I'm one of those vehicle owners that put only about 4500 miles annually because I use public transportation in the NYC area. I've had my 2000 EX since August, but it has less than 2000 miles on it. Should I wait to hit the 3,750 mark to change the original engine oil formulation? It's got mix of 50/50 highway and suburban local miles. I think I should change in the spring, which would be about 8 months & 2,200 miles. Any opinions? It may be at the anniversary before I hit the 3750 mark.
