Oil weight influenced by epa mileage targets?

Interesting article. I think we’ve all suspected this since the 22+ tundras started blowing engines.

Are OEM Oil Recommendations Influenced By EPA Rules? Here's What One Expert Has To Say — SlashGear

Using lighter weight oil in an engine reduces friction and gives better fuel economy, but it can lead to engines wearing out earlier than expected.

Absolutely, has been the trend for more than a decade. Why allow for long term durability when you have targets to meet?

Sad, but true. Not Toyota specific but industry wide.

I was in a reddit about oil weights, mentioned weight vs longevity... it's all politics but places like Dubai use 5w20/30 for longevity rather than 0w20 for mileage ratings.

EDIT : Just to concur ^ post

Because Dubai doesn’t get freezing temperatures. 0W-20 and 5W-20 oil has identical performance when engine is at operating temperature.

Summary of the article. “Don’t listen to what you read on the internet, but follow OEM recommendations, except this recommendation that we will make”.

Lol, so true.

I gave up on 0w-20as soon as what we all suspected came to pass. The GM debacle was the clincher. iF IT SAYS ANYTHING w-20 REALLY MEANS RUN 0w-30. i AM FINE WITH THE COLD WEATHER ASPECT OF ALL THESE OILS, BUT WHEN THEY ARE WORKING, they need more. The Toyota LC250 will always see 0W-30. .1 mpg does not impress.

Like most of you, I have settled for one of the Xw-30 flavors until we have long-term, real-world ownership experience on the Xw-20 varieties. As pointed out, that about-face by GM was as close as you'll get to an OE admitting to the performance capabilities (or lack thereof) of a thinner oil.

I wonder how many turbo failures running 0W-30 will cause. I guess we will see in a decade.

To this end, have there been any oil-related issues with the LC powerplant? Time will tell I suppose, but good grief, many of the new Toyota engines, such as in the Crown, call for 0W-8.
