Not Ranked
Most oils that advertise as "fully synthetic" are not. In my experience Amsoil is fully synthetic and one of the best oils on the planet. Closely followed by Redline. Most Mobil 1 and Castrol street oils are dumbed down versions of synthetic oil and but they are solid performers, just not top tier....IMHO. I use a 5w-40 Mobil oil that is fully synthetic (its made for diesel engines). I want a relatively thin oil (the 5w) at start up and a thicker oil when the engine is hot and it contains a very high degree of additives (detergents and anti wear ingrediednts) usually not found in most street oils. So I believe I have the best of both worlds. If I wasnt using Mobil 1 5w-40 I would use Amsoil 5w-40. But car enthusiasts and their oil opinions run deep and emotional, and many are not based on facts. I just want the best oil for me and my car... everyone has different preferences... it can get complicated ....  |
