There is one drawback for PAO. It does not mix with the additive package. So you still have to add a group 3 or group 5 base oil to handle that additive mixing job. Even Mobil 1 has changed formulation mainly due to PAO cost. Mobil 1 has many flavors of base oil formulation over time and now has...
Red Line Performance vs Amsoil Signature,
Both great, but targets different markets. If you search for comparison there is a lot of opinions. Be careful of the statement "meets, or exceeds". The ILSAC starburst seal is paid for, same as Ford standards. So under warranty, read your Operation...
Just my view...
Catch cans collect some oil but is a restriction to the engineered design of the PCV. What oil it collects does not affect the IVD. Especially a forced air and dual injector engine.
Mazda Skyactiv engines use intake valves heated above 400 degrees, a air/oil separator before the...

I only buy Costco gas, so this is the average Costco per state. The State gas tax needs to be subtracted to see the fraud rate.
