Engine oil

[pfuller3124]

What type of oil should I use in a 1994 ford 3930 Diesel engine ?

 

[Dingeryote]

Plain old Rotella 15-40 will do just fine.

:welcome: to TractorByNet!

When I got my first diesel 28 years ago, I didn't know diesels required a different oil than what I used in gasoline engines. When I found out, I switched to Rotella and have used it ever since.

Rotella is ok but there are better oils for the same money. Delvac, Dello 400, ect. Any in 15W40.

Rotella is the McDonald's of oil.

Do you have any UOA or VOA proof (that you can post) that show 1 of the oils you listed is any better/worse than the others listed

 

[Soundguy]

in your are / climate.. any C rated 15w40 is liekly fine.. even walmart or store brand.. You could also run a 10w30 C rated in the cold times.. or a 5w40 C rated syn oil.

I'd make my oil type / brand choice based on what i did with the tractor. how often it was used.. how many hours it saw.. and what your service schedule is.

"Better" Is actually relative.

Plain old Rotella T is the standard by which all others are measured. Some are "Better" due to add packs that address one aspect or another slightly better, most however are not.

If unique demands are made, then by all means, either a more frequent change interval or using something else that better fits the unique requirements should be used.

In the end however, the baseline is still plain old Rotella, and until UOA indicates a need for something else, one cannot honestly say another is "Better".

As has been said, any good quality 15w-40 diesel rated oil should be fine.
I have 6 diesel engines, so I buy mine in 55 gallon drums, and get whatever the bulk plant has the best price on. I've used Rotella, Delvac, Delo, XD-3, etc. The last two drums have been Mobil Fleet.

 

[Soundguy]

we use plenty of bulk mobil products where i work.

ever had an issue with them.

 

[GYPSY]

any diesel rated oil with the viscsosity rated for your climate..try walmart, theres a million of em around.

 

[Z71]

Aren't most oils the same?

Nope. Just like any other product you buy they are built for profit at a certain price. Some use cheaper ingredients so they can sell for less. How many times does the average oil change hands? The manufacture sells it to a jobber, he in turns sells it to a dealer, and they in turn sell it to a store where you buy it. 2, 3 or more businesses made a profit on the oil before you bought it on sale.

I have a vechicle with a Cat 3304 in it. The dip-stick states "DO NOT OVERFILL". What happens if you do overfill the engine with oil; what damage can be done? - stoneseeds.

Depends on how over full you're talking about. A little probably nothing. A lot in time probably will destroy the engine. Every engine that I've ever seen has this written on the dip stick or in the owners manual. If you would like to find out what will happen. over fill yours ,run it ,and in time, let us know what happens

No, just lots of reading. My ex's father actually worked for Shell till 2 years ago.

Not saying its a bad oil, just saying at that price point or cheaper there are others that are better.

I can't see how you can make a statement that the other oils that you mention is any better than the other without a UAO or VOA . You have no proof ! Do you happen to know the TBN of Virgin Rotella, Delvac,Delo, etc, ? these are the oils you listed ..Oil companies change their formulas from time to time. The 1 that has a better VOA today may not be better next week ,month, yr,etc,

 

[Z71]

TBN (Total Base Number)

TBN, mg KOH/g, (ASTM D2896)

Standard/Range 7.39 to 9.66

Shella Rotella T 9.05
Mobil Delvac 1300 9.66 <------------------------------
Chevron Delo 400LE SAE 15W-40 7.39


Shell is the worlds largest oil company so it stands to reason you will find it cheaper and in more places because they can absord smaller margins in order to get more market share.

True. I am just going off what a professional who has 30 plus years in the Lube Business told me. He is a trusted friend and worked for Shell.

I personally use Monil Delvac on his recommendation for both diesel trucks, tractors, and marine applications. In synthetic for diesels I use Mobil 1 5W40 diesel.

It has been my experience that, the oil companies are always playing with their add packages. If he worked in a lab he would know this..Oil that was good for a diesel in 05 isn't necessarily good for a diesel in 2013
