The bearings in the GM 5.3L L84 engine commonly use copper-based alloys for strength, wear resistance, and durability. Specifically, the main and rod bearings typically feature:
•    Copper-Lead Alloy: A traditional bearing material combining copper with lead, offering excellent load-carrying capacity and fatigue resistance.
•    Copper-Tin Alloy: An alloy that enhances strength and wear properties, often used in engine bearings to handle the stresses of internal combustion.
•    Layers or Coatings: These bearings often have layered constructions, with a steel backing for support, a copper or copper alloy intermediate layer for strength, and a soft overlay (like babbitt or a tin alloy) on the surface to provide conformability and embed debris.
In modern GM engines like the L84, the use of copper-based alloy bearings reflects a balance of durability, friction reduction, and compatibility with the engine’s lubrication system, which includes specific synthetic oils recommended for the engine. These alloys help withstand the high loads and temperatures inside the engine while providing good resistance to fatigue and seizure.
Overall, copper is a crucial base metal in these bearing alloys, enabling long-lasting engine performance in the L84 5.3L V8.

Lead has been dropped for EPA requirements

Well, copper shows up 100 times in that report. LOL

Two things I noticed. My oil change indicator said 50 percent but the sticker from valvoline said I had 3K miles to go. I pulled out the receipt sure enough it was 5K miles since my last oil change. Interesting. Their business is changing oil. I guess the 5-20 is more expensive than 0-20 so they up the interval? Anyway there’s no difference in fuel mileage. If anything it’s a little higher.

Wife’s 2011 Genesis sedan 148K oil change at 4K miles. Grease Monkey 5-20 Mobile one. Had a coupon. Stood at the bay and watched. I don’t care I watch. Stop them from adding water in the washer. I add washer anti freeze this time of the year. Went to auto zone for cabin and air filter. Changed there just in case. Mark their sticker in the window from 3K to 5K oil change. This car doesn’t have a minder. Still drives as new presents better than its years. Totally unexpected.

My wife drives under 10K miles a year. Her car before that was a 2005 Elantra GT my grandson drives now. We started buying Hyundai because of the warranty. This one surprised me.
