I am doing my first oil change this weekend. I use mobil 1 in everything can I use it in my 300 also?

 

I have been using the motorcycle Mobil 1 for viscous clutches in my 300 for a couple of years and have not had any problems.

 

I am using regular Mobil1 15w50 automotive in my 400EX. From what I can find, it doesn't have any viscosity improvers, which is good for the engine

 

Mobil 1 is good, Amsoil is better. Both are far ahead of petroleum oil. I use Amsoil in everything I own. Top of the line synthetics are expensive, but are well worth it. For those of you who do a lot of water/mud riding, try Amsoils water proof grease for the bearings. For more info. visit my website.
