Great Break-In Oil for Engine Longevity!
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.

Works great
I do a lot of engine rebuilds on older engines that require the zinc additive in the oil, so the Lucas brand is outstanding and works great.
