If it doesn't say CJ on the label ( CJ compression fired) then it's a SI (spark) gasoline engine oil. Putting a SI oil is a no no, you can use diesel oils in gas engines, a lot of guys that race use it, but not vice versa. Forget what Joe blow and the internet says, go by what the mfg. specifies.

Just an update. I now have exceeded 100K on all three trucks used in my HVAC business. Not much has changed. I do not have any problems with my trucks with continued 10k oil changes. Other than getting more oil out than I put in, which has not caused any problems for me. In fact the only problem I have had was with my 2009 leaking radiator hoses, which my local Ford Dealer replaced. The other two 2008s are still chugging along with no issues. I believe the synethic oils have helped prevented any major engine breakdowns. I choose to follow the manufacturer's normal maintenance schedule of 10K oil changes stated in trucks' manuals.I respect everyone's opinion and input on this topic. If I have a problem I will post and let you know the outcome.P.S. My 2009 is mostly highway miles, the 2008s are combination of city/hwy. Motor oils are Mobile 1 15-50w or Royal Purple 15-40W.

If I recall correctly that is what the EPA had sated in their report? If you can't get 200k-300k out of this motor with good maintenance then something is wrong.

Well international claims the B50 life of the engine is 375,000 which is odd because i though they orginally stated it was 330-350,000 when it first came out, looking at that info im not sure what emissions are tied to the meduim duty truck class that may differ from ours, but u can see the output is offset alot less so.

Navistar's current 6.4 (maxxforce 7) is rated at a B50 of 500,000 and for anybody who is not familiar with what the b50 represents, it's 50% of the engines will require a major overhaul at those quoted miles.

There is a difference in engine construction materials between our 6.4 and Navistar's 6.4 one of them is the block is a graphite impregnated cast iron composition similar to Fords 6.7 engine.

I wonder if the new maxxforce 7 motor will bolt right into our trucks? If my motor ever goes i would like to try the new design out.

I know this is de-railing the thread a little
but it was my understanding that it was not until 2010 that navistar went to the CGI block which would be the diffrence between the older spec sheet i had and the new one on there web site with respect to the changes of the b50 rating. Also the big improvement in the b50 rating, from what i read was that the new 6.4 navistar went away from in cylinder dosing or somthing like that which greatly reduced the diesel in fuel problem. Which raises the question does the 2010 6.4 in the fords share this change with respect to the block material being CGI?
