Rocky, the Delo, as a diesel "fleet" oil is only in the conventional 15-40 weight. My last jugs were bought at WMT for $11 a jug. BTW, as diesel oil, it gets dark in short order ( 5 hours run time) due to the detergents, while the Brad Penn I am using now stays "green" for a thousand miles.
I do the purchasing for a major elevator company in the midwest and I purchase hydraulic oil by the boat loads. One Of my suppliers is a Chevron dealer, and when he was in here a couple of days ago, we were were discussing of course engine oil and ZDDP additives and we were talking about the Delo, and he told me I can actually get Delo in 10-30.
I dont believe it's anything you can get off the shelf any where, but it can be purchased thru a Chevron dealer.
Just about the time I think I have it figured out I find something that changes my mind about all of this. I just went back to http://www.bobistheoilguy.com/
and read cover to cover Motor Oil 101-201 and actually took my time and made a concerted effort to comprehend what he wrote about motor oil in general and it changed my mind about the why and how comes you would use a specific motor oil, and because of temperature and lubricating concerns in a cold climate, I have changed my mind about using a 15-40 oil, and I can't wait to get the 20-50 that's in my engine out of there. I believe it was 18* this morning. Gene I also have become Un-Puckered, I got a good chuckle out of that one.
Beatin' a dead horse with this thread. All this info is posted and re-posted all over the net. Still a bunch of opinions with no definitive info. Every company has a different opinion and it reflects what their paid experts say. Guys here run all types of oil and have success. It seems to me the most important factor is proper break in of a new motor/cam. Once that is done, oil choice is probably not so critical.
Pre-lube a new motor with proper cam paste. Time it correctly, fill the carb with gas and fire it up right away and bring the rpm's up to the 2000 level or so. Let it run a bit and it should be broken in and oil choice shouldn't make much difference.
Of course, guys will read this and tell of using a used cam given to them, their old lifters and that they have now put 60,000 miles on that motor. This does happen. There is nothing definitive in this subject.
Sorry I'm beating a dead horse as you say, I guess if I know the answers I wouldn't have asked the questions now would I
And most of the answers all over the internet as you say, generally leave you as confused as before. Because every question gets answered with use this, use that use X,Y, Z and no one can tell you why!
I have actually had the time this week to research in depth the things that have concerned me. This oil situation so to speak does interest me and I think I know more about oil now than I ever thought would be necessary.
You are absolutely correct! After a break in, my findings I have learned (By Actual Facts) that oil choice's only concern should be what weight is best for your engine and whether or not you want synthetic or mineral. So dead horse or not, I'm not the only guy who didn't know what is right or wrong oil wise, but I made an effort to educate my self! I would expect someone else will be around the corner soon asking some of the same things I did, and hopefully I will be able to point them in the right direction so they can educate themselves also!
So all is well in my world oil wise now. So now that we have that horse tenderized, we can have a BBQ!
So as before Thanks to all who helped me understand!
