That's what I usually do for the warmer months. If it weren't for sales, I'd use it all the time. Am currenty using Rotella T6 5w-40 and a Purolator classic. Was going to use a Napa Gold oil filter but they gave me the wrong one.
I ran Mobil 1 0w-40 last winter, just sent in my sample and should get the results soon. Compared to T6 5w-40, it runs smoother and gets up to temp quicker when its below freezing. That's good for me since I only have a 5 mile commute to work.
Paid $38 for 5 quarts oil and the filter was $13. That comes out to $5/qt, which is slightly cheaper than Rotella ($22/gal).
