Looks like Dollar General has what old car enthusiasts have been begging for!

Quotes from the article:
"The front label of the DG 10W-30 oil looks like any other oil, but a warning on the back of the bottle advises that the product is 'not suitable' for 'engines built after 1988.'"

and

"Our expert says that another DG oil on the shelf, SAE 30, is meant for some small engines like select lawnmowers or air compressors, but we found it on the auto shelf. Its warning reads 'not suitable' for 'engines built after 1930.'"

And the GMA is filing a suit against them?! Wow. I know guys that would pay EXTRA for that!

GMA is not suing, but consumers via a class action. At least 2 suits, if not more. One in California, and one in Houston Texas. Both filed in December of last year.

I personally use the SAE 30 for my tractor and for my overdrive transmission in my MGB. Both specify a non-detergent oil. A modern detergent oil gets whipped foamy in the B's overdrive and then won't engage properly.
