Having recently purchased a 2020 250mile 3W I was some what disappointed with the driving experience because of the oh so noisy drive train. Just couldn`t hear myself think at around 50mph in particular. But having researched a lot on the bevel box, I have changed the oil using MOTUL competition gear oil 75W140 and had a word with the guys at Crazy Horse who also recommended using Red Line additive. Well I could not believe the difference, the whine has improved by I would say 60%. Its not until the oil is really hot that it starts to whine now and no where near as bad as it was. The car is now a real pleasure and thrill to drive and people don`t look around to see what the whining noise is coming down the road towards them. Just hope that the oil success will last a while, before it needs changing again.
