Lucky you Dave.
Normally I never look anywhere near the diesel oil section. All our Walmarts are set up where I enter the aisle and all the gasoline oils are first and at the end of the aisle are diesel brands like Rotella, Delvac and Delo. A few weeks ago a member here at BITOG mentioned the Delo XLE in thin weights. That's what put me on a search for it. Otherwise my feet hit the brakes in the aisle, when reaching Rotella, Delo and Delvac.
Sometimes I stop in the oil aisle when I reach Supertech gas-only oils. I have-yet to buy that brand, in 50 years of oil-shopping.
