Ok, I finally got a second car to use as a daily driver and kept the R in the garage, protecting the garage floor from dust. So my daily ride now, and for the past 2 months is a 89 V6 5spd 4WD Toyota Truck (It's gonna get lifted and get bigger tires), which should last forever and not attract tickets as much as the R. I have three separate questions:

1. I use to do an oil change and tire rotation (car lowered 1.75in and there front and rear with Camber kits) every 2,500 miles at the dealer, but now since I drive the bucket (the truck) everywhere and rarely drive the R, my guess only will be driving it under 2,000 miles a year from now on, how often should I change the oil? Can I go longer than three months, say 4,5, or even 6 months?
2. My plan with the R is to drive it or at least start it and get it up to normal operating temperature once a week. Is this enough to keep the car from sitting too long?
3. Final question is before my last oil change the car was driven rarely (once a week) because I got the truck the V-tec wasn’t kicking in until 7,500 rpm or higher and the oil light started flashing. So I checked my oil and it was low so I added a quart of 10-30 Castrol (what I normally use and the dealer puts in 4 qts). My car is a 2000, has about 67K miles on it, and I do drive it hard for a daily driver. Can R’s burn oil being used as a daily driver that is driven hard(high revs typically in the 5-7K RPM)? The service person at Acura said they can burn a qt every 1K miles, is this possible? I thinking about adding half a quart every couple months and doing an oil change every 5-6 months, any thoughts on this?

Thanks in advance for you comments and info.
