4000 Mile Checkup - 950T
I'm coming up on 4000 miles and will be doing my own oil change this time. I did the 600 mile checkup and change at the dealer because they had a good deal going on at the time. I have a few questions about this process
1. They put semi synthetic oil in last time per their recommendations. Will it be too early to go full synthetic on this change, or should i wait until the 8000 mile?
2. Any other items I should be checking out for besides the obvious, (tires, loose bolts et)
Thanks in advance for your input.
