I have been using Mobil 1 V-Twin 20-50 synthetic oil in my 2010 FatBoy Lo since I first purchased this bike, as it is getting harder to find the Mobil1 oil I wondering if anyone has used Penrite Synthetic oil in their Harley.
I will be trying Penrite 20-60 hpr diesel oil on my next oil change, my mate who sold me the bike had just changed the oil and used the Harley brand oil which I must admit I not real keen on it's seems to me to be a very thin oil when it get's hot, maybe it's just me when it comes to oils but I think Penrite will be the go for me from now on.
your bike will love you for it everything i own uses penrite and its good old aussie oil
Is there a difference between oil used in air cooled engines and water cooled.
Very much so, and I don't think its been ignored in this thread
Harley recommend a desiel engine oil to substutute for ther own oil
Penrite recommend their Syn 20w 60 in air cooled bikes and there HPR Desiel oil is top quality and both are easily assessable
and so long as the meet the correct standards you are good to go
