Rated 5 out of 5 by DIYDad I use Lucas oil in ALL of my engines
Lucas Oil does what it says. It coats engine parts. I have used this in all of my engines for the last 24 years. I have not missed adding it with my oil since. I have also used it for differential oil. I was impressed with the improvements. There are no down sides to adding this to your oil.

Rated 5 out of 5 by Machew Good stuff.
I have been using this stuff since my first car. My father who has been a mechanic on every engine imaginable recommended. I've ran a car dry of oil and put this stuff in and the knocking ceased immediately. I buy old cars at low prices and always immediately change the oil and add a quart of Lucas. My cars live long lives and I'm a believer that Lucas adds life to the engine as I've never had an engine fail or knock with Lucas in it.
