3k miles, 5k miles, 10k miles, 15k miles… We can argue about the merits and drawbacks of all of the potential intervals, but lets forget all that for the purpose of this particular discussion.
Here is the question for you, how long have your vehicle gone on a single oil change? What oil did you use and what vehicle was it?
My personal highest is 10,250 miles on my 2013 Prius V. I was going to change it sooner then the 10k interval but then my wife hit a skunk and the car is tainted and its a lease so its going back and I don’t care. Plus the engine was not running all of those 10k miles since its a hybrid. The oil looked fairly clean even though it had 1 year and 10k miles on it.
Ok, my mother has a 2002 Dodge caravan, 2.4L 4 cyl. I changed the oil in june 2009 at 23,323 Miles using mobil 1. I changed it this week at 54,700 miles. My father says he changed it once but after looking at the oil filter its doubtful, I really think the van went over 30k miles and 5 years on a single oil change, the van was a half quart low and the oil looked fairly dirty but I have seen dirtier from an old vw beetle I had as well as a jeep wrangler I had that never seen more than 4k mile intervals its whole life. That jeep dirtied the oil quickly for some reason.
I can not confirm for sure that the van had 30k miles on its oil change however I am fairly certain. I know how lax my father is on vehicle maintenance and thats why I used mobil 1 ( not saying mobil one has some super interval or its ok to stretch the intervals using it, I just figured it would not hurt.). I told my father 3 years ago that the van had a timing belt and it should be changed and said " I know I know, we will have to get it done." A year later it broke leaving mom stranded on the interstate. When the shop did the belt I suggested that he have them change the oil, my dad said he was going to do it, and I don’t think he ever did.
I was going to send out the oil for a sample but I got lazy and I was short on time and i also had to replace the radiator in the van so I had to work quickly that night and i kinda blew the oil sample off. I kinda regret not getting a sample now, oh well.
I am not saying going 30k miles and 5 years is ok, I am going to start keeping on it since my father is getting older and obviously has no interest in maintaining the van.
Whats your record?
