castrol motor oil

this is a great oil for your car. I've using Castrol oil on all my vehicles and here's the results. I have a Toyota that has 238 plus k miles and it's still running strong. I just opened the valve cover to replace the gaskets and the valve train was clean. you can't go wrong by using this brand of oil and Walmart has the best price in town or anywhere else.

Quality motor oil

Have been exclusively using Castrol motor oils for over thirty years. Have been very pleased with their performance. Have driven over a million miles and have never had an engine failure. I always change oil and filter according to the vehicle manufacturers' recommendations. The full synthetics have a significantly longer change interval than the conventional oils.
