"After 30 years of using Castrol, I found Castrol to be the world's best oil. I had tried many other oils but, Castrol made the difference and helped keep my engines together. Thank you Castrol for all the years of having faith in your products."
—Tinker Gladden Racing from Salisbury, MD
"I have a 1991 Toyota Camry with 221,000 miles. The paint is starting to go, but the engine is solid. I have used Castrol GTX since it was new. Moved from 10-30 to 20-50 at 150,000 miles, and have changed the oil every 3,000 without fail. Even at 221k, it still only uses less than a half quart between oil changes."
—Dennis from Lafayette, CA
"I have a 1979 F150 with a 351 engine and I was on my way home and it started to overheat. I have a true temperature gauge in the truck and by the time I got to my home it was pegged on 280 degrees. I know the only thing that saved my engine was the Castrol 10w 40 motor oil in it. Thank you for a great oil."
