I usually stick to the book when it comes to oil, antifreeze, etc. but have noticed a huge price difference between prices of the 5w-20 and the 5w-30, especially since the 5w-30 is available in 5qt containers.
Basically, I just want some direction as to what some of you are using and if you would feel comfortable using the 5w-30 oil in place of the 5w-20. What do you feel are the pros and cons?
Thanks for your help.
