I am buying a 2003 Accord LX Coupe with M/T this weekend. I was wondering what some of you "oil gurus" would recommend for my regimen. I am pretty sure that 5W-20 will be recommended but I plan on using either 5W-30 or 10W-30. I have both Chevron Supreme dino and Schaeffers Supreme 7000 10W-30 on the shelf. I have been using SuperTech filters and MAY continue to use them pending results of my first couple of oil analysis....thinking that if I am able to extend oil drain intervals I may want to change filters. My thinking (which is dangerous and very limited in knowledge) is to change to Schaeffers at 3K, change again at 8k, change again at 13k and run an analysis each oil change until I determine the optimum extended drain for my engine. I would appreciate any comments or suggestions on this regimen. I really want to treat this car as if I plan to keep it forever. Thanks.
