I'm a new member, and I think my wife suspects I'm surfing porn sites with all the time I'm spending on BITOG! You folks are an incredible resource. I have an Acura TSX 4 cylinder 6 spd just turning 102,000 and have decided to do my own OC's. 5W-30 recommended (and always thought W stood for weight *G*) and the car averages less than 6K yearly and no oil leaks. Is a high mileage oil recommended, and should I use a synthetic or conventional? Planning on using the OEM Honda filter. Thank you in advance!
