Great oil for the old gen vehicles that need love
Really like this oil for my older vehicles. Not only does it provide awesome protection and little to no burn off, it also has properties that help prolong the life of the older seals and metals. This stuff works and works well. Been using it in all of my offroad applications in my older 4x4's. Zero issue and by far the best bang for your buck. Older engines, they love the hybrid blend oils, they benefit from both all aspects, without compromising on issues with age of the engine. Awesome product!

Castrol High Mileage 5W-30 Motor Oil
It's the only brand I've used in the last 2 cars I purchased and never had a problem because of the oil used. Last car had 270,000 miles and never an oil problem, that's good enough for me to keep buying it. I've never bought the synthetic or blend, contrary to what it shows here, thanks Walmart, great follow up.

Best oil on the market.
This is a great product and I feel like my car engine is well protected. I have 3 vehicles and I have used this oil for many years. I will continue to buy it in the future.
