People brought math to a placebo thread.

Top of piston if anyone is curious.

Simple process of elimination if folks aren't doing in depth diagnostics.

I can try it, since $0 but new plugs went in.

Pretty on the money at 1.02mm, but that's ignoring some of the strap wear. It's tough to estimate the max thickness, but the min was in spec. The deposits are the main problem with the plugs having quality spark.

Plugs were installed 11/16/2024. Engine is an LQ4 aka 6L Vortec Vehicle averages about 1800 miles per month. Plug photo was taken at 155k miles, 31k on the plugs Engine OCI is on average 3,854 miles EGR was present for the majority of the plugs lifetime The vehicle is mostly used for heavy...

Rich usually shows up as lots of unburnt hydrocarbons, in otherwords "black." Soot can also indicate the plug is too cold. I'm asking what specific attribute of this plug screams "rich" or "forced induction"

Anyone want to try and do some reading? Figured some folks here would enjoy. This plug is indicative of the other cylinders. 30k miles NGK iridium, (non laser version) I'll save some of the other details since they might spoil the folks trying to read this plug. Edit: explain your answers

It's a bad plan for gaming, great plan for distributed server workloads.

The two options you are looking at are both DexosR. Be sure to disable AFM/DOD until you can mechanically delete.

That's what I do, I believe I posted the UOAs here. The manual days to use Mobil 1 15w50 in track, so I don't see why a 50 would be a problem.

Neither is "better." It's all tradeoffs.

I've returned Brand A filter citing the new order for Brand B filter. You just have to return the Brand A item. You can move to different products, but you have to return the already fulfilled order item.

I run my HVAC using one of these. https://a.co/d/03mQ80Ub Also if the appliance (hvac, water heater, etc) are 220, they'll run really poorly on 110. You'd need the appropriate 220 circuit on the transfer switch.

Engine came out of a CL1, so unlikely means anything to the Americans here. :ROFLMAO:

About 4k miles total. Hours would be tough to estimate, but the first pour was on 12/29/2024 if my spreadsheet is right. Most recent change was 11/2/2025.
