Here's my situation: 98 SL2 (62K miles) living in central NY. I only drive it a few times a month, usually for about 5 miles each way (half of them on highway, half on surface streets). So, maybe up to 100 miles/mo.
Before, in San Diego (when I drove 1K/month), I was changing with Mobil 1 synthetic every 3 months. Minimal oil consumption. Any opinions on whether I can safely decrease my oil changing frequency given my new circumstances?
