No midway filter change anymore. I've been running straight 12k on oil and filter as long as you can see on the report. Early on I was doing a filter change, but there is no evidence to support this method being better than leaving the filter alone. I use the YZZ filters from Toyota/Lexus, not the IS-F specific filter and regular Mobil 1 5w-30. I am a bit disappointed in the formula change in Mobil 1. You can clearly see it in the calcium and magnesium results where the numbers changed dramatically. This is the first time I've suffered low viscosity though. I really don't want to change brands, but if I keep seeing this kind of viscosity issue, I might cut my OCI back to 10k.

Thanks Lance! I've been doing 5k on the mobile 1 and factory filter. I'll give the YZZ ones a shot and try it for about 10k next. Do you know anything about the mobile 1 extended use? It says guaranteed to run to 15k miles. Do you think there would be any benefit over standard mobile 1 if running the extended use one to about 10-12k miles? Its only a few bucks more per 5qt container at walmart.
in place of the drain plug, so I can pull samples any time I want. I might try a sample at 10k just to check the viscosity and see if it is degraded at 10k too.
They only add a little more zinc to the extended use stuff. I don't and won't run it. There is no need when I am doing UOA on every oil change.
This last change I installed a Fumoto valve in place of the drain plug, so I can pull samples any time I want. I might try a sample at 10k just to check the viscosity and see if it is degraded at 10k too.
Thanks for the info! Post up your results if you end up doing it at 10k Thanks again!

I love Fumoto's and have them on several vehicles. Mostly on diesel powered cars/trucks we own for sampling purposes as well. One will go on my F I am sure at the first change.
I haven't had the opportunity to peruse the Fumoto site, but am I correct to assume the F106N (or 106 if you happen to prefer nipple-less) in the link is correct for the F?
Blackstone has enlightened me on the true content of my oil for a lot of years, everything from blown big block Chevrolets to 6.0 IH/Navistar diesels, definitely money well spent.
Bought my 08 in May of 14 with 39k. Performed my first oil change at approx 44k, unaware of what oil was used before, but it wasn't synthetic. Moved to Mobil 1 and plan on staying there. Here's mine, lookin' good so far!
WOW this is pretty cool stuff. A little over my head but as long as I track mine as well and all seems ok with the rest, I think I can sleep at night knowing Im ok.

Shouldn't the sample be taken midway through the full oil drain/stream for the most accurate results? You've gotten quite a few of these and me only one, just checking on your thoughts on this.
edit: Me for example drained approx 5 quarts before I captured my sample.

The key is, don't take a bottom sample. Let it run a few seconds first. I've taken samples from the filter housing and from the drain plug (when I was changing the filter at 5k miles). There no indication either is appreciably different.
Did my 2nd oil change and here is the report. First sample is factory oil, changed @ ~3500miles and second sample is Amsoil 5W30 with ~6000miles.I will most likely go 8000miles before the next change.
Actually your fuel and our fuel are pretty close to the same. Your octane measurement is different than the US method, so the numbers are higher, but if you use the same methodology, they measure out to be nearly identical. The thing to look for in your fuel is called sensitivity. It is a measure between motor and research numbers (your numbers are research, not motor, ours are (R+M)/2). Sensitivity can vary dramatically from brand to brand depending on the components of the fuel.
There's a pretty long discussion called the gasoline FAQ by Bruce Hamilton. It's a bit long in the tooth now, but the fundamentals have not changed in a very long time, so it's a really solid read if you want to understand the hydrocarbon cocktail you are feeding your precious one.
In the real world, the only thing an engine builder cares about is the motor number. It is determined using an engine under heavy load, so it best replicates the conditions a competition engine must survive.
But none of this has anything to do with oil service life. Ring fit and the resultant blowby, average drive cycle time, and typical atmospheric conditions where you live have a lot more to do with your oil's service life than anything else.
