Ramrod79 Posted June 25, 2023 Share Posted June 25, 2023 I just rolled over 20K km’s on my 2019 6.7 F350 and only had 1600km’s from the time of my last oil change but it has been 11 months so I figured it was time to replace it. Quote Link to comment Share on other sites More sharing options...
CharlieKelley Posted June 26, 2023 Share Posted June 26, 2023 I go by miles only, not by time. I think oil can last more than one year. If it's a barn find or something, sure. But one year should be fine. Quote Link to comment Share on other sites More sharing options...

Ramrod79 Posted June 26, 2023 Author Share Posted June 26, 2023 If I went by distance I would probably only be on my second oil change in almost four years of owning my truck, although it does feel like a waist of money I swap it out anyway. It was pretty hard not to sell it while used truck prices soared but I couldn’t justify the replacement costs. Quote Link to comment Share on other sites More sharing options...
boarslayer Posted June 26, 2023 Share Posted June 26, 2023 I once waited almost 2 years to do an oil change on my Camaro, because I was going by the mileage. I ended up with an oil leak around the filter cause the seal went bad. I do it once a year now no matter how many miles I drive. Quote Link to comment Share on other sites More sharing options...
