Ol' Lord won't you buy me a Mercedes Benz. :-)
Loving the sprinter bro!
It's like 10 bolts and 45 minutes to do the transmission filter. You'll need to order the dipstick and filter from Amazon for under 20 bucks. Use Royal Purple tranny fluid about 5 quarts.
Oil changes are like $80 bucks at Walmart using Mobile 1 full syn European 0w50 or something like that. They carry it on the shelf. You need to bring your own oil filter. Scheduled oil changes are every 10k miles. I do mine every 3k miles cuz that's how I roll. Lol.
The Sprinter is the best van I've ever owned.
Parts are expensive from the dealer but you can find everything cheap on Amazon.
Currently, I have 306k miles on my sprinter 2500. No oil leaks, not burning oil and I can practically pull a wheelie off the line.
A+ would recommend
