There are more myths about synthetic oil than you will ever know. These myths are carried on by ignorant people. Do some research about synthetic oil and you will learn a lot.
Also, don't ask for oil brand recommendations. That's like asking which brand of clothing, motorcycles, cars, etc that somebody likes. It's merely preference. Some people will swear that their favorite oil has given them an extra 20 horsepower or lowered the engine temperature 50 degrees. It's mostly bull****. You'll need to look for oil comparison tests if you want to get to the bottom of the facts. Oh and if you do a Google search don't be fooled by the "facts" that are listed on the twenty million Amsoil "dealer" sites online. Search elsewhere.
