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?
If you are doing the change yourself, what's a few bucks (Mobil 1 Synthetic is about $25 for 6 qt. and Ford filters less than $5) twice a year on a very expensive MH? The kind of driving you do, dusty roads or long Interstate or very short local trips really determine when you should do an oil&filter change.
