It's cold here in the northeast like pretty much everywhere else north of VA. was thinking about adding some of this Liqui Moly LM20004KT has anyone tried it?

Snake oil? or works?

i would simply change the oil to 0w40 without changing a oil filter
i'm using bmws in winters with 1 or 2 months of snow for 13 years

Just changed to 5w-30 mid December. Car is getting up in mileage it just went over 160k.

Mine does that sometimes and is pretty loud after I do an oil change.

Pretty much goes away after it gets warmed up.

Have you ever removed and checked your VANOS filters/check valves? If they are partially blocked they can restrict oil flow to the lifters or if the check valve has failed, the oil will not be retained in the galleries when the engine is not running. This might also cause lifter noise.

I should check those. I am occasionally getting the annoying ticks.

I have not yet and I know I have clean them. I had planned to replace the solenoids and clean the check valves but winter is upon the NorthEast and my garage is occupied with two projects and two tractors at the moment. So it most likely will be in March.
