I usually get one every 5K miles or so… but have went up to 10K+ (and even seen some over that with no problems what so ever). I read an article (possibly posted on here) that car manufacturers are actually upping the required interval to 8K-12K miles on newer vehicles that come with full synthetic oil from the factory… possibly due to oil costs and increased technology.
Aren’t dry sump oil systems designed to go even further?
obviously you should do it more frequent if you beat the shit out of your car /disclaimer
I go about 3.5-4k miles on full synthetic. I know that i could probably go a lot farther, but with the warranty i need to have receipts showing i get it done within the ‘recommended intervals’. It’s already paid for a new engine, dont wanna f up the possibility of another
3K on all the DDs. once a year on the fun cars; which is less than 1000 miles. I use mobil 1 on my srt and daytona, royal purple on my charger, and dino on my wife’s VUe.
The reason the manufacturers are raising the mileage between changes is to lower the maintenance costs of the vehicle. Dodge and Toyota both got burned on this because some of their engines were sludging up if you went more than 3K between changes. Also they require lower mileage between changes for their sever duty maintenance schedule. According to most owner’s manuals ever thing you do is severe duty.
