Is it recommended to use SAE 5W 30 oil and why? I've been using 10W 30. My valves have been ticking louder than usual but I have not found any oil leaks or can the gas grade affect engine performance?
Any response helpful, thanks. Kansas88

in the winter you should use the 5w-30 and summer 10W-30 is fine. This is when it starts up in the cold correct?

Just an FYI....

I was at Menards today (a large chain store in the Midwest) The have Quaker State Peak Performance for only .69 per quart. All Grades
