As for efficiency, that's simple. Heavy oils are thick oils, and thick oils require a lot of energy to move around. As fuel economy regulations tightened, automakers looked for more ways to improve efficiency and add another mile-per-gallon here and there. One way to do that is by using a low viscosity oil. The less energy an engine uses to lubricate itself, the less gas it uses in the process. There's also the fact that as engine technologies and materials sciences have improved, tolerances have gotten tighter and oil passages have gotten smaller. Lightweight oil flows more easily and can get into all the nooks and crannies inside an engine easier than, say, 10W-40.

I only posted part of the Link, we have heard about Tolerances being Tighter, we know that is not true. The nooks and crannies inside an Engine Comment. Wow

The oil passages have gotten Smaller! Really

Wait - are you saying that MSN got technical details wrong? Say it ain’t so!

MSN is my Homepage, let me stay Neutral. LOL

Do not get your Oil Info from MSN, get it from Members here on Bitog!

Lmao on all of that. What a bunch of nonsense.

I always wonder, what’s in those infamous “nooks and crannies” that is supposed to be reached only by thin oil?

I seriously doubt that was written by a human. More AI generated crapola.

This is the eye catcher.

Now think thousands of recalls. Think thousands of con rods busted through engine cases/ blocks. Think thousands of spun bearings.
Think thousands of ruined cams and lifters. Wet belts and all the other crazy issues.

Yeah that person that wrote that needs to do a better study, and realize nothing has been improved, if anything it has degraded.

The article had me up until jalopnik. No wonder it's nonsense.

Do you really believe that was a person who wrote that?

I hear the 2026 Toyota engines will be so tight that only oil fumes will lubricate certain parts

If not, some college educated brain proof read it before posting it.

And they sure make same engines with larger oil passages for markets outside North America to allow thicker oils...
