Got an oil change and put mobil one sythetic in it. its been about two weeks, it seems pretty dark. i know its a dark oil to begin with but it seems really dark. is this common on this truck. its a 2008 Ram V8 4.7L. its my first oil change on this truck since i bought it a few months ago. just wanted to see what you guys thought. I'll post some pictures tomorrow morning or afternoon of the dipstick.

 

I recently switched to Mobil 1 myself and it got darker than usual sooner than expected but I remember people mentioning it's just the better (full syn) oil doing it's clean up job from the previous doo'doo that was in there. I'm sure others will chime in as well.

Welcome to the M1 club

 

Its fine. M1 is a good oil its the only thing I currently use and its the only thing I used in my old F250 and in my moms old Dakota, never had any kind of issues from it.

 

Yeah, it'll tend to get darker quicker because of the additives(cleaners). Right before you do your next oil change, pour 1/2qt of Marvel Mystery oil and run it for a day or 2 before you dump the oil out. That will clean it up nice and polish the internals. Again, at the end of this oil life. No need to dump it out right now.

 

yeah you still have crud from the previous oil. mobil1 is bomb

 

Looks like I found myself something to do before my next oil change. How many miles with that stuff would you recommend because I don't rack up hardly any miles daily unless it's Wed. or Thur.

 

You mentioned Marvel Mystery oil, i was wondering what it is all about. Is it compareable to the Lucas product line?

 

If it's gotten very dark that quick and it's a 4.7, keep an eye on temps.
If it's removing a lot of sludge from a previous owne,r who wasn't careful about service intervals, it might cause some damage.
Not to say this is happening in your case, but just be aware of synthetics excllent "cleaning" abilities.

Here's what it looks like, I the size is to big sorry mods. I uploaded them to photobucket with iPhone and don't see a way to down size them.

 

I ruined a engine once using Marvel Mystery Oil. I poured it in on a perfectly working engine and not too long afterwards it started to knock. When I pulled the engine and took it apart, the MMO did what it was supposed to do and broke loose everything in the engine which then plugged my oil filter and oil feed/drain veins and return holes in the valley and ran the bottom of the engine dry. So I ended up spinning two rod bearings and destroyed a crank
