So just changed oil last week and ran Rotella this time and I swear I keep smelling burnt oil and I have been all over this truck 20 times in the past week looking for a leak to no avail. Is this normal or am I tripping balls? I have always used Schaffers 7000 before and never noticed/smelled it. Between this and the damn typewriter clicking being worse on Rotella I think thats the end of this oil. Driving down the road feeling like a circus clown.
