Just thought I would share my first oil analysis. this is the first oil change I did going to the Rotella T6 5w40 running Rev-X with a Amsoil oil bypass setup. Think I will try the Archoil next time around. I would have went with it this time, but I already had the Rev-x.

On that note, when the engine is cold, I have a miss problem pretty bad. I feel I may not have gotten to the injectors in time before the FICM started going bad. If I plug it in no issues, let it warm up no issues. Nice and cold nice miss under acceleration.

Yeah, well what I am thinking, is this truck as been running dino oil, and this sample was off the first time this truck has had had a synthetic oil. I am guessing with the Rev-X and the fact that synthetic oil is such a good cleaner, that the next time i do the analysis which I will pull at 5k, well go down. Or I hope anyway. I have reviewed several reports and everyone seems to lower than me, but also seems a lot of people have also been running the synthetic oil longer than I have. I only know this truck has been running dino oil as I found receipts, and the log the previous owner had kept stated Rotella T 15w40. So i am the first to flush this thing with some synthetic.

Don't be so sure that the numbers are dino oil related. With 100k on mine (at time of oil analysis), AT LEAST 65k of that was Rotella T 15W40. That being said, at 10k on the oil, my iron was 16 my viscosity @ 100 was 14.5 and my TBN was 7.1. That was at 10,000 miles on dino oil. I also do my tests at Speedco.

EDIT: here's a copy/paste of my 10K dino oil numbers from Speedco:
Aluminum__4
Chromium_<2
Copper___<2
Iron______16
Lead______6
Tin_______<2
Silicon____<2
Potassium_<2
Sodium____12
Moly______4
Water____<0.1
Oxidation_5.2
Visc@100_14.5
Gkycol____ND
Fuel______<2
TBN______7.1
Nitration__<2
Soot_____0.3

I changed my oil when I sent the sample out. Then a week later I saw the report.
I decided to test but not change the oil when it got to 3,000 miles. Not a drop of fuel, and I have never had fuel show up out of the last 5 samples and 4 oil changes.
I think they messed up the test. Blackstone labs.


Im about 50 miles from 10,000 miles on 3 gallons of 10w-30 and 1 gallon of 15w-40 of rotella.
This is the same oil that I tested at 3,000 miles.

I will as usual post the test results.
