The debris that is cleaned can get past piston rings into the oil sump so you should change oil soon after that tank of gas is gone. Replacing the sparkplugs should improve efficiency also. Search this forum to decide which oil to use.

The check engine light is ok and I changed the oil almost 2 weeks ago. I used Mobil 1 0w-40. I also have lucas oil injector cleaner I can use, I don't know why I didn't think to put some in the tank. I haven't been using chevron gas though it's expensive. Since I got the car I've been using arco 91 premium.
