slamarre Posted June 8, 2008 Report Share Posted June 8, 2008 All, I am almost ready for my 1,000 oil change and here are my options: 1- Stay with SAE 5W-20 Synthetic Blend Motor Oil and FL-820S oil filter every 2,500-3,000 miles OR 2- Switch to Amsoil SAE 5W-20 XL Synthetic Motor Oil with Amsoil Oil Filter EAO11 every 5,000 miles. I read somewhere that it is not good to switch to Full Synthetic @ 1,000. Engine should get synthetic more around more than 10K miles? Anyone can clarify this if it is true. I have a concern with option #2 since this is not the oil recommended by Ford. If the engine has an issue in before 3y/36K Miles, what tells me that Ford will not blame it on the oil? If you reply to give you opinion, it is fine. However, is there an official paper or statment that will protect me if this is happening if i decide to go with #2? Thanks folks.
