Results are in for Shell Rotella Gas Truck 0W-20 in a 2013 Honda Civic (1.8L, non-turbo)
From this earlier post I was looking for High Ca/High Moly oil:
https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/5250127/1
I arrived at Shell Rotella Gas/Truck. It was also on rebate.

Results are about in-line with prior results on Idemitsu Eco Moly.
TBN was quite a bit lower, but that did not affect wear metals. Probably couldn't go much longer, but I wouldn't want to go more than 8-8.5K mi anyway between oil changes.

I was spiking the Eco moly with a little ZDDP, so z/p were elevated intentionally. May do that on this current interval.
I used the Shell Rotella again, so will have another data point to report in another 6 months.

Any comments? This is a decently controlled experiment, so let me know if there are other suggestions.
Fortunately or unfortunately this engine is pretty robust so may be difficult for anything to look significantly better/worse.

You can go to 10K easy which is the factory recommended OCI IRC. There is a lot of life left in that oil. It's in the 20 grade range with no signs of oxidation. It's a boring UOA.


make the inside of your engine oil cap white.
don't use.

Did your Honda Civic grow a 6ft bed since you used truck oil?

Boring is good as far as UOA's go.

My FR-S sprouted a fold out tow mirrors, a stack, and goofy dished mud tires when I switched to RGT.

That's some serious Mo in that oil. Lot of test results I've seen Mo was usually in 70 - 130 range.

Yeah, i went and searched some other VOA/UOA and it should be about 160-170.
I didn't actually change the oil filter, but i wouldn't think that would affect it that much. Guess next oil change will tell.

Some of that moly could be residual from the Idemitsu. This thread indicates that Rotella has less moly than shown in the UOA.
