5 Harley's since 1981 and they all used Harley Premium Petroleum Oil. Never seen the need for synthetic and had a few over 75k mi

 

I steal mine from the grease pits at fast food restaurants.

My exhaust smells like french fries....

 

3 in 1 oil, been around for years

 

I use "FaMunda Cheese" myself.
Easy to use and have a neverending supply

 

A friend of a friend's friend who works at a garage somewhere said he heard from some old fart to use a 50/50 mixture of Syn/Dino. Add in a couple of drops of Teflon to help it flow easier and you're golden.

 

I've been using, "Holy Annointing Oil". I hear the Big Guy uses it in his bike.

If it's good enough for him...

 

Caster "R" bean oil....keeping it old school.

 

Wolf's Head Golden 30wt, it'll never let you down

 

Oil thread opinions are like navels, we all have one.

 

I use Oil of Olay. Quite pricey, but it makes for a visibly younger looking motorcycle with reduced signs of wear.
