so the car is getting ready to roll over on 4k since the last oil change. i usually change it every 2,500 miles. but this time around i have no show of bad oil. what i mean is everytime i check my oil, its at the prefect level, and still looks golden, and doesnt smell burnt. but im wondering if that matters or not. the oil also has some sea foam in it. which has giving me great mpg (36 on the freeway, and about 29 city). and every other full up i put in some Lucas fuel treatment. so should i change it.. or wait a little bit longer till is starts to show that brownish black color?
