Used Oil Analysis Reports - 2nd Generation Tacoma

This is odd...On all the UOAs on my 2015 V6 Tacoma so far, the viscosity tends to shear down slightly..

 

Yeah, maybe it could be from idling when off roading for long periods, crawling along at higher rpms or something.

 

deezy - Very interesting - the latest UOA on my 2015 Tacoma V6 also shows a slight viscosity increase, very similar to yours!

 

Yeah, I'm thinking, in my truck, it's from idling for long periods in hot weather when we go on offroading trips.

 

Im just getting ready in the next couple days to change my oil and send a sample in, curious how it will show.

 

Funny seeing this..I just got my kit out of the mailbox a few minutes ago. Gonna try to get an oil change in before the white stuff comes down.

 

My report came back and Copper was the only thing slightly elevated but reading thru some of the other reports it seems fairly common for our engines.

 

My second report...even though Sodium is listed as a contaminant, it's also a common additive. I used Mobile 1 Extended for the first sample, and Valvoline MaxLife High Mileage the second. Used Mobile 1 Extended oil filter for both samples. Even though mileage was almost 1K less than with Valvoline, the TBN value was quite low compared to Mobil. Thus far, Mobil is looking like the better of the two oils. Replaced oil with Valvoline again, but with a Purolator Synthetic oil filter. Will change at 8K for this sample and then switch back to Mobil.

 

This is interesting, I just ordered a test kit and will see what I have next oil change. Currently my 13' DCSB 4.0 has 63k.

 

The latest analysis. I was curious to see what the results were like because my truck had been ran at the rev limiter for some time on multiple hill climbs.
All is good.

 

Looks good...what synthetic oil do you use?

 

I just use Mobil 1 5w-30. I buy it whenever it goes on sale at Costco.

 

I'm always interested in the Moly number when I look at my report. The number on yours is about the same as mine, I usually run either Pennzoil Platinum HM full synthetic or M1 HM. Occasionally WW will have Quaker State UD on sale for about 20 bucks, Ill use it but it's not my first choice.

 

Somehow have missed this thread in the past! Adding mine:

2015 TRD OR V6, Mobile 1 5W-30 Extended Performance Synth

I had asked a question in the comments as to whether I should worry about replacing the oil more frequently than mileage suggests since my truck is now very low mileage (less than 3K/yr)

 

Blackstone comments are well worth the price of the admission. Very insightful, nice to hear from the pros vs guys on here who think they know how long or at what miles/months one should change their oil.

 

2011 TRD OR 6spd, Mobil 1 Advanced Full Syn 5w30, 5,221 miles on sample.

 

2011 TRD OR 6spd, Pennzoil Platinum Full Syn 5w30, 5,211 miles on sample.

 

Oil!
