Sold off our 2013 CRV and snagged a 97 Civic 1.6 SOHC VTEC with 148K on the clock. Previous owner had all the maintenance done on time at the dealer so it's in spectacular mechanical shape. I know the 1.6 VTEC's are prone to consumption/burning as the miles increase so I'm lost as to what oil I should feed it. Jump to synthetic? High mileage? Stick with conventional for short intervals? I've never owned a vehicle much past 100K. Help a newbie out ;-)
