Lucas Synthetic 0W30 Racing Motor Oil 5

have used other brands synthetic oil and simply put none can compare to lucas oil and what they have achieved. 1st noticeable differece is the feeling of raw power everytime you turn the key, throttle response, increase in horsepower 2nd is more mpg's and longer oil change intervals and cooler engine temps. guess thats why they are the official oil product of the NHRA. motor oil companies would have to produce more 20w/50 as a standard just to keep up with lucas oil 5w/30. no shiny labels no fancy bottles no outrageous claims just Lucas oil.
