1 Year, 17,400 Mile Oil Change Lab Results

Buzzbomb · #1 (**permalink**) 08-18-2009, 01:40 PM

My results finally came back so I thought I would post them up.

To recap, this oil change consisted of 5w-30 AMSOIL w/ the AMSOIL Ea oil filter. A half of a quart was added at 13,000 miles.

The test came out good, but my silicon (dirt) level was high. I'm not sure what to do since the airbox is 100% stock. I'm not overly concerned about the aluminum at this point since the PPM/Mile ratio dropped from the last sample.

My TBN checked out OK as well, but it's about as low as I'd want to get it. 2.0 is my absolute limit.

The car now has 0w-30 AMSOIL w/ the AMSOIL Ea oil filter. I'll probably send in a sample when it's time to change the oil, but I won't do any in-between.

Enjoy!

That's crazy you went a whole year without changing your oil, cool stuff.

Sweet - all looks good to me. I wouldn't worry about the silicon if I were you, I'm not exactly sure what they're talking about in the comments section. Do they know you didn't change the oil from the last sample? I mean, 18ppm vs. 16ppm 5k miles ago is hardly anything. My oil report showed 6ppm, but that was for a paltry 3,700 mile interval. Extrapolate that out to the mileage you've put in on your interval, and it's quite a bit more than 18ppm.

Thanks for sharing!

Interesting, this is the first time I've seen oil analyzed like this.

Mind if you can share your driving conditions for the 17,400-mi interval?

Sure,

28 mile drive to work, one way. Mostly highway. I drive through a couple of small towns with stoplights.

I had 2 auto crosses on this oil change as well.

Weekend driving consists of city driving with moderate stop and go.

Yeah I guess you're right, the dirt/mile ratio is pretty low. I'm not going to lose any sleep over it, that's for sure.

curious what the 0w-30 oil would look like.

After I took a sample at 13,000 miles I pulled the dipstick and saw it was a little low. The sample is only 2 or 3 fluid ounces so I had to have burned a little. I pulled the dipstick again before I changed the oil and it was still full.

It was the first time I had to add oil. but the car only has 23,xxxx miles. I didn't add any during the break in period. We'll see what happens during this new run.

It should be very similar, though you'll have to wait a whole year though!
