Honda CRV calls for 5X20 oil---should I continue using same oil over 100,000? Another Honda uses 10X30--what viscosity should I use when mileage is over 100,000 for an accord? Should I change to synthetic for both and use what viscosity for each?
well after 100,000 miles its best to use 10w30 oil for high mileage cars.my integra is supposed to use 5w30 but it has 130,000 miles and the 5w30 doesnt last.i use 10w30 and it works better!since of the high miles
