OOPS.. Need some info. on oil

[Billieg]

I just purchased a 2007 F-350 diesel/dually and love it. The motor has the EGR removed and a Banks system with a 5" Cat back exhaust in it.

After getting it home I checked the oil and it was down not even showing on the stick. Never having a diesel before (in a PU) I put in 4 qts of STP 10w-40 SM oil to fill it up. I now know I need CJ4 oil in it but do you think the 4 qts of SM will hurt the motor or injectors?

The PO stated he just changed the oil with Amsoil so I hate to dump $80 of oil for nothing. I called him and asked him how much oil he put in and he said 12 qts. The book says it takes 15...
So what do you guys think?
Thanks

When in doubt? I also use amsoil and love it. Won't use anything else. You can call amsoil and they will answer your question. But honestly I think you will be ok. I would also look into this. AMSOIL Preferred Customer Wholesale Membership

no gas engine oil will not harm a diesel engine in the short-term. Look for this seal on the oil container for diesel engine oil.

Be sure the oil you use is CERTIFIED for diesel use, not the fake ones that Amsoil used to put on their containers that looked like the real thing but said it was "designed to meet". The reason for that was that it hadn't actually been tested to meet the requirements by the certified testing lab, but Amsoil thought it would.

Using SM oil won't hurt the engine, but could effect the emission system due to its sulphur content. That what I was told about my 07 6.7 CTD. It uses CJ-4, also.

Diesel engine has a different additive package and a lot more zinc in it for the internal gear train. The additive package helps keep higher levels of soot in suspension. Short time won't hurt but I would not run it long. It also can really build sludge on the valve stems and laqcuer on the piston ring lands fast.

Thanks guys. Live and learn.

I would really question an owner who has a 6.0 and says he put 12 qts in, the 6.0 has always needed 14-15 qts. How many times do you suppose he did this before? Forget the cost of Amsoil (good stuff, no doubt). Change the oil yourself, or have it done, and be sure you get the correct oil and amount.

Previously I have owned 2 6.0s--don't skimp on the oil changes.

A 6.0 should take 14 quarts. Use Shell Rotella.

Ya, he showed me a pile of receipts for the work done, parts and other stuff and said he would mail me a copy of them along with the spare key... still waiting..... I hope this was the first time he changed the oil.

The truck now has had a tranny flush, gear oil change, lube, radiator flush and next an oil change with fuel filters. I'm also looking into an air oil cooler so I don't get that dreaded water in the oil goodbye motor thing....

I got way over 100k miles on my '04 and 95k on the '07--if you religiously take care of it, should be ok. However, the oil cooler on the '04 imploded at about 124k to the tune of $2600--that's when I traded for my '07 and had very few problems with it.

your talking about a non issue, the 6.0 oil cooler works just like the others that followed it, not to many blown seals to leak coolant, except on ramped up engines.
the 6.0 needs CARE and feeding just like any other modern diesel engine.
mine towed us around all over this great land with just minimum issues

and 07 6.0s have to be the best ones....actually late build 06 through 07 had all the buggies worked out

I use Shell Rotella T on my 7.3L
