Greta bought this oil, and it’s a great deal. It’s good quality oil and it ships fast. I bought three 1-gallon jugs for $20 and change, I think. It was a good deal, and it keeps my engine protected. I have plenty of oil for when I do oil changes around the house on different vehicles, and I also use it in my mower and other things. I haven’t had any issues using it in the past, so I recommend it. But everyone has their own opinions, so you should decide for yourself. But one thing’s for sure: this oil is a great deal for the price.

It’s Valvoline of course it’s a good product

The majority of jeep 4.0L owners think modern oil is bad and can't protect a old flat tappet engine. I have been using standard Valvoline 10w30 for 30 years in the 4.0 with no issues. I switch to high mileage synthetic blend after 100k miles for its cleaning and reconditioning properties. The high mileage synthetic blend has all the protection a flat tappet cam needs with modern technology.

Well it's oil... so yeah it worked.
