consumption is a problem with this generation of CR-V due to carbon buildup on the rings.

I don't understand why Blackstone said it was high.
I agree, it's bizarre that they would think that's a high number

It could just be some debris or dirt stuck in the bearing and it will work itself free. I would do another UOA around similar mileage with the same oil and see what happens to the number.
That ppm is nothing to worry about unless we see it get worse and worse in the trend.
Also...
to BITOG.

Blackstone has a habit of basing all recommendations off that sample's specific engine family's universal averages... so when this sample was 400% higher than the average, that is "a little high". If OP's engine was a 350 Chevy, they would likely be commending the excellent shape his engine is in!
Nice report, and welcome to BITOG!

So if this is the case, then a thicker oil is definitely a poor suggestion.
You need as much circulation through the drainage holes as possible, and the thicker suggestion is the opposite of this.
Just saying...
You have posted an excellent UOA and there is zero reason to change from a formula that is clearly working quite well for your service conditions.

The excessive oil consumption is caused by using poor quality fuels, and high rpm/load before engine fully warming up (per Honda). As long as you use top tier fuel and let your engine warm up before romping on the gas, you should be ok.

Universal Average for that engine for lead Pb is 1 ppm, and he got 5 ppm. Nothing to really worry too much about. Way above average which like it's been said above, might mean some Pb is leaching out from scratched babbit material in a bearing or two. Using a 5w30 or 0w30 (M1 AFE 0w30 is about the only one with in GF-5 flavor) would work just fine here.

Use https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4230933/Re:_Valvoline_Premium_Blue_Res next summer. It's a little thick, so summer only. Eats carbon off ringlands. Use one in 70k or 100k miles or so.

Using a different oil with different formulations is what I would look for is another reason I suggested PP. PP may counteract that oil control ring concern.

I'd be surprised if this engine had tri-metal bearings with lead in them
Many marques had long switched to bi-metal at this point.

What evidence is there that PP does anything more for cleaning ringlands than anything else, except Valvoline Premium Blue Restore (VVBR) of course, which is purposely formulated for just that effect? If anything, the high POE in Redline would get you cleaner ringlands, which is part of the patents and IP the VVBR is known for. .... PP is no better for cleaning ringlands than any other dexos1 Gen2 oil on the market, according to any evidence, which should count in a discussion.

I've wondered that too. Might be the last year for lead in Honda bearings. ... I think, not sure of what all things in the universe use though, that bearings went to aluminum babbit and/or backing en masse at around 2010+, which makes this CRV one of the last lead-copper-tin bearings. And if not aluminum, the stop-start engines went to polyamide imid or similar polymer-aluminum bearings (i.e., Corvette 2014+).

This is one of the many reasons I chose Pennzoil Platinum 0w20 to run in my Accord.

on both points. If the engine doesn't have tri-metal bearings and instead aluminum, then the lead isn't a product of wear inside the engine and can be ignored. Similar to seeing it on a Ford Modular, which have bi-metal bearings with no lead.
