I agree. I think 0w20 in combination with low tension rings isn't a great idea.
An appealing reason t try the 5w30 synthetic is that there is plenty of selection and its WAY cheaper to buy. Probably gonna go with Kendall, and if it seems to alleviate the oil useage, switch to Amsoil. I just CAN'T see pouring in $10 quart oil if its burning it up.
