Easy open and easy to pour! No clue if it actually working or not but definitely makes me feel better putting some in once in a while!

normally use Lucas but went on a long road trip and forgot my bottle. my car requires upper cylinder lubricant. did basically the same thing. A bit more thinner than Lucas so may be better for high compression engines.
