Hey everyone I'm new to the forum but have had my truck for about 3 years now. I tried searching but don't know what to put in for search so it'll probably get moved to somewhere else. So I have an issue, I changed my oil at 145,600 miles. I now have like 146,xxx not even 1000 miles since last change. I reset the dash to say 100% but now the percentage is at like 20 something %. I do it myself too. Any help or thought would be appreciated thanks.
