Just a note. since you dirivng the vehicle under what would be considered "extreme duty". Similar to a taxi or police car. I'd take the service intervals that are in the manual and cut the mileage and time by 3/4. SO if it says to change a certain fluid at 30,000 miles. You should consider changing it at 7500-10000 miles.

The bad new is that even a '92 Accord is probably costing you over $0.50 per mile for the type of driving you do once you factor in all you expenses. So a 10 mile round trip for a delivery costs you around $5 in transportation expenses. Delivery drivers are generally underpaid and the hidden costs can be a killer. I generally tip fairly well knowing this. I should at least pass on what I saved by getting take-out.
