Excellent value

I used the SAE 30 Break-In Oil for the first time on my new engine, and I'm really impressed. It’s a high-quality oil that provided excellent lubrication during the break-in period, and I feel confident that it helped protect the engine from unnecessary wear. The consistency is great, and it’s easy to pour and work with.

Llego en buen tiempo, y venia tal y como en la descripción. Le hicimos el.cambio de aceite a mi carro sin ni gun problema y fue mas económico que en el auto partes

It provided excellent lubrication during my engine's break-in period, ensuring smooth operation. The oil maintained its viscosity well, and my engine runs more efficiently now.

Great stuff for breaking in new motors. Used it on a Chevy 383 stroker break-in. Quality product would recommend and will use again.
