I'm not picking on your post, you just raised a couple of good points IMO. Now to contradict myself, I do use Lubegard Bio from time to time... seems to lower the engine sound and allow the engine to run at lower rpms at cruising speeds. I have no objective way to measure this, so I concede it could totally be in my head. (yes, you could argue I've carved out an exception for my own use of LG...‚) Other than that I don't use a regular oil additive. I may run Rislone/MMO from time to time as a cleaner.
It is physically impossible for an additive to allow the engine to run lower rpms at cruising speep. RPMs are fixed based upon the transmission ratio, final drive ratio and tire size.
Sorry, I'm just a lay person and not a guru by any stretch so maybe I could have stated that better/more accurately. (Don't worry I'm not quitting my day job anytime soon ...‚) Anywho...my engine seems to produce more power at lower rpms by using that friction supplement by LG.
Doesn't friction require more force (since it works to slow moving parts) and fuel for your engine to do the work? And friction produces heat which effects engine efficiency as well?? Wouldn't lowering friction allow you to produce more torque/hp over a wider band, thereby lowering the need to run at higher rpms?
