Oil Analysis 2UZ-FE

Just heard back from Blackstone regarding the sodium level.

"That is a very good question, since sodium can show coolant contamination in used oil. The oil you used was Valvoline Synpower, which we know contains this amount of sodium as a harmless detergent/dispersant additive. Without any potassium present (another marker for coolant) and with wear looking this good, we are not concerned about coolant in this sample."
 
Good to hear and as usual Blackstone is not afraid to look into things further if needed. Thanks for sharing.

Not to mention Water % and Antifreeze % were both 0.0. Agreed, Blackstone provides great customer service and feedback. Seems like I continue to learn something new from them from time to time.

I was a little disappointed that I ordered bottles from their website tool, and they didn't show up in time for my maintenance routine (but I just filled a small mason jar and capped it with cellophane in the mean time) - I called them to ask what happened and they did not know, but they took my bottle order over the phone and were very friendly and polite. For all I know, I messed up the web form...
 
worst 2UZ UOA ever?

I intentionally did not change the filter during this 10k mile interval, I wanted to see if everything would look acceptable following 10k on only one filter. Metals are a little higher than I expected, I will definitely change the filter twice on the current 10k interval, and then re-analyze the oil.

Some background, I purchased the truck with 122k miles and changed the oil and filter (Mobil1 and Napa Gold), changed oil and filter again at 125k miles, changed oil and filter again at 130k miles. The current analysis was for the 130k to 140k interval.

This analysis doesn't seem as good as others I've seen on this forum. But the guys at Blackstone didn't seem too put off by it, so I'm not going to worry much, especially if the next report has lower levels of metals. The TBN is right where I want it after 10k miles ;)

Just got my oil analysis back from Blackstone. It didn't look so hot. 10,000 miles on M1. Used a crap Fram filter which I didn't replace. I have switched to the M1209 for this interval and am going to go 7K miles. The result was a bit unexpected and a bit scary. I hope between a good filter and a lower interval the next one will be fine. If it is, I may increase the interval again with the good filter.

If you want some good feedback, post up on bobistheoilguy.com in the UOA section. I don't think your results are bad or concerning.
Use the yota -20004 filter from now on.

^ will do thanks!
 
Jon, did you capture the flow mid-stream or was it perhaps the initial dump that could be sediment-heavy?

And at the risk of re-opening a huge debate... the saying goes "a quart of oil and a main bearing cost about the same, one is just a little more difficult to change than the other". 5-7k intervals seem like the happy pint to me. :popcorn:
 
a critical equation with the use of synthetic oils is ALSO using a high quality particulate filter that will capture suspended particles and not allow them to recycle. I would try a Mobil 1 or Wix filter.....and change at every oil change especially the first couple times you run synthetic in case any sludge is pushed into filter due to natural cleaning action of synthetic on an engine.
 
changing only the filter is same deal as changing it at the same time as oil change. All the oil is in the pan, just begin to unscrew the filter, let the oil in the filter drain out some, then continue. I always fill the new filter about 3/4 full before I screw it on so there is some lube ready for the first start. But the residual synthetic oil in the engine should provide decent cold start protection even if the filter is not full.

Yes I captured the oil midstream.

I think a 7K interval with the good M1209 filter will be a good starting point. I'll post back up next year. :)
 
Just got another analysis done. I used the same 5w-30 Valvoline Fully Syn. This time, I used a K&N Filter. The results are good. There were a few line items that showed a tiny bit of increase. The sodium level relatively stayed the same (but a bit high), which Blackstone said it was due to that particular oil. So next time around, I am going to try Amsoil. I will also switch back to WIX filters (NAPA Gold).

Also of note: This rig is used by my wife as her daily driver. So there is lots and lots of stop n go, ultra short trips, etc.

^ Can you fix your photobucket links or attach the photos directly? Just sent the next batch in went waaay over what I wanted due to busyness and lazyness, 12,481 miles. Should have it back in a week or so.
 
^ Yes I have! Here is the report. I'll be the first to say I was lazy on this interval and never intended on a 12K mile interval. I plan on changing the oil at Blackstone's recommended interval and sending it in for analysis again. It's interesting because most of the numbers are lower with the exception of Aluminum, Copper and Iron notably. I don't know what to make of it. I clean my air filter religiously but do travel in extremely dusty areas.
