Good evening gentlemen.I am new here so if I do or say somethin out of place,please forgive me.Ya see,I'm not very bright!! lol lol Anyways,regarding the oil change,I bought my wife a brandy new 2015 Patriot Altitude 4X4,with a 2.4 motor,with an automatic 6 speed, last April and just did my very first oil/filter change on it this AM as it only has alittle over 4000 miles showing on the clock.I used a Wix filter and 5/30 Dino oil,which is what I use in my 2014 Tacoma truck and the wife's previous 1999 Cherokee and 2010 Liberty,[both bought brandy new] the Liberty being the vehicle we traded in on the new Patriot.Infact,I use Dino oil in everything I own.So unless you do a lot of city or shot hop driving,4-5000 mile intervals should be about right.Hence if ya do a lot of miles over a short period of time, you can extend that interval even more.But if you do short mileage,like all city driving,then ya might wanna change it at 2500-3000 mile intervals.Oh I forgot to mention that I am a retired automotive equipment mechanic,retiring from my last place of employment after 35 years.But I still dable in the business which I've been in now for a total of 61 years.[I'm just a kid!! lol lol ] So like I said,I'm not very bright!! lol lol Hope that atleast gives ya a direction to go in regarding oil change intervals!! Dave!!!
