Have to take a 600 mile road trip on Friday - Not going to have time to change my GC. Car is a 99 Infiniti with the SR20DE motor. Have a Wix filter and 3.8Quarts of Green GC. Last changed about 8 months ago. 60%city 40% highway. Consumes little to no oil. Right now at about 6600 miles into the interval. Can I push it to 7000+?
