But shoottokill had a point, he changed the oil every 4k miles. So in a smooth running hemi, I tend to agree with his analogy.

In my defense, Syn didn't warn before last time, so I'm pretty sure it is Syn's fault.

Just so others might know...
My combo of 6Qts SRT 0W-40 & 1Qt PUP 5W-30 & 4oz of ZDDPlus on my road trip today to my job interview (169 Miles) Total:---> took my mpg from 18.8 to almost 20.0 mpg. This pick was taken going up a large hill. Cruise was set @ 75 mph for 3/4 of the way.

So far 519 miles on this OCI!

Beware of My Voooooo Dooooo! It is some awesome $hit!!!

That looks almost identical to mine and I'm running straight 5/20 Castrol Edge Extended Performance. I'm getting high 18's to low 19's just back and forth to work. Haven't had it on a long trip yet but just 50 mile run to farmers market went to 22. I've never done an oil sample before but I've already got the sample bottle lined up for my next oil change. Really interested to see where it stacks up.

I prefer the Very Robust Sunshine Yellow though!
Gives / Creates that Warm Fuzzy Feeling inside that (Most) crave!
