I have a 2001 honda civic 5 speed with 163,000 miles. Guy i bought it from said he did 5,000 mile oil change intervals with reg.quacker state conventional 5w20. Car runs great and uses or leaks no oil. What oil would you guys use on this car. Its driven mostly city 10 miles each way to work with the weekend freeway trips. I have no experience with quaker state and really value your opinion. Thank you everyone.
