[img]/ubbthreads/images/graemlins/shrug.gif[/img] i have noticed a smell from the rotella i guess thats from the crankcase. smells strong when you are at idle and have windows down.. is this normal? also called dealer about changing oil before i go florida (i have 1700 miles on truck now)because of breakin oil he says ford runs there motors before they go to dealerships and drain breakin oil and put motorcraft oil back in what do yall think................ thanks

Rotella 15/40 year round. Synthetic is over rated. All the big trucks run Rotella with a million plus on them. I get a case (6 Gals.) for $36 at Sams club. Cant help you out on the odor, but thats my oil opinion.

My understanding on the break-in oil is that they leave it in. It is supposed to have a dye in it that will show up under ultraviolet light, in case any leaks arise during the first couple thousand miles. If I remember right, the oil is green in color. Good luck with your 6.0 and welcome to TDS!!!!!! [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

Any CI-4 /4+ rated oil. I use Delo 400 & have had no problems. Rotella is good & meets spec. No problems.

Most guys will use synthetic in the cold areas.

I used Shell Rotella in my Dodge Cummins for 13 years. Always had an odor after an oil change. It went away after a week or so. Will be using Rotella in my new Ford also. I have that permanent smile now that everyone talks about when I'm behind the wheel! [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]

Rotella here also. I paid to have the stealership change it at 2500 to get rid of the break in oil. The 5000 mile oil change was free. Both times the stealer changed it, I had a slight case of the romps. I have put Rotella in it ever since and no romps...

I changed my oil at 1700 mi, just to get the green dyed Motorcraft 10W-30 sludge out and it was noticebly green. I use Rottella T 10W-30 in the winter and 15W-40 in the summer and did in my 7.3s as well. I can not say that I have ever noticed any unusual smell from it though.

It is my understanding that Ford puts 10W-30 oil in them at the factory with some oil dye for the inevitable oil leaks. [img]/ubbthreads/images/graemlins/phoney.gif[/img]

The Shell oil is fine, I generally use Delo 400 myself. The smell you get from the crankcase, is it engine oil smell or the smell of raw diesel?

My truck stinks of raw diesel from the crankcase, even though the level does not rise noticeably. Ford says "this is normal". Well I think they are full of it as I've NEVER smelled raw diesel from the crankcase of any diesel engine unless it had a problem!

Schaffers 5W40 Supreme 9000 and a Mobil 1 oil filter...good for 10000 miles and 1 mpg...

You're probably going to laugh at this one! I have a fleet of ford ambulances, and i use valvoline 15w40. I change oil and filter every 3000 miles, and a 55 gallon drum lasts me about 3 weeks. I have 2 '98 7.3's with over 300k, 3 '01's with over 200k, and 5 or six others with over 100k. I have NEVER had any internal engine problem with any of my trucks. I am a firm believer in changing oil more regularly than spending a fortune on oil and going 10k miles.
