Since I don't change my own oil, I have always change it at 3750 mile intervals (once between 7500 m service intervals), mostly for convince sake. Every 3000m for me turns into two 3000 intervals, followed by a 1500 interval. If the a signant differencetween 3000 and 3750, it mght make sense for me to go to synthetic, at 3750 intervals. Or, again, 2500 dino intervals (every third change being a regularly scheduled service. I've thought of sending an oil sample to George Murphey for an analysis.
I am concerned about the greater heat with the 119 engine, even though I live in the Bay Area. With the A/C on, it will often go past 80 to 90-100+. I try to make sure it never goes over 100, and try to keep it at 85-90 by turning off the A/C.

I don't mind spending the extra $ for syn, if it means extra longevity for my engine - unless gasoline becames extinct, this may be my last car. I just wish there was some documentation.
