Bests & Worsts Reviews from Amazon

I have 2005 Ford F-350 with the 5.4 Triton V-8. I bought the truck used with about 159K miles on it. It had a little bit of tick in the engine, but no biggie I thought. I changed the oil as soon as I got it with Pennzoil Platinum full synthetic 5W-20. Decent oil, but the tick didn't get better. May have gotten a a little worse actually. Kept the oil in there for about 1500 miles, and decided to try something else. Went with this Castrol Edge 5W-20 and K&N oil filter. I cranked the engine after changing the oil, and I was literally stunned at how quiet the engine was. NO tick AT ALL. I was flabber-gasted. Stunned, shocked, amazed, wow, blown away, etc. Whatever you want to call it. Ive always changed my own oil, but never really thought an oil could make that much difference. Well, I am a believer now, and will never switch to another oil in this truck. It has almost 161K miles on it, and it purrs like a brand new engine. Its unbelievable how this oil eliminated that tick. Your results may vary, but as for my 5.4 Triton, it LOVES this oil. And I am not one to write a review on just anything, but this was definitely worth taking the time to write one. Thank you Castrol for making such a great product.
