Ready to Ride
So i changed my oil today, put in Shell Rotella T6 Synthetic 5W-40. Now I got 5W-40 because it was the only one i coulod find in full sythetic at my local Walmart. After changing it, I let it idle in the driveway for bout 5 mins then took it for a spin around the block. When i got back and put it in the garage i noticed the fans were on and it was sitting at 4 bars on the temp gauge. Its 35 degrees outside so im thinkin this is a bit wierd. Is this because i went with too low of a winter viscosity? Any advice if i should leave it or change it to something else?
