EDIT: No top-off oil added. The car doesn't burn oil.

.

I just had my Insight oil analyzed. This is one of the best oil analyses I've ever seen. I'm extremely happy.

I was surprised the wear was so small, because I frequently redline my engine, so I expected a lot more internal damage/wear.

Amsoil XL 5W-20(old full synthetic formula) - ~7500 miles
Insight - 27,621 miles

WEAR METALS (ppm)
19 copper
11 iron
0 chromium
5 aluminum
4 lead

OIL ADDITIVES (wear prevention)
30 molybdenum
862 phosphorous
1116 zinc
354 magnesium
2463 calcium

CONTAMINANTS
0.0% antifreeze
0.0% fuel dilution
0.0% water
10ppm silicon (dirt)

USED OIL PROPERTIES

83 sulfur
16 oxidation

Looks good. I'm not sure what to make of the loads/etc put on these engines.

How many total miles?

I am pissed that Amsoil weaseled and went Group3 with these oils. Maybe your best bet would be to switch to the 0/5W-30 full synthetic.

(scratches head) Please go back and re-read the post. It says "how many total miles" and also says "Original full synthetic formula". Thanks.

P.S. I was wondering what you meant by "load on the engine"? The Insight engine is 73 horsepower moving 2000 pounds.

And, I don't want to use a 30 weight oil. The Insight demands a 20 weight oil.

Did you by chance use another brand oil for top-off during the interval ? There's moly in the analysis from motor oil or wear element .

Also what going on with the phos ? Seems low for the amount of Zn . Here's what is left of the same oil ran in another engine .


Oil Additives:

Mg, 300 ppm
Ca, 3028 ppm
Boron, 0 ppm

P, 1244 ppm
Zn, 1387 ppm

OOPS me big doofus - missed that line - 27,621 miles (going too fast or looking for "total miles")....._thanks.

I know you wrote original syn. XL 5W-20, but unless you have some stashed (that would be smart) Amsoil doesn't make it anymore. The XL is now a Group III oil, an OK oil, but not a true synthetic.

I suspect the Mo came from a previous oil or???

As for load, thanks for posting power and weight, but I was also thinking about loads when transitioning, restarting, etc vs. a standard IC engine car.

Nice report. I'll say this though, your better off buying the ASL 5w-30 Amsoil for the money and getting a full synthetic. This engine is one of those low wearing engines and will show low wear for almost any oil.

Pablo, I was told by a local direct jobber that Amsoil will be bringing out a fully synthetic 0w-20 in about a year. The guy was nice and had some good info. to share but he also had quite a bit of BS too so I don't know.
 
Tin = 0 according to the report.

The Amsoil XL is ~2 years old. I purchased it *before* Amsoil changed the formula, so it is the full synthetic stuff. Still have about half a case left. ;-)

5W-30: WHY? Honda says use the 20 weight. Why would I want to use an oil different from Honda's recommendation? Sorry, I just don't understand.

20wt oils are all about CAFE, or fuel efficency. You don't have to run a 20wt oil in the car. I think even Ford's are now allowing 30wt oils that won't void the warranty.

Oh, okay. Well, that's why I bought the Insight! For fuel economy. I'd run a 10 weight if I thought I could do it safely and improve my MPGs.

Could the phosphorus have been used up by my frequent redlining?

Moly is bad because...? The only other oil was Honda's break-in oil during the first 2000 miles.

And during acceleration, the load varies. At 500-2000rpm, most of the load is on the 13 horsepower motor. At 2000+rpm, most of the load is on the engine. Here's a graph: http://www.insightcentral.net/encyclopedia/enperformance.html

Moly isn't bad, amsoil just doesn't use it in their oils. There is nothing wrong with a 5w20, as long as the UOA's look good. This oil seems to work well for you, but when you use your stock up, then I would switch to something else, before I would buy the new GIII XL series.
 
Hmmm... wonder where the Moly came from then?
And my current supply of AMSoil will run out at 70,000 miles. I planned to switch to Mobil 1 at that point.
 
Honda's oil = 0-2000 miles.
Amsoil = 2000-now.

I did not top off with anything, but I suppose it's possible the dealer added some Honda oil during the last change. But why??? He returned 0.4 quarts of left-over Amsoil to me.
 
After I looked at the other Honda Insight analysis you posted along with Virgin and Used oil analysis's of the Mobil 0/20 that have around 70ppm of moly it sure appears the Insight engine has coated pistons from the factory at this point in the topic.
If you have prior analysis's of your motor it might show Mo to be elevated above this sample as the engine broke in .

Are there other Insight engine oil analysis's available that you can post ?
 
If you use an oil that contains moly, some of the residual moly will show up in the next 1-2 oil analyses, although at a reduced concentration. I see this all the time and so does everyone else on this board - even if they don't realize it. Several of these Japanese 0w-20/5w-20 factory fill oils contain several hundred ppm of moly ....

Amsoil went to GP III basestocks since these work just fine for 7500 mile/6 month drain intervals, and the GP III basestock cost them perhaps fifty cents less per quart than a 4 Cst, PAO from Mobil or Chevron. It would make no sense at all to sell an XL-7500 Series formulation that costs the same as their 25k/1 year formulations.

The XL-7500 series oil I used was the original, unlicensed, GF-2 formulation that came out about three years ago. So the add pack is much different from what was used here.

Lead wear is only about 0.6 ppm/1000 miles - so I see no benefit in going to the Amsoil 0w-30 or 5w-30 at this point, unless you want to double this drain interval.
 
Well since this is the first run with amsoil, then that explains the moly, as Honda's breakin factory fill oil contains a crapload of moly (several UOA's posted).

It isn't his first run with Amsoil though. He ran the factory fill from 0-2000 miles and has been running Amsoil 5w20 ever since then. I'm not sure how many intervals worth, but I would assume he's done at least 3 or 4 since then, so the moly should've been long gone by now.

The moly from the previous oil is long gone . It's the piston skirt coating applied for use in this engine series showing up .
