Use 10W-20 as a replacement for XW-20 and XW-30 applications?

For general guidance, I would say above freezing. Below that I think it is important to realize the lighter oils will shine. This particular oil was designed for warm climate use seeing triple digit heat. Low volatility was the goal. It is really good in that department.

How about a cold weather version in 0W-20? Zero or as low as possible VI. Like a Ravenol ECS.

In winter id run the RL 5w20 for it's stability but the 10w20 has my attention for a summer or fall oil most certainly. I think the esters will keep everything clean and DI deposits in order.

SAE J300 says if an oil is rated as a "10W" that it has to pass the CCS test at -25C (-13F).

Picked up a case on Monday. Now I need to find something to use it in…

Edit: FCA allows the usage of 10W-xx at temps above 0F but prefers the use of 5W-xx at temps below 32F.

So, the conservative recommendation is to probably restrict usage of this 10W-20 product to applications that do not see ambient temps below 32F.

Gives one a pretty good idea of how low the bar is for the API approval eh? In terms of shear resistance and stay-in-grade requirements.
