You're probably right but I went ahead and disobeyed running 10w30 right now. Im anxious to see what 5w20 does to the readings. But I only have 900 miles on this oil! Not sure if I can wait.
When you change to xW20 in the future, please post the oil temperature you're observed. My guess is that 1 weight thinner oil will lower the temperature in the sump by up to 10F with similar driving patterns and ambient temperature.
