Oil choices for built engines

I was at Pep Boys Sunday and saw a 5 gal pail of Mobil Delvac 15-40. I assume it was syn with the Delvac name. Am I wrong?
I think diesel power and killer bee have said everything there is to say about the effects using using certain types of oil.
I'm not saying I know a lot, but I've been educated on oils, properties, uses and the science and technology behind them along with reviewing a lot of oil properties and analysis for use in industrial applications.
Only thing I could add, which has been touched on, is that for regular daily drivers you won't want to get away from the multi-grade oil. Its going to provide proper lube on cold starts and proper lube at operating temp. A standard weight oil is generally better suited towards continuous operation at a given set of parameters(not a daily driver).
For the pullers and drag racers, who don't drive run the trucks much other than the race or pull, you'll want to change oil very often. I'd bank on every second race or pull. The way a lot of oil and additives works is dependant on temp like killer bee and diesel power mentioned. Operating the motor breaks down the oil (technically shears the oil molecules to provide the lubrication). The harder you run it, the worse it does this. And generally the molecules and additives can actually bond back together when operated in a certain temp range and conditions. If your just racing or pulling and then shutting the truck down it won't have the chance to do this and will breakdown much faster.
For what its worth, I run Chevron Delo 400 5W40 synthetic. No big deal in the summer, but I notice huge improvements over several other oils in cold weather operation.

I've run Delo most of the time, Delavac "synthetic" blows the dipstick, more than once, I have had Rotella in for the last 3 changes and all is ok, dipstick is staying put, but ECT seems to run a few degrees higher. Nearly 100,000 miles on the motor.
What do you mean by blows the dipstick?
Just rambling,
Which type of oil is always a big debate . Rotella from what I understand has changed their anti wear properties zinc and phosphorus levels (environmental wackos) ,this is the rumor true or not I have no clue. Most diesel oils are high in those properties compared to conventional oils used in gas engines. With the introduction of EPA standards these elements are nil and that's why you need diesel specific oil.Many hot rodders have stopped recomending Rotella oil . SINCE NEW EPA standards in diesels and pollution devices (cats) in diesels it makes sense that Rotella has changed their blend. Ii do believe zinc and phosphorus ruins cats.
I know in my Harley that you never use gas engine oil but you use diesel specific oil. I did lots of research with my (gas) engine build and the consensus is to run VRI or Brad Penn (Kendal) The Green Oil ,OFF-ROAD oil . Brad Penn is refined her in Pa and is also endorsed and relabeled Joe Gibbs oil used in Nascar.
From what I've read Brad Penn has the highest anti wear properties and has a good what they refer to as a 'cling' film. I can tell you this stuff is slippery than snot on a door knob. I run it in my built HD motor and will in my built gas engine. I have yet to have the balls to put it in my Duramax
Just food for thought.

I used Joe gibbs on my last oil change before switching to Cenpeco
I think it would be great for the bikes.....I wasnt impressed with it in the truck though......Nothing technical but it got very thin after 3 passes
