- Great Motor Oil Review by tom
Quality Price Value
This RK 10w30 motor oil is as good as many motor oils that sell for 3 times the price. The API service rating, on this page, under "DETAILS" is not up to date. The oil I just bought has stated on the container "Warren Unilube of Dunn, NC. API . SN, SM, SL - ILSAC GF-5" so this is truly great motor oil blended by Warren. This is just another example of Rural King selling a fine product at an amazing price!!!
