Ethanol blended gas (good or bad?)

Guessing I should have read your post more closely. I need to use the good stuff cause my engine was pinging I have 10 1/2:1 Slugs and was clicking a little. The 318 which I also ran for ever never had that problem so Im Thinking you should be ok with esso,shell or so. If your car goes thru gas like my does and you don't need the expensive stuff cool D
