Has anyone used this in there engine,trans, or final? It says on the bottle that it is great for HD motors.

 

Well it would say that.............they want to sell it.

Buy good oil and add nothing.

All Lucas oil stabilizer is a heavier weight oil with few additives. Not worth the $$ IMO. By the time you add in the cost you could have bought Amsoil or Mobil1 Vtwin.

 

Agreed.

 

Thanks for the replies. After thinking about just buying higher quality of oil makes the most sense. I have only used HDSyn 3 oil but think highly of Mobil and use that in other machines of mine. Amzoil is used in my outboard motors.
