The ‘20 Corolla 1.8L non-turbo owners manual states to use 0W 20 oil with no other oil weight options listed . Are there any special engine requirements (VVT , etc.) for the ‘20 Corolla 1.8L that would prevent a 5W30 synthetic oil being used ?

Hope you don't get a warranty related engine problem.I have a '22 Corolla with the same engine and have used 5w30 since it's first oil change.
Perhaps he’ll post the portion of his owner’s manual or warranty booklet that states the oil grade is connected to his new car warranty.Hope you don't get a warranty related engine problem.

can/would the manufacteuer even check the weight? I asked Honda dealer service manager and they said no. Is this all an internet old wives tale? Just saying...Hope you don't get a warranty related engine problem.
If there was an internal engine related problem, they will ask for oil change records at the minimum. If it shows you didn't use the recommended oil and they want to be hard nosed about it, I can see them denying warranty coverage.can/would the manufacteuer even check the weight?

Specifically for "fuel economy and good starting in cold weather." No mention of protection. Besides, I'm more worried about my Hyundai blowing up than I am one of Toyota's most reliable engines.The manual states 0w20 is the "best choice" not the ONLY choice. Big difference.
Except that nowhere is it related to warranty. The endless fear mongering about this is getting beyond ridiculous.
The attachment states that 0W-20 is the best choice for good fuel economy and good starting in cold weather. If cold weather is not an issue, and fuel economy is not a priority, then might not other grades be acceptable. 0W-30 and 0W-40 would also provide good starting in cold weather.The manual states 0w20 is the "best choice" not the ONLY choice. Big difference.
Arguably a 0w30 would also meet the definition. It just depends on what you're comparing it to.

I would disagree on the sole basis that he could be using some bargin dollar store BS 5w30 which will in fact harm the engine over time. A 0w20 on that basis alone is a better quality oil.Except that nowhere is it related to warranty. The endless fear mongering about this is getting beyond ridiculous.
On the other hand it is a perfect example of what the CAFE required wording is supposed to accomplish.
There's the third way that 0w20 is fine as well although fuel economy is the inherent advantage to using it.I would disagree on the sole basis that he could be using some bargin dollar store BS 5w30 which will in fact harm the engine over time. A 0w20 on that basis alone is a better quality oil.
Let's be real though the fear mongering goes both ways.
"xW20 will ruin your engine slowly, it's too thin, it's only for CAFE."
"Using a non-approved oil will ruin your engine and cause warranty issues, it was designed this way, don't mess with OEM requirements."
At the end of the day, it's probably a wash which nothing but conjecture either way. Just like everyone's opinion on interior or exterior looks.
