Lets talk about Earl---OIL
I am sure this has been asked a hundred times but I am a bit confused as to oil designations and what to use When.
Since new my 02 7.3 has had a steady diet of Rotella T 15W 40 purchased at my local Sams club.
This is the only oil I can find that says for Diesel.
I use it year round!
Am I doing anything wrong?
Should I be useing different viscosities here in NY durring the winter?
Is there a better oil I might find at a reasonable price elsewhere?
Thanks
Gary

The oil will warm up quickly enough.
If you really want to do something more for your truck, switch to 5-30 in the wintertime, or get some Rotella synthetic 5-40 weight instead of the 15-40. Much easier starts on the cold winter mornings.

Use Synthetics in all my other vehicles but there is a big difference buying 5 Qts. Vs 15.
Think I will ask and see if they can get the lighter viscosity for the winter months.
At about 4 gallon per change a 55 gallon drum is looking better all the time.
I always believed oil is cheaper then engines but this past year that may not have been the case!
Thanks for all the great info here. Sure is great having knowledgable folks to talk to and get great advice from.

Price of Oil
If you have a Costco near by it's a bit less $ but they only stock Chevron Delo 15/40. WallysWorld's advantage is they stock the MotorCraft filter.

Also, if you don't like changing 4 gallons of oil every few thousand miles, a lot of people have good luck with a bypass oil filter and extended oil change intervals.
I'm trying it - but don't have enough info/experience yet to help. Only have about 6k miles on my oil at this point.

I read a big article about that. Think it may have been AMSOIL that has a filtering system so you never have to change it again.
Not too sure I would trust that but think I buy a case of the RT at Sams for just over $30 so two cases, $60 gets me three changes plus the filters. Not real bad in the grand scheme of things.

I am thinking 4000 miles is about the right intervals with my driving and usage as my truck rarely pulls much of a load and almost never in dusty and nasty conditions. The worst it sees is cold start ups here in the NY mountains.

Rotella 15-40 has worked great for me but I'm in North Texas where the winters are mild. I've been thinking about trying the synthetic if I can find it in bulk for the right price. Haven't caught on to the extended oil change setups yet. Still too old fashioned at 3k miles between changes. Too much money wrapped up in my engine to let something like oil break it down.

Hi onebuilder, I am not sure if diesels fall into this but I read very good report by Consumers Report, whom I trust much further then most, regarding oil change intervals.
The long and short was when useing good oil in a clean engine they found no appreciable breakdown in the oil properties for well past 7000 miles.
According to their testing it is a waste to change oil every 3000 miles in todays engines with the quality lubricants we have.
Completely different story if the vehicle is pushed hard or used in extream environments but for normal use there is no need to be dumping perfectly good oil at the old 3000 mile intervals we grew up with.
Your mileage may vary but I am quite sure I am wasting good oil streatching it out to between 4-5K.
Again, I have seen nothing regarding diesel engines but this could certainly be a part of this discussion.
