Run it in the summer and year round if you don't get cold winters. Send in an oil sample after 5,000 miles to see how it holds up its really the only way to know.
Yes. The V6. This is our second VQ40DE. One of my favorite engines mainly because I know my way around it from owning our old Xterra with the same engine and it was solid (98k/ten years when sold and nothing but normal maintenance). I do plan on running it year round since I live in Georgia. My other concern, only because I had read it somewhere, was the harm, if any, to the catalytic converter. But if I read the bottle right, it did say CK/SN so I'm assuming it would be OK. I just changed the oil in the Frontier after my wife got back from Florida so after this 5K run with the last of the Kendall 5W30 Semi-Syn I'll be giving it a try. Appreciate the responses.
