Well I just did a basic tune-up to my 1998 Honda Accord yesterday and it seems to drive much more smoothly now. I changed the distributor cap, ignition rotor, spark plugs, spark plug wires, oil, transmission fluid and antifreeze. I had NGK iridium spark plugs before and now I switched to the NGK G-power platinum plugs.
I also switched over to the Mobil 1 5W-30 fully synthetic oil. I switched over to the fully synthetic oil since it is suppose to help with gas mileage and engine life. I will make an update when I find out since I always keep track of my mileage when I fill up. I do notice the shifting is much more efficiently even though it is an automatic 🙁 . Oh, here’s something I found out when changing my oil to full synthetic. My car calls for type SJ oil, yet the Mobil 1 oil was type SM. While I knew it was safe to use, I just wanted to find out what is the difference between SJ and SM oil. My results: in a nutshell, the oil types are basically going thru the alphabet and since my car calls for SJ and the Mobil 1 was SM it was an upgrade. The SM is a higher grade oil, and you can always upgrade, just not downgrade. Hope this helps anyone whoever wondered this.
