Hello,
This is the second part of my post (see Silverado 1500 UOA post for part 1).
Below is the UOA for my 2007 Tundra 5.7L. I am more pleased with the Formula Shells performance in this vehicle, but am still wondering if there is a better option. My tundra is my work truck and depending on the time of the year it is pulling a trailer 50-75% of the time.
Something else I am wondering is it the viscosity of the 5w20 in this sample looks similar to the 5w30 in my previous post - to simplify things could I get away with using 5w30 in both vehicles?
Thanks again for your input/opinions.

TBN 1.7
GARTH: You've got almost 7,000 km on this oil and it looks like it can easily go longer. That's a testament
to both the engine and how it's operated. You must have a gentle touch with your Tundra. It looks great. The
TBN was still okay at 1.7. Some people wouldn't go any longer with this TBN reading, but we think anything
above 1.0 is still okay. Besides, the goal is to get as much use as possible out of the fill, right? So we'd try
8,500 km next to monitor. Universal averages show normal wear from this type of Toyota after 10,000 km.
No fuel/coolant found.
