George@VIVA started using Motul 8100 earlier this year and was raving over the decrease in engine noise (friction) and oil usage. I did some reading and decided to give it a shot. The 8100 X-Cess 5W-40 I used seemed to run smoother but oil usage didn't decrease. George also mentioned in a later thread he was considering the Motul 300V.
This week I changed to the Motul 300V "Power" 5W-40, and the decrease in friction is unbelievable. I have only hit 60 mph in 2nd gear (GT) a few times during the past 5+ years because the engine felt like it was about to throw a piston through the hood. After the 300V fill, I drove around 20 minutes or so, then hit it from 1st to 2nd. The engine smoothly reached 6500 rpms while in 2nd gear, speed was about 55 mph. I pushed it a little more in 2nd hitting 62 mph with no problem. The engine was smooth as silk. Performance increased through all gears.
The 300V is racing oil and probably shouldn't be used all the time due to lack of detergent additives (and cost). I would certainly use it for running the quarter or for a track day. My EGT was probably 100 deg lower than usual as well. This stuff is like liquid power. The difference between the 300V and Mobil 1 is night and day. 300V is an ester based oil (100% synthetic) and is quite expensive at $15/quart. I just wanted to see how good it performed. So far, it is way above any motor oil I've been around. We used ester based oils for turbine lubrication due to the extremely low shear rate and longevity. The sound of the R engine above 6000 rpm with this oil reminded me of the turbines running similar lubrication.
Merry Christmas!
