Hm, I am guessing you didn’t reference the original sample’s fluid time, viscosity and wear metals.

Air filter was changed shortly after sample 1. Fumoto valve was installed after sample 1. There have been a few oil changes in between. Certainly could have been contaminated from something to do with the air filter or the visibly dirty Fumoto valve. Not at all concerned. What Javier said is...

Considered the euros but with this report I don’t think I’ll be changing anything. Also happy with 4k in the winter. Regular hybrid, ICE is involved in every drive. I have a mighty vac but havent tried. 11ppm of iron per 1k miles with 0w-16 and measurable bearing wear metals vs 1ppm of iron...

I’ll clarify: I’m suggesting the silicon contaminated the sample, not that silicon was in the engine. Air filter has about 10k miles on it. I saw dirt on the valve it and tried to clean it. Waited about 30s of flow to get a sample. I may reach out but it’s not going to change the particle...

Here’s my second UOA on the vehicle. Oil Analyzer’s thinks this is M1 0W-16 again but it’s Valvoline Restore and Protect 5W-30. Stepped up viscosity due to severe fuel dilution from the cold, short trips and the nature of the hybrid. Sticking to this interval for the winter months, planning on a...

I have a 3.0 Duramax, have been using M1 ESP x2 0w-20. Doing roughly 4k mile OCI. I only use 0W-20 to keep the warranty intact. From the iron numbers I see on UOAs and how hot this oil gets in these motors I’d personally want something thicker. The Mobil 1 is a relatively thin XW-20 and there’s...

I wonder if our driving conditions differ. Of the 2k miles on the oil, i bet around 25 percent have been while the oil was at full operating temp. I had not noticed any signs of fuel in the summer where we do much longer trips and it doesn’t frequently have to start at 0 degrees or less. You’re...

They wrote a nice reply: “Samples are retained for 30 days. Unfortunately, we would not be able to have the sample retested at this point. However, you would be correct in that Zinc and Phosphorus are too high for what’s allowed to meet API SP requirements. These levels are limited to about...

Reached out to the lab, they only hold the sample for 30 days.

Car says low 30s during winter and high 30s during summer. Hand calculations have always showed 2-4 mpg less than the cpu. Didn’t even notice the soot in the report. If it was at diesel levels, wouldn’t it be jet black? Oil on the way out was as clear as the day it went in.

Finally, someone mentions the pun.

Pablo, yes M1 0W-16 is what was in prior. Tex, thanks for the input, that pretty much my line of thinking. #18, good idea with the plugs. Joe, yes this thing runs very cool in town. I’m still shocked by what this shows for an addictive pack Here’s tho ones that stood out to me compared to a...

I should have mentioned this in the original post - it is the hybrid. Also, I did not expect the high calcium and zinc. Pablo, it just shows greater than 5 percent. I am mostly concerned with iron and lead levels after such a short run. And the powertrain warranty will be done by mid summer so...

Hello all, Looking for advice. Here is the only UOA I’ve done on my wife’s 2020 rav 4. We purchased it with around 30k miles on it. I started to notice an alarming rise in the oil level (smelled fuel-like), decided to dump and get a sample. I estimated an additional 1/4 - 1/2 qt of fuel. I...
