Re: vvt slow response code with thicker oil.
iirc, I had read that oil viscosity grade (obviously within reason and talking about 20 vs. 30 or 40) has no impact on vvt operation ... Is there a documented case that viscosity diff between a 20 and 40 can cause issues after warm-up? as both oils are very viscous when cold. or is it the sludge that causing the code?
just curious since I'm using 30 instead of 20 and was kind of even considering a light 40 but haven't pulled the trigger yet.
