My 2 part question is : Can I just up and switch to synthetic, like would there be any steps I'd need to take since I've had 4 prior regular oil changes, i.e a flush?? Oh and when would i have to change synthetic then, and can Nissan do the synthetic oil change for me ?
im a noob.
Yes you can switch directly to synthetic. There's always going to be a little bit of conventional oil left, probably for the next few changes depending on how well they drain, but its not going to be a problem.
Yes you can have Nissan use synthetic oil and do the change for you; it will just be more expensive. That's why I do oil changes myself - you can stock up on full synthetic when its on sale and do the change for the same price you paid for a conventional change at the dealership or wherever. Plus you have peace of mind that everything was actually done right.
