What is the technical data on this oil?
Why use it and why not use it?
I know all the things like not in my $40,000.00 truck, Use at your own risk type stuff but what about technical reasons. I'am looking for good solid reasons why not to use.
I did a flow test experiment on oils useing a walkin freezer set at different temps gravity flowing through an orifice.
Delo 400 15-40
Rottela T 15-40
supertech 15-40
pennzoil 15-40
cenex 15-40
They all flowed about the same at 0*, -8*, and -15*. The surprise came when I flowed Rottela 10-30, it flowed worse the colder it got.
I done one synthetic oil in 15-40 and that was amsoil, it flowed about twice as fast as compared to the other 15-40 oils.
I know any 5-40 would probably flow faster than any 15-40 but I want to use 15-40 until the engine is broke in. Yes I know many have used synthetic oil before recommended breakin without any ill effects. I just want to use 15-40 for now and if no one can come up with a good technical reason why wal-mart supertech 15-40 is not any good maybe I'll use that for the life of the truck as I own it.
I really don't want nor need the expense of a synthetic since I'am **** about keeping everything a pristeen as possible. I changed oil every 3,000 on my 99 and with the recommended oil change interval on the 05 at 7500 miles I was thinking about changing mine every 5,000. Like I said I'am **** and even when I used synthetic in the 99 I could not go any longer than 5,000 miles.

BlueBull has obviously done some homework on the topic. I respect your expierence and didn't want to ignore the actual topic. Just wanted you to know that I wouldn't care if it was magical oil that held up 30,000 miles and was 2 dollars a gallon. WalMart Stinks. They are dangerous and the rest of America will figure it out over time.
No-one was putting down the Employees themselves, just the Employer. The BIGGEST retailer in the Nation should be able to offer more for the folks that are making it happen day in and day out.
The Ro"smella" isn't that bad, it goes away in a few weeks.

No direct experience with SuperTech engine oils.
An Engineer buddy of mine (drives a 96 CTD) worked at Toro a few years back. They had a lot of engine related warranty claims from Wal-Mart. They traced it down to the Wal-Mart branded oil.
Gear Poet hit it on the head. Wal-mart does squeeze the lowest price from a supplier with no contract guarantee. Mixing oil brands on a regular basis in not good. Additives are not all equal and can fight.
I can hear you squeak from here, Ron. We had this discussion a few years ago. I'll stick with my Delvac 1 and change annually or every 18k, whichever comes first. If you want to go with traditional, put Delo in the truck. That is the best conventional oil on the market. I'll send you the data if you want it.
OK OK OK I hear the others already asking for the data. I'll bring it home and post it here, too.
