Where is conventional oil 10W-30 at stores?

Ok, good luck with that
Unless your a PhD chemist my experience using T6 trumps your internet opinion. That experince is close to 300k miles in multiple gas engines from POS lawn mowers to 12k rpm R6 race bikes.
A 4.0 while burning cleaner has less shear stress and thermal loading than the oil in a diesel. A 4.0 Is very well lubricated by T6.:
 
I fully support your god given right to run diesel oil in your gas 4.0, it's America, do what you want, I don't care
(I run T6 in my motorcycle too)

I did some reading on Diesel oil as its cheaper and more readily available (In Australia) while the high Zinc content in diesel oil is really good for gas vehicles many now have other additives that are caustic and not so good for gas vehicles .
I am not disputing diesel oil use argument but just commenting to say some modern diesel oils are bad for gas vehicles so you have to read the additives carefully. :)

I had trouble finding 10w 30 non synthetic in Australia anywhere apart from top of the line very expensive oils and the reason I am now shifting to 15w 40 next change as its so readily available and cheap for good brands.
I had to get my 10w 30 from a gas station last change and why I looked up diesel oils.
In California you should have no problems running 15w 40 in summer the difference between them and 10w 30 is zilch in a warm or hot climate, 10w 30 was recommended by Jeep but last study was in the 1980,s and never updated they just kept recommending 10w 30 for summer 5w 30 for very cold start up temps.
Every mechanic even jeep mechanics in Western Australia have recommended 15w40.
There was a recent thread discussing engine oils because a Mexican export TJ had a 15w 40 information sicker under the hood even though the oil cap still said 10w 30.

Finally found a Pennzoil high mileage oil at walmart at right price. There's no mention of word conventional or synthetic or synthetic blend so I assume it is conventional. Thanks everyone for your help.

Not sure if you read the same thing I did, but I thought this was a pretty good read. I'm curious if they have changed the T6 formula much since this forum post.

Like many I used to run whatever was cheap, for me the napa 10w30 made by valvoline, but according to this it is one of the worst options for additive packages. I've since switched to T6 about 40,000 miles ago. Have I been able to tell any difference, no. But this guy seems to know way more about oil than me and his reasoning seems sound, so I went with it, and T6 is just as cheap as anything else.

Probably from the first time I posted it in the other oil thread you were in. I don't care if you do or don't, but I doubt anyone can absorb all of it in one reading
 
Ive ran rotella 10w30 synthetic blend in my 4.0 for 70k miles without a leak. Only oil i have put in it since i bought it.
