As you can tell my MPG of this round was much higher than the last, my driving went to mostly highway mileage blended with a lot of traffic. The gearing in my car places my engine at 4000rpm, probably not the easiest of rpm range. No auto-x in this range, but a decent amount of WOT and ac use around town. No fuel or oil additives.

I am not the happiest with the trend of the lead and iron. I think this next interval I will go to 7500 mi with the M1 5w20 that I put in it this time. Maybe 5w30 should be in my future? Any thoughts?

 

[JavaMan]

My thoughts are 5000 miles will be my limit regardless of the oil I use in my Civic.

 

[Ugly3]

Changing labs and filters "muck" up the numbers a little but I don't see a strong negative trend in the numbers. They are all so small the the differences could well be within lab tolerences.

Overall, I would say these are very good reports and that maybe 5w30 performed a little better in terms of wear metals but not significantly.

 

[JavaMan]

nevermind

 

[JavaMan]

So, sorry. I really don't know what happened.

 

[benjamming]

Please explain to me the two filter rows. Which one is the oil & which one is the air?
I assume the top-up oil was the same 0W20?
Are you using any fuel or oil additives?
Mostly highway miles?
I do like the way you have presented the report.

1. It is only the oil filter, ie Honda branded fram, honda branded toyo-roki, honda branded filtec.
2. same oil type top-up
3. no
4. mileage wise, yes

 

[zoomzoom]

I think your numbers look pretty good..I would stick with 5W-20 and 10K intervals.

 

[PandaBear]

I would agree, 6 vs 9 on Fe and 3 vs 11 in Pb over a change in driving habbit, filter, and lab can change that. I would say 10k OCI is good also.

However, between the last 10k and this 10k it seems like the oil had beefed up in additives, but the insoluable increased. I'd say the Fram filter is to blame and you should stick with Toyo-R (S2000 filter if you want to buy without worrying about which one to get or hunting it).

 

[TooSlick]

Bearing wear is directionally increasing the SAE 0w-20 - it's simply too thin.

I'd go up one SAE grade and run 10w-30; given the CA climate. I'd also reduce the service interval by 20% and these numbers will significantly improve.

 

[Jay]

I'm perplexed by the high lead numbers also. In my RSX, I've never had more than 2ppm on any of my 7kmi tests with 20-weight and typically the Pb is 0.

You may have the right idea about shortening your OCI interval. Blackstone shows strong TBN at the longer intervals, but WearCheck shows M1's TAN as slightly elevated after 7kmi in my RSX. I've never sampled at a longer interval. Your own testing shows that Pb is getting out of hand on the longer intervals.

I'm getting better reports with Havoline 5w-20 and Valvoline Durablend 5w-20 than with M1. My iron was cut in half using these oils over M1.

Thanks for the reports.

 

[buster]

11 ppm of Pb is nothing. It could be better, but it is well below normal. Fe is excellent.

 

[Surprise]

My driving habits in this run have changed due to living in in a new house. I now live less than 1 mile away from the on-ramp to the freeway that I used to go to work. Often the engine coolant is barely 1/4 up the temperature gauge when I merge onto the freeway. I am thinking the merging onto the freeway with a cold engine would have this negative effect on the oil.

Could this conrtibute to the not so stellar numbers?

 

[Jay]

I don't think so. I "merge" into 60mph traffic right out of my driveway at home then go uphill! I cringe everytime I do it, but it doesn't seem to hurt my wear numbers.

Have a look at some of the other Honda 4-cyl engine reports on the forum and see if you need to do anything other than shorten your interval.

Ted,
Why would you think that the oil is too thin based on his lead trending upward? Wouldn't the lead just go up at least by the 2nd interval? I can't understand why this would be such a long & gradual process.
