Guys i'm looking for some advice.
I've a 2008 Fatboy with only 5,000 Km on the clock.
Its been run in on the Harley 20W-50 and i've had one service which again the Harley 20W-50 was used.
I personally feel that using a 20W-50 lubricant in the Irish / British climate is not a good idea as its to heavy an oil and takes to long to get to a temperature that enables the oil to circulate properly at start up.
I was looking to switch to Mobil Racing 4T 15W-50 but mentioning this to a dealership sends them into overdrive. The are totally against the idea of a bike that has been "run in" on a mineral oil being switched to a synthetic oil.
Personally i can't understand this, this is certainly not the case for cars.
They also claim that a 20W-50 engine oil perfect for our climate.
Could anyone shed a bit of light on this ?
Has anyone had any experience (good or bad) with changing oils ?
Thanking you all in advance !
