Mobil 1 5w20 9400 miles in Honda Civic Si K20A3

[Surprise]

Ok once again. I thought people would be interested in how a 20 weight oil would perform with long intervals over a long period of time under a more agressive than average driver. 7 samples of 7K+ miles, 4 of over 9K+ miles, 85K miles on car.
New sample is on the right:

I would consider the driving that I did on this OCI as very diverse. I had a few 350+ miles trips, 650 mile trip, daily
As seems to be normal, I am very happy with these results and plan to continue at 10K intervals. I think it would be pretty hard to get better results. A little concern on Fe however. Any thoughts?

Excellent report. I'd push it out to 13k miles.

 

[Titan]

It's obviously going to blow up soon since you're running such thin oil.

 

[theedge67]

I wouldn't be concerned about 12ppm iron in 9K miles. Divide that in half and you get 6ppm per 4.5K miles. Do you like the number 6 better?

 

[Lonnie]

Two things. One, your reports show consistency, good.
Two, your columns don't line up, bad.

 

[ThirdeYe]

Looks really good to me, I thought the Iron was out of line at first until I saw how long the oil was in service. I'm assuming by the mileage that this is the EP3 Civic Si, right?

 

[Cutehumor]

looks good, I like how you posted all your UOA's in a row. good to know, some didn't jump off the mobil 1 ship

I kept trying to back off of the screen to see if it formed some kind of art work if viewed from afar.

"~30+ Auto-X runs"

?????

Please explain

 

[wantin150]

Auto-X = Auto Cross Courses = "extreme" conditions

 

[Surprise]

Hopefully the image hosting site will allow the image to be seen.

This is what I see on my computer. The only column that is not in correct location is the make up amount. Looks pretty easy for me to read.

ThirdeYe:

Yes this is a 2002 EP3

TooManyWheels:

~30+ Auto-X runs is a little redundant. It means that I have donw approx. over 30 Auto-X runs that consist of a short timed course made out of cones. Pretty much WOT and brakes for about 50 seconds.

My eyes played tricks on me. I thought you were referring to a sludge removing product!

I've known about autocrossing all my life, and done my share.
