Vanos Solenoid Care
Metallic particles circulating in your oil are the main enemy of your Vanos solenoid valves. You can prolong the life of your vanos with an ultra high quality magnetic drain plug and frequent oil changes. Our drain plugs are the best on the market and we highly recommend using these with our rebuilt S54 vanos or when replacing S85 Vanos solenoids to get the best performance and longest life from the solenoids.
We only recommend using BMW Castrol10w60 or Liqui-Moly 10w60 Race Spec oil in the S54 engines, along with frequent oil change intervals, 3500 - 5k miles at most.
You can find our S54/S85 magnetic drain plug here.
