I have a 1993 Toyota MR2 Turbo with 83,000 miles on it. It spends most of the time in the garage and only gets driven about 1000-1500 miles per year. Some of the driving is on autocross courses a few weekends a year.
I've been changing the oil and filter once a year (Penzoil Platinum full syntheic 10W30, OE Toyota filter).
Should I continue with my current OCI or can the oil perform well at longer intervals?
