We have a 2011 29' motorhome with a V10 engine. I took it in for an oil change at the dealer yesterday and was told I should change oil every 3,000 miles. What do you think/do?
I had a v10 Excursion and loved it... A rock solid engine.
I've always said the 3k miles was big ol "make money" lie. The engine, oil and filters today are made to withstand a lot more strenuous workloads. I generally say 5k is the standard, but you can go 7.5k miles. Always check the fluid levels every 1k miles or so, the greatest risk is low level and not oil break down.
All if that said.., if you feel better changing it at 3k, then do that.
