I am going with a longer interval, but plan on doing a used oil analysis to see how the Signature series performs over 9,000 miles or so that I drive annually.
This is compounded by the fact that 90% of people who do the short oil change intervals trade the car in after 4 years. Overkill, extra expense, and even if there were some marginal reduction in internal engine wear, you won't benefit at all from it.
There is one exception (IMHO) if you plan on keeping the car a long time, do one early oil change after 1,000 miles. Then jump on the manufacturer interval.
I plan on keeping my car a long time, at least that's my intention. I did my first oil change at around 4000 miles and my second just recently with the same 4000 mile OCI (car has close to 8000 miles). The oil looked really dark and dirty when I changed it out. I guess I will space out my OCI more now; since, it's a bit excessive, thanks.
