Is 0W-20 Motor Oil Suitable for Use in Hot Climates
Okay, I am having trouble believing that 0W-20 oil is thick enough for the Florida heat (in summer). I have a new Tacoma. I have no problem with the 0W part (cold starting) that seems good but 20 weig...

Does Changing from a Non-Turbo Engine to a Turbo Engine Alter the Oil Viscosity Recommendation?
Hello, I've always been a fan of Mobil 1 fully synthetic but today something really crossed my mind. First off, I drive a Mitsubishi Eclipse with around 90k on the motor. The car is originally non-tur...
A turbo does put extra stress on motor oil but it sounds like you made the right choice even before the turbo was installed. That is, you are already using high quality synthetic oil by choosing Mobil...
