snowmover interesting question cause i recived a free oil change from my dealer when i bought my new truck 6.0 also i went in to get it done and the adviser said they were gonna put 10w30 in for oil i said dont think so he showed me a bull from ford saying ok to use i think its the ford dealer trying to save some money i passed on the 10w30 and had rotela t 15w40 put in just dont think a diesel should run 10w30.
Also i wouldnt use syth oil with a green engine you should wait til its broke in maybe around 15k before you consider syth just my two pennys
CI-4 is the new API specification for motor oils.The newer oil must meet some pretty stringent standards to deal with the newer motors now using EGR,and low sulphur fuels.It a nutshell,it means it's better than the old stuff.It is also fully backwards compatable.
Like Fred said above,hold off on synthetic until it gets some miles on it.
I have a 99 F350 powerstroke, and prefer to run 10W-30 Rotella in the colder months. My truck does not like the weight of the 15W-40 whens its cold out, I have had the cold start problem, even after check glow plugs, relays, and plugging it in. Once I changed to 10-30, no more cold start problems, I don't even have to plug it in. The hardest thing is finding someone around my neck of the woods that can get it, no body seems to have it or get it.
I must admit- I'm lazy. I do my own brake jobs, most engine repairs, I've even done an engine swap (350 in S-10) :burnout
However, I DESPISE changing oil. So I go to the dealer's quick-lube. They have 15w-40 in the diesel hoses during the summer, but have switched to 10w-30 for winter. Both are Rotella products. It was 12*F here this morning, and I forgot to plug in last night, :headwall but she started great this morning!
You must be lucky, I went to five different places around me to get it, they told me either they could not get it, our had to order at least 300 gallons in order to get it. I finally found a place that could order it for me, but it took me three days of calling around to get it.
jbutch i havent ever seen 10w30 rottella around here either i remember years ago like back in 85 i worked at a shell service station and i was pretty up to date on there products and that oil was like a special order product .
i here ya on the hard starting on the 7.3 our 97 its either plug it in or replace a starter i have spent a ton of time making sure everything is right its just a hard starter, what i ended up doing was installing a sneaky pete injector unit instead of using starting fluid i use wd40 and its starts right off.
one big change of many i see with the 6.0l its starts so dam quick in cold weather you cant belive its a diesel.
For what it's worth I just participated in a 3 day on-line survey concerning a rewards program regarding Shells heavy truck products including Rotella. X number of points per purchase or service which would be redeemable on perks such as free meals at national resturant chains, $$ off for computers, etc. I hope they implement somthing like this. I buy no less than 30 gallons of motor oil per month so it adds up with or without the perks.
All our trucks are Powerstroke Diesels. We use the Valvoline Premium Blue. Its a synthetic oil that will last for extended drain intervals. We go 5K miles. The synthetic is also more resistant to breakdown at high temperatures, such as in the turbocharger bearings.

Hi-Performance Synthetic Engine Oil
Valvoline Premium Blue Extreme is formulated with high-quality synthetic base-stocks and a boosted additive system. The hiperformance synthetic technology meets the stringent demands of modern diesel including EGR (Exhaust Gas Re-circulation)
engines operating under standard and extended service intervals in a wide variety of service conditions. The unique Valvoline
formulation is field proven and delivers exceptional TBN retention, extended drain capability, enhanced fuel economy
potential over conventional oils, advanced soot control, outstanding viscosity retention and excellent all weather performance.
The hi-performance synthetic technology is designed to meet the most demanding needs of modern low-emission diesel
engines including 2002 EGR engines from Cummins, Mack, Detroit Diesel and others.
Rotella t is a good oil. I have used it in everything for years. I would break in a new engine on dino oil then switch at around 20,000 to syn. Amzoil or Schaeffers would be my choice in a 0w30 or a 15/40 weight. Got questions? Go to http://www.bobistheoilguy.com
