Re: Who is running Synthetic oil?

I've been running Mobil 1 Synthetic in it since I bought it back in 2004. I've used it in all the Mustangs I've owned

Re: Who is running Synthetic oil?

Stock motor I always ran Mobil 1 full synthetic. 5W-20 the first few years, 5w-30 after that. When I pulled the valve covers the top end looked great (around 80k miles)

Built motor I run Driven fully synthetic 5w-50 (cam bores are a little loose, per the builder)

Daily beater 3.5 ecoboost got motorcraft blend for years, doing my own oil changes now I'm using Mobil 1 full synthetic.

Re: Who is running Synthetic oil?

Been running Castrol Edge 5W20 and it's been nothing less than the best thing I've ever run. The OE Motorcraft had the engine making more noise, but the Mobil 1 was my worst experience. Killed my fuel mileage and ran so sluggish, I got it out within days. Heard such great things about it, I tried it a few years later to give it another go, same results.

Mine is noisy at startup when it's warm/hot outside after it has sit for several hours. When it's cold out or even spring-time first start, it isn't noisy. It's odd. I've been using Amsoil 5W-20 for the past two seasons. I use Motorcraft oil filters, but it does it with the Amsoil filter too. I've only got 72.5k miles, so I don't have any reason to believe it has a problem. Does this mean 0W-20 would help?

Re: Who is running Synthetic oil?

Mine was noisy at startup with Mobil 1 5W-20. Switched to 5W-30 after reading a thread from a Ford modular engine engineer on Corner Carvers who said to not use anything thinner than 5W-30 after what he saw on their durability tests on these engines. No more startup noise since.
