Just wondering if you guys have any feedback on my latest report?!

Used the same oil as last time, Pennzoil Platinum full synthetic. Car now has about 36k miles and I change the oil every 5k miles.
Mixed use of city, spirited, and track driving. I VTEEEEEEEC the crap out of it any chance I get! Burns about a quart every 1,000 miles.

The time interval is what worried me a little. Over two years since the last oil change but the report seems decent.

 

I see nothing alarming even though my report at 58,000 miles had Copper = 1. AP2 engine but less than 3000 miles on an annual oil change. Royal Purple 5W-30 full synthetic.

You really had to replace 3 quarts of oil in 5000 miles this time and 5 quarts over 5000 miles the last time? 8 quarts in 10,000 miles? Ever let it run too low? Yeah, Honda claims that's "normal" but there may be better oils than what you're using.

Copper is elevated, that is pretty high when the typical levels are 1-2 ppms. Iron is also elevated. Have you ever run the oil low accidentally ?

Keep monitoring on the next interval and hopefully the levels trend downward.

 

Looks like 4 ppm is average for copper?

I really don't know how much oil I added, just guessing. But I do operate at high RPM regular and add oil regularly.
I've tried a couple different oils on my previous S2000 and they all seemed to burn.

I keep an eye on the oil level. Never really gets below the half way mark on the dipstick before I top it up.

 

That is Blackstone's estimate of average which is a bit off IMO. I would say average copper is 1-2 ppm's during a normal oil change interval, four is still acceptable though. Yours is double that so it is elevated, and whatever contributed to the elevated copper caused some extra iron wear too. Copper is bearing wear. No need to be alarmed right now, just monitor and keep testing going forward and see if the numbers trend downward. I had an engine with elevated copper just before it puked its bearings.

High rpm driving won't harm anything, what kills these engines and bearings is low oil levels, and it is made worse if you do any sort of hard cornering while oil levels are low. Your choice of oil is fine.

 

To my knowledge the Blackstone "universal" are not a true universal average just samples submitted to them. I have no clue how many samples are in their records. The averages for this AP1 engine are different from my AP2 engine's test last year. Some higher, others lower. The averages are dynamic, though, and give relative wear levels compared to other cars. Relative, not absolute.

Just to offer a point of view...

I've never been able to fathom the use of a UOA on an engine from a company known for making engines that just run no matter what you do to them.

there are probably millions of harshly driven Hondas with 200-300K miles on them that have never had a UOA....and they run just fine.

Some of them have their oil changed every 8-10K with whatever junk comes out of the barrel of the local lube and go place.

It just seems like people who keep obsessing are the ones who run into massive issues, as a direct result of their weird experiements chasing some special UOA number.

Why y'all so worried? About copper....
what even is copper??

 

Copper is a trace metal in bearings which, if present in the engine oil, can indicate the amount of bearing wear. Only reason for an oil analysis is to predict engine wear and possibly take corrective actions. We used to change the oil in our (Army) tanks by a time schedule ("or 12 months whichever comes first" type maintenance) and consequently dumped thousands of gallons of motor oil. The AVDS-1790 diesels held 21 gallons (not quarts) or 18 with oil change) of oil in the crankcase. The 159 tanks in my unit required the expenditure of nearly 3,000 gallons of motor oil every oil change -- and this is just for the engine. Once we started oil analysis we didn't change the oil until directed on an individual tank basis. And occasionally we'd get a message to immediately pull the power pack and sent it for rebuild.

You can do the same thing with Blackstone. Just pull the sample and see what they say about changing the oil.

For a car holding a little over 5 quarts of oil, though, the analysis is largely a matter of curiosity albeit detecting exceedingly high amounts of any metal can assist in pinpointing wear (or contamination) issues.

I literally have no recollection of when I changed the oil in my previously supercharged, 165K mile track S2000, or how much track time its seen since.

Circa 2019?

Did they even discover copper back then?


Anyway, I'll leave u guys alone.

 

I started doing the oil analysis after the main bearings blew in my previous S2000.
That one had three previous owners who didn’t care much about keeping oil in the car.
Makes me a little paranoid this time around.
