Mobil 1 synthetic oil

[medrvstang01]

I'm glad someone mentioned this! I've been pretty upset that Ford started using 5W20......here are the answers.

Ford and Honda are the two first to start the trend, which most will probably follow. The Federal Government was pushing the manufactures to get better gas mileage out of their vehichles (I forgot the program name) so Ford and Honda decided to go to 5W20 to get better mileage. The mileage is nothing the human could ever see, but with all cars together it makes a difference. This lighter weight oil is causing severe stress on the motors, but Ford states if anything comes in and they do a oil test.....they won't warranty it if your running a different weight.

I've thought about this long and hard. Like I said, it's got me pissed. I've always run the 5W30 Mobil One and Mobil doesn't plan that it will be out anytime soon. AMSOIL wrote a huge article about it, you might want to check out the website. They say to use the 5W30, but they aren't the ones risking the warranty. I haven't been brave enough to go with the 5W30. AMSOIL makes the 5W20, but I've heard missed feelings on the company. I've got a 2001 and my weight is the same.....but I haven't seen any warnings about using synthetic!......
