A short time ago I started a thread here Titled "High Mileage-Really"
I was looking long & hard to find a long bed pickup truck in halfway decent shape to pick up lumber, etc. locally for some DIY projects here at home. Quite by accident my wife spotted one on a used car lot in a town we were passing through. To make a long story short, it turned out to be a 2005 Dodge Ram 1500 SLT. The dealer allowed me to take it all the way to my mechanic for an inspection. Everything appears to be in reasonable condition for a ten year old truck. It appears to be running well so far.
On the day I went to pick it up from the dealer, all the fix up work that I asked for as part of the deal was done. But they did not get to do the oil change. So the dealer gave me a card so I could take it about a mile down the road & have the oil & filter changed at no cost to me. Got to the quick change place & they drove it into the service bay & did the change. I asked the manager what weight oil they installed & I was told it was 10W40.
Here's my question. I intend to change the oil again as soon as I put on 500 miles or so. I want to use a High Mileage oil. The owners manual states that the oil specified for the 4.7 ltr. engine is 5W30. The one drawback to this truck is the high mileage which is at 213K . My thinking is that at this point with 213k the better oil to use would be 10W40, because lets face it, I don't know the maintenance record of the vehicle over the long haul. It could well be that the previous long term owner used 5W30. Or they could have used another weight.
I'm tempted to use the 10W40, but the owners manual has strong words on varying the oil weight. Personally I think the language in the owners manual is nothing more than legal mumbo jumbo against repair claims, which in my case cannot be made. Dodge Ram is not my first choice. I hunted for a ford F150 long bed & just got tired of the hunt. Opportunity came with the Dodge & I took it. So what's your opinion on the oil. I'm not sure other than I want to use one of the High Mileage formulas.
Tried to post some pictures, but I haven't figured out how. Sorry
