The M1-108 is the small, OEM size. Should I use it or the longer M1-110? What do all of you Mobil 1 guys use? Thanks.

 

makes no difference. you can argue till your face turns blue on the benefits of one over the other.

i've used both and have run oil analyses after each one and they're both the same.

i currently have the M-110 installed.

comes down to personal preference

 

I use the M1-110

 

I use the OEM sized one simply because it is the one recommended by Mobil1.
