MOA 115

I recently had my 2024 Silverado Trail Boss with the 6.2L V8 engine recall (L87). The GM dealership had it in for a day and half to "diagnose" the engine to determine if had any internal damage and would need to be replaced. They determined that the engine passed inspection and changed oil from 0W-20 to a heavier 0W-40 synthetic oil. Along with the oil change they added 10 ounces of MOA 115 stating that hence, will be required for every oil change. I got to reading up on this product and seems that it is safe to use in older engines. I use Valvoline VR1 Racing Oil for oil changes in my low milage T-Type & was wondering if there are any added benefits to supplementing these oil changes with MOA. Anyone using MOA in their TR's ???

Valvoline dose not want you to add any thing to there already well blended oil .
And I don't know what happened to your truck, But mechanic in a can and 0-40 is not a fix. GM spent years perfecting the oil system to work with 0-20 that has way less drag and no were will you find MOA 115 in a owners manual or in GM service manual.
So that's 1 no from me any one want to second that? on both T-Type and truck

Hi Dan, Attached is a video from Dave's Auto Center in Centerville, UT. Published about a month ago. They got their hands on a never installed L87 engine that failed GM internal testing. Teardown and analysis yielded concerns that GM has not yet addressed this issue from a few model years ago - 2022 or maybe even 2021 models with L87?

I don't like the band-aid solution GM provided you. GM's got a problem with these L87 engines that seems like the cranks were never polished when viewing the Ra and Rz surface analysis data. Check out the giant sized chamfers on the oil holes. A lot different than what the Manley aftermarket crank shows.

From the vid's you can glean a good idea of what's happening in order to make future decisions as GM provides you with band-aids hoping to get through the warranty period before the engine fails.

and another teardown video of a recalled L87 that failed somewhere between 60K -90K miles per carfax report.
