Just a quick question .... do I need to use 15W-30 Mobil 1 engine oil in stead with the 10W-30 on my 15K + Evo ? Thanks.

 

use 10-30

 

With the minimum of oil analysises on this website, i would initially say "no". No need to go directly to a full 15w-50 load. But, thickening the 10w-30 with maybe a quart of 15w-50 seems a good idea to me.

With the high oil temperatures and the increased bearing loads on turbo engines, running a 30wt seems low. ESPECIALLY a light 30wt like the Mobil 1 line.

ferb!
