I have a ‘96 gsr that has recently been tuned to get rid of a spark ping issue. Went on a road trip (~400 miles), got into vtec one time, and once I got back into town the oil light started flashing steadily. Drove it home, parked it, and the dipstick had no oil on it when I checked. No smoke, smell, or leak that I can see without putting it on a lift. Car runs and drives fine with no weird engine noises. Any ideas?
