How does the computer measure it? If it's done by miles then does anyone know what it is set at? Cuz I've changed the oil a few times and i Know it's not even close to 3000. Sub Q: I'm still running regular oil in it because i have done no performance mods, but was wanting some input on the advantages of a synthetic or semisynth. Thanks guys Also i just purchased rims on the web and will post some pics some time next week.
